摘要: The aim of this study is to characterize different types source selected organic fraction municipal solid waste (SS-OFMSW) in order optimize the upgrade a sewage sludge anaerobic digestion unit by codigestion. Various SS-OFMSW samples were collected from canteens, supermarkets, restaurants, households, fruit–vegetable markets and bakery shops. substrates characterization was carried out getting traditional chemical–physical parameters, performing elemental analysis measuring fundamental macromolecular compounds such as carbohydrates, proteins, lipids volatile fatty acids. Biochemical methane potential (BMP) tests conducted at mesophilic temperature both on single codigestion regime with mixing ratios. maximum yield observed for restaurant (675 NmlCH4/gVS) canteens wastes (571 645 NmlCH4/gVS). best BMP test has highlighted an increase 47% production respect digestion.
