INTERRA To Host Ribbon Cutting With Bolingbrook Mayor Celebrating Going Green

BOLINGBROOK, IL – INTERRA, Inc. will host a ribbon cutting event at 4 p.m., Wednesday, November 1st, at its headquarters with Bolingbrook Mayor Roger Claar celebrating the installation of new rooftop solar panels and many other green initiatives being done by INTERRA.

The event, INTERRA Going Green, will be held indoors at INTERRA, 600 Territorial Dr., Suite G, in Bolingbrook. Food and beverages will be served at the event which is open to the public.

INTERRA President Sanjeev Bandi began discovering ways to reduce the carbon footprint for the company, which provides engineering, testing, and inspection services in support of construction, development, environmental, and geotechnical projects.

“I researched environmentally friendly ways of doing business,” Bandi said. “I wondered what more we can do and saw great potential and ways to include renewable energy into green initiatives.”

A total of 220 solar panels accounting for 75.9 kW DC power were installed on the rooftop in September. These panels provide 100,000 kW of energy annually and will meet more than 80% of INTERRA’s electricity consumption. In terms of environmental benefits, the energy produced is equivalent to saving 150,000 pound of carbon dioxide emissions over a year or 3,800 equivalent trees planted. Replacing old light fixtures with new LED fixtures, using daylight harvesting and occupancy sensors, results in an additional elimination of 462,000 pounds of carbon dioxide emissions annually.

INTERRA continues to show a commitment to improving sustainability measures in other areas as well: recycling asphalt and concrete laboratory samples and plastic molds, making accessible two Electric Vehicles charges for clients and staff, lab chemical recycling, electronic recycling, among many other green practices.

In 2017, the engineering firm began converting company fleet to electric as well and presently has four electric vehicles and several staff who utilize the Electric Vehicle chargers. The company continues to identify new green opportunities that will benefit the environment.
