Reflections on bio-based PET and plastic waste management: a responsible research and innovation approach
Summary
This perspective piece examines the responsible research and innovation (RRI) implications of using bio-based enzymes and microorganisms to depolymerize plastic waste, identifying stakeholder concerns about scalability, GMO containment, additive management, and regulatory readiness. It highlights that biological plastic degradation is a promising but socially complex solution to the dual crises of plastic pollution and greenhouse gas emissions.
Plastics drive twin crises: persistent pollution and greenhouse gas emissions. Bio-based approaches using enzymes and microorganisms to depolymerise plastics and valorise monomers show promise but raise societal, ethical and regulatory questions central to Responsible Research and Innovation (RRI). In this Perspective, we reflect on RRI implications of bio-based plastic degradation, informed by stakeholder discussions across the plastics value chain and public engagement. We identify broad support alongside concerns about scalability, interaction with existing recycling, governance and containment of genetically modified organisms, management of additives and contaminants, and the roles of regulation and economic incentives in enabling adoption.
