Title
Environmental-friendly strategy for biocatalytic conversion of waste glycerol to glycerol carbonate
Abstract

In this work, the conversion of waste glycerol from biodiesel production to glycerol carbonate (GlyC) as added-value product has been investigated. The transformation of waste glycerol to GlyC has been achieved taking the advantage of dimethyl carbonate (DMC) reaction with glycerol catalyzed by heterogeneous lipase biocatalyst under solvent-free conditions. The biocatalyst design was the lipase enzyme anchored on magnetic nano-particle surface via covalent binding. Waste glycerol with different matrixes according to the feedstock patterns (e.g. soybean, sunflower, rape, corn, olive, palm, and residual oil) has been tested for GlyC bio-synthesis. Content of MeOH, H2O, metals and salts from sample matrix (e.g. waste glycerol) was characterized using gravimetric and energy dispersive X-ray fluorescence (EDXRF) spectrometry techniques. Impurities effects of the waste glycerol on the performance of the biocatalytic process and also different strategies to avoid them were investigated.
