The forced aeration static pile composting system was used to compost mixtures of domestic refuse and sewage sludge. Several different control methods have been evaluated over the past four years from simple, low cost fixed rate aeration timers to microcomputer based systems. Their relative merits are considered. In a compost pile using temperature feedback control the number of Escherichia coli were reduced from 107 org./g to less than 102 org./g. within 16 days. Faecal streptococci were reduced from 107 to less than 102 org./g within 30 days. The process consistently produced a good quality sanitised material under a range of control regimes.
