Alternatives, other than incineration, to the sea disposal of sludge are discussed. Land reclamation could use 20 per cent nationally, with concentrated utilization in coal mining areas. Forestry had potential for 12 cent and co-disposal with domestic waste on landfills, currently 18 per cent, might increase. Controlled composting by forced aeration and windrowing were under investigation at Wye College with the former method appearing more effective. A soil from sludge project was on trial at Horsham. Resource recovery techniques such as the extraction of proteins, vitamins and phosphorus, or oil from pyrolysis were not at an advanced stage. Given sufficient education, the public might be prepared to accept several disposal methods.
