Hey there, thanks for stopping by! If you’ve ever worked in marine construction, aquaculture, or even offshore energy, you’ve definitely crossed paths with Other Pipe Float—those unassuming, often overshadowed floats that keep pipelines, cables, and aquaculture lines afloat. I’m one of the folks who supplies these guys, and over the years, I’ve had way too many customers ask me the same thing: “Can Other Pipe Float even be recycled?” It’s such a common question, and honestly, it’s one I’ve dug into deep because, let’s be real, sustainability isn’t just a buzzword anymore—especially when we’re talking about gear that spends its whole life getting tossed around in saltwater and sun. Other Pipe Float
First off, let’s get on the same page: what actually is Other Pipe Float? A lot of people lump all pipe floats into one bucket, but these are the ones that aren’t the big, branded, high-profile ones—usually the mid-range to economy floats, made from different plastic blends, sometimes with metal fittings, and built for specific niche uses. They’re not the flashy showstoppers, but they’re workhorses. I’ve seen them used for everything from fish farm feed lines to temporary pipeline crossings during coastal projects. And because they take a beating—salt, UV rays, rough tides—they don’t last forever. A 5-year-old float that’s been sitting in the sun all day every day isn’t going to look the same as a brand new one, and that wear and tear makes people wonder if recycling is even possible.
Let’s cut to the chase: yes, Other Pipe Float can be recycled, but it’s not as straightforward as dropping a water bottle in your curbside bin. And that’s where a lot of confusion comes in. I’ve had customers who tried to toss their old floats at a local recycling center and got turned away, and others who thought they had to send them to a fancy offshore incinerator (which is a whole other can of worms). So what’s the real story here?
First, the material is the biggest factor. Most Other Pipe Float is made from polyethylene (PE)—specifically high-density PE (HDPE) or low-density PE (LDPE). HDPE is the sturdier stuff, which is why it’s used for floats that take heavy hits, and it’s super recyclable. But here’s the catch: once PE is exposed to saltwater and UV light, it breaks down into something called “photo-oxidized PE.” It’s still plastic, but its molecular structure is altered, which means it doesn’t melt as cleanly as new PE. That doesn’t mean it’s un-recyclable—it just means it needs a specific kind of processing.
Then there are the add-ons. A lot of Other Pipe Float has metal inserts for attaching lines, straps, or pipelines. Those bits are usually steel or aluminum, and you can’t just toss them in a plastic recycling bin. You have to separate them first. If a recycling center tries to process plastic floats with metal still attached, it can damage the equipment. I’ve learned this the hard way—last year, a customer sent back a pallet of old floats without pulling the metal bolts, and the recycling plant had to shut down a line for two hours to clear the debris. Total mess for everyone involved.
So what’s the actual process that works? From what I’ve worked with and researched, it goes like this: first, you collect the old floats, separate them from any non-plastic parts (metal, rubber gaskets, even leftover rope), and sort them by plastic type. Wait—most Other Pipe Float is PE, but sometimes you’ll get a mix with PVC, which is a whole different ballgame. PVC is harder to recycle, and burning it releases toxic fumes, so you have to keep that separate. Once sorted, the PE is shredded into small flakes, washed to get rid of salt, dirt, and any barnacles that have grown on the float over the years (gross, I know—shredding barnacle-covered plastic is not my favorite part of the job), and then it’s melted down in a controlled environment. Because it’s photo-oxidized, you can’t make new bottles or food-grade plastic out of it, but you can turn it into things like plastic lumber, fence posts, or even new, less critical pipe floats. It’s not closed-loop recycling (making the same product over again), but it’s still recycling—diverting tons of plastic from landfills and oceans.
Now, let’s talk about the roadblocks. The biggest one is access to the right recycling facilities. Most curbside recycling programs don’t take large, bulky plastic items like pipe floats. They’re too big, and most small centers don’t have the equipment to process them. That’s why a lot of people end up throwing them in the trash, which is basically a death sentence—plastic in landfills can take hundreds of years to break down, and if it makes its way into the ocean, it becomes microplastic, which is terrible for marine life. I’ve seen first-hand what that looks like—floats that’ve been washed up on beaches, covered in seagrass, with little crabs climbing on them, but eventually, they break down into tiny bits that fish eat. It’s not something I want my gear contributing to.
Another roadblock is cost. Recycling these floats isn’t cheap. You have to pay for collection, transportation, sorting, and processing. For small businesses or individual contractors, that extra cost might not fit into their budget. I get it—when you’re already dealing with the cost of new gear, the last thing you want to do is pay to recycle old stuff. But here’s the thing: if you don’t recycle, you’ll probably end up paying for disposal, and that’s often more expensive anyway. Plus, more and more clients are asking about sustainable practices these days. I’ve had a few big aquaculture companies tell me they’ll only work with suppliers who have a take-back or recycling program for old gear. It’s become a selling point, not just a nice-to-have.
Wait, but can all Other Pipe Float be recycled? Let’s be honest—no. If a float is so beat up that it’s cracked, chipped, or has been sitting in a landfill for 10 years, it might not be worth recycling. Or if it’s made from a mix of plastic that can’t be separated, it’s probably best to dispose of it properly (not just toss it in the woods, please). But most of the time, if the plastic is still intact enough to hold its shape and hasn’t completely crumbled, it’s recyclable. I’ve worked with a couple of facilities that accept used pipe floats, and they can process up to 85% of the material, which is way better than sending it to a landfill.
Here’s something I’ve been testing lately: a take-back program for my customers. It’s still in the early stages, but I offer to pick up old Other Pipe Float orders from clients who buy new ones from me. I work with a local recycling company that specializes in marine plastic, and they handle all the sorting and processing. I charge a small fee for the pick-up, but I waver it if the order is big enough. So far, it’s been a hit. One of my regular clients, a coastal construction company, has cut their waste from pipe floats by 90% since we started this program. They even told me they’ve saved money because the disposal fees they used to pay are way higher than the small pick-up fee I charge. It’s a win-win, right?
Another thing that’s changed the game is new technology. A few years ago, recycling photo-oxidized PE was really hit or miss. The melted plastic would be brittle and weak, so it was only good for low-stress items. But now, some facilities are adding a small amount of new PE to the mix when they process the old stuff, which makes the final product stronger and more durable. That means the recycled plastic can even be used for new pipe floats—well, not the heavy-duty ones, but definitely the mid-range ones. It’s not 100% closed-loop, but it’s as close as we’ve gotten so far.
I also want to address the elephant in the room: some people say that recycling plastic isn’t worth it, that it’s better to just switch to other materials. And I get that—there’s a lot of talk about moving away from single-use plastic and switching to metal or wood. But here’s the thing: Other Pipe Float is built to be in saltwater for years. Metal floats corrode, especially in saltwater, which is way worse for the environment than plastic. Wood rots, and you have to treat it with chemicals to make it last. Plastic, even when it’s recycled, is still a better option for longevity. And if we can recycle that plastic instead of making new plastic, that’s a big win for reducing carbon emissions. Making new HDPE uses way more energy than recycling old PE—like, I think it’s something like 70% less energy? Don’t quote me on the exact number, but it’s a ton. So even if it’s not perfect, recycling pipe floats is better than the alternative.
Now, let’s talk about what you can do if you have old Other Pipe Float that needs to be disposed of. First, check with the supplier you bought from. A lot of suppliers (like me, actually) have take-back programs or partnerships with recycling facilities. Second, don’t just toss them in your regular recycling bin. Call your local waste management company and ask if they have a bulk plastic recycling program. If not, look for specialized marine plastic recycling facilities—most coastal areas have them now. Third, if you’re handy, some people repurpose old pipe floats. I’ve seen them turned into garden planters, buoy markers for personal boats, even outdoor seating. It’s not recycling in the strict sense, but it’s diverting them from the landfill, which counts for something.
Here’s the thing I want you to take away from this: Other Pipe Float isn’t just disposable gear. It’s a product that’s been used to keep projects running, farms afloat, and infrastructure in place, and it doesn’t have to end up as pollution. Can it be recycled? Yes, but it takes a little extra effort—sorting, separating, using the right facilities. It’s not as easy as tossing a soda can in the bin, but that’s because these are bulky, heavy-duty products that have a job to do. As someone who supplies this stuff, I’m not just selling floats—I’m trying to make sure the whole lifecycle of the float is as sustainable as possible.
If you’re a contractor, aquaculture farmer, or anyone who uses Other Pipe Float and has old units sitting around taking up space, or if you’re looking for new, more sustainable options for your projects, I’d love to chat. We can work on a take-back plan, figure out how to recycle your old gear, or even talk about new floats made from recycled materials. It’s not just good for the planet—it’s good for your business too, because more and more clients are prioritizing sustainability these days.
Floating Dock At the end of the day, we all have to do our part to cut down on waste, and that includes the gear we use every day. Other Pipe Float doesn’t have to be a blip in the ocean or a pile in a landfill. With a little effort, we can keep those floats working, even after their primary job is done.
