Aerosol Recycling

It's punctured and drained in a sealed system — such as the Aerosolv® Can Recycling System or NEWSTRIPE AeroVent® — which captures residual propellant and volatile organic compounds (VOCs) through carbon filtration before the empty can is baled for metal recycling.

A used aerosol can typically still holds pressurized propellant and residual product, which makes it a compressed gas container under most hazardous waste rules rather than plain scrap. Crushing or baling an unpunctured can risks a sudden gas release, fire, or explosion, so it has to be depressurized and drained in dedicated equipment before it can be handled like ordinary metal.

The steel or aluminum body is recovered as clean metal for remelting, while the plastic actuator and cap are typically separated out for plastics recycling. Any liquid or gaseous product residue drained from the can is captured separately and, depending on its chemistry, either fuel-blended, incinerated, or otherwise treated as regulated waste.

No — an aerosol can that is fully empty and non-pressurized can sometimes go directly into standard metal recycling, but any can with residual product or pressure needs to go through a puncture-and-drain unit first. Cans that contained highly flammable, corrosive, or otherwise hazardous formulations may require additional handling under hazardous waste regulations rather than the universal waste pathway used for most household and industrial aerosols.

In the United States, most spent aerosol cans fall under the EPA's Universal Waste Rule, which allows generators and handlers to manage them with lighter administrative burden than full RCRA hazardous waste while still requiring proper storage, labeling, and disposal timelines. Cans that don't qualify for universal waste status, or that are processed on-site by puncturing, may trigger additional RCRA hazardous waste generator obligations depending on the residual contents.

High-volume facilities use automated can-processing systems that puncture, drain, and shred large batches of cans continuously, feeding captured liquids into holding tanks and vapors through activated carbon filtration. Smaller generators, such as auto body shops or maintenance facilities, more commonly use benchtop or drum-mounted puncture units designed for lower daily volumes.

Recovered liquids are typically consolidated and sent for fuel blending, solvent recovery, or licensed hazardous waste disposal depending on their chemical makeup. Propellant gases, often hydrocarbons like propane or butane, are usually routed through carbon filtration or vapor recovery systems rather than vented directly to the atmosphere.

Draining and recycling aerosol cans keeps residual VOCs, propellants, and product chemicals out of landfills and open waste streams, reducing fire risk and soil or groundwater contamination. Recovering the steel or aluminum also feeds clean scrap back into metal markets, which is generally cheaper for generators than paying hazardous waste disposal rates for whole, unprocessed cans.

Yes, in most cases — puncture-and-drain systems are specifically designed to handle flammable propellants and hazardous residues by capturing them in a closed, ventilated environment rather than releasing them during handling. The captured hazardous liquid is then diverted to appropriate treatment or disposal rather than the metal recycling stream, so the hazard is managed rather than avoided.

Growth in personal care, food service, and industrial aerosol use is pushing more generators, from retailers to auto shops, to adopt on-site puncture units that let them reclassify spent cans as recyclable scrap rather than hazardous waste. There's also increasing attention to capturing and reusing recovered propellant and solvent streams rather than sending them straight to disposal, as facilities look to offset processing costs.
