AgVault Develops Ethanol's Next Path to Value Creation Beyond Fuel

OMAHA, Neb., Aug. 5, 2025 /PRNewswire/ -- With little to no efficiency gains remaining in the ethanol production process, AgVault has developed a next generation fermentation technology solution designed to significantly improve the profitability of existing ethanol production facilities.  Using low-cost carbohydrate production from existing ethanol facilities, the technology creates significant value-added products such as high grade yeasts and yeast products, enhancing and expanding livestock and companion animal feed production. 

AgVault's novel precision fermentation system is designed to be co-located and integrated with an ethanol facility.   Composed of three major parts: carbohydrate feedstock preparation, precision fermentation, and downstream product processing,  AgVault's precision fermentation process is innovative due to its high efficiency and kinetics of production, which improves operations, lowers costs, and generates superior returns on invested capital. "AgVault's co-located facility with 16,000 tons of annual production capacity generates a 35% ROI with its superior yeast product sold at 90% of conventional yeast prices" according to AgVault co-founder and President Kevin Dretzka.

Precision fermentation is a process in which microorganisms like yeast and bacteria are used to produce microbial proteins. AgVault's method differs from traditional methods of protein production, providing a more efficient and sustainable approach. "Precision fermentation is revolutionizing protein production with sustainable and efficient alternatives to traditional protein production" explains Russ Zeeck, co-founder and COO.  "Global market adoption of precision fermentation is influenced by consumer awareness and demand for eco-friendly products.  Untapped markets offer significant opportunities for the continued expansion of precision fermentation products such as food, nutraceuticals, enzymes, fertilizers, soil microbiome."

With its patented precision fermentation system, AgVault technology enables ethanol facilities to produce alternative products with improved value creation starting with feed and evolving to food and biotech alternative products such as cosmetics, plastics, and textiles. 

The entry level micro-organism for AgVault precision fermentation is one the ethanol industry is quite familiar with – yeast.  AgVault technology provides ease of operations integration, improving ethanol fermentation while producing a superior, reliable, and low-cost product for feed and food downstream markets, including:

• Improved protein content (>50% microbial protein with improved digestibility) when included in a feed ration
• All yeast protein; not "by-product" yeast from the ethanol process ,often with mixed specifications and non-yeast additives
• Improved amino acid bioavailability for up-take when used in feed diets
• Increased essential amino acids
• Improved digestibility
• Improved and increased complex carbohydrate and Beta-glucan content
• Reduced GHG emissions in dairy cows

AgVault's fermentation technology solution offers ethanol producers a solution to diversify revenue, improve margins, and increase enterprise value by participating in the rapidly growing precision fermentation industry without reliance on government incentives or subsidies.
