METHOD AND APPARATUS FOR MAKING ORGANIC SUBSTANCE, ESPECIALLY WASTE SUBSTANCE INTO FERTILIZER

摘要

A process is intended for composting organic materials (biodegradation material), in particular waste, for example domestic waste or waste which resembles domestic waste. The biodegradation material is introduced into a sealed container and subjected to microbial degradation while passing in oxygen. A mixture of pure oxygen and waste air is furthermore added to the biodegradation material. To improve such a process, the CO2 in the waste air is returned to the biodegradation material. The water in the waste air which emanates from the biodegradation material is removed.
