Introduction
Chitin Nanofibrils (CN) is a crystalline polysaccharide with a needle-like form
(Fig.1). Derived from crustaceans waste, it is a natural biodegradable polymer with
haemostatic, bacteria static and wound healing properties.
Due to the fact that application of wound dressings might be painful for the patient,
sustained release is a desirable property of the formulation enabling the reduction in
need for dressing change. Moreover, for its crystal purity and physicochemical
characteristics, CN has been used as filler for composite materials to produce fibers
by the casting (Fig.2) or electrospinning technology (Fig.3).

CN, in fact, used as filler for composite materials has shown to be an adaptable engineering material
useful to reinforce the fibre strength and elasticity (Fig.4), increasing the biodegradability of the
masterbatch used for producing food containers or shoppers (Fig.5). Naturally, its reinforcing effect
depends of the aspect ratio of the crystal chitin used, and therefore
on
its
origin
and
purity,
as

as

processing technique used to make the composite.

Finally by the gelation method, the electronegative CN (Fig.6) reacting with
other natural electronegative polymers, make stable block copolymeric
micro/nano lamellae and particles (Fig.7) which, embedded into
pharmaceutical, or cosmetic emulsions, are been used to produce effective
medical devices (Fig.8) and innovative cosmetics for skin aging (Fig.9).
This interesting natural polymer, in fact, for its nanosize dimension, high
surface area, high absorptive, biodegradable, non toxic, renewable, low
density and easy modification of its structure seems able to create a healthy
ecosystem capable to easily interact with cells, growth factors, proteins and
other compounds of the human body.

In conclusion, Chitin Nanofibrils could be considered a new raw material useful to support the
production of different goods. It is also Interesting to underline that industrial production and use of this
polymer, obtainable from fishery's waste, is in line with the EU, OECD and USA Directives. They, in fact,
support the growth of a Bio-Green-Economy for a sustainable industrial, development, based on a
major use of by-products accompanied by a reduction of water and energy consume, necessary to
safeguarding the human health and the biodiversity of our planet.
