GreenGasUSA and Darling Ingredients partner to reduce emissions and repurpose waste through the production of Renewable Natural Gas (RNG) 


Charleston, South Carolina, June 5, 2024 – GreenGasUSA and Darling Ingredients Inc. (NYSE: DAR) are pleased to announce their partnership to produce renewable natural gas (RNG) and capture CO2 from the wastewater streams at Darling’s facilities in the U.S. The collaboration is expected to result in material greenhouse gas (GHG) emissions reductions at Darling’s facilities from the installation of gas upgrading systems, CO2 capture systems, as well as generate other beneficial co-products. 

At the core of its business, Darling Ingredients champions sustainability, and GreenGasUSA is a leading producer of RNG from environmental and industrial waste streams.  Through Darling and GreenGasUSA’s collaboration they aim to accelerate the development of innovative solutions to unlock value from waste streams and deliver significant environmental benefits such as GHG reductions. 

 “We are excited to announce this landmark agreement with Darling Ingredients,” said CEO and Founder of GreenGasUSA Marc Fetten. “It is our mission at GreenGas to help businesses reduce their environmental impact by providing solutions that generate economic benefits. Darling Ingredients has been at the forefront of the effort to repurpose waste and integrate circularity into industrial operations and GreenGas is proud to support this mandate by partnering to convert agricultural and food waste into a valuable renewable energy product.” 

“Darling continues to find value where others see waste,” said Randall C. Stuewe, Chairman and CEO of Darling Ingredients. “By combining our deep knowledge of RNG from our position in Europe with the capabilities of GreenGas in the U.S., Darling can significantly decrease its greenhouse gas emissions and help develop a successful RNG business in the U.S.”
