Guardian Glass Plant Earns Energy Star Certification in DeWitt, Iowa

The Guardian Glass float glass plant in DeWitt, Iowa, has earned the U.S. Environmental Protection Agency’s (EPA) Energy Star certification, which signifies that the industrial plant performs in the top 25% of similar facilities nationwide for energy efficiency and meets strict energy efficiency performance levels set by the EPA.

Guardian Glass improved its energy performance by managing energy strategically across the entire organization and by making cost-effective improvements to its plant, according to the company.

“Commercial buildings and industrial plants account for nearly half of the nation’s energy,” says Jean Lupinacci, chief of the Energy Star Commercial and Industrial Branch. “But through benchmarking performance and a strategic approach to energy management, it is possible for companies to save energy, save money and protect the environment.”

Operating since 1996, the DeWitt plant completed a major capital project in 2017 that expanded glass production and added new environmental control technologies. The plant applied for certification based on 2019 data.

Vitro Architectural Glass Renews Cradle to Cradle Certification

Vitro Architectural Glass (formerly PPG Glass) announced that its entire range of coated and uncoated architectural glasses has been renewed as Cradle to Cradle Certified by the Cradle to Cradle Products Innovation Institute. Cradle to Cradle Certified is a recognized measure of safe, sustainable products made for the circular economy across the globe.
In order to receive this certification, eligible products are evaluated for environmental and social performance across five major sustainability categories: material health, material reuse, renewable energy and carbon management, water stewardship and social fairness.

In addition, Vitro Glass was awarded a Material Health Certificate at the Gold level. This document certifies that in producing its glass products, Vitro Glass refrains from using chemicals of concern and is transparent about all chemicals used in products across its supply chains.

“Architects, fabricators and building products professionals of all kinds rely on the Cradle to Cradle Certified Product Standard as a guide for purchasing and designing with products that have a positive impact on both people and planet,” says Nathan McKenna, director of marketing and innovation. “Since Vitro Glass became the first U.S.-based glass company to have its entire range of products Cradle-to-Cradle Certified in 2008, we have continued to offer one of the industry’s most extensive selections of clear, ultra-clear, tinted, solar control and passive low-E glasses qualified to this rigorous, globally-recognized lifecycle standard.”

In addition, Vitro’s production is also energy-conscious. Its Fresno, Calif., plant has earned EPA Energy Star® certification. The Fresno plant, which operates an oxygen-fuel-powered glass furnace, earned the certification by registering an energy performance score ranked in the 75th percentile or higher among other float glass manufacturing plants in the United States.
