Calculating environmentally weighted recyclability of consumer eletronic products using different environmental assessment models

The EWRQ approach focuses on the determination of environmentally weighted recycling scores rather than weight-based recycling scores. This approach describes much better what is happening in end-of-life scenarios, from the environmental perspective. It is a very powerful concept in assessing recyclability and end-of-life scenarios in general. It takes into account the environmental impact of treatment steps and the value of secondary materials. This paper presents the results of integrating three completely different environmental assessment models into the EWRQ concept: the Eco-Indicator '95, the Eco-Indicator '99 and the Fraunhofer IZM Toxic Potential Indicator TPI.
