PPG's Land Remediation Site

개요

To look at the gently rolling hills and meadows, it’s hard to imagine that 20 years ago the 300-acre parcel at PPG’s Barberton, Ohio, USA, chemicals plant was virtually lifeless. No grass, flowers or trees grew there. Even the weeds struggled to survive. That’s because the waste from more than 70 years of soda ash production – totaling more than 30 million metric tons, mostly in the form of limewater slurry – was pumped into six ponds, referred to as Lime Lakes. The result: 600 acres incapable of supporting vegetation. In 1899, when the Barberton plant was built, the impact of industrial wastes, including those from making soda ash for the production of glass, was unrecognized. But in the 1980s, PPG discovered a way to reclaim the lakes. By mixing selected municipal sludge with the lime, PPG has been able to return land to nature.
