Solving the Plastic Problem: Current Enzymatic Breakthroughs vs. Biodegradable Plastics

When it comes to the world's plastic problem, many have pinned their hopes on biodegradable plastics as a solution. However, recent advancements in the field of enzymatic breakdown of plastics have revealed a more promising approach. Companies like Bacardi have taken steps in creating biodegradable plastics, but these efforts might be overshadowed by new discoveries in enzymatic technology.

While biodegradable plastics have been available for nearly two decades, they have not been widely adopted due to their higher costs and inferior performance compared to non-biodegradable plastics. Additionally, the microplastics problem remains a significant challenge, as these tiny particles can persist in the environment and even be found in some of the deepest ocean regions, such as the Mariana Trench.

The Advancement in Enzymatic Breakdown

Scientists and researchers have made significant progress in discovering and enhancing enzymes that can degrade plastics. These enzymes, found in microbes, worms, and mushrooms, are capable of breaking down plastics into organic compounds or monomer particles. Companies like French firm Carbios have already started building industrial facilities to harness these enzymes on a large scale.

The process of breaking down plastics using enzymes can be completed in a matter of hours, compared to the weeks or even months required for known biodegradable plastics. This rapid breakdown process makes the technology highly efficient and commercially viable forlarge-scale recycling operations. These advancements represent a significant leap forward in combating the plastic waste problem.

Biodegradable Plastics: A Brief History

There is no one-size-fits-all solution when it comes to biodegradable plastics. Since the late 1880s, biodegradable plastics have been a topic of research, though they were not commercialized until 1983 when a UK company, ICI, patented a viable process. Biodegradable plastics have been around for nearly two decades but have not achieved widespread adoption due to their higher costs and limitations in terms of performance and shelf life.

Consumer Impact and Call to Action

Consumers can play a crucial role in driving change by encouraging companies to adopt more sustainable practices. For example, Billabong, a surfwear company, has shifted to manufacturing shorts made from recycled PET plastic bottles, showcasing that innovative practices can indeed make a difference. However, the issue of existing microplastics is more complex, as these tiny particles have infiltrated even the deepest parts of the ocean.

Reducing the impact of microplastics is a multifaceted challenge, one that requires a combination of technological advancements and consumer action. By supporting companies that implement eco-friendly practices, consumers can encourage the industry to move towards a more sustainable future. Ultimately, the key lies in the collective effort and innovative solutions that can help mitigate the plastic problem.

Key Takeaways:

Enzymatic breakdown of plastics is a new and promising solution that can help reduce plastic waste more rapidly. Biodegradable plastics have been around for nearly two decades but face challenges in cost and performance. Consumer support and industry innovation are essential in addressing the plastic problem and reducing microplastics in the environment.
