The concept of plastics revolves around creating polymer chains, and variations in chemical structures result in different types such as polyethylene, polypropylene, PVC and others.
Biodegradable and bio-based plastics They can either be synthesized from biological starting materials such as sugars, starches, oils, and proteins or made from fossil resources but possess chemical structures that allow biodegradation.

Asymptotic homogenization replaces the strain in a body with an asymptotic series, which represents the strain in the global composite body as a average strain at the highest structural level plus rapidly varying strains caused by the microstructure levels of the composite. .... 332211  uuuuu   (5) where u is the total displacement, u is the displacement on the most macroscopic level, iu , i = 1,2,… is the displacement at increasingly more microscopic levels, and  is the scale size between adjacent structure levels Inserting this representation of the strain into the differential equations describing the behavior of a deforming solid and solving the resulting equations with a numerical method, such as the finite element method, allows the effective behavior of the global body to be estimated from the known mechanical properties of the constituent phases [2].

In the current study, the morphological structure of the extracted cellulose specimen was investigated under SEM.
The surface structure of the isolated CNC was investigated under SEM at 20,000x magnification and an accelerating voltage of 15 kV.
The chemical structure of CNC was ascertained through an analysis of FTIR characterization.
According to the morphological analyses, the isolated CNC had a crystalline structure resembling a rode-like structure with length Mean about 507 ± 29 nm and a diameter of 70.02 ± 2 nm.
