What was done
This review synthesized data on the health hazards of plastic waste, global waste management disparities, emerging technical recycling interventions, and the impact of national regulatory frameworks such as single-use plastic restrictions and expanded producer responsibility schemes.
What was found
Globally, less than 10% of plastic waste is repurposed, with the majority incinerated or dumped, releasing hazardous emissions such as dioxins and furans. In low- to middle-income countries, particularly in Sub-Saharan Africa, only 39% to 45% of solid waste is adequately treated. For recycling technologies, chemical processes recover up to 97% of polyethylene terephthalate (PET), and enzymatic procedures show degradation efficiencies up to 90% within hours. Enforced regulatory frameworks in countries like Germany, Japan, and Rwanda have resulted in recycling rates above 41% and plastic waste reductions of up to 90%.
Why it matters
The review highlights the severe global and regional burdens of plastic waste and synthesizes policy and technological mechanisms required to mitigate resulting environmental and public health threats.
Limits
The abstract is truncated at the beginning and reports aggregate secondary figures rather than primary experimental or clinical data. No details are provided regarding search methodology, source selection criteria, or direct quantitative assessments of human health end-points.
