Provisions |
Recycling processes are always specific to a product or material. Thus the provisions in EN 15804 should be referred to. This aspect is likely to be predefined in every national EPD programme, and may be adopted within the context of the conducted LCA study. | |||||||

Guidance |
Current practice should be used for scenarios. Material-specific models for waste treatment may be relevant for particular materials, to take account of emissions or the amount of energy recovery. Also, public and commercial background LCA databases provide material-specific datasets that may be used.The default scenario should be based on actual achievement in current waste management practice, and not on what might happen in 50 years’ time. It is important to use average recovery rates based on the mix of recovery techniques used and not the best case, although additional scenarios can be used to illustrate the effect of the different waste management options that are available. Geographically, the default scenario may vary: for example, a waste may be more commonly landfilled in one Member State, used for energy recovery in another Member State, and recycled in another Member State. It may be advisable to use product-specific end-of-life datasets. | |||||||
