Environmental impacts of plastic waste management practices in urban suburbs areas of Zimbabwe
AI summary Read the abstract
This paper assesses the environmental footprints of various plastic waste management strategies, including landfilling, incineration, mechanical recycling, and chemical recycling. The analysis offers a comparative lifecycle perspective to help identify which approaches minimize greenhouse gas emissions, resource loss, and pollution across different plastic types.
The study was conducted to explore aspects surrounding plastic waste management in Makokoba high-density suburb, Bulawayo, Zimbabwe. Guided by the pragmatic reasoning, the study employed a descriptive cross sectional design. Referral sampling was used to select 32 questionnaire respondents while purposive sampling was used to select 4 key informants. Quantitative and qualitative data collection techniques were used to collect the data using semi-structured interviews, questionnaires and observations. Microsoft Excel was used for quantitative data analysis and content analysis was used to analyse qualitative data. The study investigates the current state of plastic waste management practices, the challenges faced by residents and local authorities and associated environmental problems. The study established that informal markets were the main source of plastic waste (50%). The study also established that plastic waste led to land pollution (56%), disturbance of the natural ecosystem (17%) and blockage of the reticulation system (17%). Existing plastic waste management approaches were less effective since it focuses on disposal. Hence, the study recommends a sustainable plastic waste management framework which supports integrated approach and circular economy.

Investigation on Plastic Wastes in Nyamasheke District, Rwanda: Quantification, Characterization and Management Framework Design
AI summary Read the abstract
Researchers studied plastic waste in rural Rwandan markets and found that even though almost everyone knew about the country's plastic bag ban, most plastic waste (mainly bottles and food wrappers) was still being burned or dumped in the open rather than properly disposed of. Burning plastic releases toxic chemicals into the air, and dumping it contaminates soil and water — both of which can expose nearby communities to harmful substances through breathing, drinking water, or food grown in polluted soil. The findings show that banning certain plastics isn't enough on its own — real change also requires better trash collection systems and disposal habits, a l
