Public Law 100-688 terminated the dumping of sewage sludge and waste from industrial companies (commencing with the 270th day after November 18, 1988) under certain conditions. [11] After December 31, 1991, it was prohibited to dump any type of sewage sludge and industrial waste.

[98] [99] In 2014, a European Commission evaluation of the Sewage Sludge Directive suggested it was appropriate for its goals, and did not need revision.
Mesophilic anaerobic digestion (MAD) is also a common method for treating sludge produced at sewage treatment plants. The sludge is fed into large tanks and held for a minimum of 12 days to allow the digestion process to perform the four stages necessary to digest the sludge. These are hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring ...
