The Steel in an IBC Cage
Every composite IBC tote contains between 30 and 55 pounds of steel in its tubular cage frame, depending on the manufacturer and model. Most cage steel is mild carbon steel (ASTM A36 or equivalent) with a hot-dip galvanized or electro-galvanized coating to resist corrosion. Premium manufacturers like Schutz and Mauser use heavier gauge tubing with thicker galvanizing for longer service life, while economy-grade totes may use lighter-gauge steel that is more prone to rust and deformation.
When an IBC reaches end of serviceable life — whether due to a damaged HDPE bottle, an expired UN certification, or simple wear — the steel cage has typically outlasted the plastic components significantly. A cage that is structurally sound but attached to a cracked bottle still contains all of its original steel value, and that value can be recovered through the scrap metal recycling system.
Scrap Value: What Is an IBC Cage Worth?
The scrap value of an IBC cage fluctuates with steel commodity prices, which are themselves tied to global demand from construction, automotive manufacturing, and infrastructure sectors. As a rough benchmark, a 40-pound steel cage at a scrap price of $0.12 to $0.18 per pound (a typical range for unprepared ferrous scrap in the Mountain West) is worth approximately $5 to $8 at the scrapyard.
That may not sound like much per unit, but scale matters. An industrial operation that cycles through 500 IBC totes per year generates 20,000 to 27,500 pounds of cage steel — a quantity that starts to represent meaningful scrap revenue and, more importantly, a meaningful diversion of steel from landfill. At 40 pounds per cage and 500 cages, that is 25,000 pounds of steel that gets melted and reborn rather than buried.
Galvanized steel — which is what most IBC cages are made from — commands a slightly lower price per pound at most scrapyards than clean bare steel, because the zinc coating must be removed during the steelmaking process. However, the zinc itself is captured and recycled in the electric arc furnace process, so it is not wasted.
How Steel Is Recycled: From Cage to New Product
Once an IBC cage arrives at a scrapyard, the recycling process is relatively straightforward compared to the HDPE recycling process. Steel is one of the most recyclable materials on earth — it can be melted and reformed indefinitely without any degradation in quality, which is why the global steel industry currently recycles approximately 83% of all steel produced.
The IBC cage is first inspected for non-steel components — bolts, brackets, and plastic insert pieces that need to be removed before melting. The cage is then baled or sheared by heavy equipment to reduce its volume for transport to the steel mill. At the mill, the scrap is fed into an electric arc furnace (EAF), which uses powerful electric arcs to melt the steel at temperatures above 2,900°F. The molten steel is then refined, alloyed to specification, and continuously cast into billets, slabs, or blooms that go on to become rebar, structural beams, automotive parts, or new steel tubing.
Producing a ton of new steel from scrap in an electric arc furnace uses approximately 75% less energy than producing the same ton of steel from iron ore in a blast furnace. It also eliminates the mining, sintering, and coking steps entirely.
Environmental Benefits of IBC Cage Recycling
The environmental case for recycling IBC cage steel is compelling. Compared to primary steel production from iron ore, recycled steel production via the EAF route generates approximately 58% fewer greenhouse gas emissions per ton of output. It also uses no coking coal (a major source of air pollutants in blast furnace operations), generates less slag waste, and requires no new mining of iron ore or limestone.
For the steel in a single IBC cage, recycling rather than landfilling avoids roughly 50 to 80 pounds of CO₂-equivalent emissions. Across the millions of IBC cages that reach end of life globally each year, this adds up to hundreds of thousands of metric tons of avoided emissions — a contribution that is easy to overlook but genuinely meaningful at scale.
Creative Reuse Before Recycling
Before any IBC cage goes to the scrapyard, it is worth considering whether it has a second life as a useful object. IBC cages stripped of their bottles are popular as:
- Garden trellises and tomato cages — the grid spacing is ideal for supporting climbing plants.
- Security enclosures for outdoor equipment or stored materials.
- Compost bin frames when fitted with wire mesh or shade cloth.
- Livestock pen dividers on small farms and homesteads.
- Gabion basket forms filled with rock for retaining walls or landscaping features.
The hierarchy of environmental responsibility for any material goes: reduce, reuse, then recycle. A cage that serves another useful purpose before it reaches the scrapyard represents an even better environmental outcome than immediate recycling — it displaces whatever product it replaces (trellis materials, compost bins) and still gets recycled at the end of its extended useful life.
At Salt Lake IBC, we work with local farmers, gardeners, and small businesses to find creative reuse applications for IBC components before routing them to recycling. Contact us if you are looking for bare IBC cages for a project — we often have them available at very low cost or free for local pickup.
