JOANNEUM RESEARCH conducted empirical studies for 12 weeks on the practicability and efficiency of the individual SUPERCOMP compost systems.

Significant innovative components in the system are the sliding surfaces which slow the downwards movements, leading to a continuous rotting process with an optimized vertical ventilation. The physical basis for this are the different frictional forces between the mature compost and immature rotting material, which, via the formation of support lines, lead to the stabilizing of the rotting material, thus enabling a continuous process. The selected surfaces and angles of inclination of the sliding surfaces lead to the building of support lines in the rotting material within the first 6 weeks.

The Joanneum Research Institute of the University of Technology of Graz (Austria) led empirical studies on the practicability and efficiency of the individual SUPERCOMP compost systems. The composting of organic waste by SUPERCOMP resulted in plant-tolerated compost after a rotting duration of 12 weeks, a volume reduction of 80% and a reduction of the organic components of 64%.

Will “only” one composter in my garden be enough?

When purchasing a composter, performance should be considered (similar to when, for example, purchasing a car), as this is what decides whether only one composter is enough, or if a second or a third one are needed.

Since a SUPERCOMP reduces waste by 80% within 6 weeks, up to 3x as much waste can be processed than in traditional composting, where the compost heap is laying on the ground with full weight. This of course, also increases the cost and work involved. Saving money in the wrong place then often leads to frustration, as we know it from emails from new customers who are finally looking for a composter that “really” works.

Determine your required SUPERCOMP composting performance with a simple formula:
Number of 10-litre-pails fully filled with organic per week x 52 weeks = Required SUPERCOMP liters

Example of required composting performance in an average household with a garden:
ø 3 x 10l-bucket / week x 52 weeks = 1,560 litres or 156 buckets

The SUPERCOMP year Transcript:
• Thermo Wood Composter 650 L volume: 5,400 litres / year = 540 buckets
• Thermo Wood Composter 305 L volume: 2,500 litres / year = 250 buckets
• Recycling PP Composter 350 L volume: 2,800 litres / year = 280 buckets

Note: This formula applies to waste in normal domestic setting and applies to the SUPERCOMP (not other composters).

About the price
Composter come for free in the form of compost heaps. Cheap composters are usually barrels coated in plastic without internal technology (= enveloped compost heap) and may have the problems described on Professional composters with internal technology are more than just “tons”, have many more advantages and are, in comparison, also more expensive. SUPERCOMP composters are rapid composters with the 3-benefits-technology, and process organic waste up to 3 times faster than compost piles resting on the ground. For this reason, a SUPERCOMP (305/350 liters) is usually enough for an average household with a garden size of up to 500 m2. Many of our customers are surprised about how much waste you can fill in a SUPERCOMP and how quickly the piles reduce.

Does your compost pile provide sufficient comfort to its inhabitants?

The compost creatures are responsible for the rapid composting process, only working at full strength if they are provided with

  • constantly fresh food (waste)
  • and sufficient air
  • in an absolutely quiet environment

Compost creatures need a lot of rest. The compost worms flee immediately when disturbed. In SUPERCOMP nothing is moved, because the pile doesn’t need to be turned or moved around. The compost regulators also don’t have to be moved after their initial set-up.

The continuous and complete ventilation of SUPERCOMP is possible due to its patented support system, supplying the compost worms and all other living beings, and also the compost heap’s innermost core, with sufficient oxygen, making it possible for the compost creatures to perform their work even there. Compost worms avoid zones that have a lack of air and do their work there very slowly.

Conventional composter (mostly from the low-price segment) without special technology are nothing more than compost piles lying on the ground in a plastic sheath, often letting even less air into the pile as they would without a shell. The heavy and burdensome compost pile, which is on the ground, additionally compacted by its own weight, only provides scarce and inadequate ventilation. For more information about the problems with conventional composting can be found here.

A SUPERCOMP provides ideal living condition for worm multiplication. The waste is decomposed incredibly fast.


In a test series done by the Institute of Process Engineering of the University of Technology of Graz in which only oranges were composted in a SUPERCOMP. This test can therefore be considered as difficult, since the decomposition of oranges lasts much longer than other types of waste, and due to their high nitrogen content, other forms of bio waste must also be mixed in to even be able to compost the oranges.
