HFC (HFC)

HFC stands for hydrofluorocarbon, the third generation of fluorinated refrigerants that replaced ozone-depleting HCFCs in modern Indian air-conditioners and refrigerators. Because HFCs contain no chlorine, they have zero ozone-depletion potential and were initially considered the safe replacement. The two dominant Indian variants are R-410A (used in older split ACs from 2015-2020) and R-32 (the current default in new room ACs).

The climate problem: HFCs trade ozone safety for climate intensity. R-410A has a global-warming potential of 2,088 over 100 years; R-134a (used in domestic refrigerators) is 1,430; R-32 is the gentlest at 675. Venting a single 1.5-ton split AC charge of 1.2 kg R-410A is equivalent to releasing 2.5 tonnes of CO2 — comparable to a typical Indian household's annual electricity emissions. This is why the Kigali Amendment to the Montreal Protocol, which India ratified in 2021, mandates an 85% reduction in HFC consumption by 2047.

Recovery economics: HFCs command higher recycling-gate value than HCFCs because production is not yet restricted but virgin gas is expensive. Reclaimed R-410A sells at Rs 1,200-2,000 per kg in the Indian secondary market; R-32 at Rs 800-1,500 per kg. A well-equipped e-waste plant processing 50 ACs per day can generate Rs 60,000-1,00,000 monthly from refrigerant recovery alone.

Operational requirements: Recovery uses the same equipment as HCFC handling — sealed recovery machines, DOT-rated cylinders, vacuum capability. The E-Waste (Management) Rules, 2022 and the producer's EPR obligations both require refrigerant recovery documentation before any AC component enters the shredding line. Failure modes include cylinder overfilling (HFCs expand significantly with temperature, risk of rupture above 80% fill), cross-contamination between R-410A and R-32 cylinders (which destroys reclaim value), and refrigerant venting during outdoor unit transportation when service ports are damaged.
