Two of the facilities are in Hershey, and the third is in Hazleton.

The Hershey Company Global Operations senior vice president Terence O’Day said the company has achieved ZWL at these facilities through a rigorous process of eliminating waste, recycling and converting waste to energy. Our employees understand the importance of sustainability across our company and are working together to reach our reduction goals.

Zero Waste to Landfill means that routine manufacturing waste has been eliminated from landfill disposal.

The company’s Hazleton plant achieved ZWL status this month, and the West Hershey plant became a ZWL facility in October 2011.

In addition, the $200m to $225m expansion of the West Hershey facility, announced in June 2010, is a Zero-Waste-to-Landfill construction project and the new addition will be ZWL upon completion later this year.

The plants recycle around 90% of the waste generated from operations and the remainder is converted to energy at nearby waste-to-energy incinerators located in Bainbridge and Harrisburg.
