Annotation: Microplastic pollution is a great concern due to its widespread presence, transfer in food chain and negative impacts. However, the sources of microplastics remain poorly understood. This dissertation aims to address the knowledge gap by investigating the generation and abundance of microplastics in little-studied but potentially significant sources: organic waste treatment and landfills. To achieve this, a fast and inexpensive protocol has been developed for analyzing microplastics in solid organic-rich waste samples. By implementing this protocol, the quantity and characteristics of microplastics present in organic outputs after processing mixed municipal solid waste and separately collected organic waste were determined and compare.
Furthermore, the research explores the impact of mechanical-biological treatment processes and composting on the generation and release of microplastics. This examination helps assess the impact of these waste treatment methods in exacerbating microplastics pollution. Additionally, the study investigates the fate and distribution of microplastics within non-hazardous landfills, providing valuable insights into their long-term behavior within landfill bodies.
The findings from this research will contribute to a deeper understanding of the sources, pathways, fate and potential risks associated with microplastics in organic waste management systems. Ultimately, this work can inform the development of strategies and policies aimed at effectively tackling microplastics pollution and setting limits for microplastics in organic waste outputs.
