Comparison SUPERCOMP vs. a conventional compost bin

Why conventional composters reach their limits – and how SUPERCOMP solves the problem.

SUPERCOMP Thermocomposter

With sliding device
  • Base layer: Pile is relieved by the sliding device – no longer rests on the ground with its full weight.
  • Aeration Vertical air circulation (chimney effect) ensures oxygen throughout the compost heap
  • Odour formation: No bad odours thanks to optimal aeration
  • Compost quality: Nutrient-rich compost through turbo composting
  • Turning the pile: No laborious turning required

Conventional composters

Without sliding device
  • Ground support: the pile is enclosed by walls and rests with its full weight on the ground.
  • Aeration: Compaction restricts airflow – little oxygen, no air circulation, and the composting process slows down
  • Odour formation:Rotting and foul smells due to lack of air
  • Compost quality: Slow process with risk of rotting & unpleasant odors
  • Turning the pile: Several per year – requires full dismantling of the bin

02.

Start the first filling

Start with mulch, straw or old compost.
Start with approx. 50 L of structural material (e.g. mulch or old compost). Then add your organic waste daily. After 2 months, remove the starting material from the removal flap and put it back in at the top – SUPERCOMP is activated.

Composting automatically

03.

Composting is running – completely automatically

Simply throw in at the top, remove at the bottom.
No turning of the pile necessary. Thanks to the chimney effect created by the sliding device, the compost pile remains loose, aerated and odorless. Meat scraps, citrus fruits & peels can also be composted without any problems. Composting with a modern plastic composter can be that easy!

What our customers say about the
SUPERCOMP say

Real experiences, real results – our customers are so enthusiastic about composting with the SUPERCOMP.

Michael K., St. Ruprecht

All composters had to be constantly turned and the odor was correspondingly bad, and mold also tended to form in the composters. Since we started using the Superkomp, we have been able to get by with a comparatively...

small composter, where nothing smells, doesn't need to be turned and the compost is metabolized very quickly. Citrus fruits and even meat scraps (we didn't dare throw them on the compost before) are also composted. We were initially concerned about the size, as I said, the composter looked tiny next to the 3 previous ones, but the composter more than makes up for this with its rapid processing of the compost material. It is now usually 3/4 full, but we hardly ever put grass cuttings into the composter. It is important to have a level and firm base, I have made a U-shaped foundation here in a sand bed (which I dug out about 15 cm deep beforehand) with some clinker bricks. This keeps the composter straight and stable. We would buy the composter again at any time, overall verdict: unbeatable!

Familie Sacher

We were looking for a composter that works well, doesn't smell and looks good, as it is clearly visible in our yard. After the first 10 months of use and the first time we took it out...

we are very satisfied. The workmanship on the lid and removal flap was not optimal, but customer service was very friendly, accommodating, prompt and uncomplicated in delivering new parts. The compost is dark and rich, removal is child's play, there's nothing to do. Bio in at the top, compost out at the bottom. No odors at all, even when the sun is shining directly on the Supercomp and you're standing next to it. We were a little hesitant before we bought it because the price seemed quite high, but we think the Supercomp is absolutely worth the price! If you are looking for a composter with which you have zero work, which you can set up practically next to the balcony or garden table and which delivers great compost, then this is the one for you! By the way, we only throw in fresh organic waste, no processed waste, nothing cooked and no meat, bone or sausage waste to avoid attracting uninvited guests. We always cook fresh and there is a lot of organic waste.

Heinz H.

We have been using your two Supercomp for about 2 months. The composting works excellently. The compost smells fresh and aromatic. However, we have not yet removed any compost. Through...

The compost already looks completely "finished" at the bottom openings. We estimate that the two Supercomp will replace Supercomp four conventional compost bins. With the Supercomps, composting is fun again.

Family A., Weyregg am Attersee

We were not satisfied with the previous products. The ventilation system simply works better than we had hoped. All the promises of being able to remove compost after 4 weeks, no shoveling necessary and NO more unpleasant odors have been 100% fulfilled...

However, we paid too little attention to a stable and absolutely horizontal base when setting up the SUPERCOMP . So it became necessary - we have the plastic model - to completely empty the SUPERCOMP and create a stable base. Mr. Schmidl, thank you for your prompt advice, we can recommend the SUPERCOMP unconditionally! Best regards from the Salzkammergut, Family A.

Hans-Dieter E., Germany

Admittedly, the initial cost was considerably higher than for a normal composter, but in retrospect we can say that it was 100% worth it. With the "Supercompwe were able to effortlessly and quickly...

It produces excellent compost without any tedious turning and, above all, without any unpleasant odors! In our opinion, the "Supercompis the only device that deserves to be called a composter.

Feodor H., Hardegseen

We use it to compost all garden waste, including a lot of grass cuttings and all compostable kitchen waste. The composting process is completed after approx. 8-9 weeks. No odor nuisance, excellent composting results...

fermented soil as the end product. The garbage cans are located in D-37181 Hardegsen, which is in the district of Northeim. Subsequent procurement of replacement parts (storm damage caused by hurricane Friederike) by the manufacturer was also exemplary. I can recommend the company's products at any time.

Friedrich K., Switzerland

We have been "harvesting" good, black compost again and again for 4 months, hoping that the seeds in it have lost their germination capacity due to the process heat. But we'll see next spring, which we've been waiting for at breakneck speed for the last two days...

is approaching. I am thoroughly satisfied with your product!

Renate R.

The spare part was delivered to my home free of charge within 2 days. Very friendly and competent service. The composter is beautifully made, easy to assemble and a beautiful sight in the garden.

Verona D., Leipzig

It doesn't get any better than that! Great! Thank you very much!

Reference certificates

The SUPERCOMP was successfully tested by the Technical University of Graz and Joanneum Research for composting kitchen waste as well as exclusively grass and oranges.

"First and foremost, this test was successful due to the vertical ventilation of the composter. This creates the best conditions for the microorganisms."

Frequently Asked Questions about the
SUPERCOMP Composter

Here you will find answers to the most important questions about setup, use, composting and everything you should know before buying.

Does the composter smell unpleasant?

No – not with the SUPERCOMP.
Odors are usually caused by poorly ventilated compost, as is often the case with conventional composters. If the regular turning of the pile is neglected or the material is compacted, it leads to rotting and unpleasant odors. The SUPERCOMP prevents exactly that: The integrated sliding device ensures vertical ventilation throughout the pile – even in the core (chimney effect). This keeps the material loose, well ventilated and prevents rotting.

No – the SUPERCOMP is fully protected and remains free of unwanted guests. Thanks to its completely closed design, finely perforated ventilation grilles and additional sealing tapes on the lid, door and ventilation openings, pests such as rats, mice, snails and insects have no chance. In addition, the optimal ventilation (chimney effect) prevents rotting – and thus also odors that could attract pests. The SUPERCOMP remains clean, hygienic and reliably protected.

That depends on the type of waste:
The finer and softer the material, the faster it decomposes. Kitchen waste or soft plant material composts particularly quickly – while bones or thick branches take significantly longer, but can still be recycled.

Thanks to the sophisticated ventilation right into the core of the pile (chimney effect), the composting process in the SUPERCOMP starts immediately – without any turning of the pile necessary.

  • First raw compost: after approx. 6–8 weeks
  • Fresh compost: after 2–3 months – ideal for lawns, soil surfaces or root fertilization
  • Semi-ripe compost: after 5–6 months – for preparing beds before sowing or transplanting
  • Mature compost: after 10–12 months – can come into direct contact with seeds and roots

 

If you do not use the finished compost immediately, you can easily store it in the garden in the meantime.

The ideal location for the SUPERCOMP is partially shaded to shady, with some air circulation. Direct sun is not a problem – the UV-resistant plastic and good insulation protect the material –, but the compost dries out faster in strong sunlight. In this case, it should be moistened occasionally.

It is also important to have a level, easily accessible location so that filling and removing the compost is convenient – for example, directly at the house or near the garden entrance.

Thanks to its closed and odorless design, the SUPERCOMP is also ideal for use in densely populated residential areas.

No! Thanks to the integrated support and sliding device, the compost pile is vertically ventilated down to its core (chimney effect). This keeps the material loose and well ventilated – without any turning of the pile necessary.

This not only saves work, but also speeds up the composting process considerably. You can fill in up to three times more waste and conveniently remove the finished compost via the harvesting chamber – without shoveling, digging or turning of the pile necessary.
