Pyrolysis

Pyrolysis is the decomposition of organic matter at elevated temperatures (300 and 1300 °C) in the absence of oxygen at atmospheric pressures. The useful products generated are a charcoal-like biochar solid product, a bio-oil formed from ‘condensable’ volatile substances and ‘non-condensable’ gases which may include both carbon dioxide and methane.

Phosphorus recovery by sludge acidification and dewatering

A pilot-scale Danish study of phosphorus extraction from acidified anaerobic and aerobic sludge samples has revealed removal to be more effective from anaerobic sludges, even though the digested sludge alkalinity increases the total acid demand.
