The Plastic-Eating Bacteria That Could Save the World

Plastic is everywhere and recycling it is harder than you think. In this episode of Climate Conversations by Rain Matter, we sit down with an Indian scientist who is using AI-powered protein engineering to develop enzymes that can break down PET plastic faster than ever before achieving 90% weight reduction in just 17 hours. From the limitations of mechanical and chemical recycling to the promise of biotechnology, this conversation explores a cutting-edge solution to one of India's and the world's biggest environmental challenges. Key Topics Covered ♻️ The Recycling Reality: Why most plastic never actually gets recycled and the specific limits of current mechanical and chemical recycling methods. 🦠 Biotechnology Solutions: How plastic-eating bacteria and engineered enzymes can break PET down into reusable monomers without the use of toxic chemicals. 🤖 The Role of AI: How AI and machine learning are being used to speed up enzyme engineering cutting millennia of traditional lab work down to mere hours. 🌍 Systemic Scaling: What systemic changes (regulation, consumer behavior, and waste segregation) are needed for enzymatic recycling to scale effectively in India.
