Assessing Plastic Circular Economy Policies and the Use of Digital Technology in Africa

Researchers assessed plastic waste reduction policies across Africa using the Chatham Database, DITCh Plastic Survey, and a Nigeria case study, applying machine learning text analysis to policy descriptions. The analysis found that predominantly punitive ban-based policies are ineffective at driving circular economy transitions due to shallow regulation, exclusion of informal recyclers, enforcement gaps, and limited awareness, proposing digital technology as a strategic tool for improvement.

Macro problems from microplastics: Toward a sustainable policy framework for managing microplastic waste in Africa

Researchers critically reviewed regulatory and policy approaches to managing microplastic pollution across African countries. They found that while environmental monitoring studies demonstrate an urgent need for action, the effectiveness of existing plastic waste policies in Africa remains poorly understood. The study proposes a sustainable policy framework tailored to the unique challenges African nations face in reducing microplastic waste generation and environmental contamination.

Advancing Plastic Recycling: Challenges and Opportunities in the Integration of 3D Printing and Distributed Recycling for a Circular Economy

This review explores how combining 3D printing technology with distributed recycling could help communities process their own plastic waste locally rather than relying on centralized facilities. Researchers found that while this approach shows promise for creating a more circular economy, challenges remain around material quality, contamination, and economic viability. The study highlights community-based recycling as an important complement to traditional waste management systems.
