Innovative Startup Harnesses AI to Recycle Plastic through Engineered Enzymes

Turning Plastic Waste into Reusable Materials with AI-Enhanced Enzymes

A pioneering startup, known as Protein Evolution, has leveraged artificial intelligence to engineer novel enzymes capable of breaking down plastic materials and polyester fabrics that often end up in landfills. Their goal is to repurpose this waste into new materials.

With a mere 9% of plastics being recycled globally, there’s a vast majority that never gets repurposed. Protein Evolution is targeting the remaining 91% of discarded plastics by using enzymes crafted with the aid of artificial intelligence. The startup is effectively responding to the challenge of recycling plastics that are traditionally difficult to process.

Evidence of enzymes’ ability to decompose plastics has been well-documented. Through leveraging AI technology, Protein Evolution is pioneering a path towards a more sustainable and economically feasible recycling process. This innovative approach could revolutionize the way we handle plastic waste, transforming an environmental challenge into an opportunity for material regeneration.

Key Challenges and Controversies:

1. Scalability: One of the most significant challenges for technologies like the ones developed by Protein Evolution is scalability. Enzymes that work well in a lab setting may not perform effectively on an industrial scale, where vast amounts of plastic need to be processed.

2. Cost-Effectiveness: The cost of implementing AI-engineered enzymatic recycling processes needs to be competitive with conventional ones. High costs may hinder the widespread adoption of such innovative methods.

3. Purity Requirements: Recyclable plastics often need to be relatively pure and free from contamination. Ensuring a highly pure input stream can be challenging, thus impacting the efficiency of enzymatic recycling.

4. Environmental Impact: While the intention is to reduce plastic waste, there must be consideration for the environmental impact of the enzymes themselves. Questions about what happens to these enzymes after they break down the plastics and whether they introduce any secondary environmental issues are important.


1. Improved Recycling Rates: Enzymatic recycling could significantly increase the proportion of plastic waste that is recyclable, thereby reducing landfill usage and pollution.

2. Energy Efficiency: Typically, enzymatic processes require less energy than traditional mechanical and chemical recycling methods, making them more sustainable.

3. Precise Breakdown: Enzymes can be engineered to target specific types of plastic, allowing for a more selective and efficient breakdown process.


1. Development Time: Developing and optimizing enzymes with AI is a time-consuming process that involves extensive research and trial-and-error.

2. Limited Range: The current enzymes are likely to be effective for certain types of plastics only, possibly requiring different enzymes for different plastics.

3. Regulatory Hurdles: New technologies often face regulatory challenges, which can delay implementation and increase costs.
