If you’ve ever wandered the aisles of an electrical supply warehouse, you know the drill: spools of primary wire, bundles of thick power cables, and stacks of components that make the whole system work, but never get the same spotlight. As someone who’s spent 12 years in the game as a supplier of those “no one talks about” cable accessories—think cable glands, strain reliefs, terminal lugs, cable ties, and those tiny but critical sealing grommets—I get the question all the time: Can other cable accessories be recycled? Other Cable Accessories
For years, I’d fumble through a half-answer, mostly because the industry narrative was fixated on big-ticket cables and wiring harnesses. I’ve sat through trade shows where sustainability was framed as a problem for electrical engineers and big infrastructure projects, not the guy who sources 500 black nylon cable ties and brass gland fittings for a small commercial electrician’s crew. But about three years ago, we started getting notes from clients: a municipal construction company that wanted to cut its landfill waste, a renewable energy installer aiming for a net-zero project score, even a few residential electricians who were tired of throwing out perfectly good, unused accessories because they didn’t know what to do with them. That’s when I dug in, talked to our own product testing team, partnered with a local recycling co-op that works with electrical components, and realized the answer isn’t a simple yes or no—it’s nuanced, dependent on the material, the condition, and how you process these tiny, often-overlooked parts.
First, let’s clear up what we’re actually talking about here. When I say other cable accessories, I’m not referring to the heavy, insulated power cables that make up the bulk of wiring jobs. These are the complementary parts: the nylon cable ties that hold bundles in place, brass or aluminum cable glands that secure cables to enclosures, tin-plated copper terminal lugs that connect wires to breakers, silicone rubber sealing grommets that keep moisture out, and even the small plastic junction box gaskets that prevent dust from getting inside electrical cabinets. Many of these are made from a mix of materials, which is why recycling myths run rampant. People assume anything with metal is too contaminated, or that small plastic parts are just too insignificant to have a recycling stream. Neither is true.
Let’s start with the most common category: thermoplastic accessories, which make up about 60% of the parts we supply daily—think nylon cable ties, polypropylene junction box gaskets, and PVC sealing grommets. For a long time, small thermoplastic parts were seen as a contamination risk for recycling streams. A single tiny nylon tie mixed into a batch of plastic bottles could ruin an entire load, right? That was the old problem. But here’s what’s changed: modern recycling facilities have developed small-particle sorters, using near-infrared (NIR) technology that can identify specific plastic polymers down to the size of a dime. We worked with our local recycling partner in Ohio to test this last year, sending in a 50-pound bag of unused black nylon cable ties that a client had brought back from a job site. The sorters separated them from a mixed plastic batch with 92% accuracy, and the resulting recycled nylon was used to make new industrial fasteners—parts not that different from the ones we supply. The catch? It has to be clean. No leftover adhesive, no exposure to heavy chemicals, no cracks or fraying from being left out in the elements. Unused, new-in-package accessories? They’re ideal. Even slightly used ones, as long as they’re not corroded or soaked in construction site grime, can be processed through this stream.
Then there are the metal accessories, which make up most of the rest: brass cable glands, copper terminal lugs, aluminum grounding lugs, and steel lock washers used to secure fittings. For metal parts, the question isn’t really “can they be recycled?”—it’s “are we making it easy for people to do it?” Metal recycling is one of the most efficient, lowest-emission industries around; recycling brass uses 90% less energy than producing new brass from ore, for example. But the barrier here is that metal cable accessories are often small, easy to lose, and mixed in with other scrap metal at job sites, so workers tend to throw them in the general waste bin. That’s why we started a small take-back program for our commercial clients last year: we supply pre-labeled buckets for job sites to collect used metal glands and lugs, then we ship them to a metal reclaimer that specializes in electrical components. Last quarter alone, we took back 1,200 pounds of brass glands and copper lugs from contractors in the Midwest, none of which would have been recycled otherwise. The only caveat here is corrosion: if a brass gland has been exposed to saltwater or chemical residue from a construction job, it can contaminate a batch of pure brass, so those are best kept separate from clean, unused or lightly used parts.
Now, the trickiest category: mixed-material accessories. Some of our parts are made of two or more materials bonded together, like a nylon cable tie with a stainless steel locking bar, or a rubber grommet pressed into a plastic mounting flange. These have always been the black sheep of the recycling world, because separating the materials by hand is labor-intensive, and automated sorters haven’t been able to distinguish them until recently. That said, recent advances in mechanical recycling, specifically a process called “shred and sort with density separation,” have made this possible. We tested a batch of mixed cable ties and grommets last year, sending them through a shredder that breaks them into 1-inch pieces, then uses air and water to separate the lighter plastic/rubber pieces from the heavier metal components. The yield was about 85% reusable materials, with the small leftover fraction going to a specialized waste-to-energy facility that doesn’t release harmful toxins from that type of mixed plastic. It’s not perfect, but it’s a huge step up from sending all of it to a landfill.
I’ll be honest, though—recycling other cable accessories isn’t as simple as tossing them in your curbside bin. Curbside recycling programs rarely accept small electrical accessories, because most are too small to be sorted by standard machinery and are seen as “contaminants” for larger plastic loads. That’s why as a supplier, we’ve had to adapt. A lot of our clients—from small residential electricians to large municipal construction firms—don’t have access to specialized recycling streams for these parts, so that’s a gap we’re trying to fill. We’ve also learned that the biggest barrier isn’t technology or capability—it’s awareness. Earlier this year, we surveyed 200 electricians who buy our accessories, and only 12% said they knew that cable glands and terminal lugs can be recycled, even in a specialized stream. That’s the work I’m focused on now, not just selling parts, but teaching the people on the job site how to keep usable materials out of landfills.
There are still challenges, of course. For one thing, some lower-quality accessories are made from contaminated plastics or coated with heavy metals to cut costs—those parts can’t be recycled, because the contaminants ruin batches of good material. That’s why we’ve focused on sourcing our accessories from manufacturers that use virgin, pure polymers and non-toxic metal coatings, not just because they last longer, but because they’re recyclable. Another challenge is the global recycling infrastructure; while North America and Europe have well-developed streams for these parts, many smaller markets don’t, which is something the whole industry is working to address.
I’ll leave you with a story that stuck with me a few months back. A client who runs a small electrical contracting business in Detroit reached out saying he’d been throwing away hundreds of used cable ties every month, until he found our take-back program. He told us that last quarter, he saved $120 on landfill fees, because he didn’t have to pay for the bagged plastic waste, and he got a small credit for the brass glands he sent back. That’s the kind of win we’re after: turning something that was just trash into a small, meaningful part of a more sustainable job site.
So to answer the original question: yes, most other cable accessories can be recycled. It just takes a little bit of knowledge, the right partners, and a willingness to look beyond the big, flashy cables that everyone talks about. As someone who’s been in this industry for more than a decade, I’ve seen how quickly sustainability has moved from a nice-to-have to a non-negotiable, especially as more clients ask for greener practices and regulations push businesses to cut their waste. We’re not perfect—no one in this sector is—but we’re making progress, one cable tie and gland at a time.
