Critical Risk Factors in Underperforming Waste-to-Energy PPPs: Indonesia and Vietnam

A new study by CoHASS Assistant Dean (Outreach) and Lecturer in the Public Policy and Global Affairs (PPGA) programme, Kai Xiang Kwa, has been published in Public Works Management & Policy, a leading peer-reviewed journal on public infrastructure and policy.

As Southeast Asia grapples with rising energy demand and growing waste challenges, many countries are turning to public–private partnerships (PPPs) to develop Waste-to-Energy (WtE) infrastructure. But these projects don’t always go as planned.

From construction delays to regulatory gaps and operational setbacks, WtE PPPs face a range of complex challenges. With high upfront investments at stake, understanding what drives success—or failure—is critical.

This study, by our takes a closer look at two major WtE projects in Indonesia (Jatibarang) and Vietnam (Soc Son), uncovering three key areas of risk: legal, social, and operational. Together, these insights shed light on how such risks can shape project outcomes and what policymakers and stakeholders can do to better navigate them.

This work adds to the growing body of research on sustainable infrastructure and governance in Southeast Asia.
