One of the biggest environmental issues in our modern world is plastic, which has become integral in the manufacturing of everything from electronics to furniture. Our reliance on plastic has led to a recycling crisis: A vast amount of plastic that winds up in our recycling bins isn’t actually recyclable, and ultimately winds up in landfills.Large companies have committed to reducing plastic packaging and cutting back on waste. But there’s still no good way to scale up the removal of plastic that already exists. Waste-eating bacteria and enzymes have been shown to work in lab settings, but the scale-up process has a long road ahead.Judith Enck, former EPA regional administrator and founder of the organization Beyond Plastics, has dedicated her career to advocating for making plastics more recyclable and keeping toxic chemicals out of the manufacturing process. She joins guest host Maggie Koerth to talk about why plastics are such a difficult environmental issue to solve, and what makes her feel hopeful this Earth Day.Transcripts for this segment will be available the week after the show airs on sciencefriday.com.
