Take action

  • Avoid inseparable or difficult to separate composites.

  • Opt for degradable raw materials (compostable, biodegradable, soluble...).


  • Opt for non-toxic alternative materials

  • Opt for inexhaustible raw materials (biobased, fast-growing...).

  • Reuse building components.

  • Use recycled material (= processed residual flows).

  • Make sure that the lifetime of the product or material is compatible with the lifetime of the functional layer in which it is located.
