The enormous leakage of plastic waste in Southeast Asia currently shows no signs of abating, but there are reasons for optimism:

• There are signs that plastics lifecycle management is being put on a firmer foundation in the region’s largest countries. After years of neglect, governments are finally putting policies in place to regulate different aspects of plastics production, use and disposal.
• Recognising that plastic waste reduction is a cross-border challenge, the Association of South-East Asian Nations (ASEAN) is also taking action, launching a regional action plan for combatting marine plastic waste in May 2021.
• While their governments get up to speed with policy implementation, a vast informal sector of waste collectors and aggregators is performing a critical role in the region’s plastics ecosystem, delivering waste to numerous recyclers. Although fragmented and unwieldy, the informal sector can be a significant contributor to future plastics circularity if integrated more closely with the formal parts of the ecosystem.
• Finally, non-government organisations (NGOs) and social enterprises have sprung up across the region to stem the tide of plastic waste where governments and the private sector have been inactive or ineffective. These are attracting the material support of international organisations, which are also advising governments and mobilising multi-stakeholder initiatives to promote plastics circularity.

However, there is no understating the scale of the challenge the region’s countries face—no less than the creation of a new framework for managing the lifecycle of plastic products, extending from design to production to consumption to disposal and beyond. The ultimate goal must be to close this loop and achieve plastics circularity.

As detailed in this programme’s flagship report, the Plastics Management Index (PMI) compares how 25 countries manage their plastics lifecycle. The PMI includes four South-east Asian nations: Indonesia, Malaysia, Thailand and Vietnam. The countries’ scores and ranks are based on their performance in three categories of indicators: governance, capacity infrastructure and stakeholder engagement. The index’s main findings specific to South-east Asia are as follows:
