Basically: Composting only one type of material is ranged somewhere between “difficult” and “impossible”. Tests had been done where, for example, when composting surplus oranges in Sicily (Italy) by windrow composting, success was only achieved after adding 2/3 of other organic waste to the oranges.
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.
