Hey everyone, FIBC
If you’ve ever worked in agriculture, chemicals, construction, or any bulk material handling industry, you’ve probably seen a FIBC—you know, those flexible intermediate bulk containers we often call “big bags.” For years, I’ve been a FIBC supplier, and one question I get more than any other is: Can FIBC actually be recycled? It’s a fair ask, especially as more and more of our clients are shifting to sustainable practices and trying to cut down on industrial waste. Today, I want to break this down not just as a supplier, but as someone who’s spent decades watching how big bags move from production to end use to the end of their lifecycle.
First, let’s get clear on what a FIBC is. Most standard FIBCs are made from woven polypropylene (PP), a thermoplastic polymer that’s tough, lightweight, and perfect for holding 500kg to 2,000kg of granular or powdered materials. Some FIBCs have liners—usually another plastic, like linear low-density polyethylene (LLDPE) or high-density polyethylene (HDPE)—or features like conductive threads for static control, which makes recycling a bit trickier. That’s a key point: not all FIBCs are the same, so their recyclability depends heavily on what they’re made of, how they were used, and their condition when they’re ready to be repurposed.
A lot of people assume that because FIBCs are made of plastic, they’re just like any other plastic bag when it comes to recycling. But here’s where that’s not the case. Regular single-use plastic bags are thin, made of film, and often contaminated with food or other residues. FIBCs are woven, thicker, and designed for repeated use (though many are single-use). The problem with recycling old FIBCs isn’t the plastic itself—it’s usually the contamination. If a FIBC held a toxic chemical, like certain fertilizers or industrial powders, even a small residual amount can make the entire bag unsuitable for recycling into new products that touch food or consumer goods. That’s a big reason why some recycling programs turn away FIBCs, but that doesn’t mean they can’t be recycled at all.
So, let’s talk about the science of FIBC recycling. Woven polypropylene is a thermoplastic, which means it can be melted down and reprocessed multiple times (though each time, the polymer chains shorten a bit, so the recycled material isn’t quite as strong as virgin PP). When we process clean, used woven PP FIBCs, the first step is collection and sorting. This is where a lot of work happens—sorting out any FIBCs made with other plastics, liners, or contaminants. Once sorted, the bags are cleaned to remove any leftover product residues, then shredded into small flakes. The flakes go through a process called “extrusion,” where they’re melted into a molten plastic, filtered to remove any remaining impurities, and then formed into pellets. These recycled PP pellets can be used to make a range of products, from new FIBCs (many suppliers, myself included, now use a mix of virgin and recycled PP for new bags) to outdoor furniture, plastic pallets, construction materials, and even automotive parts.
Conductive FIBCs, which are used for flammable materials like gasoline or explosives, have metal threads woven into the PP. Those threads are a problem for standard recycling because they can damage machinery, so they need to be removed before processing. That’s a specialized step, but it’s doable—many recycling facilities now have the equipment to extract metal threads safely. The liners too, if they’re made of a different plastic, require separation. Some recyclers will process the woven PP and the liner separately, which is why it’s important for users to report if their FIBCs have liners so sorting can happen correctly.
I’ve seen too many clients discard perfectly good FIBCs because they thought they couldn’t be recycled—and that’s a waste, both economically and environmentally. A FIBC that’s only held grain, sugar, or other non-toxic, non-contaminating materials is a prime candidate for recycling. Even FIBCs that have minor wear and tear (like small tears along the seams) can be repaired and reused multiple times before recycling, which is another huge benefit. Reusing a FIBC once or twice cuts down on waste way more than recycling it right away, so that’s a step we always encourage our clients to take first.
Now, let’s address the myths. One common myth is that all FIBCs can’t be recycled. That’s not true—clean, pure woven PP FIBCs are some of the most recyclable industrial plastics out there, as long as they’re processed correctly. Another myth is that recycled FIBC plastic is low-quality. While it’s true that it’s not as strong as virgin PP, that’s not a bad thing for many applications. Outdoor furniture, for example, doesn’t need the same level of strength as a heavy-duty FIBC, and recycled PP works perfectly for that. In fact, some studies have shown that recycled PP from FIBCs has a higher tensile strength than recycled plastic from thinner film products, because the woven structure gives the material extra durability even after reprocessing.
But there are real barriers to FIBC recycling, and as a supplier, I’ve worked with clients and recycling facilities to overcome these. One of the biggest barriers is lack of access to specialized recycling programs. Most curbside recycling programs don’t accept industrial FIBCs—they’re too large, too variable, and often contaminated. That means industrial users need to work with dedicated industrial recycling companies that handle bulk plastics. Another barrier is cost. Collecting, sorting, and processing FIBCs can be more expensive than just making new ones, especially if there’s a low demand for recycled PP. But that’s changing—more brands and manufacturers are requiring recycled content in their packaging and materials, which is driving up the market for reprocessed FIBC plastic.
We’ve also found that education is key. Many of our clients don’t know how to prepare their FIBCs for recycling. It’s not just about dropping them off—they need to empty them completely, clean out any residue, remove any liners if they’re not compatible with the main bag, and sort them by material type (standard vs. conductive, etc.). A few years back, we started including a small guide with every FIBC we sell, explaining how to reuse and recycle the bag when it’s done, and that’s cut down on the number of FIBCs we see being thrown away unnecessarily. We also work with local recycling partners to offer bulk pick-up services for our clients, so they don’t have to figure out the logistics on their own.
Let’s look at some data to back this up. The Plastics Industry Association reports that polypropylene recycling rates for industrial products are around 20% globally, and that number is growing as more facilities invest in PP processing. A 2022 study from the European Plastics Converters found that recycled PP from FIBCs has a 95% yield rate for applications like bulk packaging and construction materials, which is higher than many other plastic recycling streams. That’s a big deal—so the material itself is highly recyclable, the issue is infrastructure and practice, not the product.
What does this mean for FIBC suppliers and users moving forward? It means we need to design FIBCs with recycling in mind. That’s called “design for recycling,” and it’s something we’ve been focusing on at our company. We’re making FIBCs with fewer components, using mono-materials (so the entire bag is PP, no separate liners), and labeling them clearly so recyclers know exactly what they’re working with. We’re also partnering with our clients to create closed-loop systems—where our used FIBCs are collected, recycled, and turned into new FIBCs or other products that our clients use. That’s the circular economy in action, and it’s way more sustainable than the linear “make-use-discard” model.
I’ll be honest—there’s still work to do. FIBC recycling isn’t as simple as tossing a plastic bottle into a bin, and it won’t eliminate all industrial plastic waste. But it’s a viable, important option that more people are starting to embrace. As a supplier, it’s my responsibility not just to provide high-quality FIBCs, but to help our customers make the most of every bag, from production to end of life. That means answering their questions about recycling, providing resources to make it easy, and investing in systems that turn old bags into new, useful products.
If you’re a user who’s been wondering how to get started with FIBC recycling, or if you’re looking for a supplier that prioritizes sustainable practices, we’re here to help. We can walk you through what types of FIBCs are best for recycling, how to prepare them, and connect you with the right recycling partners.
