Weak or insufficient waste management and recycling (WMR) infrastructure drives solid waste pollution including marine debris and ocean plastic. Therefore, an essential component to any domestic resource efficiency approach, including circular economy approaches, is establishing environmentally sound WMR infrastructure that enables collection and processing of recyclable materials for their sustainable recovery through recycling. This project built the capacity of policy makers and stakeholders to address WMR challenges by familiarizing them with four key policy areas and associated methodologies that comprise the enabling environment WMR infrastructure, specifically: supporting environmental regulation; improving understanding of waste and recyclable materials; materials quality and processing health and safety standards; and enabling policies for recycling infrastructure investment including public-private partnerships.
