Analysis and treatment of wastewater from plastic recycling in Blantyre, Malawi
Monitoring and treatment of plastic washing wastewater from recycling processes is often overlooked, though the high pH, chemical oxygen demand, suspended solids, and oil and grease concentrations can be problematic (Ozdemir and Yel 2023). Treatment of wastewater from plastic recycling is critical to both public and environmental health, since solid waste, sanitation, and water are inextricably linked (Narayan et al. 2021). This thesis project will contribute to a closed-loop plastic recycling pilot for HDPE bottles in Blantyre, Malawi.
The aim of this thesis is to characterize wastewater from washing plastics during the recycling process in Blantyre, Malawi and propose context-specific treatment options.

In the course of the project, the student will be responsible for:
- Analyzing wastewater from plastic recycling (e.g. pH, COD, TDS, turbidity, etc.).
- Comparing cost and cleaning efficiency from different washing methods.
- Thinking independently but working collaboratively (industry, NGO, and academia).

This research looks for a master-level environmental engineering student who wants to complete 3 months of field work in Blantyre, Malawi and has experience with water sampling and analysis. Interested and qualified students are invited to contact Dr. Jakub Tkaczuk (jtkaczuk@ethz.ch).
