Disposing of old commercial refrigeration responsibly in India

What makes a refrigerator hazardous waste

• Refrigerant: older units may contain HCFC or HFC refrigerants with high global-warming potential; very old units may contain CFCs that damage the ozone layer. Newer units use hydrocarbons such as R290 or R600a, which are flammable.
• Insulation foam: polyurethane foam in older cabinets was often blown with ozone-depleting or high-GWP gases that remain trapped in the foam.
• Compressor oil, which contains dissolved refrigerant.
• Electronic controllers, wiring, lamps and, in some units, batteries.
• Metals worth recovering: steel, copper and aluminium.

The e-waste rules in brief

The E-Waste (Management) Rules, 2022 were notified by the Ministry of Environment, Forest and Climate Change on 2 November 2022, replaced the 2016 rules, and came into force on 1 April 2023. They are built around extended producer responsibility (EPR): producers of listed electrical and electronic equipment have recycling targets, and manufacturers, producers, refurbishers and recyclers must register on a portal run by the Central Pollution Control Board (CPCB). Refrigerators are among the equipment covered.

For a business disposing of equipment, the practical point is simple: hand e-waste only to a registered producer (through its take-back channel), a registered refurbisher or a registered recycler. Ask for proof of registration and a receipt. The rules and the list of covered equipment can change, so check the current position on the CPCB website or with your recycler before relying on details.

Your disposal options

• Supplier or manufacturer take-back: ask when buying a replacement whether the supplier collects the old unit and through which registered channel.
• Registered refurbisher: if the unit still works or can be repaired economically, refurbishment extends its life.
• Registered recycler: for units at the end of their life. Larger recyclers can collect from site.
• Avoid informal scrap dealers who cut lines to release refrigerant, burn cables to recover copper and dump foam.

Refrigerant must be recovered, not vented

Before a refrigeration unit is dismantled, its refrigerant should be recovered by a trained technician using a recovery machine and cylinder, so it can be recycled, reclaimed or destroyed. Venting refrigerant to the air releases greenhouse gases and, with older refrigerants, ozone-depleting substances. With hydrocarbon units, venting indoors also creates a fire risk. Ask the recycler or your service provider how refrigerant will be handled and who will do it.

Preparing a unit for collection

• 1. Empty the unit and dispose of food according to your waste procedures.
• 2. Switch off, unplug and defrost; mop up the water and empty the drip tray.
• 3. Clean the interior so it does not smell or attract pests while waiting.
• 4. Remove or secure doors and lids if the unit is stored anywhere accessible. A closed cabinet is a suffocation hazard for children.
• 5. Keep the unit upright and avoid damaging pipework, especially on hydrocarbon units.
• 6. Note the brand, model, serial number and refrigerant from the rating plate for the paperwork.

Keep the paperwork

Ask for a handover receipt or certificate from the registered entity that takes the unit, showing the item, quantity, date and their registration details. Larger businesses, hotel groups and chains with sustainability reporting will want these records; smaller businesses benefit from them too if questions are ever asked about where equipment went. Remove the unit from your asset list and your AMC so you are not paying for it.

Before you dispose: can it be reused?

A working unit replaced for capacity or format reasons may still have years of life. A refurbisher, a smaller business or a staff canteen may be able to use it. Make sure it is cleaned, checked by a technician and sold or donated through a channel that will dispose of it properly when it finally fails.

Safety notes

Isolate power before any preparation. Do not cut, drill or crush refrigerant lines. On units charged with R290 or R600a, keep flames and sparks away and store the unit in a ventilated place. Only trained technicians should recover refrigerant or open the sealed system.
