Garages, sheds and barns can produce a mix of materials. Keeping obvious metal, wood, electrical equipment and unknown materials apart helps a receiving facility classify them, but the final route depends on condition, contamination and what the authorised facility accepts.
The three main categories
- Scrap metal — ferrous (steel, iron) and non-ferrous (copper, brass, aluminium)
- Timber — keep clean wood apart from painted, treated or contaminated pieces
- Other material — classify it before collection rather than assuming it is general waste
Ferrous and non-ferrous metal
Metal is broadly split into two categories, which matters because they are recycled differently and can have different value:
| Type | Examples | Quick test |
|---|---|---|
| Ferrous | Steel, iron: tools, brackets, old machinery parts | A magnet will usually stick to it |
| Non-ferrous | Copper, brass, aluminium, lead | A magnet will not stick to it |
You do not need to grade metal precisely yourself. A magnet gives only a rough indication, so the collector or receiving facility must make the final classification. A business that buys, sells or stores scrap metal also needs the appropriate council-issued scrap metal dealer licence.
What counts as recyclable timber
Clean, untreated timber may have a recycling route where the receiving facility accepts it. Painted, varnished, pressure-treated or contaminated timber needs separate classification and may follow a different recovery or disposal route. Do not label all treated wood as general waste without checking the facility’s acceptance rules.
What usually ends up as general waste
- Mixed or contaminated materials that can’t be easily separated
- Broken plastic items and general household plastics
- Textiles and soft furnishings not suited to a specific recycling route
- Anything too degraded or damaged to identify clearly
A simple sorting guide
Rough sorting before a collection or clearance:
Frequently asked questions
Do I need to sort everything myself before a clearance?
No, a professional clearance separates materials as part of the job. Rough pre-sorting simply speeds things up and can help you understand what's involved.
Is treated decking recyclable as timber?
It normally follows a different route from clean untreated wood. Ask the collector or receiving facility how that treated timber is classified and accepted.
Does mixed scrap metal need to be separated by type?
You can group obvious metal together, but ask the collector how it will be graded and where it will go. Do not assume that recovered value will be credited unless the quotation says so.
What if an item is part metal, part wood?
Mixed items are usually separated where practical during processing, rather than needing to be split apart by hand beforehand.
Key takeaways
- Metal splits into ferrous (magnetic) and non-ferrous (non-magnetic) categories.
- Clean untreated timber and painted or treated timber may need different receiving routes.
- Rough pre-sorting helps, but the collector or facility must make the final classification.
- Flag anything you're unsure about rather than guessing which category it fits.
