Abstract

Charicteristics of piggery waste and treatment processing sludges for reuse were investigated. If it was thoroughly regulated in disinfectants, antibiotic substances and heavy metals, raw piggery waste can be gratified in criteria for fermentative compost (liquid) for flowers cultivation. Also, Because it is satisfied with various criteria of heavy metals and fertilizer contents for reuse except water content, primary pre-treatment sludge is very good material for composting. If provated goods on heavy metals are used in coagulation & dewatering process, coagulation & dewatering sludges are suitable for criteria of special waste regulation and by-product compost. This study proves that, if they are accomplished with suitable composting and mature process, piggery waste and processing sludges are free from microbiological problems as well as criteria of composting.
