WASAN: A Methodology for Analysing Waste Minimisation

This paper presents a new methodology called Waste And Source-matter ANalyses (WASAN) which helps a group to analyse waste-production and build actions to minimise avoidable waste. Designed for Licencees of nuclear facilities as Health and Safety Executive (HSE) Guidance on what constitutes good practice, WASAN uses lessons from Systems Thinking, Waste Management Hierarchy, Hazard Operability (HAZOP) Studies, As Low As Reasonably Practicable (ALARP), simulation modelling and sensitivity analysis. These lessons are used to support groups when developing plans to reduce avoidable waste production. We report on the development of WASAN and its use in three workshops. This paper reports progress on the development of waste management guidance for the HSE and does not currently represent its final regulatory view.
