Aluminium Can Baling: Processing Metal Recyclables on Site

By:     Kieran Donnelly

Aluminium can baling turns one of the most valuable recyclable materials in commercial waste into a straightforward revenue stream. Aluminium’s intrinsic metal value means that clean, segregated can bales command higher per-tonne prices than almost any other dry recyclable stream. A tonne of clean aluminium UBC (used beverage cans) bales is worth £700 to £1,200 at current market prices, compared to £80 to £150 for clean cardboard and £30 to £80 for LDPE film. The market for baled aluminium cans is well-developed and consistently liquid; the challenge is to accumulate sufficient clean volume and manage it cost-effectively before baling.

Commercial waste is generated in large volumes across the hospitality sector, stadiums and arenas, food service operations, vending machine operators, and offices. A busy pub or bar consuming 500 cans per week, a cinema operating 20 screens, a large office canteen, and a festival venue all generate significant can waste streams in both volume and market value.

The difference between managing that waste stream properly and throwing it into a general skip is substantial when the material value is this high. Aluminium can be baled at source, with clean segregation and consistent bale quality, captures that value directly rather than surrendering it to a mixed recycling contractor whose sorting and processing costs will absorb much of what the material is worth.

Why Aluminium Has Such High Recycling Value: Aluminium Can Baling

Aluminium recycling is one of the most energy-efficient recycling processes in commercial use. Recycling aluminium uses approximately 95% less energy than producing primary aluminium from bauxite ore. This energy saving is so large that aluminium producers actively purchase scrap aluminium at prices that reflect this avoided energy cost. The result is a genuine, liquid market for aluminium scrap that pays commercial prices rather than accepting material as a favour to generators.

UBC (used beverage can) aluminium is a particularly clean grade: the alloy composition of beverage cans is consistent and well-characterised, making it easy for aluminium smelters to process without the sorting and analysis required for mixed scrap aluminium. This consistency commands a price premium over mixed aluminium scrap, making UBC one of the most straightforward scrap metal streams to sell.

Baling Equipment for Cans and Metal Recyclables

Aluminium cans compact extremely well under hydraulic pressure. A UBC baler produces dense, stable can bales that maximise the weight per container load and therefore the transport efficiency of the recycling supply chain. Most vertical balers designed for cardboard can also bale cans, but dedicated can balers or balers with adjustable die settings produce denser, more consistent can bales.

 Gradeall’s can baler is specifically designed for aluminium and steel can baling at commercial volumes, producing consistent bales suited to the scrap metal market. For operations baling cans alongside other recyclable streams, Gradeall’s G-Eco 500 vertical baler handles multiple material types with appropriate settings, providing a multi-stream solution for operations with diverse recyclable waste.

Operational Management for Maximum Can Revenue

Getting maximum revenue from aluminium can recycling requires three operational disciplines: keeping the can stream clean and free from contamination, ensuring cans are separated from other materials before baling, and managing the storage and collection of bales to avoid moisture damage and weight loss.

Contamination is the primary risk to the can bale value. Food waste mixed with cans is charged a disposal fee rather than a revenue payment. Plastic or paper mixed with the can stream reduces the value below the aluminium rate. Cans that still contain liquid add unnecessary weight and can corrode the bale wire over time. Crushing cans before accumulation reduces storage volume and encourages liquid drainage, which improves cleanliness before baling.

“Recycling is one of the few commercial waste streams where the financial case is compelling even at small volumes,” says Conor Murphy, Director of Gradeall International. “A bar generating 500 aluminium cans per week is producing approximately £1,500 to £2,000 per year in bale value. That is real money from material that currently goes to general waste at a disposal cost. The investment case for even a compact baler is strong at this kind of value-per-tonne.”

Aluminium Cans in the Hospitality and Events Sector

The hospitality and events sector is the largest commercial source of aluminium UBC in the UK. A stadium seating 30,000 spectators at a sold-out event generates tens of thousands of aluminium cans. A busy city-centre bar generates hundreds per evening. Festival venues generate millions of cans per event at major outdoor events. The volume and concentration of cans wasted at these events make dedicated can baling equipment a straightforward investment for venue and event operators.

For hospitality and events operators seeking an integrated waste management approach covering cans alongside general waste and glass, Gradeall’s bottle crusher and large glass crusher complement the can baler as a complete front-of-house and back-of-house waste processing solution for high-volume beverage service operations.
