Description
Charred plant material can pull the stubborn forever chemicals out of water, but plain farm char usually loses to costly activated carbon. Wei Zheng and co-authors designed a better char in this 2026 study. They pre-treated wood with lime sludge, a free waste from drinking water plants, before charring it.
By tuning the sludge dose, charring heat, and cooking time, the team boosted the char pore structure and its grip on the chemicals. The designer char closed much of the gap with activated carbon at a fraction of the cost. Forever chemicals are now found in waters worldwide and resist breakdown. A cheap sorbent made from two waste streams could widen cleanup beyond rich utilities.
