Many biodegradable films require industrial composting facilities to break down, which are not widely accessible in many regions. Others may degrade naturally, but this process often results in microplastics that pose a threat to wildlife, marine life, and even human health.
Bio-assimilation technology represents a groundbreaking solution to the global plastic crisis, and Precisionrap DK is at the forefront of this innovation.
This revolutionary stretch film offers a sustainable alternative to traditional plastic films, combining superior performance with environmental responsibility.
But what exactly is bio-assimilation and what does it mean for businesses looking to reduce their environmental impact?
In this article, we explore all you need to know about bio-assimilation and how it is transforming the packaging industry.
What is bio-assimilation?
Bio-assimilation is the final stage of plastic biodegradation, where the material breaks down to a molecular weight that can be consumed by living organisms. Unlike traditional biodegradable or compostable plastics, bio-assimilable materials degrade completely into harmless components, leaving no microplastics or toxic residues behind. This innovative process represents a truly sustainable solution to the plastic waste crisis.
How does bio-assimilation work?
Bio-assimilation works through a multi-step process:
- Controlled degradation: The process is engineered to begin only after a predetermined period, typically around two years, ensuring the material maintains its protective properties during its intended use.
- Molecular breakdown: Once the predetermined period is over, the plastic's molecular structure begins to break down to a weight that can be consumed by living organisms. This is often catalysed by the inclusion of specific transition metals in the plastic formulation, which act as catalysts to break the carbon-to-carbon bonds within the polymer molecules.
- Microbial consumption: Microorganisms grow as colonies on the plastic surface, adhering to it with thin appendages. These appendages secrete plastic-degrading enzymes, enabling the microorganisms to consume the broken-down polymers.
- Complete biodegradation: The material degrades entirely into biomass, water, and a small amount of carbon dioxide. This process can occur in diverse settings, including terrestrial, aquatic, and even anaerobic landfills, without requiring special conditions like oxygen or sunlight.
