Method for taking into account the end-of-life when performing life cycle analysis (LCA) "product". State of the art

Summary

During the life cycle of a product, waste may be generated at each stage and the product itself becomes waste at the end of its life. In LCAs, assessing the environmental impacts and benefits associated with these "end-of-life" stages can raise a number of difficulties. Among the main ones are the multifunctionality of waste treatment processes, consideration of the carbon cycle, the time scale of emissions and the allocation of process emissions to a specific type of waste. In order to better analyse and take account of these difficulties, the document provides clear, didactic fact sheets containing case studies (sector fact sheets, method fact sheets and database fact sheet) providing LCA practitioners with the information they need: key issues relating to a particular treatment sector, the approach to be used to calculate the end-of-life of a product, etc.
