Anaerobic treatment of sewage sludge and grease trap sludge in continuous co-digestion

by

Neczaj E., Bien J., Grosser A., Worwag G. and Kacprzak M.

Issue 2

General

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency...

Application of sludge, organic solid wastes and yard trimmings in aerobic compost piles

by

Chazirakis P., Giannis A., Gidarakos E., Wang J.-Y. and Stegmann R.

Issue 4

General

The effects of different mixture ratios of sewage sludge (SS), organic fraction of municipal solid waste (OFMSW) and yard trimmings (YT) on the performance of composting process were investigated in this study. The high water content and the proper carbon/nitrogen ratio make sludge ideal for this...
