Anaerobic Digestion Plants
Vanguard Renewables Converts Organic Waste into RNG
mursal rahman — June 5, 2026
Anaerobic digestion plants are expanding the role of organic waste in renewable energy production. Vanguard Renewables recently broke ground on a new facility in Minnesota that will process more than 300 tons of food and beverage waste per day, converting discarded organic materials into renewable natural gas (RNG) and nutrient-rich fertilizer. Located at Wagner Dairy, the facility creates a closed-loop system that connects waste diversion, energy generation and agricultural operations.
The facility demonstrates how anaerobic digestion can transform waste streams into valuable resources while supporting local energy infrastructure. By converting organic waste into renewable fuel and agricultural inputs, the system helps reduce reliance on landfill disposal and synthetic fertilizers while creating additional value from existing materials. As demand for renewable energy and resource-efficient practices continues to grow, facilities like this may become increasingly important for connecting waste management, energy production and farming within integrated regional ecosystems.
