17 Apr 2023 --- Zero Waste Europe (ZWE) is calling on EU policymakers to make material recovery and biological treatment (MRBT) of mixed waste mandatory. The organization has found the method is cost-competitive with controversial, traditional incineration practices and would help drive down the bloc’s emissions footprint. Janek Vahk, climate energy and air pollution program coordinator for ZWE, tells PackagingInsights that current and recently revised legislation like the Packaging and Packaging Waste Directive (PPWD) could be a “good first step” for lawmakers to oblige waste managers to use MRBT.
