We believe that accident prevention, environmental protection, and efficient manufacturing go hand-in-hand. Each employee must act with integrity to keep our company a safe and healthy place to work while respecting the environment.

Guardian Glass receives Innovation Award from Charles Koch and Dave Robertson

The Guardian Glass Goole, England float glass plant received an Innovation Award at the Koch Industries Energy Conference held in Wichita, Kansas.

In 2014, the Goole team received funding to examine ways to recover heat loss through its furnace. The team worked hard to develop and deliver a system comprised of a steam boiler and turbine that generates electrical power by recovering waste heat from the flue gas. The site now recovers waste heat from the melting process. Since May 2016, this innovation has provided 22 percent of the site’s electricity demand and in 2017 generated a savings of £830,000 (~$1 million).

“Though the interest has been there, waste heat recovery systems are not at all common in the float glass industry,” explains Jordan Featherstone, engineering manager at Goole, who accepted the award on the team’s behalf. “This was a pilot project for Guardian Glass to prove the concept and successfully recover energy and eliminate waste in our melting process using fewer resources than our competitors. A key driver was our obligation and responsibility to society to become a preferred partner and create value for our customers, employees and other key constituents.”

Jordan led an integrated project team that included plant engineers and team members from the engineering excellence and energy sourcing capabilities.

The project has increased Guardian’s knowledge of waste heat recovery for the float glass process. We can now apply these lessons to make better decisions and potentially replicate the success of waste heat recovery in additional plants.

The award was presented by Koch Industries Chairman Charles Koch and President and COO Dave Robertson. The Energy Conference is a biannual gathering and opportunity for subject matter experts across the Koch enterprise to share knowledge and best practices.

“It was great to connect with colleagues at other Koch companies and understand each other’s challenges and opportunities,” Jordan says. “It reinforces that we are all part of something much bigger, and we all have an opportunity to leverage knowledge and work together to improve the rate of transformation.”

Tatuí Implements Wastewater Recovery Project

Treating process wastewater from the wet coater lines at Guardian Glass plants is a priority for the environment. In Tatuí, Brazil, the Project Team took on a challenge to create a more environmentally sustainable and cost-efficient process. Here's how.

Guardian Glass wet coaters are used for the production of mirrors and other coated glass products. During the process, annealed or fully tempered glass is thoroughly cleaned by the application of cleaners in conjunction with oscillating scrub brush units. After the glass is cleaned and rinsed, the surface of the glass is further processed to produce either mirror or specialty painted glass products.

The wet coater line has two wastewater streams, the reverse osmosis (R.O.) reject water and the wet coater process wastewater. The plant typically recovers approximately 90 percent of the R.O. reject water and 93 percent of the wet coater wastewater. The team completed research on many water technologies and designed a system to recover and reuse the wastewater. The system removes contaminants, such as silver, tin and iron, and separates any remaining solids. The resulting water then goes through an ultra-filtration process before being recirculated and reused.

Another opportunity was the reuse of the R.O. reject water, instead of sending the reject water to the local sewage treatment plant. Working with the plant's water supplier, the Project Team was able to analyze the composition of the water, and determined that it was okay to directly reuse the reject water in the float line cooling water system. The plant now recovers and reuses approximately 90 percent of the R.O. reject water.

"By optimizing current wastewater management practices, the Project Team is now saving the plant over 100 million liters of water per year, and reducing costs to the sewage company," says Carlos Cardia, Engineering Manager. "Not only is it environmentally beneficial for the community, but also financially beneficial to the plant."

The Project Team continues to look for opportunities to use fewer natural resources to eliminate waste.

Waste Heat Recovery System Earns Energy Star Certificate

The Waste Heat Recovery System (WHRS) at our Goole, UK float glass plant, recently received a Certificate of Appreciation from the United States Environmental Protection Agency and its ENERGY STAR® Program.

ENERGY STAR is the government-backed symbol for energy efficiency, providing simple, credible, and unbiased information that consumers and businesses rely on to make well-informed decisions.

The WHRS was selected as a Top Project at the 2017 ENERGY STAR Industrial Partner and Focus Meetings in September. Ray Siada, director, Corporate Energy Management, Guardian Glass, was on hand to accept the Certificate.

“The WHRS project is the first-of-its-kind for our company, and demonstrates our long-term commitment to sustainability,” says Ray. “This is a great example of creating value using fewer resources, while increasing productivity and profitability.”

The installation at Goole began in 2015 and was fully operational in 2016. The float glass process requires a large amount of energy. Regenerators on either side of the furnace capture waste heat but heat still escapes the furnace.

The WHRS uses a complex method of capturing waste heat from the furnace without disrupting the delicate convection currents which flow inside the furnace as the batch material is turned into glass. The system converts waste heat from our melting process to electric power.

Among the benefits, the system:

  • Improves the company’s indirect carbon footprint
  • Generates 30% of the plant’s electricity needs, which is enough to power 3,700 homes
  • Has additional capability to facilitate increased electrical power generation with a larger furnace or increased temperature of exhaust gases toward the end of a furnace campaign.
  • Reduces 33% of the wasted heat during the melting process

“The system is a long-term investment that significantly reduces the plant’s environmental impact,” adds Ray. “We expect to see this system installed at other Guardian Glass facilities in the future.”

This Certificate further promotes our efforts, and those of Koch Industries, to the efficient use of natural resources while operation in a way that protects the safety, health and wellbeing of our employees, the environment and our communities. Earlier in 2017, Koch was named an ENERGY STAR Partner of the Year for Energy Management.
