Comparison SUPERCOMP vs. a conventional compost bin

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

SUPERCOMP
Compost Bin

With sliding device
Supercomp animation comparison vertical ventilation
  • 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

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 lower openings, the compost already looks "finished". We assume that we can replace about 4 conventional composting beds with the two Supercomp . The Supercomps make composting really 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 purchase costs were considerably higher than for a normal composter, but in hindsight we can say that the purchase was 100% worth it. With the "Supercomp" we have for the first time effortlessly and in a short time...

produces excellent compost without laborious turning and, above all, without any unpleasant odours! In our opinion, the "Supercomp" is the only thing 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."
