Aluminium is 100% recyclable with no loss of material quality - and unlike most construction waste that costs money to dispose of, aluminium offcuts have real monetary value. On facade projects, good waste management is not just an environmental consideration. It is a practical decision that recovers money and reduces site costs.
Why is aluminium scrap worth separating?
Aluminium can be recycled indefinitely without degradation. This is not a marketing claim - it is metallurgy. Recycled aluminium retains the same mechanical properties, corrosion resistance, and workability as primary aluminium. The alloy composition stays intact through the recycling process.
Recycling aluminium uses approximately 95% less energy than producing primary aluminium from bauxite. That energy saving makes recycled aluminium commercially valuable. The global recycling rate for aluminium sits at roughly 75%, and facade aluminium is particularly sought after by scrap dealers because it is a clean, known alloy - typically 6060 or 6063 series for extrusions, and 5005 series for sheet.
The practical takeaway: scrap dealers will actively collect your aluminium offcuts. A dedicated bin on site does not just keep the job tidy - it generates a return.
How should aluminium waste be managed on site?
Separation is the key. Aluminium mixed into general construction waste loses its value and ends up in landfill - where it could have been collected and paid for.
- Dedicated collection. Set up a separate skip or bin for aluminium offcuts. Keep it away from general waste and clearly labelled. The scrap value will more than cover the cost of the bin.
- Keep it clean and dry. Contaminated or mixed-material scrap attracts a lower price. Keep aluminium separate from steel, timber, and concrete waste.
- All offcuts count. interloQ extrusion offcuts and element13 panel offcuts are both valuable. Even small pieces have scrap value - do not throw them in the general skip.
- Remove non-aluminium items where practical. Screws, rivets, sealant, and brackets reduce the grade of your scrap. Cleaner scrap means a better price per kilogram.
How do you minimise waste in the first place?
The cheapest waste is the waste you never create. A few decisions early in the process make a significant difference:
- Module planning. Design panel sizes to minimise offcuts from standard element13 sheet sizes - 1250mm or 1500mm wide, in lengths of 3200mm or 4000mm. Consider the sheet dimensions before finalising panel modules.
- Nesting. For element13 panels, plan your cuts to nest efficiently on standard sheets. Good nesting can reduce material waste from 15-20% down to 5-10%. The savings on a large project are substantial.
- Accurate ordering. Order to measured quantities with an appropriate waste allowance - typically 5-10% for standard facades and 10-15% for complex geometry. Over-ordering means unnecessary offcuts and tied-up capital.
- Order to length. interloQ extrusions can be ordered to specific lengths up to 6-7 metres. Ordering to length eliminates cutting waste entirely for straight runs.
Valmond & Gibson can advise on sheet optimisation and panel sizing during the quoting process. Getting this right upfront avoids waste on site and improves your margin on the job.
Does aluminium recycling contribute to Green Star credits?
Yes. Demonstrating construction waste management - including aluminium separation and recycling - contributes to Green Star sustainability credits. Having a documented waste management plan that includes aluminium recovery strengthens a project’s sustainability credentials. For projects targeting Green Star ratings, aluminium’s inherent recyclability is a genuine advantage over materials that have no viable end-of-life recovery path.
What about aluminium waste on recladding projects?
Recladding projects present a specific waste consideration. The removed aluminium composite panels (ACPs) must be disposed of appropriately, as the polyethylene core cannot simply go into general waste. However, the aluminium skins of ACPs can sometimes be separated from the PE core for recycling - check with your waste contractor on whether they offer this service.
The replacement cladding - whether element13 solid aluminium panels or interloQ rainscreen - is fully recyclable at end of life. Solid aluminium panels are particularly straightforward to recycle because there is no composite core to separate. What goes up as a facade today can be melted down and reformed decades from now with no loss of quality.
Aluminium facade waste is one of the few construction waste streams that pays you back. Separate it on site, keep it clean, and plan your cuts well. The combination of scrap recovery and waste minimisation is good practice that benefits the project, the environment, and your bottom line.
