So, Let’s start
Plastic packaging is ubiquitous in today’s market, but the drive for sustainability has put its environmental impact in the spotlight. While many efforts are underway to reduce plastic waste, certain applications, such as food and medical equipment packaging, still necessitate the protective qualities of plastic. To bridge the gap between functionality and sustainability, the shift from traditional oil-based plastics to bioplastics has gained momentum. These bioplastics offer lower ecological and carbon footprints but, just as importantly, they address what happens to the material at the end of its life, a crucial aspect in limiting its environmental impact.
The Key Criteria for Sustainable Bioplastics
For bioplastics to be truly sustainable, they must meet two essential criteria: recyclability and natural biodegradability. A recyclable bioplastic reduces the need for new resources, making resource use more efficient. Additionally, a bioplastic that degrades quickly and safely in the natural environment prevents it from contributing to the plastic pollution problem caused by traditional oil-based plastics.
The Scarcity of Sustainable Bioplastics
While the idea of sustainable bioplastics is appealing, very few products on the market currently meet both criteria. Even when bioplastics are recyclable, the lack of widespread facilities capable of handling them means that they can still end up in landfills or as litter. Even when they do eventually break down, some may release eco-toxic compounds, further harming the environment.
Innovative Solutions: Full Cycle Bioplastics and Polymateria
Two companies stand out in the bioplastics and circular packaging industry for offering materials that are both recyclable and environmentally friendly if they escape the waste processing stream.
Full Cycle Bioplastics: Harvesting PHA from Microbes
Full Cycle Bioplastics, a California-based startup, has partnered with Elk Packaging and Associated Labels and Packaging to create a compostable polyhydroxyalkanoate (PHA) from agricultural byproducts and food waste. PHAs, such as the one produced by Full Cycle, serve as substitutes for petrochemical multi-layer packaging found in everyday items like food and laundry detergent. What sets Full Cycle apart is that its version is not only recyclable but also biodegradable in marine environments.
The process begins with the collection of organic feedstock from various sources, including compost facilities, landfills, food processors, and large agricultural operations. This feedstock is then fermented by non-GMO bacteria, which convert it into PHA. The resulting PHA can be customized for different product applications. Full Cycle has future plans to co-locate its bacterial vats at composting plants, offering an additional revenue stream for companies that generate organic waste.
A Full Circle with Microbial Recycling
One of the remarkable aspects of Full Cycle’s process is that it enables them to take back products made with their material and feed them back to the bacteria, creating virgin PHA. This closed-loop system minimizes the need for additional resources like land and fertilizers.
Polymateria’s Programmable Plastics
Polymateria, a startup from Imperial College, has addressed a common issue with rapidly degrading plastics: the premature shortening of a product’s lifespan. They’ve developed a material with a pre-programmed lifespan, ensuring it remains functional for a specific period before decomposing. This innovation is particularly valuable for applications where product durability is vital.
Polymateria works with polyethylene, a common type of plastic. They provide a drop-in pellet that packaging manufacturers add to their resin during production. After a designated time, catalysts in the pellet trigger the plastic to break down into a wax-like substance, which attracts microbes, fungi, and bacteria for safe digestion. Notably, the process only begins after a manufacturer-set time limit, allowing the product to remain functional during the consumer’s use.
Balancing Biodegradability and Durability
Polymateria’s technology can be applied to bio-polymers as well, offering a balanced solution that allows plastics to decompose naturally while maintaining their functionality for an extended period.
Recycling vs. Biodegradability
While biodegradability is vital to limit the ecological impact of plastics that escape the waste processing cycle, recycling is often considered a more environmentally friendly option. Polymateria recognizes that biodegradability should not replace recycling. Their modified polyethylene can still be collected and recycled before decomposition begins, making it a last-resort solution to prevent plastics from harming the environment.
A Call for Informed Choices
In a world where consumers are often unclear about what “biodegradable” truly means, informing them about sustainable packaging options is essential. Clear laws and guidelines regarding the testing and marketing of bioplastics can empower consumers to select packaging materials with minimal environmental impact.
To achieve sustainable packaging, a balance between biodegradability and recyclability is crucial. Companies like Full Cycle Bioplastics and Polymateria are leading the way in providing solutions that protect the environment while meeting the needs of consumers and industries. With more informed choices and improved infrastructure, the packaging industry can continue its journey towards a more sustainable future.
