Tri des déchets alimentaires dans le Grand Paris - État des lieux et perspectives d’une filière en développement
The study gives an overview of practices and the deployment dynamics throughout the metropolis. The levers for action and ways for optimising presented here were identified in collaboration with the waste management departments of the 12 territories of Grand Paris Metropolis, based on responses to a questionnaire and supplementary interviews.
In metropolitan areas, food waste amounts to 540,000 tons, that is 77 kg per capita per year, which is produced by consumption in and outside homes. While this has great exploitation potential for recovery through methanation or being composted, the capture rate is around 3.5% of the estimated total amount, i.e. approximately 19,000 tons. This waste also constitutes 25% of the contents of residual household waste, which affects the process of incineration. There is a very wide margin for improvement.
Two years after the law came into force, Metropolitan areas are continuing to put in place schemes for sorting waste and/or treating it at source in order to improve the efficiency of recycling procedures. By 2025, 2,100 voluntary waste disposal points were already operational in the municipalities who opted for this solution. Door-to-door collection is developing in other municipalities, as are complementary local composting possibilities. Apart from the diverse situations, examination of the initial data shows a general steady rise in the tonnage collected, closely linked to the scale of the schemes and awareness-raising action carried out. The opening of the anaerobic digester plant in Gennevilliers in 2026, with a treatment capacity of 50,000 tons per year, will be a significant landmark in the local treatment of food waste.
