Waste will be the raw material of the 21st century: this was Jean-Luc Petithuguenin's vision when he founded the Paprec group 30 years ago. Faced with the challenges of climate change, which require us to accelerate the decarbonization of our economy, and with the imperatives of sovereignty following the recent crises, switching to a circular economy model has become an obvious choice. This model is indeed virtuous, as it respects planetary limits and provides a relevant, local response to our dependence on fossil fuels, and gives us back control over our supplies of raw materials. Today, waste is unquestionably an issue of industrial and energy sovereignty in France and Europe: recycling it produces new raw materials that avoid the extraction of primary raw materials, organic waste can be recycled into biofertilizers that replace nitrogen fertilizers, and non-recyclable waste can be used to produce local, low-carbon energy. The development of recycling chains requires partnerships and industrial cooperation between players in the sector in a number of areas: development of eco-design of products, incorporation of raw materials from recycling into industrial processes, improved collection and sorting performance, sustainable and innovative recycling chains.Paprec, France's leading recycler and producer of low-carbon energy, will illustrate these issues through concrete examples of application and the sharing of best practices.
