Microplastic Removal from Water Using Biomass‐Based Carbon: A Review of Recent Advances
AI summary Read the abstract
This review evaluates the potential of carbon materials derived from biomass, such as agricultural waste and wood, for removing microplastics from water. Researchers found that these materials offer advantages including low cost, abundant raw material sources, and effective removal capabilities. The study highlights biomass-derived carbon as a promising sustainable technology for addressing microplastic contamination in aquatic environments.
Microplastics (MPs) have emerged as priority contaminants in aquatic environments in recent years. Growing public concern surrounds their environmental and health impacts, as well as their contribution to future global environmental challenges. As emerging contaminants, key challenges lie in developing efficient methods for their detection, quantification, and removal from aqueous media. Numerous techniques for MP remediation from water have been reported in the literature. Among these, biomass-derived carbon presents several advantages, including low cost, abundance of raw materials, efficient removal capabilities, and sustainability. This review critically evaluates the potential of biomass-derived carbon for the removal of MPs from water. It provides a concise overview of MP sources and their environmental pathways. Additionally, it summarizes the synthesis methods and characteristics of biomass-derived carbon. The review elaborates on the removal performance and underlying mechanisms of MPs by these materials. Key challenges and future research recommendations are also discussed. This review provides valuable insights for researchers, summarizing the current research landscape and outlining strategies for advancing MP remediation using biomass-derived carbon.

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.
Efficient Removal and Resource Utilization of Microplastics in Aquatic Environment by Biomass-derived Functional Carbon
AI summary Read the abstract
Scientists are developing a special charcoal-like material made from plant waste that can soak up microplastics from water, potentially offering a cheaper, greener alternative to current cleanup methods. Since microplastics have been found in our food, water, and even our bodies, better tools to filter them out of water supplies could help reduce our overall exposure to these particles. That said, this technology is still in development—researchers note it's expensive to scale up and its real-world safety and effectiveness need more testing before it can be widely used.
