Winery Wastes Evaluated for Potential as Biofuel Feedstocks

Greenbelt Resources Corporation has agreed to perform feedstock testing with Central Coast Wine Services (CCWS) to test various wastes generated in the winemaking process as potential biofuel feedstocks.

The wastes will be tested for Greenbelt's "Paso Robles ECOsystem" project, a local waste-to-energy system. Wastes with successful results will be locally converted by Greenbelt's technology into sellable bioproducts such as bioethanol, feed and fertilizer.

CCWS will be working with Greenbelt to test the viability of taking various streams of remaining ethanol-containing elements, such as by-products of the fermentation process, and converting it into high-grade bioethanol.

Waste derived feedstocks to be tested or are currently being tested include pomegranate husks, mandarin oranges, pistachio hulls, bagels, brewery wastes, sweet potatoes, sugar beets, and a variety of waste sugar and/or alcohol containing beverages.
