Comparison of co-digestion performance of two differently collected organic fractions of municipal solid waste with sewage sludges

This paper deals with the comparison of the co‐digestion performances of two digesters treating organic fractions of municipal solid wastes (MSW) and primary and secondary sewage sludges mixed at various ratios between 0 to 100% TS basis. The organic fractions treated differ in their collection procedures, which influence the chemical characteristics of the substrates and then the process performance. These differences and their influence on the anaerobic digestion process are emphasized throughout the paper so as to assist public sector managers in their choise of treatment method from the harvesting procedure to the final disposal technology of MSW.
