A New Way to Recycle Anaerobic Adhesives Packaging

    October 11, 2016

When it comes to recycling, we generally don’t think twice about tossing grocery items like cans, bottles, boxes, and even newspapers into the proper bin so they stay out of landfills. Americans recycled 34 percent of household waste in 2013, a huge increase over the less than than 10 percent of waste that was being recycled in 1980.

Why are we recycling more? Municipal recycling programs certainly play a role. Our communities are making it easier for their citizens to recycle by providing receptacles, adopting single-stream systems and educating on the many benefits that recycling offers.

But in other facets of our lives, we completely ignore recycling because there are no systems in place. Take our well-known red Loctite® bottles, for example. They’re most often used while we’re working in facilities that likely don’t have a formalized recycling program. When they’re empty, most of them get tossed in the trash and end up in landfills – until now.

Henkel Accepted Waste

We’ve partnered with the recycling experts at TerraCycle to crack the code of recycling Loctite anaerobic bottles. It wasn’t easy, but here’s how we did it.

The New TerraCycle Adhesives Packaging Recycling Program

TerraCycle specializes in figuring out what to do with hard-to-recycle waste like potato chip bags, coffee capsules, and even laboratory waste. This was the first time, however, that they had worked on recycling adhesives packaging, so it took a bit of experimenting to find the right solution.

What happens to the waste?

Loctite bottles are made from a common type of plastic that can be easily recycled by running it through a shredder. The adhesive residue inside the bottles presented a challenge, however. Anaerobic adhesives remain liquid as long as they’re exposed to oxygen, so shredding the bottles would cause the adhesive to leak out and stick to the shredder.

The Solution

The TerraCycle team discovered that the best way to recycle our anaerobic bottles was to cure the adhesive residue first.

Once cured, anaerobics become a hard plastic, so the adhesives and the bottles can be recycled together into a blend of plastics.

This blend is shredded and pelletized, and then sold to plastic manufacturers to be made into new plastic products like garbage cans, paving stones, park benches, and outdoor furniture.

The team tried many methods to cure the adhesive including freezing and UV light, but found that the best way was heating the bottles in a convection oven.

The good news? All you have to do is drop the bottles into a collection box and send them back to TerraCycle for processing. Here’s how it works:

What Should We Turn the Bottles Into?

We want to hear your ideas! What should we turn our recycled Loctite bottles into? Let us know in the comments.

Millions of Loctite anaerobic bottles are used every year in the U.S. and Canada. What if they didn’t end up in landfills and instead were turned into something that could be used again? What if that something could be enjoyed for years to come? What if it was something functional? What if it was something artistic?

Some of the companies TerraCycle works with have recycled or “upcycled” waste into new items.

They have done things like sewing juice pouches into lunch bags:

    Hi Alyssa,

    This is good news! I haven’t seen those TerraCycle Adhesives Packaging Recycling bins at any Home Depot stores here in Montreal. Here’s hoping we’ll get them!
