00:00The battle against plastic. A simple metal could be the key.

00:05We are drowning in plastic. From milk bottles to trash bags, polyolefins dominate our daily lives,

00:12making up almost two-thirds of global consumption.

00:15But they have a serious problem. They're incredibly difficult to recycle.

00:20Their strong carbon-carbon bonds are nearly unbreakable.

00:25Making recycling rates for these plastics woefully low, often less than 10%.

00:30Current methods, like melting and shredding, are expensive and require meticulous sorting,

00:36while others consume a massive amount of energy.

00:39But what if the solution was much simpler?

00:43Scientists at Northwestern University have found an answer, and it relies on a common and economical metal.

00:49Nickel day.

00:50They have created a new recycling process that uses a nickel-based catalyst to selectively break down polyolefin plastics.

00:58Instead of converting them into low-quality pellets,

01:02its method transforms plastic waste into high-value liquid oils and waxes,

01:06which can be used to create products like lubricants, fuels, and candles.

01:12This breakthrough is a giant leap forward.

01:15First, it bypasses the laborious process of pre-sorting.

01:19The catalyst works directly on large volumes of unsorted plastic waste,

01:24eliminating one of the biggest logistical and economic hurdles in recycling.

01:29It's also incredibly efficient and economical.

01:33The process is carried out at a temperature 100 degrees lower,

01:37and uses half the hydrogen gas pressure of other methods.

01:40And because it uses nickel-an, abundant and affordable metal,

01:45instead of rare and costly metals like platinum,

01:49it is much more scalable.

01:52But the story gets even more remarkable.

01:55One of the biggest villains in the world of plastic recycling is polyvinyl chloride, or PVC.

02:01This polymer is so toxic that, when heated,

02:05it releases a corrosive gas that ruins any recycling process.

02:10The researchers expected PVC to be a problem for their new nickel catalyst.

02:14But to their surprise, the exact opposite happened.

02:18The presence of PVC not only didn't ruin the process,

02:22but it actually accelerated the catalyst's activity and improved its performance.

02:27This totally unexpected result suggests that this method could tackle

02:31even the mixture of plastic waste that is currently considered impossible to recycle.

02:37This breakthrough represents a promising path forward,

02:41offering a process that is not only more efficient and sustainable,

02:45but also economically viable.

02:47It could transform our global plastic problem into a valuable resource.
