Environmental and Economic Evaluation of Biochar Application in Wastewater and Sludge Treatment
AI summary Read the abstract
This chapter reviews how biochar — a carbon-rich material made from organic waste — can remove microplastics, heavy metals, and organic pollutants from wastewater and sludge. Biochar is presented as a cost-effective and environmentally friendly treatment option compared to conventional technologies.
Contamination of wastewater and sludge has become a major environmental concern in recent years. Wastewater treatment facilities (WWTFs) represent important sources of microplastics, heavy metals, and organic pollutants. The purpose of this chapter is to demonstrate that biochar can be an environmentally friendly and economically viable alternative to other conventional technologies for treating polluted wastewater and sludge. The fundamentals of life cycle assessment (LCA) related to biochar applications in wastewater and sludge treatments are discussed together with technical and economic insights.

Sludge-derived biochar: Physicochemical characteristics for environmental remediation
AI summary Read the abstract
This review examines how sewage sludge can be converted into biochar, a carbon-rich material useful for cleaning up environmental contaminants including microplastics and heavy metals from water and soil. The process turns a waste product into an effective pollution filter while reducing the volume of sludge that needs disposal. This approach is relevant to microplastics research because biochar could help remove plastic particles from contaminated water and agricultural land.
Biochar-based adsorption technologies for microplastic remediation in aquatic ecosystems
AI summary Read the abstract
This review examines the use of biochar, a carbon-rich material made from organic waste, as a tool for removing microplastics from water. Biochar can effectively adsorb microplastic particles due to its porous structure and surface chemistry, and it can be produced cheaply from agricultural waste. The technology shows promise as an affordable and sustainable approach to reducing microplastic contamination in waterways, though challenges remain in scaling it up for real-world water treatment.
