Plastics make up 8% of global waste and the issue is getting worse. Over the last twenty years, plastic production has doubled. Sadly, 90% of this plastic ends up in landfills or is burned, causing big environmental problems. But, a new scientific find might help solve this issue – bacteria that can break down and “eat” plastic.

Scientists at The University of Texas in Austin found an enzyme called FAST-PETase. This enzyme can quickly break down PET plastics, found in things like water bottles and clothes. This means plastic that takes almost 500 years to break down can now be gone in just a day with these special bacteria.

Key Takeaways

  • Plastic pollution is a big problem, with tons of plastic ending up in oceans, landfills, and nature.
  • Scientists found bacteria that can eat different kinds of plastic, which could help solve the plastic pollution issue.
  • The FAST-PETase enzyme can break down PET plastics in a day, much faster than the 500 years it used to take.
  • This could lead to better ways to manage waste and save energy now used to break down plastic.
  • Using these bacteria could help move towards a circular economy, where plastic is used and reused more.

The Scourge of Plastic Pollution

Plastic pollution is causing huge harm to our environment. Plastic waste is piling up in oceans, rivers, and on land. It hurts wildlife and pollutes soil and water. This mess can last for hundreds of years, damaging our ecosystems for a long time.

Microplastics: A Growing Concern

Microplastics, being tiny pieces of plastic under five millimeters, are a big problem. They are often eaten by sea creatures and can move up the food chain. This poses a risk to our health. Research shows microplastics in food, water, and even salt we eat, exposing us to harmful chemicals from the plastic.

  • Plastic bags are a big source of microplastics.
  • Health risks from microplastics include inflammation, endocrine problems, cancer, reproductive issues, and developmental problems.
  • Using reusable bags made from materials like cotton, mesh, or recycled fabric can cut down on microplastic pollution.

The amount of plastic pollution is huge. Over 171 trillion pieces of plastic are floating in our oceans, and this could increase by three times by 2040. The Great Pacific Garbage Patch is as big as Great Britain. This pollution hurts the environment, economy, and society.

“Plastic pollution is harming our planet, threatening marine life and human health. We need to act and find sustainable ways to solve this crisis.”

Bacteria: Nature’s Recyclers

Bacteria are key players in breaking down and recycling materials, including plastic. These tiny organisms have developed special enzymes and ways to use plastic as food. This process is called biodegradation. Researchers are looking into using these plastic-eating bacteria for bioremediation, cleaning up pollution with living organisms.

Many types of bacteria can break down and eat different plastics, like polyethylene, polypropylene, and polystyrene. They have special enzymes that cut plastic into smaller pieces. This lets them use the carbon and hydrogen for energy and nutrients.

The process of bacteria breaking down plastic has several steps:

  1. Adhesion: Bacteria stick to the plastic using special proteins or structures.
  2. Depolymerization: Bacteria enzymes break the plastic chains into smaller bits.
  3. Assimilation: The bacteria use the plastic bits as a food source, turning them into their own biomass.
  4. Mineralization: Finally, bacteria turn the plastic into carbon dioxide, water, and harmless byproducts.

How fast and well bacteria can break down plastic depends on the plastic type, the environment, and other microorganisms around them.
