New Catalyst Could Revolutionize Plastic Recycling

SEATTLE (Scrap Monster): One of the biggest barriers to effective recycling has been the need to sort plastics before processing. Now, scientists at Northwestern University may have found a breakthrough solution. According to New Atlas, researchers developed a cheap nickel-based catalyst that can recycle mixed plastic waste without the labor-intensive sorting step, potentially transforming how the world handles single-use packaging.

The catalyst works by targeting polyolefins—the most common plastics found in items like trash bags, bottles, and wraps—which make up over 220 million tons of global production each year. Currently, less than 10% of this material is recycled, largely because polyolefins are so tough to break down. By selectively cutting carbon-carbon bonds, the new process converts them into oils and waxes that can be upcycled into fuels and lubricants.

Even more promising, the catalyst operates at lower temperatures, requires less hydrogen, and remains stable when exposed to contaminants like PVC. Typically, PVC ruins recycling batches, forcing entire loads of plastic into landfills. In this case, researchers found PVC actually accelerated the breakdown process.

Tobin Marks, senior author of the study published in Nature Chemistry, explained that the innovation could make recycling “more efficient, practical and economically viable than current strategies.” Co-author Yosi Kratish added that the ability to process such chemically resistant plastics is “especially remarkable.”

With global plastic production expected to nearly double to 884 million tons by 2050, this kind of innovation could be game-changing. It not only improves efficiency but could also reduce the massive strain plastics place on ecosystems when they aren’t properly recycled.

If adopted at scale, this catalyst might finally allow recycling to catch up with runaway plastic production. It’s a hopeful step toward reducing waste, cutting Pollution, and moving closer to a truly circular economy.
