Abstract: The present invention relates to a method for production of ammonia, using an inorganic nanoparticle-microbial complex in which a nitrogen fixation reaction in a microorganism is improved by increasing the amount of inorganic nanoparticles entrapped in the microorganism. The present invention can produce ammonia at low temperature and low pressure conditions, compared to the conventional Haber-Bosch process of producing ammonia in high temperature and high pressure conditions and in a friendly environmental manner without emission of carbon dioxide that is released during conventional chemical synthesis processes, whereby the present invention may be a competitive alternative to the prior art for production of ammonia that has an unlimited potential as a future energy resource.

Abstract: A method is described for the production of a polyhydric alcohol from a urethane containing polymer. The method first provides a reaction mixture comprising said polymer, a solvent, which comprises a polyol capable of reacting with said polymer to depolymerize said polymer; and a catalyst, which comprises catalyst particles. Said polymer is depolymerized in said reaction mixture by reacting with said polyol to produce said polyhydric alcohol. A further step allows said reaction mixture containing said polyhydric alcohol product to separate into an, upper, product phase containing said polyhydric alcohol and another, lower, phase mainly containing said polyol and said catalyst. The catalyst is recovered from said another phase, while said polyhydric alcohol product is recovered from said product phase.
