SUPERCOMP Review:
Recommendations, Research, and Compost Bin Comparison

Which compost bin is right for your garden? We’ve put together an easy-to-understand summary of independent recommendations, scientific studies, and the key differences.

At a Glance

Key Findings

1

Scientifically studied

Research conducted by Graz University of Technology and studies by Joanneum Research document how the ventilation system works.

2

High-quality materials are used

In experiments, even single-material waste streams—such as grass clippings or orange peel—have been successfully composted.
3

No relocation required

The support-and-slide device relieves pressure on the compost pile. The material slides downward while air flows upward from below.
4

Recommended based on real-world testing

My gardening expert highlights the clean, low-odor composting process. The F.A.Z. Buying Guide lists SUPERCOMP in the “Innovative” category.

Scientific Documentation

Laboratory and field tests examined bacterial activity and oxygen supply. Vertical aeration is intended to prevent decay processes.

Composting Oranges and Grass Clippings

The tests show that the SUPERCOMP operates effectively even under demanding conditions: among other things, the tests were conducted using only orange waste and pure grass clippings.

Compost Bin Comparison

The Principle

How does vertical ventilation work?

In traditional, closed composters, the material rests on the bottom under its full weight. A lack of air can slow down decomposition and cause odors.

In the " SUPERCOMP ," the support-and-slide mechanism supports part of the pile. This creates a continuous chimney effect.

Air flows in from the bottom

Fresh oxygen is drawn in through the lower section.

The pile is fully aerated

The air moves vertically through the material and exits at the top.

The material slides along

Mature compost can be removed from the bottom without having to move the entire pile.

Frequently Asked Questions

FAQ on
SUPERCOMP and the Test Reports

Are there any independent tests?

Yes. SUPERCOMP has been evaluated as part of scientific research and has also been tested by specialized gardening publications, which have recommended it in comparative reviews.

The key difference is the vertical aeration system combined with the support-and-slide mechanism. This is intended to eliminate the need for re-layering and ensure a uniform supply of oxygen.

According to the manufacturer, the plastic composter is made of UV-stabilized, impact-resistant recycled polypropylene (PP). The material is weather- and frost-resistant.
