A cold storage warehouse is a cold factory: refrigeration units, cold rooms, evaporators, condensers, copper pipework, stainless steel and steel panels. When the installation ages, when a warehouse is modernised or a cold room replaced, all this metal becomes scrap to recover — provided it is dismantled properly, starting with the depollution of refrigerants. In Morocco, the cold chain is growing fast: logistics warehouses, agri-food platforms, slaughterhouses, dairies, canneries and fishing ports all depend on industrial refrigeration, and their out-of-service equipment represents tonnes of copper, stainless steel and steel. This guide explains which metals a cold storage warehouse contains, how a refrigeration unit is dismantled, why depollution comes before any cutting, and how to organise collection without stopping operations.
The first point of method: a refrigeration installation is not a machine like any other. It contains pressurised refrigerants and oils, which must be recovered by a professional before any dismantling. Cutting a pipe still charged with refrigerant means releasing a harmful gas and risking cold burns — depollution is not an option, it is the first step of the job. Once the refrigerants are recovered and the circuits drained, dismantling becomes classic scrap work: sorting by metal, cutting, collection. Our article on dismantling industrial machines in Morocco describes this dismantling, and the one on the legal obligations for metal waste in Morocco the regulatory framework.
Which metals does a cold storage warehouse contain?
A cold storage warehouse concentrates three families of metals. Copper first: refrigeration pipework, evaporator and condenser coils, electrical cables, compressor and motor windings. Copper is the most present metal in a refrigeration installation, and also the easiest to sort — our article on copper purchase in Morocco details its recovery. Stainless steel next: interior linings of cold rooms, tanks, worktops and equipment in food preparation areas, in food-grade stainless steel. Steel finally: cold room structures, sandwich panels with insulating core, racks and shelving, insulated doors, frameworks and walkways.
Aluminium is present too: heat exchanger fins — those thin aluminium blades packed around the copper tubes — fan casings, door and window profiles. A condenser alone is an assembly of copper tubes and aluminium fins: the two metals must be separated before recovery, which sorting does after dismantling. The electric motors of compressors and fans add copper and steel: our article on recovering used electric motors covers these motors. In total, a complete refrigeration installation represents several tonnes of sorted metal.
The refrigeration unit: copper, aluminium and compressor
The refrigeration unit is the heart of the installation: compressor, condenser, evaporator, expansion valve, pipework and control cabinet. The compressor is a block of steel and cast iron, with an electric motor with copper windings — the heaviest and most metal-dense part of the unit. The condenser and evaporator are heat exchangers: copper tubes surrounded by aluminium fins, mounted in steel casings. The copper refrigeration pipes connect the different elements and are recovered in full lengths when accessible.
Dismantling a refrigeration unit follows a precise order: recovery of refrigerants and oils, removal of copper pipework, dismantling of heat exchangers, separation of aluminium fins from copper tubes, removal of the compressor and motors, then dismantling of the electrical cabinet and its cables. Each metal family goes to its own bin: copper, aluminium, steel, stainless steel. Units still in working order can also be resold second-hand before being recycled: reuse is always better than melting. For industrial air-conditioning equipment, read our article on recovering radiators and industrial air conditioning.
Cold rooms and sandwich panels: stainless steel and steel
A cold room is a metal room in its own right: sandwich panels in lacquered steel or stainless steel, insulated doors with aluminium frames, stainless steel rails and hooks, wall evaporators, chequer plate floors. When a cold room is dismantled, the panels come apart into flat elements, easy to stack and transport — clean scrap, without contamination, which sorts quickly. The stainless steel linings of food areas — slaughterhouses, dairies, canneries — are food-grade stainless steel: our article on stainless steel purchase in Morocco details its recovery, and those on slaughterhouse scrap and dairies cover these sites.
The equipment that accompanies the cold room adds metal: steel racks and shelving, forklifts and pallet trucks — our article on scrap metal from forklifts and handling equipment describes them — sectional doors, strip curtains, ventilation units. The insulating panels themselves need attention: their foam core is not metal and must be separated from the sheet before recovery. Clean dismantling separates the sheet from the insulation from the start, instead of leaving a mixture to sort on arrival.
Depollution first: refrigerants and oils
Before any cutting, a refrigeration installation must be depolluted: refrigerants are recovered into suitable cylinders by an equipped technician, compressor oils are drained and stored separately, filters and cartridges are removed. Refrigerants must never be released into the air: they are recovered to be regenerated or destroyed in approved streams. This is the rule that distinguishes professional dismantling from wild cutting, and it is also a regulatory requirement: hazardous waste — refrigerants, oils, batteries — follows streams separate from scrap.
Depollution also covers ancillary equipment: hydraulic oils from doors and cylinders, forklift batteries, condensates and defrost water. Scrap contaminated with oil or mixed with non-metallic waste must be re-sorted on arrival, which delays collection and degrades the lot. Sorting at source, in the warehouse that produces the scrap, matters as much as industrial sorting: our article on sorting metals in the company details this organisation. For used batteries, read our article on recycling used batteries in Morocco.
Dismantling a refrigeration installation without stopping operations
The challenge of a refrigeration dismantling is business continuity: a working warehouse cannot stop to dismantle a cold room. The job is therefore organised in phases: draining and isolating one line at a time, dismantling one cold room while the others keep running, transferring stocks to the remaining rooms, then dismantling the next line. Refrigeration units are replaced one by one, with progressive commissioning of the new equipment before removing the old.
This phased organisation requires close coordination between the operator, the refrigeration technician and the scrap collector: planning of interventions, temporary storage areas for sorted metals, regular collections to free space, agreed times so as not to disturb goods flows. For a complete warehouse clearance, read our article on factory clearance and recovery; for the collection process, the one on scrap metal purchase step by step. A well-planned job dismantles a complete installation without a single hour of warehouse downtime.
What happens to a cold storage warehouse's metal?
After dismantling and sorting, a cold storage warehouse's metal goes to the foundry: copper from pipework and windings becomes new ingots or cables, stainless steel from cold rooms becomes new sheets or equipment, steel from structures becomes profiles, aluminium from heat exchangers becomes alloy ingots. Recycled metal replaces virgin ore in production: that is the circular economy principle, and it makes refrigeration dismantling an industrial link in its own right. Our article on scrap metal from sorting centres and recycling facilities describes this passage through sorting.
For this chain to work, every link must be traceable: the warehouse selling its equipment must know where it goes, and the foundry buying it must know its composition. That is the collector's role: inventorying, sorting, weighing, documenting every lot and organising on-site collection, without interrupting the warehouse's activity. MOUMETAL operates throughout Morocco with this process: first contact by phone or WhatsApp, site visit to inventory the lots, depollution of refrigerants and oils before dismantling, sorting by metal with the warehouse teams, weighing and documenting the flows, collection by truck at agreed times.

FAQ — Scrap metal from cold storage warehouses and the cold chain
What should I do with an out-of-service refrigeration unit? Have it depolluted first — recovery of refrigerants and draining of oils by a professional — then dismantle it: copper pipework, copper and aluminium heat exchangers, steel and cast iron compressor, motors and cables. Units still in working order can be resold second-hand before being recycled.
Which metals does a cold room contain? Steel for sandwich panels, structure and doors, stainless steel for food linings and interior equipment, copper for pipework and evaporators, and aluminium for heat exchanger fins and door frames. The foam insulation is not metal and must be separated from the sheet.
How do I recycle a refrigeration installation? In three stages: depollution of refrigerants and oils, phased dismantling without stopping operations, then sorting by metal — copper, aluminium, stainless steel, steel — and collection to the sorting centre and then the foundry. Each lot is weighed and documented to ensure traceability.
Must the refrigerant be recovered before the scrap? Yes, always: the refrigerant is recovered into suitable cylinders by an equipped technician, before any pipe cutting. It must never be released into the air: it goes to an approved regeneration or destruction stream, separate from the scrap.
Who collects refrigeration equipment from a warehouse? Metal collectors and recyclers like MOUMETAL, which organise inventory, depollution, phased dismantling, on-site sorting, weighing and collection by truck, throughout Morocco, without interrupting the warehouse's activity.
