[ES] Este proyecto se centra en el diseño y caracterización de un biofilm plástico a partir de sustancias vegetales como la celulosa de cáscara de almendra y el almidón, extraído de la tapioca. El objetivo, es desarrollar un material bioplástico ecológico que sea puramente natural y tenga prioridades mecánicas para que se degrade fácilmente, de forma natural, después de su uso. Este material, ha sido desarrollado usando el método de fundición a partir de almidón de tapioca nativo, junto con la adición de sustancia de cáscara de almendra. Han sido plastificados con glicerol y reforzados con un endurecedor biodegradable.

[EN] This research focuses on the design and characterization of a plastic biofilm from plant
substances such as almond shell cellulose and starch extracted from tapioca.
The objective is to develop an ecofriendly bioplastic material that is purely natural and
has mechanical priorities so that it degrades easily after use in a natural way. This material was
produced by the casting method from native tapioca starch, together with the addition of
almond shell substance. They have been plastified with glycerol and reinforced with a
biodegradable hardener.
The work process consisted of conditioning the tapioca chips to extract the starch, and
also to make a traditional almond shell powder, to be plasticized with glycerol in various
concentrations and gradually adding quantities of these last to improve the properties of the
material. In order to meet the objectives of this study, we retained a glycerol rate of 30% (g/g
of dry starch and almond shell powder), which would facilitate the shaping and handling of the
bioplastic.
The reinforcing material used during this project (Epoxy hardener) has a definite
influence on the appearance and the mechanical properties of the material. Indeed, the threshold
retained is 1/8 (g/g of starch and almond shell powder), beyond this threshold, the plasticization
is not easy at the retained glycerol rate. The hardener used further increases the hardness of the
material, which allows us to limit its content in the solution to 0.05ml (for 4g of starch and 2g
of almond shell powder) in the formulations of our analyses.
Various characterization tests of the plastic biofilms must be carried out, including
solubility, durability, impermeability and biodegradability. The material developed must meet
the above characteristics. In order to obtain a sustainable and eco-responsible material that can
replace plastic in certain areas. This product is like a solution for the current problems we face,
we are looking for a new lifestyle and we are considering a new approach to the materials we
are using, for our well-being and for the environment
