Barrelhouse Brewing Conducts Feedstock Testing With Greenbelt Resources

PASO ROBLES, CA - Sept. 4, 2017 - Greenbelt Resources Corporation (OTC: GRCO) has agreed to perform feedstock testing with Barrelhouse Brewing Company to test its trub as a potential feedstock for Greenbelt's Paso Robles ECOsystem project known as PRECO.

The trub, a byproduct of the brewing process, will be tested for viable conversion to bioethanol and animal feed.

When complete, PRECO, a commercial scale waste-to-energy interconnected system, will produce up to 500,000 gallons of bioethanol and other byproducts.

PRECO places Greenbelt's ECOsystem technology in the center of the local business community by converting wastes from local breweries, wineries and other ag businesses into bioproducts including animal feed, fertilizer and potentially a high value human protein source.

The products can then be purchased by other local businesses. The goal of PRECO is to reduce costs or generate revenue for all parties within the ecosystem by converting local wastes into local resources

In California, companies incur an expense when removing waste, and breweries must pay to have the spent trub picked up and properly disposed.

Should trub prove an ideal feedstock, Greenbelt may save Barrelhouse a portion of the costs associated with current removal methods and provide them with a greener solution.

"With waste becoming a bigger societal concern many don't see there are opportunities to turn trash into treasure," says Eng.

"Our testing will determine how trub from Barrelhouse performs as a feedstock and if well, the resulting bioproducts will be greener, more sustainable products."

Founded in 2013 by Jason Carvalho and Kevin Nickell, Barrelhouse Brewing Company has quickly become the largest all American owned brewery in San Luis Obispo County.

With three taproom locations to date and more in planning, Carvalho says Barrelhouse is consistently looking for ways to reduce waste and increase efficiency.

"We are currently looking for new ways to reduce costs associated with disposal. Should trub become a viable feedstock, it will help save us some money while also helping us to attain our sustainability goals," says Carvalho.

Trub has already been proven as a suitable feedstock in prior feedstock testing for another local brewery.
