US-headed Darling Ingredients Inc., a global developer, and producer of sustainable natural ingredients from edible and inedible bio-nutrients has announced that it plans to reduce emissions from its wastewater treatment plants (WWTPs) at some of its rendering facilities by capturing biogas and converting it to renewable natural gas (RNG) in partnership with compatriot RNG developer, owner, and operator, GreenGasUSA.
According to a statement, the initial plan is to start with five Darling Ingredients rendering facilities in the United States with the opportunity to expand to other facilities depending on feasibility and market conditions.
Darling continues to find value where others see waste. By combining our deep knowledge of RNG from our position in Europe with the capabilities of GreenGas in the United States, Darling can significantly decrease its greenhouse gas emissions and help develop a successful RNG business in the US, said Randall C. Stuewe, Chairman and CEO of Darling Ingredients.
Majority owned by the IFM Net Zero Infrastructure Fund (IFM NZIF), an open-ended fund managed by IFM Investors, GreenGasUSA partners with global businesses to help reduce their environmental footprint by producing RNG and other renewable products, like carbon dioxide (CO2), clean water, and agricultural nutrients.
GreenGasUSA has operational RNG facilities at agricultural and food processing sources across the country, with proven success in installing, commissioning, and operating gas upgrading equipment; RNG and CO2 product compression and transportation; and existing pipeline injection infrastructure.
We are excited to announce this landmark agreement with Darling Ingredients. 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, said Marc Fetten, CEO and Founder of GreenGas USA.
