Description

technical field

[0001] The present invention relates to purifying crude glycerol obtained from kitchen waste and various uses of the purified crude glycerin. Background technique

[0002] Today, cooking oil is usually recovered and converted into biodiesel for use as fuel, and currently 10 wt% of the glycerol used in biodiesel production is provided by waste glycerol. Although glycerol has been widely used in the cosmetic, food, and pharmaceutical industries, it is expensive to purify waste glycerol to high purity for commercial applications, so landfill disposal is usually the fate of waste glycerol.

[0003] Bacterial fermentation may be an economically viable route to utilize low-value waste glycerol and produce high-value-added biological products such as biodegradable plastics. Biodegradable plastics can come from renewable biomass sources. Polyhydroxyalkanoates (PHAs) are linear polyesters produced in nature by bacterial fermentation of sugars or lipids and are accum...
