Summary
In this fascinating conversation about recycling, host Mickey Bennett sits down with eco-entrepreneur Ezekiel Setne to explore what really happens to our recyclables. The discussion reveals surprising insights about the global recycling ecosystem and its recent dramatic changes.
The conversation begins with a look at the pre-2018 recycling world, when China dominated global recycling by cleverly taking advantage of empty shipping containers returning from delivering goods to other countries. China filled them with up to 70% of the world’s recyclables, efficiently turning these materials into new products. However, this efficiency came at a cost, creating concentrated environmental damage around Chinese ports that eventually led to “superfund sites” requiring extensive cleanup.
When China banned recycling imports in 2018 through the National Sword Law, it created a crisis in the US. Ezekiel reveals how this led to several years where most recyclables ended up in landfills while new domestic infrastructure was developed.
The interview delves into the current state of different types of recycling. While the US excels at metal recycling with nearly 100% success rates, plastic recycling faces significant economic challenges. Oil companies keep virgin plastic prices so low that recycling often isn’t economically viable, resulting in only 15-20% of plastic being recycled.
In discussing the controversial topic of landfills, Ezekiel acknowledged their usefulness while explaining their long-term drawbacks as cities expand around them. These sites occupy increasingly valuable property that is potentially unstable due to methane pockets. The conversation touches on more recent concerns like microplastics, where Ezekiel notes we’re in an “awkward phase” of research where we suspect problems but don’t yet fully understand the implications.
The discussion concludes with a fascinating story about the evolution of e-waste recycling. Recyclers in India extracted the gold from electronic components, transforming what was once a waste into a precious resource worth up to $50 per pound. Throughout the interview, Mickey’s genuine curiosity and Ezekiel’s industry knowledge combine to make complex topics accessible and engaging.
Despite some sobering realities about recycling’s challenges, Ezekiel optimistically highlights how recycling continues to improve. The conversation takes listeners behind the scenes of an industry that impacts everyone but is understood by few.
