Bioconversion Process of Barley Crop Residues into Biogas—Energetic-Environmental Potential in Spain

نویسندگان

چکیده

Barley fields reach 1.7 million hectares in Spain, of which 320,000 are used to produce malt, generating 450,000 tons crop residue from barley intended for malt production. One way treat this waste an environmentally sound, energy-sustainable and economically cost-effective manner is anaerobic digestion. The biogas generated can be as fuel a renewable source energy (providing solution the supply problem environmental point view). It has been shown that, when treated along with sludge Upflow Anaerobic Sludge Blanket (UASB) reactor, produces about 1604 NmL per 100 g; content methane 27.486%. development process studied novel indicator, hydrogen generation, it determined that takes place two phases. demonstrated beginning energy-efficient therefore external uses regions have at least 6000 planted barley. At best, considered, given region, equivalent 115 MW power plant. could 10 thousand homes year. Therefore, considered com-plies Sustainable Development Goals #1, #7, #10, #12 #13. guarantees access isolated areas or problems, results 55.4% reduction emissions equivalent-CO2 (which equals 38,060 Spain).
