Host: Elise Hu
Guest: Patricia Aymà Maldonado (biotechnologist and “bacteria trainer”), followed by an interview with TED Fellows director Lily James Olds

Overview

This episode centers around the innovative work of Patricia Aymà Maldonado, a biotechnologist who refers to herself as a "bacteria trainer." Patricia shares her story and explains how her company uses bacteria to transform industrial organic waste—such as spent yeast from beer brewing—into fully biodegradable, microplastic-free bioplastic. She discusses critical flaws in today’s plastic and recycling systems and why true sustainability requires fundamental industry change driven by science, technology, and collective responsibility.

Following her talk, Patricia joins TED Fellows director Lily James Olds for an insightful conversation about the science, challenges, and global impact of her work.

Key Topics & Discussion Points

1. Patricia’s Journey & Early Inspiration

• Personal story: Childhood illnesses caused by bacteria led to early curiosity.
• Turning point: In high school, exposure to students modifying bacteria for protein production and world hunger solutions changed her life and direction.

  "They are the most special creature on earth because they are super powerful. They just can kill you or save you in a second." — Patricia Aymà Maldonado (03:49)

2. The Real Problem with Plastics

• Not just a material issue: Plastic itself is not inherently bad; it enables countless advancements.
• Systemic issue: The problem is how it’s produced, used, and disposed of—most plastic comes from petroleum and isn't properly recycled.
• Startling facts:
  • Only 9% of all plastic is recycled.
  • Virgin plastic production rises alongside recycling, promoting an “illusion of sustainability.”
• Accountability gap: The burden of environmental responsibility has shifted unfairly to consumers.

  "It often seems that the full responsibility falls into individuals. No matter how you try to avoid single use plastics, ... it will never be enough." — Patricia (06:02)

3. Bioplastics: A True Alternative

• Definitions:
  • Bioplastic from origin: not petro-based.
  • Bioplastic for end-of-life: is biodegradable or compostable.
  • Her company’s plastic: biodegradable from start to finish.
• Model:
  • Partner with companies to take in their organic waste (e.g., beer yeast).
  • Two-stage bacteria process: one group “cooks” the waste to make it usable; the next group produces bioplastic from it.
  • On-site modular systems at partner facilities, operating 24/7.
  • Current scale: three tons of waste processed per day; 300g waste produces 1kg bioplastic.
• Product performance:
  • Behaves like traditional plastic (melting, flowing, strength, machinability).
  • Used in luxury, cosmetic, and healthcare products.

4. Environmental Benefits

• Rapid degradation:

  "If the bioplastic gets to the marine environment … in four months, it can biodegrade 90% depending on … thickness." — Patricia (09:13)

• No microplastics:

  "You cannot make microplastics with bioplastics. ... It breaks naturally … and is food for other bacteria." — Patricia (09:21)

• Circularity: Material returns to organic matter, feeding other microorganisms.

Conversation Highlights (Patricia & Lily James Olds)

5. On Being a "Bacteria Trainer"

(12:41 – 13:52)

• Patricia explains she “trains” bacteria by creating precisely tuned environments, adjusting variables like nutrients, pH, and oxygen, so they convert waste into bioplastic.

  “Bacteria don’t have brains … but they respond precisely to the conditions we create. ... In my case, I train them to transform industrial organic waste into fully biodegradable, microplastic-free bioplastics.” — Patricia (12:56)

6. Recycling’s False Promise

(13:52 – 15:42)

• Only 9% is truly recycled; the rest is incinerated, landfilled, or lost to the environment.
• Recycling degrades plastic quality, requiring more virgin (petro-based) material, perpetuating the cycle.

  "Mechanical recycling is just kicking the problem into the future. It delays the waste and it's not solving the problem." — Patricia (14:26)

7. What’s Needed: Systemic Change

(16:00 – 17:36)

• Calls for reducing problematic waste at the creation stage, not just “recycling better.”
• Pushes for industry responsibility—better materials, better design, circular economy thinking.

  "Change doesn’t happen only in our kitchens. It happens when all the industry, all the system, is accountable." — Patricia (16:57)

8. Shifting Responsibility from Individuals to Companies

(17:36 – 19:20)

• Consumers have little real choice—most products wrapped in plastic by default.

• Advocates for regulatory and social pressure on companies to switch to sustainable packaging and innovation.

  “The important thing here is not to blame the material itself, but to understand what it is designed for and ensure the end of life match with the purpose.” — Patricia (18:05)

9. The Bioplastic Marketplace & Future Growth

(19:20 – 20:46)

• Not all bioplastics are equal; origin and end-of-life properties matter.
• There will be more market alternatives in the near future, but industry adoption and scalability are the big hurdles.

10. Why "No Microplastics" Matters

(20:46 – 22:05)

• Microplastics represent “the biggest silent pollutions of all time.”

• Unlike conventional plastics that break down into persistent microfragments, their bioplastic is certified to degrade into harmless organic compounds.

  “So most conventional plastics never fully disappear … Our material … transforms into harmless organic compounds that microorganisms can naturally consume.” — Patricia (21:32)

11. Bioplastic Strength & Performance

(22:05 – 23:30)

• Dispels myth that “biodegradable” means “fragile” or “weak.”

• Bioplastic durability matches that of traditional plastic and only breaks down in proper composting conditions.

  “Biodegradable doesn’t mean that it disappears anywhere. … The important thing to understand is that biodegradation depends on the environment, not on the material's performance.” — Patricia (22:23)

12. Customization for End-of-Life

(23:30 – 24:10)

• Bioplastics can be tailored: e.g., agricultural films that compost in soil after harvest, luxury goods that only biodegrade at higher temperatures in industrial settings.

13. Challenges to Scaling Up

(26:23 – 27:26)

• Complexity grows with scale; biological and engineering consistency are difficult to maintain.

  “Scaling biotechnology is never a linear process. … When you increase volume, you get the same problems, but magnified.” — Patricia (26:38)

14. The Oil Industry’s Entrenched Power

(27:26 – 28:59)

• Existing plastic companies favor petro-plastics: price, existing machinery, and established processes create resistance to change.

• The oil/plastic industry has strong lobbying power, as seen in political inaction (ex: COP30).

  “It's easy to buy, easy to use, and the machines are adapted … so they are not willing to change because the system works like this.” — Patricia (27:53)

15. Vision for the Future

(29:50 – 31:22)

• Hopes for modular, distributed bioplastic facilities near waste sources to enable massive, global conversion of waste to material.

• Envisions a world where materials are “designed to disappear”—norm, not exception.

  “I want to see materials that are designed to disappear become the norm. … Scaling won't just mean producing more bioplastic, it will mean redesigning the entire segment of the materials economy so that things we use every day … never become pollution again.” — Patricia (30:55)

Summary & Takeaways

Patricia Aymà Maldonado’s talk and interview articulate the urgent need to address plastic pollution not through incremental consumer efforts or recycling alone, but by transforming how materials are sourced, produced, and designed. Her company’s breakthrough process—training bacteria to convert industrial waste into robust, microplastic-free bioplastic—proves that alternatives exist and can succeed at scale with the right technological and social frameworks. However, lasting change demands industry-wide accountability, consumer awareness, political will, and a bold rethinking of the world’s material economy.

Memorable final vision:

“If we get this right, scaling won't just mean producing more bioplastic, it will mean redesigning the entire segment of the materials economy so that the things we use every day … never become pollution again.” (30:55)
