Compost characteristics from sewage sludge and organic fraction of municipal solid waste

Composting of sewage sludge and organic fraction of municipal solid waste c an enhance its quality and suitability for agricultural use. The aim of thi s work is to present the physicochemical characteristics of the compost pro duced from dewatered, anaerobically stabilized primary sewage sludge (DASPS S) and organic fraction of municipal solid waste (OFMSW). The final results indicate a good soil conditioning for agricultural use. The co-composting products are found to have higher concentration of total humics (9.50 %), a nd organic matter (38.23 %) than the sewage sludge (3.50% and 32.81 %, resp ectively). Also the heavy metals' concentration in the final products are o bserved to be in lower concentration than in the sewage sludge compost.
