“We are thrilled to welcome US Ecology employees to the Republic team,” Jon Vander Ark, president and CEO, said in a statement. “With US Ecology’s deep expertise in specialty waste treatment, this acquisition strengthens our position as a leading environmental services company offering one of the most comprehensive sets of products and services to our customers. “

Vander Ark commented on the joint partnership with Archaea Energy to progress towards its 2030 sustainability goal of increasing the use of biogas. The 39 renewable natural gas (RNG) projects will be the country’s largest RNG portfolio build to date. According to the companies, Republic and Archaea will convert landfill gas into pipeline-grade RNG that can be used for a variety of applications to move gas from fossil fuels.

The majority of projects are expected to come online between 2023 and 2027.

“This joint venture, along with our 17 landfill gas, is expected to generate approximately $100 million as we continue to be recognized for our commitment to sustainability,” Vander Ark said.
