Addressing Plastic Waste Challenges in Africa: The Potential of Pyrolysis for Waste-to-Energy Conversion

Clean Technologies, Год журнала: 2025, Номер 7(1), С. 20 - 20

Опубликована: Март 5, 2025

Plastic waste poses a significant challenge in Africa and around the world, with its volume continuing to increase at an alarming rate. In Africa, estimated 25–33% of daily is made up plastic, posing threat environment, marine life, human health. One potential solution this problem waste-to-energy recycling, such as pyrolysis, which involves conversion materials into oil, char, non-condensable gasses through thermochemical process absence oxygen. Given abundance continent’s energy challenges, pyrolysis offers sustainable solution. This review delves concept products, thermodynamics, endothermic kinetics, presenting it promising way address plastic Africa. Despite African Union’s goal recycle waste, continent faces barriers achieving target, including infrastructural, economic, social difficulties. It crucial implement strategies for managing mitigate environmental degradation promote cleaner healthier living environment. Pyrolysis technology highlighted viable management, can convert valuable byproducts syngas. Case studies from countries like South Nigeria demonstrate scaling management issues while generating job opportunities. underscores need investment, regulatory support, public awareness overcome challenges unlock full Embracing method could lead economic benefits continent.

Filling the Gaps: Tracing 12 Types of Non-commodity Plastics in China’s Plastic Socioeconomic Metabolism

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 10, 2025

Recent plastic flow research has largely focused on commodity plastics (PE, PP, PVC, PS, ABS), yet a sizable share of other polymer types remains understudied. These non-commodity suffer from inconsistent definitions, complex classifications, and data gaps, which hinder accurate assessment their production, use, end-of-life management. This study develops dynamic material analysis to investigate 12 key "non-commodity" in China─including PET, PU, seven engineering plastics, three thermosetting plastics─and addresses these knowledge gaps. Our results show that 2022, China produces approximately 85 million tonnes polymers, volume comparable with 35% used products the remainder non-plastic applications (e.g., fibers, rubber). PET is predominantly employed short-lifespan packaging, whereas find use longer-lifespan applications, underscoring need for targeted recycling strategies─particularly chemical PU thermoset products. Revisiting scope "plastics" using scientific criteria can help mitigate definitional ambiguities guide more effective policymaking. By improving availability tracking this underexplored category, our lays groundwork assessments interventions reduce pollution.
