Influence of operating parameters on the yield of micro-plastics from plastics incineration.
Summary
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.
Plastics account for a large proportion of domestic waste. However, micro-plastics will be produced after the plastic is incinerated. The purpose of this study is to find out the change rule of micro-plastics produced during incineration under different conditions. Combining micro-FTIR and PCA algorithm is a good tool to identify the micro-plastics. The PE, PP and PVC micro-plastics are distinguished using PCA-FTIR spectra. The results show different incineration conditions significantly affect the output of micro-plastics. The yield of micro-plastics increases with increasing temperature for both PP and PVC. And the yield of micro-plastics decreases with the increase in flow rate. The maximum amount of micro-plastics is produced by PE, which is 6.62 × 10 after 1 g PE incineration. The yield of micro-plastics in the co-incineration of PE and PP, as well as PE and PVC, significantly increased to 1.42 and 1.89 times of the calculated values, respectively. The nano-particles are also observed. The FTIR and EDS results show that the nano-particles are the products of incineration of plastics, including partly CH bond and unburned carbon, tar and ash.

Is incineration the terminator of plastics and microplastics?
Researchers extracted microplastics from the bottom ash of 17 different types of incinerators and identified them by micro-FTIR spectroscopy, demonstrating that incineration does not fully destroy plastic waste and that unburned microplastics persist in ash residues.
Quantity and morphology of microplastics in the Tehran and Nowshahr MSW incinerators ashes
Researchers sampled ash from two municipal solid waste incinerators in Iran over one year, finding microplastics present even after incineration. This indicates that current incineration practices do not fully eliminate microplastics and that incinerator ash may be a source of plastic pollution if applied to land or landfilled.
Can incineration completely eliminate plastic wastes? An investigation of microplastics and heavy metals in the bottom ash and fly ash from an incineration plant
Researchers examined fly ash, bottom ash, and surface soil from a municipal solid waste incinerator for microplastics and heavy metals, finding that incineration did not completely eliminate plastics — with fibers persisting in fly ash — and that fly ash heavy metal concentrations exceeded safety thresholds in several categories.
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.
Nanoplastic Particle Emissions from Plastic Smoldering Combustion
Researchers conducted the first systematic study of nanoplastic particle emissions from smoldering plastic combustion, testing five common plastic types. They found that burning plastics at low temperatures produces significant quantities of airborne nanoplastic particles along with volatile organic compounds. The findings identify smoldering combustion, such as in open waste burning, as a previously uncharacterized source of atmospheric nanoplastic pollution.
