Bioplastics: Resistance and Sustainability

Today, we are here to demonstrate the possibilities of our material, not only in the fashion sector but in the industry at large. Bioplastics are not inherently water or fire-resistant by nature. In fact, conventional bioplastics tend to be sensitive to moisture and degrade easily. For a bioplastic to be water-resistant or fire-retardant, it is necessary to modify its properties through the incorporation of reinforcements and specific chemical processes. In our case, we achieve this advanced performance without altering the essence or the sustainability goal of our product.

 

1.      Water Resistance

 

Most bioplastics are hydrophilic (they attract water), which causes them to swell or dissolve. To improve their resistance, we employ the following strategies:

 

·         Structural reinforcements: We incorporate plant-based nanomaterials that act as reinforcements, creating a dense and compact network that effectively blocks moisture from penetrating the material's matrix.

·         Cross-linking agents: To ensure optimal stability against moisture, we use cross-linking treatments that seal the material's structure, preventing premature degradation from water contact.

·         Combination with other biopolymers: Our polymerization process transforms renewable organic carbon into a highly cohesive molecular structure, achieving a material that combines advanced architecture with the sustainability of a biogenic origin.



 

2.      Fire Resistance

 

To guarantee high-performance fire-retardant properties, the material has been developed under an advanced thermal stability design, achieving autonomous behavior against fire that ensures structural integrity without compromising its sustainability:

·         Thermal stabilization: The material possesses an intelligent reaction capacity: when exposed to extreme heat, it integrates mineral stabilizers that provide superior fire resistance without losing its biological essence.

·         Organic additives: We use naturally-derived compounds that act by interrupting the chemical combustion reaction in the gas phase, helping to self-extinguish the flame.

·         Molecular structure design: The material is designed with a chemical structure that is intrinsically heat-stable, which reduces the release of flammable gases.

 


It is important to highlight that the current challenge in materials science is to achieve the perfect balance: creating bioplastics that last as long as necessary during their use and that, at the end of their useful life, remain environmentally friendly. Our experience demonstrates that durability and biodegradability are not opposing concepts. The secret lies in the engineering of the molecular structure, so that the added components do not permanently block natural decomposition processes, but only temporarily retard them during the product's useful life.

 

How is biodegradability maintained?

 

For a bioplastic to remain biodegradable after receiving resistance treatments, the following approaches are applied:

·         Use of biocompatible additives: Instead of using persistent synthetic chemicals, additives derived from the same nature are used. Because these materials are organic, they are recognized and digested by microorganisms under composting conditions.

·         Design of "detachable" additives: Cross-linking agents are sensitive to specific composting conditions (such as pH levels or high humidity), allowing the structure to weaken when its protection is no longer required.

·         Fillers based on renewable organic carbon: When thermal stabilizers are used, concentrations are adjusted so as not to alter the soil chemistry, allowing the bioplastic matrix to decompose completely.
