There is an increasing interest in the end-of-life management of polymers present in waste electric and electronic equipment (WEEE), which is mainly due to the high recycling and recovery targets set by the European WEEE directive.

Mechanical and biological treatment has been established as a concept of handling municipal solid waste. The biological process aims to degrade the organic fraction of the waste to a stabilized product through fermentation and rotting processes. The final maturation produces a depositable residual waste.
