Flexible sheets for waterproofing — design for recycling - bitumen waterproofing sheets

Scope

Throughout the entire lifecycle of bitumen waterproofing sheets, from production and construction to service life and final disposal, waste generation will occur.

This document provides guidance on design for recycling and methods to calculate recycled content from pre-consumer material and post-consumer material as it is used in the production of new products. These new products may be bituminous sheets, other construction bituminous products or other bituminous products (e.g. primers).

NOTE This document is applicable for similar products as construction sheets or membranes consisting of bitumen, polymers or plastic components such as: geosynthetic membranes, membranes for road constructions and bridge decks, protection membranes.
