Abstract

The rapid escalation of plastic production has prompted researchers to seek innovative and sustainable methods for recycling plastic waste to prevent its accumulation in landfills and mitigate its adverse effects on the environment and human health. One way is by incorporating plastic waste into construction materials. This study imparts a review on the application of plastic waste in the production of construction bricks through mechanical recycling processes, with a specific focus on compiling information on the manufacturing process as well as identifying potential emissions, occupational health hazards, and environmental risks. Through a review of 100 existing empirical studies, including those available in open-access journals specifically relevant to the study's focus, it became evident that there is limited research investigating the emissions, occupational health impacts, and environmental risks associated with the production of bricks from plastic waste. Due to this information gap, the study extrapolated health risks and environmental impacts from comparable mechanical recycling processes. Our findings indicated that the manufacturing process, which consists of plastic collection, sorting, washing, drying, shredding, melting or extrusion, cooling, and molding, is likely to emit several air pollutants, including but not limited to heavy metals, persistent organic pollutants, particulate matter, and volatile organic compounds. Individuals involved in the production of plastic-waste bricks likely face a heightened risk of adverse health outcomes, particularly in settings where appropriate safety measures and control mechanisms are lacking. While the scientific literature currently offers a limited examination of the environmental impacts stemming from these pollutants, the research identified significant concerns related to microplastic presence in wastewater and heavy metal contamination in nearby soil and sediments. This study recommends that small-scale recycling operations mandate the use of personal protective equipment, implement adequate control strategies such as general and local ventilation systems, and prioritize the recycling of plastics known to pose minimal risks to human health. There is a pressing need for further research to accurately characterize the emissions produced during the manufacturing process and to comprehensively evaluate the consequent health and environmental hazards.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
