Republic Services highlights RNG efforts in sustainability report

Republic Services Inc. released its 2017 Sustainability Report on Aug 29. Within the report, the company outlines progress it has made on several environmental goals, including those related to the production and use of renewable natural gas (RNG).

In 2014, as part of its Blue Plant sustainability platform, Republic Services set several sustainability goals, including a goal to develop at least two landfill gas-to-energy projects per year through 2018. The company said it achieved that goal for 2017.

Republic Services is also making progress with the use of RNG fuel. For more than a decade, the company has been making investments in compressed natural gas (CNG) trucks and fueling stations. Republic Services said its continued investments in CNG trucks and fueling stations has enabled the company to being making a seamless transition to RNG. The company cites the California Air Resources Board as finding RNG to be the lowest carbon intensity of all the alternative technologies on the market today.

According to Republic Services, its approximately 93 percent of its California fleet runs on RNG. The company also noted that in some cases, it sources RNG from its own landfills.

The company’s sustainability report indicates it currently operates 68 landfill gas and renewable energy projects. Collectively, Republic Services estimates its landfill gas-to-energy projects have the capacity to generate enough renewable energy to power 208,000 homes. The company’s newest project, located at the Pinehill Landfill in Longview, Texas, is expected to generate 404 million cubic feet of RNG per year, enough to offset carbon emission equal to the use of more than 19 million gallons of gasoline annually.
