✦ Synopsis

HS-OFMSW

Experiments carried out to obtain data for a pre-k liminary design of an anaerobic digestion plant treating the organic wastes coming from a large MS-OFMSW food market are described. Four hydraulic retention times (8, 12, 14 and 20 days) were tested in OFMSW 3-litre laboratory digesters. The methane fields were high (around 0"478 m 3 CH4/kg VS added). Q Kinetic analysis, using a first-order model, resulted S in a kinetic constant of 3.1 day-~ and an ultimate methane yield of 0.489 CH4/kg VS added. The S o biodegradability of the soluble and non-soluble fractions of the Volatile Solids (VS) is discussed.
