Abstract

Composting is a controlled thermophilic aerobic decomposition of organic solid wastes. The main part of the Dano-System composting plant is the biostabiliser. The biostabiliser was fed with 28 to 81 t of municipal wastes during 24 h. The temperature of composting wastes (28–56 °C) depended on the time of sampling and actual loading of the biostabiliser. Fresh compost from the biostabiliser was put in piles for a period of one to some months to obtain a marketable product. The samples of composting material were taken in 1998–1999 from the middle and the end part of the biostabiliser. Additionally, compost from the piles was sampled. A prototype isothermal calorimeter was used to determine the rate of heat production (RHP) of composting material. The method of closed jars for determining CO2 production was used. The temperature of composting material in the biostabiliser was measured twice every day in 1998 and 1999. A few times the temperature was measured over a period of 24 h. The temperature inside about 2 m high piles was measured at the depth of 1 m.
