INTERRA Green Initiatives

INTERRA was honored in December 2017 by the IRTBA with the 2017 Green Industry Achievement Award.

Green initiatives began at INTERRA’s headquarters in Bolingbrook by changing interior and exterior lighting in the shared office building to energy efficient LED bulbs. These actions were soon followed by the implementation and innovation of several key measures: the addition of new rooftop solar panels, recycling, incorporating electric vehicles into company fleet, community outreach, the development of the Green Committee, among many other actions.

Village of Bolingbrook Mayor Roger Claar performed the ribbon cutting in November, celebrating a new rooftop 220 panel, 75.9 Kilowatt DC Solar Panel system. Approximately, 100,000 kWh energy production meets about 80 percent of the company’s electricity consumption, equivalent to almost 2,400 trees being planted yearly or 150,000 pounds of carbon dioxide emissions being eliminated.

Another key measure is through recycling the following: concrete and asphalt samples, paper, glass, metals, electronics, chemicals, and plastic. Among the chemicals being recycled is Trichloroethylene (TCE) where the chemical is reclaimed to be used again and the sludge is disposed of. The recycling of concrete and asphalt accounts for 108 tons yearly. Another effort in 2017, INTERRA began converting company fleet to electric and presently has four electric chargers available to clients and staff.

As result of INTERRA’s green in-house projects and community outreach, approximately 496,000 pounds of carbon dioxide, a greenhouse gas, will not be emitted into the environment annually.

In December 2017, INTERRA accepted the Illinois Road and Transportation Builders Association (IRTBA) awarded INTERRA, Inc. the 2017 Green Industry Achievement Award recognizing the firms many green initiatives.

In May 2018, the IRTBA announced that INTERRA President Sanjeev Bandi has been invited to serve on the IRTBA Green Council Board of Directors.
