Providing practical information on which to base decisions about incineration for waste disposal, this is a reference handbook for pollution control engineers and managers. Among the various processes available for destroying and detoxifying wastes, incineration is often a practical option for disposing of combustible solids, semi-solids, sludges, concentrated liquid wastes and gases. It reduces, and often eliminates, environmental risks, and in some cases yields recoverable energy. The Environmental Protection Act 1990 applies regulatory systems to over 30,000 industrial processes, of which the operators are required to "render harmless" all releases. Much relevant information has been compiled in the USA, where regulatory legislation began to bite earlier than in the UK, and this handbook is an example of such a source.
