Scrap metal recycling turns discarded metal into reusable raw material, cutting waste, conserving natural resources, and returning value to whoever recycles. So what is scrap metal? It is any metal left over from manufacturing, construction, end-of-life vehicles, or household and industrial items that can be recovered and melted into new products. This guide explains how the recycling process works, which materials carry the most value, and how scrap motors such as alternators and starters are processed.
Overview: Scrap metal recycling recovers metal from end-of-life vehicles, buildings, appliances, and industrial waste, then sorts, processes, and re-melts it into new raw material. Non-ferrous metals like copper, brass, and aluminium hold the most value, and items such as alternators and starter motors are a dependable source of recoverable copper.
Recycling metals plays a crucial role in environmental conservation by reducing the need for virgin ore mining, which in turn lowers greenhouse gas emissions and saves energy. Recycled metal can be reused almost indefinitely without losing its properties, which makes scrap metal recycling both an efficient and a sustainable practice. Every tonne kept in circulation is a tonne that does not need to be dug out of the ground.
The scrap metal recycling process involves several key steps that take material from the yard to a refiner ready to re-melt it.
Before anything is weighed, scrap is split into two families, and knowing which is which helps you anticipate value. Ferrous metals contain iron, are magnetic, and tend to rust; common examples include steel and cast iron from car bodies, appliances, and structural offcuts. They are widely recycled but usually carry a lower price per tonne. Non-ferrous metals contain no iron, resist corrosion, and hold their value far better; copper, aluminium, brass, lead, and zinc all fall into this group. A simple magnet is the quickest first test: if it sticks, the item is ferrous; if it does not, you are likely holding the more valuable non-ferrous material. Most of the recoverable value in mixed loads, including the copper inside motors and cables, sits firmly on the non-ferrous side.
Almost any metal can be scrapped and recycled, and knowing what metals can be scrapped, along with where they usually come from, makes it easier to spot value around a home, garage, or worksite. The table below covers the most common scrap metals and their everyday sources.
| Metal | Type | Common sources |
|---|---|---|
| Steel | Ferrous | Construction materials, vehicle bodies, household appliances |
| Cast iron | Ferrous | Engine blocks, pipes, radiators, machinery |
| Wrought iron | Ferrous | Fencing, railings, garden furniture |
| Copper | Non-ferrous | Electrical wiring, plumbing pipes, electronics, motors |
| Brass | Non-ferrous | Plumbing fixtures and fittings, instruments, decorative items |
| Lead | Non-ferrous | Batteries, roofing, pipes, cable sheathing |
| Alloy wheels (aluminium or magnesium) | Non-ferrous | Cars and motorcycles |
| Scrap motors | Non-ferrous (copper-rich) | Starters, alternators, AC pumps, electric motors |
Blancomet specialises in the non-ferrous metals in this list. Ferrous metals such as steel and cast iron are widely recycled elsewhere, but the highest recoverable value usually sits with copper, brass, and copper-rich components.
At Blancomet, we focus on recycling a range of non-ferrous metals and components, each with its own opportunities and challenges.
Copper is highly prized for its conductivity and durability. We recycle all forms of copper cable, from car wiring looms to household cables, so this valuable resource is reused rather than lost.
We accept various forms of copper, including bright copper, burnt copper, and oxy copper. Each grade goes through a meticulous process to prepare it for new uses.
Known for its resilience and appearance, brass is widely used in fixtures, fittings, and decorative items, which makes brass recycling a significant part of our operations.
Alloy wheels, usually aluminium or magnesium alloys, are lightweight and strong. Recycling them reduces demand for new metal production.
Despite its toxicity, lead is recyclable and widely used in batteries and industrial applications. Proper handling ensures it is processed and reused safely.
Scrap alternators and starter motors can look like low-value, awkward lumps of metal, but handled correctly they become a reliable revenue stream. They contain valuable copper, aluminium, and steel, and a clear workflow turns them into a steady side stream for salvage yards and garages.
In a vehicle context, scrap motors usually means small electric motors and related units from end-of-life cars, vans, and light commercial vehicles: alternators, starter motors, small accessory motors (window, wiper, blower), electric power steering motors, and hybrid or EV ancillary motors such as coolant and vacuum pumps. They arrive from vehicle dismantlers, independent garages, fleet workshops, and bodyshops. Many alternators and starters still have a second life as remanufactured units; once they are clearly beyond repair, they move into the scrap stream.
From a yard’s perspective the first step is simple removal and storage, with detailed dismantling happening at a specialist facility. A typical line runs through four stages, mirroring what peer-reviewed research on recycling electric motors from end-of-life vehicles describes:
At the end of the chain the processor has relatively pure streams of copper, aluminium, and steel ready for refiners and foundries. Modern facilities use dedicated shears, granulators, and hammer mills to do this at scale, though research on circular copper recovery from electric motors notes that mixed-metal shredding can reduce the quality of the recovered copper.
The value of a load comes down to a few factors. Copper content is the biggest one, since copper is the highest-value metal in traditional alternators and starters, so copper-rich units grade higher than light accessory motors with more aluminium and plastic. For a closer look at how copper grades and prices are set, see our 2026 UK scrap copper cable guide. The mix of motor types matters too, with large truck and bus units, standard passenger units, small accessory motors, and EV or hybrid motors often graded separately. Contamination is the third factor: loads free of loose wiring, brackets, and excess oil, and packed consistently, grade better because they are lower risk and less labour intensive. Finally, underlying market prices for recovered copper, aluminium, and steel set the baseline.
| Component | Main material | Recovery route | Notes for yards and garages |
|---|---|---|---|
| Windings | Copper (sometimes aluminium) | Sold to refiners for re-melting | A higher copper proportion improves grading for the load. |
| Housings | Steel or aluminium | Steel works or aluminium smelters | Heavy housings add weight; keep them attached unless the buyer asks otherwise. |
| Shafts, laminations | Ferrous steel | Recycled through ferrous streams | Processed as part of the motor; no need to separate on-site. |
| Plastics and rubber | Mixed polymers | Energy recovery or specialist recycling | Remove obvious loose plastic where practical to cut contamination. |
| Electronics (some alternators) | PCBs, semiconductors | Separate e-waste or precious metal recovery | Can intersect with e-waste streams, especially on newer vehicles. |
Compared with batteries or fluids, alternators and starters are relatively low risk, but responsible handling still matters. Starter motors hold grease in their gears and bushings, and alternators carry traces of oil and road grime, so excess should be managed through normal workshop waste procedures to avoid contaminating stored motors. Insulation varnish and plastics are burned off or separated during industrial processing, so removing every trace on-site is unnecessary; the goal is simply to avoid heavy contamination with unrelated materials. Newer smart alternators and starter-generator systems carry built-in electronics that can fall under e-waste rules when stripped separately.
A little preparation at your end improves grading and speeds up settlement. The basics are simple: sort alternators and starters into clearly labelled stillages or cages by type rather than mixing them with general scrap; drain any excess oil and remove obviously loose plastic, brackets, and wiring looms that are not part of the motor; and keep the load under cover, away from spilled fluids and dirt that count as contamination. If you handle larger commercial-vehicle units or EV and hybrid motors, batch those separately, since they often qualify for a different grade. When a cage is full, arrange collection alongside your other non-ferrous loads so everything moves on one consolidated trip, and match collection notes to your own records to reconcile weights and grades later.
They should stop treating metal as general rubbish and start separating it at source. In 2026, metal in the black bag is both a compliance risk and a missed income line, because UK workplace recycling rules now expect businesses to keep recyclable streams, including metal, out of residual waste.
In England, the Simpler Recycling rollout makes separate collection of core recyclables a workplace duty, with firms of 10 or more full-time-equivalent staff already in scope and micro-businesses required to comply by 31 March 2027. According to GOV.UK, workplaces in England need arrangements for streams such as metal rather than treating everything as residual waste. Wales has its own duties, and small waste electrical and electronic equipment comes into scope from 2026; see GOV.WALES. Scotland has had workplace recycling rules for years, and Northern Ireland sites should check local arrangements rather than copying an England-only setup.
The items most often missed are exactly the ones with recoverable value: cable tails, brass fittings, aluminium trays, old chargers, routers, and broken kettles. These are non-ferrous metals hiding in everyday waste. They look like clutter, not metal, so they drift into general bags where they earn nothing and add disposal cost.
| Business type | Typical items missed | Better route |
|---|---|---|
| Office | Chargers, cable, desk lamps, IT accessories | A separate box for small electricals and clean metal parts |
| Electrical and plumbing trades | Copper cable, pipe offcuts, brass fittings, taps | Dedicated containers in vans and at the yard |
| Hospitality | Aluminium trays, foil, cans, worn pans, fixtures | Clearly marked kitchen and storeroom bins |
| Light manufacturing | Offcuts, rejects, stamped parts, cable, housings | Stream-by-stream segregation near the process line |
A simple setup fixes most of it: identify the metal streams you create every week, place clearly labelled containers where the waste actually appears, and arrange regular drop-off or collection with a licensed recycler. Use plain labels like “Cable only” or “Small electricals” and keep one short contamination rule such as no food, no plaster, no general rubbish.
Once metal becomes a repeat stream rather than a one-off clear-out, a specialist recycler usually handles it better than a general mixed-waste contractor: the material stays cleaner, collection fits the waste type, and records are clearer for duty-of-care and ESG reporting. If you are comparing suppliers, searching for scrap metal collection near me is only step one; ask which metals are taken separately, whether small electricals are handled, and what paperwork you receive after each load.
Blancomet offers competitive rates for non-ferrous metals and their components, with consolidated collections that let alternators and starters travel alongside your wider non-ferrous loads such as alloy wheels, copper cables, and radiators. Whether you are looking for a scrap yard metal near me or simply want predictable grading and clear settlement, our facilities across the UK and Ireland make dropping off or arranging collection straightforward.

Scrap metal is any metal left over or discarded from manufacturing, construction, end-of-life vehicles, appliances, and other items that can be recovered and recycled. It is grouped into ferrous metals, which contain iron and are magnetic, and non-ferrous metals such as copper, aluminium, brass, and lead, which resist rust and tend to hold more value.
In most cases, sending alternators and starters whole is the most practical approach. Industrial processors have the equipment to separate copper, aluminium, and steel at scale, and hand-stripping on-site often costs more in labour than it returns. The main job for yards and garages is sorting by type and keeping loads reasonably clean.
No. Processors expect a normal amount of plastic housings, fans, and connectors. Removing obvious loose plastic, rubber, and unrelated waste helps your grading, but you do not need to break every unit down. Focus on preventing excessive contamination rather than making the motors look perfect.
Motors are usually collected in stillages or cages and weighed on a calibrated scale, either at your site or at the processor’s facility. The load is then assigned to an agreed grade based on type, mix, and cleanliness. Agreeing those grades upfront and keeping on-site sorting consistent helps settlement match expectations.
Ancillary EV and hybrid motors, such as coolant or vacuum pumps, follow similar routes to traditional alternators and starters, though some designs use different materials and more electronics. Main traction motors and high-voltage components are a separate category that follows specialist EV dismantling routes with extra safety steps.
Most yards find it efficient to separate alternators and starters alongside other non-ferrous items like alloy wheels, copper wire, and radiators. Where you also remove catalytic converters, batteries, or electronic modules, it is worth arranging coordinated collections so each stream reaches the right specialist facility while keeping storage and admin simple.
No. A Scrap Metal Dealer’s Licence is only required if you buy or sell scrap as a commercial activity, such as a yard or mobile collector. An SME selling off its own offcuts, fittings, cable, or end-of-life equipment to a licensed buyer does not need a personal licence. You should, however, make sure the recycler you use is licensed by their local authority under the Scrap Metal Dealers Act 2013.
No. Cash payments for scrap metal have been illegal in the UK since 2013. A licensed dealer must pay by bank transfer, cheque, or another traceable method. If a buyer offers cash, that is a clear sign they operate outside the law, and selling to them puts your business at risk under duty-of-care rules.
Copper remains the highest-value common scrap metal, especially clean bright wire and tube grades, followed by brass and aluminium. Grade and cleanliness have a major effect on price, so even basic separation, such as keeping copper away from brass and removing insulation where practical, directly increases what your business earns.
Yes, though the timetable is more generous. In England, businesses with 10 or more full-time-equivalent staff are already in scope of Simpler Recycling, while micro-businesses must comply by 31 March 2027. Wales, Scotland, and Northern Ireland run on different schedules, but the underlying expectation to separate recyclable materials including metal applies across all four nations.
From April 2026, businesses that produce, handle, or dispose of waste in the UK must log waste movements on a centralised digital platform. For most SMEs the practical impact is minimal if you use a licensed recycler, since the operator handles the bulk of the reporting, but you may be asked for slightly more detail at weigh-in, so keep your own copies of waste paperwork to match the digital record.
