Question 17659 — waste

Summary

Mr. Bérenger Cernon draws the attention of the Minister of Health, Families, Autonomy and People with Disabilities to the potential health consequences of the use of shredded used tires in rainwater management works. The MP was alerted by the AQVIE association, based in Appoigny (Yonne), following the construction of a housing estate in which shredded used tires were used as a draining and filtering material in a rainwater recovery and infiltration basin. This practice, which tends to develop in several development operations, raises numerous questions among residents, environmental protection associations and health professionals, in particular because of the substances likely to be present in used tires or to be released over time. time. Tires indeed contain numerous chemical compounds, including metals, polycyclic aromatic hydrocarbons (PAHs), organic compounds, plasticizers and other additives, some of which are classified as being of concern for human health. In its expertise published in 2024, the National Agency for Food, Environmental and Occupational Health Safety (ANSES) emphasizes that scientific knowledge still remains insufficient to fully characterize the risks linked to certain uses of materials from used tires and recommends the continuation of research work. While infiltration basins are precisely intended to encourage the penetration of rainwater into the soil and, in certain areas, towards groundwater, the populations concerned are wondering about the potential consequences of this practice in the medium and long term, both for water quality and for human exposure. He therefore asks whether the Government considers that the scientific knowledge available today makes it possible to rule out any health risk linked to the use of shredded used tires in rainwater management works; whether epidemiological, toxicological or environmental studies complementary studies are underway or planned in order to assess the consequences of this practice on human health; if the Government intends to contact ANSES again so that it updates its expertise in the light of the most recent scientific knowledge and the multiplication of these uses and, finally, if, while awaiting consolidated scientific conclusions, it plans to recommend the application of the precautionary principle in limiting or suspending the use of used tire shreds in rainwater infiltration works.
