Waste Sovereignty and Plastic Colonialism: Environmental Power and Populism in the Global Political Economy of Waste

Plastic pollution is one of the most pressing environmental problems of the twenty-first century, but the governance of global plastic waste is remarkably unequal. Significant volumes of plastic waste from developed countries are exported to developing countries in the Global South, where waste management infrastructure and regulatory capacity are often limited. While this movement of waste across borders is frequently discussed in terms of recycling efficiency or waste management capacity, these transactions are deeply embedded in unequal power relations within the global political economy. This article proposes a theoretical framework called Waste Sovereignty Theory (WST), which explains how international waste trade reproduces environmental power asymmetries between exporting and importing nations. Drawing on political ecology, environmental justice, postcolonial environmental governance, and emerging scholarship on environmental populism, the paper conceptualizes transboundary plastic waste flows as a form of plastic colonialism in which the ecological costs of production and consumption in wealthy countries are displaced onto less powerful states. The article introduces a Waste Sovereignty Theory Framework (WST Framework) that links four key dynamics—plastic production, transnational waste trade, governance inequality, and sovereignty claims—to explain contemporary struggles over environmental authority in the Global South. Using illustrative cases from Southeast Asia and Africa, the article demonstrates how states and communities respond through waste import bans, stricter regulatory regimes, waste repatriation policies, and the promotion of domestic recycling industries. These responses are interpreted not only as efforts to reclaim environmental governance but also as expressions of environmental populism, whereby affected populations challenge environmental burdens perceived as imposed by distant political, economic, and technocratic elites. Waste sovereignty thus emerges as both a claim to environmental justice and a form of political resistance against unequal structures of global environmental governance. The article argues that addressing the global plastic crisis requires more than technological improvements in waste management; it demands institutional reforms capable of confronting the structural inequalities embedded in contemporary systems of production, consumption, and environmental governance.
