Das Projekt "Integration von Downstreamprozessen in Oekobilanzen" wird vom Umweltbundesamt gefördert und von Eidgenössische Technische Hochschule Zürich, Institut für Energietechnik durchgeführt. Leading Questions: How should the environmental impacts from the pollution abatement facilities be allocated to the goods thrown away? How relevant are the expenses of the infrastructure, management and the consumption of the resources compared to the direct impacts? What is the procedure if heat, electricity, iron scrap, cinder for the road construction, heavy metal recovered and salt from a waste combustion plant are offered to the public? Abstract: Up to now most LCA case studies of products take downstream processes as industrial and municipal solid waste and waste water treatment very rudimentary into consideration. For this reason there is a lack of methods and data for a reasonable consideration of downstream processes in LCA. With this project a comprehensive inventory database of the most common downstream processes in Switzerland is established. A specific inventory methodology is suggested and will be further developed in cooperation with LCA-experts of different European institutes. For an easier handling of the data a computer program, which allows to calculate the substance transfer from the techno sphere to the ecosphere for any waste with a known composition, will be available together with the final report of this project. Since the beginning of the project in November 1993, data about municipal solid waste incineration and waste water treatment plants have been compiled. Definite results will be published at the end of 1995. Complementary information: The project evaluates data concerning the flows of energy- and waste of average downstream processes (standard processes of waste management) in Switzerland. For waste with a known composition. the different flows from the techno- to the ecosphere will be determined. Particularly the consumptions of the construction and operations will be taken into account and will be attributed to the products. Primarily analyzed will be the standard processes in waste management (thermal pollution abatement facility, sewage disposal plant, deposit).
