This knowledge compendium has been developed to serve as a useful reference compiling all the publications that SEA circular and its partners have released as at December 2021. The compendium supports the project’s objective of bringing the learnings and experiences of SEA circular together into a solutions report that highlights case studies, pilot reports and relevant learnings to share progress, advocate for and bolster actors that are initiating, replicating or scaling up circularity initiatives in the plastic value chain. These publications have been linked to the 10 acceleration solutions identified during the SEA of Solutions 2021 conference and agreed by the ASEAN Member States, resulting from collective and constructive dialogue among key stakeholders in the sector.
