Evaluating the abundance of two particle size ranges of polyethylene microplastics in pig manure under integrated black soldier fly and biochar-amended composting treatments.

The transfer of microplastic (MP) pollution from biomass waste to soil presents a significant challenge for resource utilization and treatment technologies. This study investigated combining black soldier fly larval bioconversion with biochar co-composting to control MPs in biomass waste. In the initial bioconversion process, polyethylene (PE) MPs of two different sizes were added: approximately 150 μm (Series 150) and approximately 300 μm (Series 300).

Synergistic effect and mechanism analysis of biochar regulator on heavy metal passivation and microplastic degradation in sewage sludge compost.

Heavy metal passivation and microplastic in sludge threaten environment and cause human health risks, and thus necessary to find effective remediation strategies. To solve this issue, the synergistic effect of biochar on pollutants remediation during sludge composting is still not well explored. In this study, different doses of cotton stalk biochar (0 %, 2.
