Extra-financial performance Being a major player in the circular economy

The Group is still working on an internal solution to recover shredding waste and has introduced a unit within the technical service department to develop recovery channels. The introduction of new partnerships and the consolidation of our existing partnerships for energy recovery and mixed recovery of shredder residue remains one of the Group’s priorities. Numerous tests were carried out during the year to improve the quality of our product and to market it to potential consumers: pelletisation tests on a pilot line were carried out using shredder residue from the Bassens and Saint Pierre de Chandieu sites. The pellets can then be used as jets in cement plants; a re-shredding line for shredder residue has made it possible to obtain a product that can also be used as a jet in cement plants. After the sending of test samples, several cement groups are interested and once the analytical validation of the product has been carried out, full-scale tests will be done. Until now, shredder residue could only be used in the cement plant in the precalciner, which greatly limited their use. Significant advances in the treatment of shredder residue will contribute to a considerable improvement in the proportion sent to the recovery stream from 2021-2022.

For polyurethane foams from the processing of refrigerated large household appliances, new partnerships have been formed with cement manufacturers to use the Bernes-sur-Oise and Marignane powders and Bassens pellets in a jet. The Group responded to a call for proposals issued by the Strategic Committee for the Channel (Comité stratégique de filière – CSF) “transformation et valorisation des déchets”. In 2019, under the aegis of the French National Industry Council (Conseil national de l’industrie – CNI), the committee undertook work to develop the French channel for solid recovered fuel (SRF). This project of producing SRF from shredder residue was officially approved by the CSF on May 28, 2019 and is part of the 14 certified projects nationwide that will be supported in their development. Following long negotiations with the selected heating customer, particularly because of competition from the biomass sector, an agreement was reached and a new tripartite file (Derichebourg/Equipment supplier/Heating customer) was submitted to ADEME. If the project is successful, a boiler capable of consuming 56,000 metric tons of shredder residue per year will be built and will make a significant contribution to the recovery of the Group’s residue. Solid recovered fuels will replace the fossil fuels (coal and gas) currently used by the heating customer.
