Peanut shells can clean water

peanut shella are an effective tool for cleaning wastewater. The agricultural waste removes poisonous copper ions from industrial wastewater. A new study says the shells perform better than many other waste products such as saw dust. Though the industry uses many chemical processes to remove heavy metals for wastewater, most of them are highly expensive. This new method seems to be cheaper and eco-friendly.

Peanut shell is the first waste product found to be highly efficient in cleaning wastewater. It cleans 95 per cent of the copper ions. Wastewater from electroplating, pulp and paperboard industries contain copper and affects marine and human life. Copper, for example, can damage the human liver.
