Alcohol and ethanol distilleries utilize feedstocks and generate valuable by-products. These by-products can be managed through filtration, treatment, or conversion to DDGS and biogas. Implementing a biogas plant cuts or eliminates fuel costs, enhancing alcohol production affordability. Biogas replaces natural gas or bunker oil in boilers. Stillage can be processed through anaerobic digestion or concentration to 30% solids, improving efficiency and allowing for steam reuse. This approach is effective for large-scale operations, optimizing capacity. Concentrating stillage to 30% achieves optimal digestion conditions. Vertical CSTR technology is efficient, saves energy, and is suitable for urban settings. It offers a cost-effective alternative.
