SEA circular is an initiative of UN Environment Programme and the Coordinating Body on the Seas of East Asia (COBSEA) to inspire market-based solutions and encourage enabling policies to prevent marine plastic pollution. SEA circular is working in six countries in South-East Asia – Cambodia, Indonesia, Malaysia, the Philippines, Thailand and Viet Nam, from 2019-2023. The project aims to reduce adverse impact of land-based plastic leakage into the marine environment by ensuring that less plastic is wasted at source and management of the plastic value chain is improved in South-East Asia. Given inadequate waste management systems in the region, the project focuses on the lifecycle stages of (i) production of plastic products, (ii) plastic use, and (iii) collection sorting/recycling to ensure that less plastic is wasted and strategically prevent plastic litter entering the ocean.
