Problem or opportunity

Plastic pollution has emerged as a critical environmental challenge, prompting innovative recycling initiatives such as Tanzanian business Green Venture's conversion of plastic waste into plastic furniture. However, the sanding process in this production generates microplastics, which pose significant ecological and health risks.

Proposed solution

This study investigates the microplastic emissions during sanding and proposes a cost-effective solution to enhance dust collection without necessitating major equipment overhauls. By developing a vacuum attachment ombined with a shield to contain airborne particles, the research aims to mitigate microplastic release and improve workplace safety. The findings highlight the importance of tailored solutions for small-scale manufacturers in low-resource settings, emphasizing the need for practical approaches that prioritize local adaptability and sustainability

Next steps

While the study presents a promising solution, it also highlights the need for further research and development in this area. Field testing in Tanzania will be crucial to validate the design's effectiveness under real working conditions and to assess quantifiable air quality improvements.
