D.G. Yuengling and Son, Inc. recently completed installation of an $8 million wastewater treatment system at its historic Pottsville, Pennsylvania brewery, which was part of an agreement with the U.S. Environmental Protection Agency (EPA). The pretreatment system is one of many environmental programs the company implemented under terms with the EPA towards reducing and managing the amount of organic materials, like sugar and yeast, in the wastewater the breweries send to the Greater Pottsville Area Sewer Authority for treatment.
