Cascade use

Cascade use describes the step-by-step use of raw materials to extend their life cycle. In this process, the raw materials are used in several utilisation cycles, with the requirements decreasing with each cycle. For example, wood residues can be reused in furniture production or as paper after their first use as construction timber. Subsequently, they can serve as fuel in biomass power plants before finally being returned to the biological cycle through final thermal utilisation.

Cascade use offers numerous advantages. The step-by-step reuse of raw materials reduces the need for new resources and thus minimises the environmental impact. In addition, companies can save costs by using recycled raw materials.

Despite the numerous advantages offered by cascade use, there are also challenges to overcome. Effective implementation requires close cooperation between the different actors along the value chain, from raw material extraction to production and disposal. The legal framework must also be adapted to promote cascade use.
