A comparative ‘best practicable environmental option’ assessment of fourteen potential sewage‐sludge treatment processes and disposal options was undertaken to support the development of Thames Water's sewage‐sludge strategy. The assessment was generic in nature and designed to provide comparative performance data on a range of potential process options forming the basis for subsequent site‐specific assessments. The study assessed: the relative technical practicability of each process option; the discounted costs of each option (including necessary environmental‐mitigation measures); environmental sustainability; and environmental nuisance. The assessment was quantitative wherever possible. The paper (a) describes the evaluation process. (b) highlights some weaknesses and strengths of the technique, and (c) demonstrates that the technique should form an essential first step in the development of any sludge treatment and disposal strategy.
