Ardagh Group’s North American glass division has been awarded a further four Energy Star plant certifications for superior energy performance from the Environmental Protection Agency (EPA).

Ardagh is the only U.S. glass container manufacturer to earn this recognition.

The four Ardagh Group manufacturing facilities are located in Bridgeton, New Jersey; Dunkirk, Indiana; Madera, California; and Milford, Massachusetts.

All four plants have demonstrated best-in-class energy performance and, on average, perform within the top 25% nationwide for energy efficiency when compared to similar plants across the country.

Meeting strict energy efficiency performance levels set by the EPA, Ardagh Group’s four recognised glass facilities have improved energy performance by upgrading and optimising furnaces, utilising recycled glass, installing energy-efficient lighting fixtures and repairing air compressor leaks, among several other energy-saving initiatives.

Since 2010, nine Ardagh Glass facilities in North America have received 26 certifications between them.

“Ardagh Group is honoured to remain the only U.S. glass container manufacturer to earn the prestigious Energy Star plant certifications,” said John Riordan, President and CEO of Ardagh Group, Glass – North America.

“We are committed to reducing the environmental impact of our business by upgrading and optimising our manufacturing operations and focusing on recycling programs at our facilities, illustrating our dedication to environmental responsibility and our goal of being the glass packaging supplier of choice.”

Energy Star was introduced by the EPA in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency.

Today, the Energy Star label can be found on more than 60 different products, as well as new homes and commercial and industrial buildings that meet strict energy efficiency specifications set by the EPA.

Over the past twenty years, American families and businesses have saved a total of nearly $230 billion on utility bills and prevented more than 1.7 billion metric tons of greenhouse gas emissions with the help of Energy Star.

“Improving the energy efficiency of our nation’s industrial facilities is critical to protecting our environment,” said Jean Lupinacci, Chief of the Energy Star Commercial & Industrial Branch.

“From the plant floor to the board room, organisations are leading the way by making their facilities more efficient.”
