Abengoa inaugurates demonstration plant with Waste-to-Biofuels (W2B) technology

Abengoa recently inaugurated a demonstration plant using Waste-to-Biofuels (W2B) technology. The plant has a capacity to treat 25,000 tons of municipal solid waste (MSW) from which it will obtain up to 1.5 million liters (396,000 gallons US) of bioethanol for use as fuel.

The demonstration plant, located in Babilafuente (Salamanca, Spain), uses W2B technology developed by Abengoa to produce second-generation biofuels from the organic fraction of MSW using an enzymatic hydrolysis treatment followed by fermentation. During the transformation process, the organic matter is treated in various ways to produce organic fiber that is rich in cellulose and hemicellulose, which is subsequently converted into bioethanol.

Abengoa is contemplating other processing of the other components of municipal solid waste—including recyclable (plastics, PET, metal) and the non-recyclable CDR (mainly mixtures of rubber, wood and textiles) and other plastics—to obtain diesel or bioplastics.

Such an integrated solution result in less than 10% of managed MSW being sent to landfill as inert waste.
