Biomass is a type of renewable resource, organic, and non-fossil
material of biological origin such as wood and crop waste from agriculture.

Biomass derived from organic matter is a raw material to produce biodiesel.
Biodiesel is an alternative liquid fuel for diesel engines consisting of

the alkyl monoesters of fatty acid from vegetable oils or animal fats.
The biodiesel production process also produces a large quantity of

cheap by-products, namely glycerol and triglycerides. Glycerol is a water-
soluble polyol which provides access to a range of monomers for

subsequent polymerization. The new glycerol-based polymer has a
different composition and can be tailor-made according to the application.

Besides, the main constituents of plant oils are triglycerides, which are
the product of esterification of glycerol with three fatty acids. Triglycerides

have been used in the synthesis of cross-linked polymers via functional
groups, double bonds, and the number of carbons in fatty acids. It is an

alternative to using renewable resources for maximum benefit, create
value-added and environmentally friendly concerns.
