Abstract


The present study was undertaken to analyse the chemical properties of aerobic compost from abattoir and poultry slaughter waste. Various abattoir waste materials like rumen contents, abattoir sewage sludge, poultry feathers and commercially available coir pith were preprocessed and separately analysed for their physico-chemical properties. Based on the analysis of physico-chemical properties of raw materials, five different combinations were selected for aerobic composting viz. sludge and coir pith (1:1); rumen contents alone (100); rumen contents and poultry feathers (1:1); rumen contents and sludge (1:1); rumen contents, sludge and coir pith (1:1:0.5).The selected combinations were subjected for aerobic composting for a period of 60 days in biobins. Chemical properties like organic carbon, total nitrogen, carbon to nitrogen ratio (C: N ratio), total phosphorus and total potassium before and after composting were analysed. There was a significant (p<0.05) increase in total nitrogen, total phosphorus and total potassium content and significant (p<0.05) decrease in C: N ratio and organic carbon content after composting.
