Food processing and packaging company Tetra Pak is installing a solar power array at its headquarters for its goal to use 100 percent renewable electricity in the U.S. by next year.

The business has the same goal for worldwide operations in about 80 countries by 2030. It already gets half of its electricity globally from renewable sources.

The photovoltaic (PV) panel array, expected to be complete in November, will produce energy each year equivalent to about 80,000 gallons of gasoline, the company says.

The array will help power its Denton, Texas, campus that includes offices, a pilot-scale food production plant and a carton materials factory. The complex already has a rooftop solar array.

"Using electricity from renewable resources makes sense for the environment and for business," says Jason Pelz, vice president of circular economy – Tetra Pak Americas and Southeast Asia and Oceania. "It ensures we’re not tied to a finite resource to operate our business. And by lowering our environmental footprint, we’re also supporting our customers’ goals to reduce their overall climate impact."

Tetra Pak, part of the RE100 consortium of companies committed to renewable energy, uses a combination of methods to work toward its goal, including solar installations and the purchase of International Renewable Energy Certificates.
