  • Process of producing bioenergy with low carbon dioxide emissions and zero-waste of biomass
    Patent number: 9902977
    Abstract: Disclosed herein is a bioenergy production system with reduced carbon dioxide emissions and process wastes; including a process for producing a bioalcohol and a biogas by subjecting a biomass, such as: herbaceous and woody plants, fruit pulp, freshwater and sea algae, grains, aerobic and anaerobic sludge, saccharides, polyols and carbohydrates, to a combined process of a biosaccharification/alcohol fermentation, including a biomass pretreatment process; and a process for producing a methane biogas with a reduced level of carbon dioxide and hydrogen sulfide, via an algae cultivation process with a view to purifying the carbon dioxide and hydrogen sulfide contained in the biogas; wherein, when the algae to be cultivated is microalgae, biodiesel is produced by subjecting the harvested microalgae to a biodiesel manufacturing process while recycling the glycerol and the saccharide-containing waste produced as byproducts to the biosaccharification/alcohol fermentation process, and when the algae to be cultivated is
