Calculating the pre-consumer waste footprint: a screening study of 10 selected products
(English)Manuscript (preprint) (Other academic)
Knowledge aboutthe total waste generated by the production of consumer goods canhelpraise awareness among policy-makers, producers and consumers of thebenefits of closing loops in a future circular economy and avoiding unnecessary production and production steps and associated generation of large amounts of waste.In strict life cycle assessment (LCA) practice, information on waste outputs fromintermediate industrial processes of material and energy transformation is only translatedinto and declared aspotential environmental impacts, whichare oftennot even shown in the final results. In this study, a procedure to extract available intermediate data and perform a systematic pre-consumer waste footprint analysiswas developed. The pre-consumer waste footprint concept was tested to analyse 10 generic products, whichprovided some interesting results for the different product categories and identifieda number of challenges that need to be resolvedin development of the waste footprint concept. These challenges include standardiseddata declaration on waste in LCA,with a separationintowaste categories illustratingthe implicit environmental and scale of significance of waste types and quantities(e.g. hazardous waste,inertwaste, waste for recycling/incineration)and establishment ofa common definitionof waste throughoutsectors and nations.
