In This method large materials like broken glass pieces, stone, plastic articles etc. are first removed are first removed and remaining solid waste is dumped on ground in form of piles of 0.6 to 1 m height the width and length of pile are kept as 60%. The piles are then covered with night soil, animal dung to supply necessary organisms for biodegradation.
The temperature rises because of biological activities in the waste piles and microbial action shift to misophilic to thermophilic stage. After this pile is turned up for cooling and aeration to avoid anaerobic decomposition. The temperature of pile again rises to 75 0 C and process of turning cooling and aeration are repeated. The complete process may taker 4 to 6 weeks and finally compost is ready to use. As fertilizers
