Life Cycle Assessment applied to sewage sludge treatment: state of the art, knowledge and environmental impacts assessment

Abstract

The goal of this paper is to present a state of the art of life cycle assessment of different sewage sludge treatment and to analyse the environmental impacts of different scenario of disposal and recycling routes of sewage sludge (landspreading, incineration). This study is a pre-necessary to a research project called ECODEFI (Ecodesign and development of assessment methods for innovative spreading technologies NRA program 2007-2010) conducted by Cemagref whose aim is to build a LCA simplified methodology for sewage sludge landspreading.
