The use of polymer sanitary piping systems incorporating recycled materials is encouraged by the regulations. To assess their service life, the CSTB has designed a test method specifically for these materials.
Regulations now require that a certain percentage of recycled materials be used in construction works. This also applies to the sanitation sector, and manufacturers have been working in recent years to increase the proportion of recycled raw materials in their products. The proportion can be up to 30% in sanitary piping systems. These products must have the same as products made with virgin materials.
Currently, manufacturers have no access to Technical Appraisals, and the materials remain noncompliant with best practices because there is no certification of their performance, including service life. The CSTB wants to work with local territories and authorities to resolve this issue.
