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). Fig. 1 Fig. 3 Activity Fig. 2 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 well as the Fig. 3 processing technique used to make the composite. Methods & Results Fig. 4 Fig. 5 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. Conclusions Fig. 8 Fig. 7 Fig. 6 Fig. 9 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.
