Recyclability and recovery potential

The recyclability and recovery potential of the reference configuration and HMI are calcu-
lated using the end of life scenario given by IEC/TR 62635, Annex D.3, which is repre-
sentative for Europe. The dismantling of single recyclable materials is considered, which
result in a higher recyclability potential. After recycling, the materials are assumed to go
through energy recovery and finally, sent for residue disposal. Table 6 shows the recycla-
bility and recovery potential of the products, where recovery includes both recycling and
energy recovery.

According to IEC/TR 62635, almost all components of the relay can be sent for recycling.
However, due to recycling issues with plastics containing flame retardant additives, poly-
carbonate parts might be non-recyclable. In theory, polycarbonate is recyclable and with
developing techniques and controlled waste stream it is possible, but in practice it usu-
ally goes directly to energy recovery. For that reason, two different scenarios are pre-
sented for the recyclability potential of the device. Rubber and silicone-based materials
are not considered recyclable due to lack of data and can be sent directly for energy re-
covery. The non-recyclable materials including polycarbonate are 0.39 kg and represent
7.6 % of the total reference product of 5.15 kg.

For calculating the global warming potential (GWP), an emission factor (EF) of 0.40 kg
CO -eq/kWh is assumed, which is representative for Europe:
