Abstract
In the UK 30 million wet tonnes (1.2 × 106 tonnes dry solids (tds)) of sewage sludge are produced annually and its treatment and disposal costs ₤200 million per annum. Utilisation on agricultural land is the most economic disposal option for inland sewage treatment works and this route accounts for about 40% of sludge. Guidelines for sludge utilisation on land in the UK are designed to prevent contamination problems by metals, disease transmission, public nuisance and water pollution. The Council of the European Communities has introduced a Directive to be implemented in 1989 which will provide the statutory baseline for domestic guidelines in the countries of the European Community. UK guidelines and the CEC Directive are discussed in the context of potential contamination problems and the value of sludge to farmers.
