June 19, 2024. Domino’s has recently announced a new partnership with Vanguard Renewables aimed at tackling the pressing issue of food waste. Through this, the company has made significant strides in this area by diverting 243.75 tons of inedible waste from landfills, thereby reducing greenhouse gas emissions by 156 tons of carbon dioxide equivalent emissions in 2023.
The process utilizes Vanguard Renewables’ advanced Farm Powered Anaerobic Digesters, strategically located on dairy farms. These facilities play a crucial role in the sustainable management of food waste. They operate by mixing inedible food waste from Domino’s with dairy cow manure in a sealed anaerobic digester where it decomposes with the help of naturally occurring microbes.
This decomposition generates biogas, which is then purified and converted into renewable natural gas (RNG). This gas serves as a clean, versatile fuel that powers homes, businesses, and vehicles, offering a renewable alternative to fossil fuels.
Moreover, this partnership positively impacts the agricultural sector by producing digestate from the anaerobic digestion process. This byproduct is a nutrient-rich fertilizer that supports sustainable farming practices on the dairy farms hosting the digesters. It helps reduce reliance on chemical fertilizers, enhances soil health, and boosts crop productivity, fostering a holistic approach to sustainability.
