Circular Economy: From Linear to Circular Design, E-Waste, Plastic Pollution, and Extended Producer Responsibility
Circular Economy core design principles (Ellen MacArthur Foundation is the field’s most important advocacy organization): Design out waste (consider material disassembly, repairability, and upgradeability at the product design stage); Circulate materials (redefine waste as raw materials, not garbage); Regenerate natural systems (agricultural practices supporting soil health and biodiversity, not depletion).
E-Waste: The Fastest-Growing Waste Stream
The UN Global E-Waste Monitor (2022) shows approximately 53.6 million tonnes of e-waste generated annually, with only approximately 17.4% entering formal recycling channels. Large volumes of e-waste are exported through informal channels to Ghana, Nigeria, India, and China’s informal dismantling operations, where workers (often including children) are exposed to lead, mercury, cadmium, and other toxic substances without protection.
Extended Producer Responsibility (EPR): policy mechanism requiring producers to take responsibility for their products’ entire lifecycle (including disposal phase). The EU’s WEEE Directive is the most mature EPR policy example, requiring manufacturers to fund electronics collection and recycling.
The Plastics Crisis: From Macro to Microplastics
Approximately 8 million tonnes of plastic enter the ocean annually; microplastics have been detected in human blood, placentas, breast milk, and lungs, with health effects still under study. 2023 Global Plastics Treaty negotiations under UNEP aim to establish a legally binding framework for global plastic production and use reduction — one of the most anticipated global environmental agreements since the Paris Agreement.
