Brewing a Greener Future with Coffee Waste

Brewing a Greener Future with Coffee Waste

Spent coffee grounds, a significant byproduct of global coffee consumption, present an environmental challenge due to their volume and potential harm to wildlife. A groundbreaking study, however, has discovered that these coffee grounds can be transformed into an effective adsorbent for removing the neurotoxic herbicide bentazone from water. By activating the carbon in coffee grounds using zinc chloride, researchers achieved a 70% efficiency in eliminating bentazone. This not only addresses the problem of herbicide pollution but also promotes a circular economy, turning waste into a valuable resource for environmental protection.
