Stillage management can be a challenging task for distilleries and ethanol plants. The common practice of using stillage to create animal feed (dried distillers’ grains) is not only energy-intensive and expensive, but also requires a farmer customer base for transport and purchase. However, implementing anaerobic digesters and biogas upgrading systems can effectively manage stillage while providing numerous financial and environmental benefits to your operation.
By using stillage as feedstock for an anaerobic digestion system, you can achieve a sustainable stillage management solution while simultaneously producing renewable energy. The produced biogas can be used to generate electricity, upgraded for injection to the natural gas grid, or further upgraded and liquefied for vehicle fuel. Furthermore, with the Inflation Reduction Act of 2022, tax incentives are now available, making these systems even more appealing and cost-effective.
Another benefit is that the digestate output can be processed into useful applications, such as nutrient-rich fertilizer and animal bedding. Implementing anaerobic digesters and RNG upgrading systems also demonstrates your commitment to sustainable leadership. By incorporating renewable energy sources into your operation, you can significantly reduce your carbon footprint and lessen your dependence on traditional heating and electricity sources.
