A consumption approach to wastes from economic activities

Abstract : In a context of waste management policies aimed at promoting waste prevention and recycling and, conversely, reducing waste landfilling, this study investigates how waste is generated and treated in a consumption perspective. A Waste Input-Output Analysis is implemented that considers 14 waste fractions and four waste management techniques. Input-Output Tables extended to wastes are initially compiled for the year 2008 considering France and five of its main import suppliers, and further completed with data on waste treatment. Wastes from economic activities are accordingly reallocated to the product categories of household consumption that induce their production. In particular, considering five waste categories (dry recyclable wastes, mixed wastes, mineral wastes, organic wastes, and total wastes) as an aggregation of the 14 waste fractions studied, the ten product categories with the highest contribution account for 64-86% of the total generation of wastes. Waste intensity and volume of expenses are analyzed as the drivers for the amounts of wastes induced by each product category. Similarly, the products responsible for the largest amounts of waste landfilling and incineration without energy recovery, i.e. the management techniques at the bottom of the "waste management hierarchy", are identified. Moreover, this study highlights the relative importance of waste produced abroad as compared to that produced in France, regarding the total amount of waste induced by French household consumption. The sensitivity of results to the modeling of import production is subsequently discussed. Finally, the potential perspectives for this type of consumption approach are considered with respect to its utility and current limitations in a context of waste policy planning, and more particularly regarding the way waste policy targets are set.
