Rice Husk Biochar Filtration for Microplastic Removal from Raw Water at a Drinking-Water Depot in Aceh Besar, Indonesia

Summary

Tiny plastic particles too small to catch with normal water treatment are turning up in drinking water, especially from small local water refill stations. This study found that filtering water through biochar made from burnt rice husks, a cheap, plant-based material, can effectively strip out these microplastics before the water reaches your glass. It's a promising, low-cost solution that could help reduce your exposure to microplastics without requiring expensive treatment upgrades.
