Topic: Advance Technologies for Valorization of Waste Biomass
Details
Generally, the earth produces 173 billion tons of materials through photosynthesis every year,which contains energy equivalent to 10-20 times the world's total energy consumption, but its current utilization rate is less than 3%. Biomass waste generated from the processing and consumption of the biomass resources is the most abundant renewable resource on earth, which can be converted into various forms of energy, including biofuels, biopolymer, and biogas via biological/chemical approaches. The biomass carbon energy cycle refers to the flow of carbon within biomass as they are used for energy production and then recycled back into the environment. By integrating the biomass carbon energy cycle, we can create a sustainable and regenerative system that manipulate the carbon cycle to produce renewable energy while minimizing environmental impact and facilitating resource efficiency. In this presentation, innovation bio-valorisation technologies developed including low C/N ratio composting approach,engineering modification of two phase anaerobic digestion design with metabolic manipulation for higher biogas outputs, and innovative catalytic conversion of waste biomass for hydrogen production.An estimate of about 3.5 to 5% reduction of total carbon dioxide emission from China will be achieved by adopting this carbon energy cycle approach.
