The study aims to guide the selection of the most appropriate waste-to-value technology for different materials as part of a circular economy approach.
Global trends of pyrolysis research: a bibliometric analysis
This systematic review maps global research trends in pyrolysis, a process that uses heat to break down waste materials. The findings are relevant to microplastic pollution because pyrolysis is being explored as a method to break down plastic waste, and understanding which approaches work best could help reduce the flow of microplastics into the environment.
Hazardous air pollutants from the waste incineration industry : formation mechanisms, distribution characteristics, and potential environmental risks
This study investigated how hazardous air pollutants including dioxins, furans, and heavy metals are formed and distributed during industrial waste incineration. While focused on incineration emissions rather than microplastics directly, waste incineration is relevant to plastic waste management and the broader question of how plastics should be disposed of.
Recovery of plastic waste through its thermochemical degradation: a review
This review examines pyrolysis as a promising technology for recovering valuable chemical compounds from plastic waste, which reached approximately 368 million tons of global production in 2020 alone. Researchers discuss how thermal and catalytic degradation can convert different types of thermoplastics into high-energy-value products. The study also highlights the environmental and health impacts of plastic accumulation, including the effects of microplastic consumption on human and animal health.
The manufacturing process and consequent occupational health and environmental risks associated with the use of plastic waste in construction bricks in small-scale recycling plants
Researchers reviewed health and environmental risks in small-scale facilities that recycle plastic waste into building bricks, finding that the manufacturing process likely releases microplastics, heavy metals, and toxic air pollutants, posing serious health hazards to workers — especially where safety measures are absent.
Fate of microplastic during pyrolysis of sewage sludge
Researchers examined how pyrolysis as a sewage sludge treatment method affects the fate of embedded microplastics, finding that thermal treatment largely destroys plastic particles. However, some polymer-derived volatile compounds transferred to pyrolysis gases and oils, suggesting that microplastic destruction does not eliminate all associated chemical risks.
Optimisation of Process Parameters to Maximise the Oil Yield from Pyrolysis of Mixed Waste Plastics
Researchers optimized the process parameters for thermal pyrolysis of mixed waste plastics to maximize oil yield from HDPE, polypropylene, and polystyrene. The study used response surface methodology to identify ideal conditions for converting plastic waste into pyrolytic oil, supporting chemical recycling as a strategy to reduce plastic pollution.
Influence of operating parameters on the yield of micro-plastics from plastics incineration.
Researchers studied how different incineration conditions affect the yield and type of microplastics produced when plastics are burned, finding that temperature and oxygen levels significantly influence the output. The findings raise concerns that incomplete incineration of plastic waste — a common disposal method globally — can generate and release microplastics rather than eliminating them.
An Appropriate Technology Approach for Utilizing Plastic Waste Derived Cooking Fuel to Reduce Indoor Air Pollution from Solid Fuel Cooking
This study explored slow pyrolysis of plastic waste as an appropriate technology for communities in developing regions to produce cooking fuel from waste materials that would otherwise be mismanaged. The approach was assessed for feasibility, safety, and community adoption potential as a low-cost plastic waste valorization strategy.
