Production of Biocomposites Based on Biodegradable Resin, Cellulose, and Lignin Using a Statistical Approach.

This work proposes the use of lignin and cellulose as fillers in the production of composites based on the resin Plantics-GX, a biopolymer commercialized by Plantics B.V., which serves as a sustainable alternative to conventional plastics as it is derived from renewable sources. In the context of the growing demand for environmentally friendly materials, the development of biobased composites represents a key step toward sustainable engineering solutions. A statistical mixture design of experiments was applied to ensure reliable modeling of the formulation and to optimize the component proportions to maximize the composite's mechanical performance. The tests reported in this paper showed that adding fillers to the Plantics resin increases the mechanical properties of the composite, making it mechanically stronger and more thermally stable, allowing it to be used more securely across a broader range of applications.
