Résumé :

The article presents a classification and comparison of Decentralised Organic Resource Treatments(DORTs), a term that refers to relatively small-scale biowaste treatments that have emerged as apromising alternative to centralised, industrial facilities. Despite growing interest from policy makersand waste professionals, accessible and coherent information on different decentralised treatments iscurrently not available. To overcome this gap in the literature, we propose an Extended Material FlowAnalysis (EMFA) based on a review of the literature and expert interviews. In addition to flows of inputsand outputs, the EMFA also accounts on the economic, normative, and technical aspects of each treatment.The final EMFA database includes seven broad types of DORTs (composting, anaerobic digestion,dehydration, lactic acid fermentation, mulching, vermicomposting and animal valorisation) that arefurther divided into 18 representative models. The most relevant and comparable variables are summarisedin form of synthetic flow diagrams.
