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 exposed to all kinds of weather and sunlight. We therefore recommend that you always treat your composter with a UV wood protection varnish, the lids 3 x on the outside!

Many of our customers ask us which product they should use. Based on our experience to date, we can recommend JOTUN Demidekk Terrasslasyr in 4 selected colors (premium quality product).

JOTUN oils are mainly used in shipbuilding due to extreme weather conditions.

What distinguishes a SUPERCOMP from a conventional composter?

SUPERCOMP Composter:

Part of the pile weight rests on the sliding device , the pile no longer rests with its full weight on the ground.

This ensures vertical ventilation of the entire pile cross-section (chimney effect), no unpleasant odors for you and your neighbors, no more tedious turning  requiered.

The compost organisms work at turbo speed, as they are optimally supplied with oxygen, heat up the compost heap, reproduce ideally and thus quickly produce nutrient-rich quality compost .

Conventional composter

The heap is surrounded by the walls of the composter, is only ventilated at the sides and lies with its full weight on the ground.

As a result, the pile compacts, and hardly lets any air through. This compaction process considerably restricts the air circulation in the heap, which slows down the composting process. The removal of finished compost is extremely laborious due to the heavy weight of the heap, as the entire mass rests on the shovel when shoveling it out.

This is why composting experts recommend turning the heap several times a year, which usually involves completely dismantling and rebuilding the composter to ensure better aeration and loosening of the material.

Protection against vermin

The composter SUPERCOMP is completely enclosed and offers all-round protection:

  • Openings and lids are sealed with gaskets
  • Supply air and exhaust air openings have close-meshed pest protection grilles
  • Effective protection against uninvited guests such as mice, rats and snails, but cockroaches must also stay outside...

Innovative composting system - how our rapid composter works with vertical aeration and the chimney effect

In the context of composting, vertical aeration ensures that:
  • oxygen reaches the entire compost heap evenly, including the core.
  • rotting processes and the formation of unpleasant odors can be avoided.
  • The microorganisms and worms have optimal conditions for the decomposition of organic substances. They work at least three times faster than when there is a lack of air without vertical aeration.
  This means that the SUPERCOMP at the same time a Rapid composter and via the heating of the microorganisms a Thermal composter. Also ideal as Worm composter, does not have to be implemented. SUPERCOMP has been recognized by the Graz University of Technology and the Joanneum Research, Graz successfully tested with the composting of kitchen waste and exclusively grass and orange waste.  Here is a brief summary of the test series.

  1. Karin-Beatrice Wenzl (Amazon customer) -

    Simply works great
    A super composter! Shipping was super fast. I treated it with outdoor wood oil when it was unassembled and then put it together. It looks great and the heat build-up inside the composter is noticeable after just a short time. As it is closed, no animals except worms and other useful insects can get in. After a garden party, I put leftover food (no meat or bones) and napkins in it and there is no smell!
    It was easy to set up and is an eye-catcher in my garden. It's also great that it processes cut grass without any problems. I would definitely buy it again.

  2. Winni -

    Very nice wooden composter, the 4 wall elements are pre-assembled, pre-drilled, simply screw together, done. Important: equipped with lid, insect protection, tight, air supply via ventilation grille and looks good. The composter has its price, but it is not just an off-the-shelf composter from the DIY store.

  3. Anonym -

    I've had my composter for 3 years now and I'm super-super happy with it!!! It sits on the patio, is very high quality, doesn't stink, works great right from the start and is perfect for a smaller household!!! My raised bed and my plants are super happy since they've had it! I am very-very satisfied and can recommend anyone to buy the composter!

  4. Martin K -

    The product arrived shortly after I ordered it. The assembly was easy and quick thanks to the excellent description and could be done on my own without any problems. The composter itself is very well made and has been doing an excellent job in my courtyard for a few weeks now. Due to the location, it is important to me that there is no unpleasant odor. This is absolutely guaranteed. I fully recommend the product and would buy it again at any time.

  5. Anonym -

    A part of the Supercomp was defective and was repaired very quickly and without any problems. That is customer service!

  6. Nina D -

    Assembly was simple and completed within 1/2 hour.

  7. J. K. -

    Side panel damaged during installation was replaced as a gesture of goodwill without any problems. Very good service!

  8. Frederick K -

    Fast delivery, very good information, personal and helpful customer service.
    After purchasing the composters, we are now looking forward to seeing how they are used!

  9. Beate F -

    Questions about the composter were answered quickly and comprehensively

  10. Hans-Dieter E -

    Fast and smooth delivery, uncomplicated assembly. It stands in the corner of our garden and looks great. I won't know if it works for at least a year.

  11. Christine -

    I have owned the Supercomp for several years and can highly recommend it. No odor and you have wonderful compost in no time.

  12. Robert S -

    I bought the large wooden composter around 5 years ago and it works like the first day. At first I thought that the wood would be a problem, that it would rot or weather quickly. With the paint on the outside and the coating on the inside, it has now lasted for 5 years. That's why I recently bought a composter from Green-Practice-Systems for my parents.

    Punctual delivery, precise, simple assembly.
    Uncomplicated complaint processing with fast subsequent delivery of a defective
    defective part

  14. Anonym -

    Received the composter on time, very easy to assemble and well described. I'm now looking forward to seeing how it works.

  15. Klaus H -

    The clarification/procurement of the paint was somewhat problematic. Instead of a general reference to the need for a coat of paint, a specific recommendation of a paint with details of the individual paint data would be helpful.

  16. Anonym -

    I was very satisfied with the quick response and handling of an inquiry by email.
    I can only recommend !!!!

  17. Franz K -

    There is no kitchen waste that cannot be disposed of here, it is a "universal composter"
    Leftovers from the vegetable garden such as kohlrabi leaves, cauliflower, carrots, radish waste, beans and peas-GRÜNZEUG, also that of pumpkin or cucumber, zucchini (is shredded with the lawn mower) lawn clippings, all this is fed into the composter. And the end product is a lot of wonderful soil enriched with earthworms!!!
    A composter that is not only very decorative in the garden, but a piece that produces effective compost!
    compost!
    We can recommend it with a clear conscience!

  18. Wendel W -

    If you follow the instructions and add a little compost accelerator, you will actually have good compost in a few months without having to turn it over every now and then. It works perfectly!

  19. Lydia Unger -

    I have had my Superkomp for many years and it looks like new. I needed a replacement lid this year and everything worked out wonderfully. Very nice contact and nice service.

  20. Klaus K -

    The wooden version is visually attractive and appealing. It can be assembled in just 1/4 hour with a little manual skill. The workmanship and quality are good. The only flaw is that the profiled wood is clearly chipped, which has a negative impact on the appearance but has no effect on the function. I can recommend the recommended wood stain from many years of experience. I cannot say anything about its functionality at the moment. We will be happy to recommend the product to others.

  21. Anonym -

    About sixteen years ago, we opted for what was then a world first, the originalSupercomp.
    The purchase price was already in the upper segment for composters at that time, but the working principle of the Supercomp described had made us curious and we have never regretted the decision; otherwise we would not have chosen this composter again now.
    The assembly of the new Supercomp (wooden version 305 L) has been considerably simplified compared to the original model and is child's play if you don't have a problem turning twenty screws in wood.
    You can't make a mistake when setting it up if you follow the instructions exactly.
    After a few weeks, the composter is in normal operation, you fill in the compost at the top and wait until the first finished compost collects at the bottom of the composter.
    With previous composters, we had never managed to produce compost as good as with the Supercomp.
    As we always had problems with vermin (including rats) with our previous composters, we decided to use the Supercomp only for garden and kitchen waste and not for food scraps.
    The Supercomp is maintenance-free, absolutely odorless and the wooden versions are an ornament to any garden.

  22. Christine -

    Quick, uncomplicated assembly. Wonderful compost after a few months. Almost odorless, so no problem in a small garden.

  23. Anonym -

    I am still very satisfied

  24. Anonym -

    This is now our 2nd Supercomp, and we are completely satisfied again. The first time we had the large 6-cornered one and it worked great. No bad smells and great compost. After the second move and being at least 15 years old, we have now replaced it with a small one, as our children have now moved out and our garden has become smaller. I really like the new model. We use the Supercomp with worms and have chosen a wooden version twice so far, as we also like the look of it. Highly recommended

  25. Anonym -

    Ordering and processing worked perfectly. A self-inflicted defect (lid not glazed) was replaced as a gesture of goodwill - exemplary! We have now been using the SuperComp for two years and are absolutely satisfied!

  26. Anonym -

    I get on very well with the Supercomp composter. My vegetable waste, together with the compostable bin liners, decomposes very well in the container over a long period of time. I regularly add leaves or grass to the waste and mix them together. Complete emptying via the flap provides good compost.

  27. Dirk C -

    Super part. I am completely satisfied. Would buy it again and again!!!

  28. Jutta V -

    Looks good and composting works very well.

  29. Anonym -

    Price performance not optimal. Workmanship and wood quality could be better. System is great, as is the look. Cover was defective after 2 years because it was covered a few times by strong winds. It is and remains the best choice visually. Compost is unbeatable. I only harvest once a year.

  30. Anonym -

    The composter works perfectly with no smell, quick composting and great compost to harvest. I put worms in it, so we have wonderful worm compost for our numerous plants. Top recommendation

  31. Anonym -

    Quick to assemble, all 4 wooden walls are pre-assembled, assembly is really very easy. The compost system works great, no odor and never had to be moved. I was able to harvest the best compost. Totally recommended!

  32. Angelica -

    Impeccable function and stability, would buy it again! Top recommendation

  33. Anonym -

    Quick and uncomplicated assembly

  34. Klaus K -

    Top article and amazingly efficient. We can only recommend this product. When setting it up, it is important that it is protected from the weather, otherwise the wooden cover will unfortunately break over time. However, we received a replacement immediately after our complaint at no extra cost. Thank you for this outstanding service.

  35. Dietlinde E -

    Gave away the composter
    I don't know anything about the web
