“…Global plastic production increased from 2 million tonnes in 1950 to 380 million tonnes in 2015, with a total output of 7.8 billion tonnes (~28%) produced in China, of which 9% were recycled and 79% were disposed in landfills (Geyer et al, 2017; Li et al, 2021; Plastics Europe, 2016). Microplastics (MPs) are smaller than 5 mm in size, representing an emerging threat to the function of ecosystems and biota.…”

The accumulation of plastics in the soil ecosystem poses an increasing environmental concern worldwide. However, little is known about the effect of plastic concentrations on soil properties and soil biota. In this study, we investigated the effect of low‐density polyethylene (LDPE) microplastics (MPs) on the chemical and microbial properties of agricultural soil using a set of microcosm experiments. The soil was incubated for 100 days with LDPE at concentrations of 0%, 0.1%, 1%, 3%, 5%, and 7% at 25°C with 70% water‐holding capacity. Along with soil chemical analysis, we conducted an analysis of soil microbial properties on the first day and again after 100 days of incubation. LDPE concentrations of ≥1% significantly (p < .05) decreased the pH but increased the electrical conductivity of the soil in comparison with the control (0% LDPE at 100 days). Increasing the LDPE concentration did not affect the soil exchangeable cation content or the available Pb concentration. Firmicutes were the most abundant phyla in the soil on the first day, whereas Proteobacteria, Firmicutes and Actinobacteria became dominant in all treatments after 100 days. An increasing LDPE concentration increased the abundance of Actinobacteria and decreased Proteobacteria. Principal component analysis demonstrated that only 7% LDPE was positively correlated with Actinobacteria, indicating that higher concentrations of LDPE contributed to the growth of this phylum. The findings of this study imply that MP contamination could affect soil chemical properties and microbial activity and that these effects primarily depend on MP concentrations in soil.

“…In addition, plastic polymers have been attempted for conversion into useful compounds through pyrolysis, gasification of thermal oxidation ( Ephraim et al, 2016 ). Nanda et al ( Li et al, 2022 ) reviewed the thermochemical conversion (e.g., including pyrolysis, gasification, and liquefaction) of plastic waste to fuels, and concluded that pyrolysis was by far the most widely researched conversion technology compared to liquefaction and gasification. Owing to the unexpected COVID-19 outbreak, the demand for surgical masks has increased dramatically since early 2020 ( You et al, 2020 ), and mismanagement of single-used surgical masks has resulted in the generation of a large amount of mask waste.…”

“…Owing to the unexpected COVID-19 outbreak, the demand for surgical masks has increased dramatically since early 2020 ( You et al, 2020 ), and mismanagement of single-used surgical masks has resulted in the generation of a large amount of mask waste. Li et al (2022) upcycled waste surgical mask into liquid fuel with a high heating value (HHV) of 43.5 MJ/kg. More importantly, environmental benefits and advantages of this upcycling approach were verified from a life-cycle perspective, as compared with conventional waste management approaches.…”
