Page 1 Title: The FORWAST project: Design of future waste policies for a cleaner Europe. Authors: Jacques Villeneuve, Stéphane Vaxelaire, Bruno Lemière, Bo Weidema, Jannick Schmidt, Hans Daxbeck, Bernd Brandt, Heinz Buschmann. Abstract: In the wider context of sustainable development and environment protection, the connections between the use of natural resources, their accumulation in the economy and waste generation and management, need to be more clearly understood. Waste management policies may affect potentially all sectors. Their influence on the use of natural resources must also account for the potential recovery of these resources from stocks, the technical and economical constraints of recycling, the side effects on the by- products associated with natural resources, and at the end, the global balance of the environmental costs and benefits. The European FP6 FORWAST project intends to provide comprehensive and validated data on the material flows, stocks and environmental pressures coming from the different sectors of the life cycle of resources to waste. Certain stocks are particularly relevant to recycling in the construction industry. The method implemented is based on an environmentally extended, physical, quasi- dynamic input-output model. This model combined with a robust method of Material Flow Analysis guides the mining of new data that take place as a combination of “in- depth” studies in selected countries where high-quality statistics are available, and an EU-wide effort aimed at consolidating and calibrating different statistical and technical data sources.

 Title: The FORWAST project: Design of future waste policies for a cleaner Europe.  Authors: Jacques Villeneuve, Stéphane Vaxelaire, Bruno Lemière, Bo Weidema, Jannick Schmidt, Hans Daxbeck, Bernd Brandt, Heinz Buschmann.   Abstract: In the wider context of sustainable development and environment protection, the connections between the use of natural resources, their accumulation in the economy and waste generation and management, need to be more clearly understood. Waste management policies may affect potentially all sectors. Their influence on the use of natural resources must also account for the potential recovery of these resources from stocks, the technical and economical constraints of recycling, the side effects on the by-products associated with natural resources, and at the end, the global balance of the environmental costs and benefits. The European FP6 FORWAST project intends to provide comprehensive and validated data on the material flows, stocks and environmental pressures coming from the different sectors of the life cycle of resources to waste. Certain stocks are particularly relevant to recycling in the construction industry. The method implemented is based on an environmentally extended, physical, quasi-dynamic input-output model. This model combined with a robust method of Material Flow Analysis guides the mining of new data that take place as a combination of “in-depth” studies in selected countries where high-quality statistics are available, and an EU-wide effort aimed at consolidating and calibrating different statistical and technical data sources. The model will be applied to historical time series of resource inflows into the economy, and calibrated to known quantities of waste generation, a core question being the estimation of coefficients for lifetime stocks, for the different materials (sand/gravel, wood, metals, paper, etc.) and the dynamic interpretation of the causes of stock variations (accumulation versus waste generation or dispersive losses). The policy-relevance of the project is strengthened by the definition of 25 years horizon scenarios of waste generation, combined with technological options for waste prevention and recycling. The waste with the highest stakes with respect to environmental pressure reduction will be identified through simulation. This paper presents the first results of the project: the principles and the structure of the model and the progress/difficulties of the data mining. It highlights the necessary disaggregations of economic activities for accounting for waste flows and the substances taken into account for calculating environmental impacts.    Page 1
