R404A (HFC blend) disposal: complete guide

Reviewed by the eCycling Central editorial team on April 2026

R404A (HFC blend) has a Global Warming Potential (GWP) of 3922, ozone depletion potential of none, and is classified as A1 non-flammable. It is typically used in commercial refrigeration, supermarket display cases.

Why R404A (HFC blend) disposal is regulated

A refrigerant's GWP is the single most important factor in how strictly its disposal is regulated. R404A (HFC blend) releases the same warming impact per kilogram as 3922 kg of CO2 when vented to atmosphere.

The phase-down regulatory status: EU bans new equipment with charge >40 tonnes CO2e from 2020.

Where R404A (HFC blend) is found

R404A (HFC blend) is the standard refrigerant for commercial refrigeration, supermarket display cases. If you have an appliance manufactured during this period and the data plate shows R404A, this guide applies.

How to legally dispose of equipment containing R404A (HFC blend)

The refrigerant must be recovered (captured into a sealed cylinder) before the equipment is broken down. This requires a person holding an F-Gas Category I certificate (EU, UK), Section 608 certification (US EPA), or country-equivalent.

The route for typical owners:

Do not attempt to remove or vent the refrigerant yourself - this is illegal and dangerous (the A1 non-flammable classification means the gas may be flammable or asphyxiating)
Use one of: manufacturer take-back programme, retailer take-back when buying replacement, local-authority bulky-waste collection, or commercial F-Gas certified disposal contractor
Keep the receipt or recovery certificate if available - useful for end-of-life evidence in commercial contexts

Penalty for venting R404A (HFC blend)

EU: up to €100,000 per violation under F-Gas Regulation 517/2014, plus member-state criminal penalties
UK: up to £200,000 fine (Environmental Protection Act) plus prosecution by the Environment Agency
US: up to $25,000 per day per violation under EPA Section 608

Frequently Asked Questions

Is R404A (HFC blend) banned?

EU bans new equipment with charge >40 tonnes CO2e from 2020. Service of existing equipment may continue under conditions, but new equipment containing R404A (HFC blend) faces tightening restrictions in the EU and US.

What is the GWP of R404A (HFC blend)?

3922 (per IPCC AR6). This means 1 kg vented has the same warming effect as 3922 kg of CO2 over a 100-year period.

Can I vent a small amount of R404A (HFC blend) myself?

No. Venting any quantity of R404A (HFC blend) to atmosphere is a regulatory offence in the EU, UK, US, and most developed-economy jurisdictions. R404A (HFC blend) must be recovered by a certified handler.
