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.
