Abstract

It has been shown that two novel green technologies (Low temperature microwave activation and Starbon^® materials preparation) could be efficiently applied for bio-waste utilisation. Combination of these processes could help transfer polysaccharide reach biomass to high value products such as fuels, chemicals, materials and solvents. Both technologies are scalable and could be applied for multi-tonne processes. The microwave (MW) technology focuses on depolymerisation of large organic molecules to high value products. The most promising from the industrial application perspectives is ability of MW irradiation to activate lignocellulosic materials at very low temperature. In inert atmosphere MW assisted pyrolysis could produce a number of high value chemicals such as levoglucosan, levoglucosenone, HMF and furfural. The grade yield and high purity of these products are guaranteed by low temperature of the process and high controllability of microwave irradiation. In the presence of water solution the lignocellulosic biomass could be converted to different types of mono- and oligosaccharide. This sugars-reach solution could be used for further biological/enzymatic treatment and production of bio-gas and bio-ethanol. Starbon^® technology is complimentary to microwave approach helping to convert helical-structured polysaccharides (starch, pectin, alginic acid and xylan) to mesoporous carbonaceous materials. Starbon^® materials due to its textural properties flexibility and controllable functionality could be applied for recovery and purification of critical metals such as lithium, cobalt, beryllium, silver and gold from aqueous systems. High degree of mesoporosity and large pore diameter (larger than 5nm) of Starbon^® enables to perform reversible adsorption of bulky industrial days.
