Southern California brewery [Sierra Nevada](https://www.trendhunter.com/trends/non-alcoholic-brews) has announced a partnership with E-Fuel to turn their beer waste into ethanol using the Efuel100 Micro Fueler. The ethanol will primarily be used to power the on-site vehicles at Sierra Nevada, but it's possible that the ethanol would be made available for employees or the general public. Sierra Nevada has already done quite a bit for the environment. According to [Tree Hugger](https://www.trendhunter.com/trends/save-a-tree-pee), Sierra Nevada sells 1.6 million gallons of beer waste to farmers annually to use as dairy feed. ## Trend Insights (Trend Hunter) - Score: 2.1/10 - Popularity: 7% | Activity: 49% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Why This Trend Is Growing - **Eco-friendly Brewing:** The partnership between Sierra Nevada and E-Fuel can inspire breweries to invest in technology that converts brewery byproducts to fuel. - **Sustainable Energy Production:** The Efuel100 Micro Fueler creates an opportunity for companies to repurpose their waste materials for energy production, reducing their carbon footprint. - **Circular Economy Solutions:** The use of brewery waste to produce ethanol demonstrates the ability to create a closed-loop system that uses waste as a resource, inspiring other industries to look for similar solutions. ### Industries Being Reshaped - **Brewing:** The brewing industry can leverage similar technology as E-Fuel's Efuel100 Micro Fueler to reduce its environmental impact and repurpose brewery byproducts for sustainable fuel production. - **Agriculture:** The use of Sierra Nevada's beer waste as dairy feed can inspire other companies to find similar uses for their waste materials in agriculture and reduce waste sent to landfills. - **Renewable Energy:** The conversion of brewery waste to ethanol for fuel production signals an opportunity for the renewable energy industry to explore the potential for other waste-to-energy solutions. ## Related on Trend Hunter - [Crisp Non-Alcoholic Brews](https://www.trendhunter.com/trends/non-alcoholic-brews.md) - [Bread Surplus-Created Beers](https://www.trendhunter.com/trends/upcycling-food-trend.md) - [Sustainable Solar-Powered Beers](https://www.trendhunter.com/trends/oakham-sun-city.md) - [Brewery-Led Sustainability Initiatives](https://www.trendhunter.com/trends/sierra-nevada-1.md) - [Low-Emissions Alcohol-Free Beers](https://www.trendhunter.com/trends/carlsberg-sweden-and-einride.md) - [Spent Grain Alcohol Products](https://www.trendhunter.com/trends/zenso-alcoholic-beverages.md) - [Regenerative Grain Lagers](https://www.trendhunter.com/trends/kernza-lager.md) - [Leftover Bread-Based Beers](https://www.trendhunter.com/trends/hop-foundry.md) - [Distilled Beer Whiskeys](https://www.trendhunter.com/trends/ruthless-whiskey.md)
