Composting of anaerobic sludge: An economically feasible element of a sustainable sewage sludge management

► We conduct composting of anaerobic sludge in real conditions at almost full-scale. ► We examine composting with mixtures of sludge to bulk agent ratios of up to 6.4:1. ► We examine the economic feasibility of such sludge management. ► Compared to incineration composting is more feasible sludge management.
