The increasing effort of the global community to reduce dependency on fossil fuels led to an
increase in the production of biodiesel and therefore the oversupply of crude glycerol …

The increasing use of bio-based fuels and fuel additives, among them biodiesel, causes
significant surplus of crude glycerol on the market which creates new challenges in terms of …

For every ton of biodiesel produced, about 100 kg of glycerol is also generated as a by-
product. The traditional method of removing glycerol is mainly by gravity separation or …

In the present work, crude glycerol was purified by a combined strategy of physicochemical
treatment and semi-continuous membrane filtration using a 5 kDa ultrafiltration tubular …

As a promising alternative renewable liquid fuel, biodiesel production has increased and
eventually led to an increase in the production of its by-product, crude glycerol. The vast …

Biocatalysis utilizes enzymes and microbial cells as catalysts for a wide range of
applications in biotechnology. Immobilization of biocatalysts on various materials has …

Chitosan is one of the readily available polymers with relatively high abundance,
biodegradable and sustainable materials with divergent functional groups that are employed …

The presence of impurities decreases the economic value of glycerol. Thus, glycerol
impurities must be greatly reduced if it is to be used as a fuel or feedstock for chemicals. A …

The purification of raw glycerin in biodiesel production can provide economic benefits and
help to avoid residue accumulation, thus reducing environmental impacts. In this work, the …

This study provides insight into the decolorization strategy for crude glycerol obtained from
biodiesel production using waste cooking oil as raw material. A sequential procedure that …
