Abstract
Nanocellulose has been reported to be a very useful biomaterial with applications
in biomedical, pharmaceutical, built industry, automobile, aerospace and many more.
Its advantages over synthetic fibers include renewability, energy efficiency, cost
effectiveness, biodegradability and good mechanical and thermal properties. However,
the production of cellulose nanoparticles (CNPs) has focused more on woody plant
sources. Non-woody biomass constitutes a large group of plant sources that are yet to
be given the proper attention for utilization as raw material for nanocellulose particle
production. This group of lignocellulosic biomasses is generally obtained as waste
from farming activities, home gardens or office wastes. They are majorly composed
of cellulose, hemicellulose, and lignin. However, their composition varies widely from
one plant source to another. The variation in their composition results in limitations in
the procedures employed in extraction of CNPs and of processing of the extracted
CNPs. This means that different biomasses may have different ways by which CNPs are
extracted from them. Therefore, this review intends to x-ray these variations, its effect
on the structural properties of extracted CNPs and possible ways such limitations can
be mitigated.
