All about the lawn composter
Compost contains over 1 billion living organisms/cm3 and is sanitized by the work of nature, making it a valuable fertilizer that provides your plants with many defenses (e.g. penicillin) against diseases, fungal attack and pests. The SUPERCOMP offers the ideal living conditions for the reproduction of compost organisms, which are responsible for processing the organic waste (complete ventilation even in the inner core of the pile) for the rapid production of nutrient-rich quality compost.
Sprinkle fresh compost in the garden under shrubs, trees, on the lawn, and lightly hook it in the vegetable garden.
The compost removed from the storage chamber can be stored outdoors until it is used in the garden without affecting the soil and air. In addition to the fertilizing effect and pest control, compost also serves as a water reservoir and soil improver.
The answer is: yes, it works. The compost pile no longer rests on the ground with its full weight, but is supported by a sliding and supporting device approx. 25 cm above the ground. This means that the pile is also ventilated vertically and completely from bottom to top in the inner pile core from the ground (chimney effect).

-
As was determined in extensive test series by the Joanneum Research Institute, the vertical ventilation of a SUPERCOMP enables the composting of exclusively pure lawn clippings without the addition and mixing with other materials. The same applies to the application with leaves.
Simple answer: No.
A SUPERCOMP creates a composting result with the help of its sliding device, free of odors and without the annoying work of turning. If you want to achieve an even faster and qualitatively better composting result in terms of nutrients, it is recommended to mix highly nitrogenous lawn clippings with carbonaceous waste. This also increases the quality of the finished compost.
Experienced garden owners know: freshly cut grass layered on a compost heap rots and smells very strong.
Why? Fresh grass and lawn clippings are high in nitrogen. Lawn mower clippings also have a dense and fine structure and are very moist. In the case of a pile lying on the ground (without the SUPERCOMP-support device), the lawn clipping pile becomes compacted and lack of air can occur. These compacted areas are an ideal breeding ground for the formation of putrefaction nests (the excess of nitrogen additionally reinforces this) and the associated unpleasant odors.
Conventional composters (mostly from the budget segment) without special technology are nothing more than compost heaps lying on the ground in a plastic covering, which often lets even less air into the heap than without a covering. With these composters, according to the instructions, the grass clippings would have to be layered with leaves and other waste. If you want to avoid unpleasant odors and also expect a reasonably quick composting result, you should dismantle and turn these composters regularly (an interval of 14 days is recommended).
If you are considering purchasing a composter “only” for lawn composting, you should definitely purchase a composter with appropriate technology.
Note: Investigations on composting plants with conventional windrow composting showed that there is a renewed lack of air as early as 24 hours (!) after the turning process, as the material collapses again and compaction sets in again.
Depending on the climate and location, it can be said that a SUPERCOMP 350 liter can process a green area of 300 - 500 m2 when filled regularly.
The SUPERCOMP was tested by the renowned institute of the Graz University of Technology, Joanneum Research (Austria), in the "grass clippings reactor garbage can" test arrangement and the following results were obtained: Based on a total throughput of 910 liters over a period of 12 weeks and a residual volume of 160 liters, this results in a reduction in volume of around 82 percent. The reduction in volume was not constant but peaked in the 6th to 8th week under the given test conditions. Over time, the average reduction in volume was around 35 percent/week. In relation to the compost weight, this resulted in a weight reduction of around 150 kg within 12 weeks of composting.
The composting of grass clippings in a SUPERCOMP of exclusively fresh grass clippings leads to plant-compatible composts after a composting period of 12 weeks, a reduction in volume of 80% and a reduction in organic components of 64%.
In comparison, conventional compost heaps go through a rotting period of approx. 12-24 months under unpleasant side effects!
All about the rapid composter
- A compost heap must be aerated as well as possible. If this is not the case, the process comes to a standstill, takes much longer (up to 24 months) and can develop unpleasant odors due to rotting. The SUPERCOMP is ventilated completely vertically from bottom to top with the help of its sliding and supporting device (chimney effect).
- Compost heaps should not be moved, as the compost creatures (especially the compost worms) will immediately flee if disturbed and the composting process will have to be laboriously restarted. With a SUPERCOMP eliminates the otherwise necessary turning (= moving) and the composting process runs undisturbed.
- The environment for the living organisms should not be too damp or too dry.
A composter protects the pile from sun and rain. In extreme weather conditions with constant heat or rain, you can quickly restore the ideal conditions yourself by adding "woody" materials(if there is too much moisture) or by "watering"(if it is dry). But don't worry: this happens extremely rarely. As long as you SUPERCOMP with fresh and moist materials, no problems are to be expected.
To summarize: A SUPERCOMP composter with its patented sliding and supporting device provides the ideal living conditions for compost organisms (1 billion organisms per cm3). This allows them to do their work at turbo speed, multiply ideally and ensure a quick harvest of nutrient-rich quality compost.
A SUPERCOMP wooden composter is made of domestic pine thermowood in durability class 1-2 (tropical wood quality). Using a completely organic thermal process, the wood is heated in a controlled manner to extract the substances that wood-destroying microorganisms (fungi) can live on (where there is no food, there is no fungus).
The wood is protected on the inside with attached PP hollow-chamber multiwall sheets. Polypropylene is considered the most environmentally friendly plastic and is fully recyclable. The intelligent hollow chamber system saves valuable raw materials compared to solid plastic.
The positive properties of Thermowood:
- Increased durability (against fungal attack and weathering) - even inside the wood
- Reduced swelling and shrinkage
- Increased dimensional stability
- Reduction of internal stresses in the wood
- The wood's equilibrium moisture content is reduced, i.e. with the same ambient temperature.i.e. in the same ambient climate, the moisture content of Thermowood is up to 70% lower than that of untreated wood
- New color shades can be created, ranging from a warm brown tone to the black of smoked oak
- All color changes are consistent and homogeneous across the cross-section
- Better thermal insulation properties than untreated wood
This is made possible by the adequate air supply to the air-loving (“aerobic”) compost organisms that are responsible for the composting process. Compared to the composters from SUPERCOMP, conventional compost piles are often poorly ventilated inside (pile core), which means that the air-loving compost organisms “toil” under considerable air shortage. The result is a slow composting process (up to 24 months), which is often accompanied by unpleasant odors due to putrefaction.
With its patented sliding device, the inner pile core in a SUPERCOMP is also completely ventilated from the bottom up (chimney effect) because the pile no longer rests on the ground with its full weight. Compaction, as with compost piles or composters without technology, where the compost material lies on the ground with its full weight and only allows insufficient air to pass through, does not occur here.
Continuous ventilation is primarily responsible for the composting process, because if the compost pile is well ventilated, the compost organisms work much faster. Unpleasant odors are avoided and you can process significantly more waste in the same time with the SUPERCOMP.
SUPERCOMP composters also do not have to be turned. Why? The pile does not rest on the ground with its full weight and material can be easily and conveniently removed from the harvesting chamber with a shovel. With conventional composting as well as with composters without technology, you should turn the pile regularly for ventilation (= shovel over, at least every 14 days, the more often, the better and faster the harvest). Secondly, you can hardly remove finished compost material under a pile weighing about 100 kg and resting on the ground. For this purpose, the composter should be dismantled, the pile moved and reinstalled in layers. Thirdly, the work of turning is often saved in practice, as it is very laborious and involves heavy odor pollution.
- A compost pile must be ventilated in the best possible way. If this is not the case, the process comes to a standstill, takes much longer (up to 24 months) and can develop unpleasant odors due to putrefaction. The SUPERCOMP is fully ventilated vertically from the bottom up with the help of its sliding device (chimney effect).
- Compost piles should not be moved, as the compost organisms (especially the compost worms) immediately flee when disturbed and the composting process has to be laboriously restarted. With a SUPERCOMP, the otherwise necessary turning (= moving) is not necessary and the composting process proceeds undisturbed.
- The environment for the organisms should not be too moist and not too dry.

The SUPERCOMP is made from food-safe recycled plastic (polypropylene) in a special process with the addition of lime to further strengthen it. Nevertheless, a certain elasticity is retained, which balances out the forces acting on it and counteracts the risk of the plastic cracking even better in extreme weather conditions (hard plastic cracks quickly in extreme heat). The side "uprights" are reinforced and continuous slats additionally brace the construction to ensure maximum stability. When the composter is filled, it stands SUPERCOMP rock-solid, so that even strong winds cannot harm it. Polypropylene is considered the most environmentally friendly plastic and is fully recyclable.
The base plate is made of weather-resistant polypropylene (1,500 g/m2) and is 8 mm thick.
The base plate protects your ground from contamination and makes it easier to remove the finished compost thanks to the smooth surface. If you place the composter on paved surfaces such as terraces or concrete, the base plate is definitely recommended. If the composter is placed in the garden, you can SUPERCOMP on bricks or do without a paved base. This is also not a problem. However, make sure that the composter is set up horizontally (level the area before installation).
Organic waste is a valuable raw material for your own fertilizer production. Everyone knows the prices for compost soil in garden centers. In addition, you help the public waste disposal service to save considerable costs of up to EUR 200 per year/single-family house, as your organic waste no longer has to be collected. Check with your municipality or city administration to see if you can cancel the collection of organic waste. In some cases, municipalities will reimburse the costs or give a bonus for this. You also contribute to climate protection and reduce particulate matter pollution, as you relieve the environment of truck transport. Overall, both households, municipalities and the environment benefit from home composting.
The pictures show an experimental setup at the Institute for Process Engineering at the Graz University of Technology, to which 300 l of pure oranges were added only in the parts per thousand range of lime, rock flour and sewage treatment plant substrate in the sterile laboratory environment; after 8 months, the certainly difficult task of converting exclusively oranges into compost was completed - see pictures 1-3.
In a series of tests at the Institute of Process Engineering at Graz University of Technology, only oranges were composted in a SUPERCOMP only oranges were composted. This test can be considered so difficult because oranges take much longer to decompose than other types of waste and, due to their high nitrogen content, must be mixed with other organic waste as much as possible in order to become compost at all. The purer the waste, the more difficult it is to compost. For example, attempts to compost surplus oranges in Sicily (Italy) using windrow composting were only successful when 2/3 of other biowaste was mixed in.
The pictures show the experimental setup at the Institute for Process Engineering at the Graz University of Technology. Lime, rock flour and sewage treatment plant substrate - only in the parts per thousand range - were added to the 300 liters of pure oranges in the sterile laboratory environment. After 8 months, the certainly difficult task of converting exclusively oranges into compost was completed.
As the SUPERCOMP is largely free of unpleasant odors, you won't have any problems with your neighbors. If odors do occur, then there is something wrong with the composting process that can be rectified quickly and easily. In this case, we can help you here.
We show you a photo. This composter has been located in an inner-city courtyard (6 houses with approx. 130 residents) since 2008. A neighbor tried to have the composter banned by the authorities, but this was rejected by the authorities after on-site inspections due to a lack of evidence of odor nuisance. If you only want to compost your own waste and operate the composter yourself SUPERCOMP yourself, composting in residential areas with allotments is not a problem.

If a settlement wants to compost together, we definitely recommend the installation of a responsible person who should regularly carry out the following activities:
- Check for contamination of the waste
- Check for moisture content and composting process
- Removal of finished compost
Experience shows that composting in settlements with “anonymous“ residents leads to problems, as many people unfortunately lack the necessary awareness for composting.
The Joanneum Research Institute of the Technical University of Graz (Austria) conducted empirical studies on the practicality and efficiency of the individual composting systems SUPERCOMP over 12 weeks and issued the following TESTIMONIAL:
TESTED BY JOANNEUM RESEARCH, GRAZ – AUSTRIA
JOANNEUM RESEARCH conducted empirical studies over 12 weeks on the practicality and efficiency of the individual composting systems SUPERCOMP .
Essential innovative system components include sliding surfaces, which act as sliding wings to slow down the material flow during downward movement, thereby effecting a continuous composting process with optimized vertical aeration. The physical basis for this is the different frictional forces between mature compost and immature composting material, which leads to the formation of support lines for the stability of the composting material, thus enabling continuous process control. The selected surfaces and angles of inclination of the sliding wings lead to the formation of support lines in the composting material within the first 6 weeks.
Reactor barrels with different material properties were examined with a filling volume of 300 liters (wooden container) and 350 liters (plastic container). The aim was to develop data on nutrient balance, operational and functional stability, as well as the quality of mature composts produced during practical operation. The feeding took place continuously a) with organic waste garbage and b) with fresh grass cuttings.
Reactor barrel grass cuttings and reactor barrel organic waste garbage
Based on a total throughput of 910 liters over a period of 12 weeks and a residual quantity of 160 liters, the volume is reduced by around 82 percent. The reduction in volume was not constant, but reached its peak in the 6th to 8th week under the given test conditions. Over time, the average reduction in volume is around 35 percent/composting week. Based on the compost weight, there was a weight reduction of around 150 kg within 12 composting weeks.

Summary
The composting of organic waste using SUPERCOMP with both test setups – one with exclusively fresh grass clippings and the second with organic waste from kitchen scraps – leads to plant-compatible compost after a decomposition period of 12 weeks, a volume reduction of 80% with a reduction of organic components of 64%.

A note on lawn composting
Based on loosely filled grass cuttings, the volume reduction is even greater: in practice, 50% in the 1st week, as the material not only shrinks due to the composting process, but also packs together after filling in the composter due to its own weight.
Yes. We have many customers in densely populated areas who compost without any problems on their terraces with the SUPERCOMP . If you want to keep it very clean, we recommend purchasing a drip tray (hardware store), as some leachate may escape from time to time (only in extreme humidity). Simply place the composter in the tray. If the tray should be filled with a lot of water, empty the tray.
In any case, you should also order the base plate (only for the plastic composter; it is included with the wooden composter) and “inoculate” the SUPERCOMP after installation.
All about the Thermocomposter
- Compost worms work most effectively at a temperature of 15°-25° and ONLY with sufficient air supply (!). If it is too hot (as with hot composting due to, for example, fresh grass clippings), the compost worms retreat to cooler zones. After the hot composting phase of a few days is over, the helpers return and process the fresh material in no time. The compost worms love freshly rotted organic material and stay in the SUPERCOMP invisibly for humans at about 20 cm below the surface.
- They overwinter in cocoons, from which young worms hatch again in spring from 6°. If you also want to compost in so-called “normal operation” in winter, it is recommended to set it up in a garage, a shed or a place close to the south wall of a house. Winter operation outdoors is certainly limited, but you can still throw away your waste. There is usually less waste in winter than in the warmer months.
- A compost pile must be ventilated in the best possible way. If this is not the case, the process comes to a standstill, takes much longer (up to 24 months) and can develop unpleasant odors due to putrefaction. The SUPERCOMP is fully vertically ventilated from bottom to top with the help of its sliding device (chimney effect).
- Compost heaps should not be moved, as the compost creatures (especially the compost worms) will immediately flee if disturbed and the composting process will have to be laboriously restarted. With a SUPERCOMP eliminates the otherwise necessary turning (= moving) and the composting process runs undisturbed.
- The environment for the living organisms should not be too moist and not too dry. A composter protects the pile from sun and rain. In extreme weather conditions under constant heat or rain, you can quickly restore the ideal conditions yourself by adding „woody” materials (if there is too much moisture) or by “watering” (if it is dry). But don't worry: this happens extremely rarely. As long as you keep providing the SUPERCOMP with fresh and moist materials, no problems are to be expected here.
In summary: A SUPERCOMP thermocomposter with its patented sliding device enables the ideal living conditions for compost organisms (1 billion organisms per cm3). This allows them to do their work at turbo speed, multiply ideally and ensure a quick harvest of nutrient-rich quality compost.
In the conventional process, the composting process takes at least 12-24 months. Here, the thermocomposter acts like a turbo, because with a SUPERCOMP you can harvest the first raw compost after just 6-8 weeks.
The ventilation with sufficient oxygen – also in the inner core of the pile – is the decisive factor for optimal heat development.
With its patented sliding device, a SUPERCOMP is fully vertically ventilated from bottom to top (chimney effect). This is the only way these temperatures are reached inside. This effect is due to the compost bacteria, which – if they are supplied with sufficient air – generate heat. Depending on the filling material, a SUPERCOMP can heat up to up to 80° after just a few days with the addition of, for example, 200 liters or more of fresh grass clippings.

The composting process does not really get going or the composting comes to a standstill more and more if the compost is too dry. The compost organisms like it rather moist and without them composting is not possible. You can recognize compost that is too dry by a cracked, crumbly structure or when ants spread. The optimal condition of the compost is like a squeezed-out sponge. Therefore, avoid locations that are in direct sunlight (alternatively plant a shrub in the area).
If the compost is too dry, simply „water” it and add a scoop of rock flour. At the same time, the sliding elements are „oiled” and the sliding speed is increased. New waste such as fresh grass and moist kitchen waste will get the process going again. You can also take a little compost soil from the harvesting chamber and add it, as it contains the microorganisms that are important for the composting process and get it going again faster.
All about worm composting
Raw compost is created after the 1st phase of composting, the “cracking” of the cells of the biogenic material, which consists of 80-90% water, the formation of valuable humic acids with dark coloration.
This also explains the volume loss of the biogenic material to raw compost by more than 60% (mature compost up to 80% volume reduction).
Raw compost can therefore be easily stored and mineralized into mature compost or – option 2 – immediately serve the plants as food, nutrient storage and “vital package”, with countless beneficial bacteria, fungi, millions of living organisms that strengthen and protect the root biogenesis of the plant consisting of millions of fungi and bacteria (e.g. via penicillin formed) and thus also promote their nutrient absorption from the soil.
In the transition zone between plant roots and soil, thousands of processes occur that we do not see, and which are not even mentioned when buying fertilizer, a little-known advantage for home composting.
Thus, raw compost is not as "beautiful" to look at as mineralized mature compost, but it is very valuable as a "vital package."
By the way: Commercially available compost is hygienized by heating, meaning that all the described life of our vital package is killed off.
Compost worms (Eisenia fetida, Tennessee Wiggler, Red Californian...) are valuable helpers in the composting process and accelerate the decomposition of your waste. The worm compost obtained through the composting process contains many times more nutrients than compost produced purely bacterially.
Earthworms can be found in every compost heap. The red worm, also known as compost worm (Eisenia fetida), can eat one and a half times its own weight every day. Under good conditions with sufficient moisture and food supply, it multiplies quickly. The earthworm ensures a crumb structure of the compost material through its activity, which allows oxygen to be better distributed in the compost.
The compost worms love freshly rotted organic material and stay in the SUPERCOMP invisibly for humans at about 20 cm below the surface. They overwinter in cocoons, from which young worms hatch again in spring from 6°.
Compost contains over 1 billion organisms/cm3 and is sanitized by the work of nature, making it a valuable fertilizer that provides your plants with many defenses (e.g. penicillin) against diseases, fungal attack and pests. The SUPERCOMP offers the ideal living conditions (complete ventilation even in the inner core of the pile) for the multiplication of compost organisms, which are responsible for processing the organic waste, for the rapid production of nutrient-rich quality compost. 1 kg of compost worms cost more in stores than the best meat from your butcher and produce expensive worm humus.
Did you know that...
- Earthworms live for three to ten years!
- The young hatch after 21 days (depending on weather conditions)!
- The earthworm is sexually mature after 60 - 90 days!
- Earthworm droppings contain enzymes that kill pathogens and thus contribute to soil health!
- Up to one million earthworms live under a soccer field!
- Earthworm droppings contain 5 x more nitrogen, 7 x more phosphorus and 11 x more potassium than the surrounding soil!
- Earthworm droppings are pH-neutral and therefore counteract soil acidification!
We have entered into a cooperation with www.wurmwelten.de, which grants our customers a 5% discount. You will receive the discount code with your order of the SUPERCOMP, which you can then redeem when purchasing the compost worms. Otherwise, you can purchase compost worms from other online providers or in specialist shops. The more worms you use, the better, but 300-500 pieces are completely sufficient for the initial inoculation.
If you set up the SUPERCOMP in the garden, you generally do not need to “seed” it, as the compost organisms will automatically “move in” into the composter within a few days through the small openings and in the area of the removal flap.
On a solid surface (asphalt, concrete), we strongly recommend an initial inoculation with 300-500 compost worms. If you regularly supply your composter with fresh waste, the population will multiply very quickly on its own and your SUPERCOMP will become a proper worm composter.
Basically, the more compost worms, the faster the decomposition process. If you already have a compost heap, you can take the worms from it inexpensively for the initial inoculation. You can also “collect” worms in nature. They like to stay under leaves, in the forest or near fresh waste.
Of course, you can also purchase compost worms in specialist shops or online.
The compost organisms responsible for a rapid composting process only work at full strength if they are supplied with
- constantly fresh food (waste)
- and sufficient air
- in an absolutely quiet environment
are supplied.
Compost organisms need a lot of peace and quiet. The compost worms flee immediately when disturbed. Nothing is moved in the SUPERCOMP, as the pile does not have to be turned. The compost regulators also do not need to be moved after the initial setting.
The continuous and complete ventilation of a SUPERCOMP due to its patented sliding device also supplies the compost worms and all other compost organisms in the inner pile core with sufficient oxygen, so that they also like to stay there and do their work. Compost worms avoid zones with a lack of air and only do their work there very slowly.
Conventional composters (mostly from the cheap segment) without special technology are nothing more than compost piles lying on the ground in a plastic cover, which often lets even less air into the pile than without a cover. The heavy compost pile, which rests on the ground, is additionally compacted by its own weight, so that ventilation is only insufficiently provided here. Further information on the problems with conventional composting can be found here.
A SUPERCOMP offers ideal living conditions for worm reproduction. The waste is broken down at turbo speed.
Composting in General
This is often correct. The reason for this is that conventional compost heaps are often incorrectly constructed and are not sufficiently turned and re-layered during operation. People prefer to avoid this annoying and "stinky" work. The ventilation here is not or only insufficiently provided and rotting nests develop, which spread unpleasant odors. The composting process also comes to a standstill and takes much longer.
Unpleasant odors due to lack of air
Many of our customers were also dissatisfied with their previous composters, where the same problems occurred. This is because - especially - inexpensive composters are usually just compost heaps "wrapped" in plastic without any technical inner workings. This also leads to a lack of air with the same problems. Therefore, manufacturers of these composters usually recommend that you turn the compost as with a classic compost heap. To do this, you have to dismantle the composter, turn the compost heap and re-layer it in the reassembled composter. You should do this regularly (at least every 14 days) to keep the composting process going.
Note: Investigations on composting plants with conventional windrow composting showed that there is a renewed lack of air just 24 hours after the turning process.
Unpleasant odors are a thing of the past
A SUPERCOMP eliminates these problems in the class of “No-Turn” composters. Due to the sliding device, the compost pile is also fully vertically ventilated in the core (chimney effect) and no unpleasant odors are produced. The composting process is thus extremely accelerated, so that you can fill in up to 3 times the amount of waste. The annoying turning is no longer necessary, as a support layer forms in the area of the device, which keeps the pile loose, so that you can easily remove your finished compost from the harvesting chamber. If the pile is too compacted – as with conventional composting – it is difficult to remove finished material under a pile weighing up to 100 kg.
Yes, composting yourself means avoiding waste, no contribution to C02 production through waste transport, no participation in the production of microplastics, saving organic waste garbage fees and producing your own fertilizer.
Composting yourself means...
Avoiding waste
Organic waste ends up neither in the residual waste nor does it have to be disposed of separately via the organic waste garbage.
Protecting the environment
No contribution to CO2 production through organic waste collection and treatment at the plant.
No participation in the production of microplastics
The sticky organic waste garbage in the organic waste garbage (plastic, residual waste) can only be partially sorted out and can be found shredded in the organic waste garbage compost.
Production of living fertilizer instead of biologically dead compost: Compost contains over 1 billion living organisms/cm3 and is hygienized by the work of nature, making it a more valuable fertilizer that provides your plants with many defenses (e.g. penicillin) against diseases, fungal attack and pests.
Save on organic waste garbage fees
Cancel your organic waste garbage with the municipality and save yourself the annual organic waste garbage fees. A few municipalities do not grant a fee reduction.
The SUPERCOMP offers the ideal living conditions (complete ventilation even in the inner core of the pile) for the multiplication of compost organisms, which are responsible for processing the organic waste, for the rapid production of nutrient-rich quality compost.

In the SUPERCOMP you will never see these helpers because you do not have to turn the pile. Only if you add, for example, a bucket of compost for an optimal start in your SUPERCOMP , you will briefly see the valuable creatures, which quickly hide away because they are shy of light and from now on work invisibly but hopefully not unthanked in your service after knowing these lines!
With a SUPERCOMP, you can of course also compost “only” kitchen waste. However, these have a high nitrogen content, which should be balanced with carbon – i.e. „woody” materials such as tree, shrub and hedge clippings, leaves, bark, straw, hay, wood shavings, sawdust, napkins or bags.
Above all, the valuable compost worms love added paper waste. 1kg of compost worms costs more than the best meat from your butcher and produces expensive worm humus.
According to waste statistics, a maximum of 600 l of kitchen waste is produced per year and family, and even the smaller SUPERCOMP processes more than 3 times that amount/year. Enough capacity also for garden waste!
When purchasing a composter, its capacity should be considered (similar to a car). This determines whether one composter is sufficient or if a second or third one is needed.
As waste is reduced by approx. SUPERCOMP is reduced by approx. 80% within 6 weeks, up to 3 times as much waste can be processed as with conventional composters, where the compost heap rests on the ground with its full weight. Of course, this also increases the purchase costs and the associated work.
Saving in the wrong place often leads to frustration, as we know from emails from new customers who are finally looking for a composter that “really” works.
Compost is not only the best additive for all soils, but also the cheapest, as it is created from kitchen and garden waste.
In the average small garden of up to 500 m2, one harvests about 0.5 m3 of compost soil annually. In the home garden, the amount is larger at 1 m3, including hedge clippings and kitchen waste. 1,000 kilograms of compost soil (about 600 liters) is equivalent to 60 buckets. In comparison, 1 sack of organic seed soil (15 kg sack) costs about EUR 6.30 in the garden market (source: guideline price from an international garden market chain). The savings through self-production can therefore amount to several EUR 100 per year.
Self-composting is therefore worthwhile, and the purchase of a composter pays for itself very quickly.
Depending on the type of waste: The finer and softer the waste, the faster it turns into compost. Bone remains or thick branches take longer but can also be composted. You can remove the first raw compost after just 6-8 weeks. Over time, the compost becomes finer and finer.
Basically, the fertilizer is removed as required - or when it is full. SUPERCOMP is full - is removed. If you do not need the compost immediately, you can store it in the garden without any problems. Only due to the complete aeration of the SUPERCOMP This is also possible in the heap core.
Fresh compost in 2-3 months
Suitable for fertilizing lawns, soil surfaces, and roots.
Fresh compost in 5 – 6 months
Can be used in the garden or vegetable garden immediately before sowing/transplanting.
Mature compost in 10 – 12 months
Can be brought into direct contact with seeds and roots.

No. In a SUPERCOMP a separate ecosystem (biocenosis) with numerous compost creatures that are responsible for the composting process forms within a short time after commissioning. To get the biocenosis going even faster, you can "inoculate" the compost with compost worms. SUPERCOMPwithcompost worms.
To maintain the optimal balance, you should occasionally check the degree of moisture inside. The optimal condition of the compost is like a squeezed-out sponge. You can recognize compost that is too dry by a cracked, crumbly structure or when ants spread. In this case, “water” with a little water and add a scoop of rock flour.
If the rotting process is too wet, however, the ventilation and thus the composting process is disturbed. Then add “woody” materials such as straw, dry grass, bark mulch, paper napkins, paper bags and rotten leaves. You can also mix in 2-3 shovels of fresh raw compost from the harvesting chamber, as this contains the microorganisms important for the composting process and gets the process going again faster.
Composting with SUPERCOMP has become as easy as possible if you pay attention to at least 3 points:
Always add woody material to the kitchen waste, e.g. leaves, branches (chopped) from the garden, sawdust. So don't put napkins in the waste paper, but compost them with the leftovers. Cover meat waste from flies, sometimes add some lime or earth.
Add water if it is dry for a long time. You can also use water to “oil” the sliding elements and thus increase the sliding speed. Empty the storage chamber regularly, leave compost residues to support the pile (if you want to compost more slowly) and also to absorb the valuable seepage water that is released during the composting process. If the rotting process is too wet, add “woody” materials such as straw, dry grass, bark mulch, paper napkins, paper bags and rotten leaves.
The following also applies here: The better the carbon-nitrogen ratio and the more diverse the waste, the better and faster the composting process.
Simple answer:
One SUPERCOMP fulfills several conditions at the same time, which together lead to a fast, odourless and also in the composting of pure materials to an optimal compost result.
As the Joanneum Research Institute has established in extensive series of tests, the vertical aeration of a SUPERCOMP enables the composting of only pure grass cuttings without the addition and mixing of other materials. The same applies to the application with leaves.
Apart from small residual amounts of branches and bones, no more plant parts are recognizable. It consists of fine crumbs (spherules) and most of the compost worms have left the pile. Only the stem and individual leaf veins can still be seen from leaves.
The base plate protects your substrate from contamination and facilitates the removal of the finished compost due to the smooth surface.
If you place the composter on paved surfaces such as terraces or concrete, the base plate is certainly recommended. If the composter is placed in the garden, you can SUPERCOMP on bricks or do without a paved base. This is also not a problem. However, make sure that the composter is set up horizontally (level the area before installation).
It is often claimed that the compost heap needs an open connection to the ground so that living organisms can get inside the heap.
From a technical point of view one can say that this is not true. The composting process also works purely bacterially, as for example in large composting plants, where the windrows are piled up on paved ground. Our laboratory tests – among other things during the composting of “exclusively” oranges – with the Joanneum Research Institute of the Graz University of Technology have also been carried out in a hall on concrete floor.
Therefore, composting with the SUPERCOMP is also possible on closed ground, terraces, etc. The base plate is waterproof and thus protects the subsoil. The smooth surface of the plate facilitates the removal of compost from the harvesting chamber.
From a holistic ecological point of view:
A connection to the ground is advantageous, but can also be replaced by introducing the “compost life”, by the user introducing, for example, 2-3 buckets of raw compost or rotted leaves with compost worms. The ecosystem also grows in this way and living creatures migrate in at night through the small gaps in the removal flap.

The correct ratio between carbon and nitrogen is important for ideal and rapid decomposition. Kitchen waste and lawn cuttings contain a lot of nitrogen, so you should always add "woody" materials such as leaves, shredded branches, sawdust, napkins or paper bags. Conversely, if the waste contains too much carbon, it is advisable to add nitrogen-rich waste.
Nitrogen-rich waste includes fruit and vegetable waste, coffee and tea grounds, potato tops, grass and lawn cuttings, bouquets and potted plants, banana and citrus fruit peels, weeds (without seeds, otherwise dried), herbs, wool, hair, manure.
Carbon-rich waste includes tree, shrub and hedge cuttings, leaves, bark, straw, hay, wood shavings, sawdust, napkins, paper bags.
The more varied the mixture of waste, the better the quality of the end product. Occasionally add a shovelful of rock flour, lime and also soil. If it is too dry, "water" it; if the compost is too damp, add "woody" material.

When the SUPERCOMP becomes full and you can no longer fill it with new waste, you should remove the finished compost from the storage chamber. If you do not need the compost straight away, you can easily store it in the garden. The compost will not lose any nutrients.
You do not need to shred kitchen waste and normal garden waste beforehand. "Strong" material such as branches, roots or oversized shrub waste should be shredded so that this waste also composts more quickly.
Protection & best appearance for many years: Order JOTUN UV-WOOD PROTECTION at the same time.
Your composter is a beautiful piece of garden furniture that is often exposed to all kinds of weather and solar radiation. We therefore recommend that you treat your composter - at least the lid - with a UV wood protection varnish.
Many of our customers ask us which product they should use. Based on previous experience, we can recommend JOTUN Demidekk Terrasslasyr in 4 selected shades (premium quality product).
JOTUN oils are used in shipbuilding, above all, due to extreme weather conditions.
Of course, the decision as to whether you want the protection remains with you.
You can also use a cheaper product (oil-based) from the hardware store.
Durability
Protection against UV fungi / UV radiation for at least 2 years (depending on the weather up to 4 years) - then repeat the process

A certain amount of moisture is required for composting - the optimum condition of the compost is similar to a squeezed sponge. However, if the compost is too wet, aeration and therefore the composting process will be disrupted. Then add "woody" materials such as straw, dry grass, bark mulch, paper napkins, paper bags and rotten leaves. You can also add 2-3 shovels of fresh raw compost from the harvest chamber, as this contains the microorganisms that are important for the composting process and gets the process going again more quickly.
The composting process does not really get going or the composting comes to a standstill more and more if the compost is too dry. The compost organisms like it rather moist and without them composting is not possible. You can recognize compost that is too dry by a cracked, crumbly structure or when ants spread. The optimal condition of the compost is like a squeezed-out sponge. Therefore, avoid locations that are in direct sunlight (alternatively plant a shrub in the area).
If the compost is too dry, simply „water” it and add a scoop of rock flour. At the same time, the sliding elements are „oiled” and the sliding speed is increased. New waste such as fresh grass and moist kitchen waste will get the process going again. You can also take a little compost soil from the harvesting chamber and add it, as it contains the microorganisms that are important for the composting process and get it going again faster.

1. MATERIALS
Glass, metal and plastics clearly do not belong in the compost heap - there is no need for an explanation.
2. ash
Coal ash is only suitable for compost to a limited extent. The ash contains heavy metals in concentrated form and the large quantities of potash increase the salt content of the compost and lead to an oversupply of the soil over the years.
3. pesticide-laden substances
Although most pesticides are broken down in the composting process, these starting products can hardly be recommended. There is too little knowledge about the combination of active substances and the dangers of the degradation products. For example, chlopyralid (this active ingredient is approved as a weedkiller in agriculture, tree nurseries and home gardens) is not broken down either in the digestive system of a cow or in the subsequent composting of cow dung and is even harmful to plants in compost.
4. VACUUM CLEANER BAGS, STREET DIRT
The contents of vacuum cleaner bags and dirt from the street or parking lot contain tire abrasion, pollutants from the air, etc. Even with these materials, you don't know what you are introducing into the compost heap ecosystem.
5. LEATHER AND TREATED WOOD
Leather and wood are often impregnated with chemicals to preserve the leather or protect the wood. These also kill the soil life in the compost and are very difficult to break down as they are designed to resist the forces of nature.
6. DOG, CAT AND BIRD droppings
The droppings of these omnivores are usually contaminated with germs and parasites, which then become a problem if there is insufficient sanitization in the compost.
7. root weeds
Field thistle, couch grass or field bindweed are very tough and often a two to three centimeter long piece of root is enough to multiply magnificently in the compost heap. Roots that have been laboriously removed from the beds should therefore be left to dry in the sun for around ten days, cut again to test whether the roots are still alive, and only then put into the composter!
8. WEED SEEDS
Weed seeds can only be destroyed in the composting process by the high temperatures of the hot rotting process. However, if the weeds are weeded before they flower, there are certainly no seeds and the young plants are much easier to remove from the bed.
9. MEAT, Sausage, BONE
may only be composted if hot rotting takes place by adding fresh waste. Never compost large pieces or whole animals! Avoid in areas where there are problems with rodents. Meat scraps should be covered to protect them from flies.
Place your SUPERCOMP in a place where it is largely protected from bad weather conditions (places with a lot of wind and in the blazing sun). As the SUPERCOMP is largely free of unpleasant odors, it can also be installed on the neighbor's border or near your kitchen.
Apart from small residual amounts of branches and bones, no more plant parts are recognizable. It consists of fine crumbs (spherules) and most of the compost worms have left the pile. Only the stem and individual leaf veins can still be seen from leaves.

The compost regulators are part of the device for supporting the heap, the heap no longer rests with its full weight on the ground and is therefore also fully aerated in the heap core. More information on the technology and function of the SUPERCOMP can be found here.
When installing, set the controls to the following position: (Fig.)

The material thrown in falls to the bottom first. After the run-in phase of approx. 6 weeks, the biowaste has composted to such an extent that it forms a cohesive mass that is supported by the device. The compost regulators are fixed after the running-in phase and cannot be pulled out by playing children, for example. You do not need to change the regulator position later. Further information on commissioning the SUPERCOMP can be found here.
