Paint & Chemical Disposal in Australia

Leftover paint and household chemicals are among the most commonly mishandled items in Australian homes. Pouring them down the sink, tipping them onto the ground, or sneaking them into the kerbside bin all cause real harm — these products contain solvents, heavy metals, and other compounds that contaminate soil, waterways, and the recycling stream. The good news is that Australia has well-established, free programs for disposing of paint and chemicals responsibly, so there's rarely a reason to get it wrong.

The Paintback scheme

Paintback is Australia's dedicated product stewardship scheme for paint and paint packaging. Funded by a small levy added to the price of paint at the point of sale, it lets households and trade painters drop off unwanted paint for free. Since launching in 2016, Paintback has diverted many thousands of tonnes of paint from landfill and waterways.

Paintback accepts:

• Water-based (acrylic) and solvent-based (enamel) paints
• Paint tins and containers (empty or with leftover product)
• Varnishes, stains, and some sealants
• Up to 100 litres per visit at most sites

There are collection points across every state and territory — many at council waste transfer stations and resource recovery centres. Use the site locator at paintback.com.au to find your nearest drop-off. Note that Paintback does not accept aerosol spray paints, industrial coatings, or paint from containers larger than 20 litres.

Household chemical collection events

For chemicals other than paint, most states run free household chemical collection programs. These are the correct destination for garden and pool chemicals, solvents, cleaning products, fuels, and similar hazardous items.

• NSW — the EPA runs regular free Household Chemical CleanOut events; dates and locations are published on the NSW EPA website.
• Victoria — Sustainability Victoria's Detox Your Home program offers permanent drop-off sites and mobile collection days.
• Queensland — many councils host free hazardous waste days, and some transfer stations accept chemicals year-round.
• SA, WA, ACT, TAS, NT — councils and state agencies run drop-off points and periodic collection events; check your local council website.

What never goes in your bins

Some items must never go into any kerbside bin — general waste, recycling, or green — because they are hazardous, flammable, or damaging to sorting equipment and staff:

• Liquid paint (wet paint contaminates recycling and leaks in trucks)
• Solvents, turpentine, mineral spirits, and thinners
• Garden chemicals, weed killers, and pesticides
• Pool chemicals such as chlorine
• Motor oil, brake fluid, and petrol
• Gas bottles and aerosol cans that still contain product

Can dried paint go in the bin?

Some councils allow fully hardened water-based paint residue in general waste, while others direct all paint to a hazardous-waste or Paintback service. Check your council's guidance first. Paintback accepts eligible water-based and solvent-based architectural paint, so using its locator avoids relying on a general rule about dried paint.

Aerosols and spray paint

Aerosol cans are pressurised and can explode if crushed or heated, so they're a fire risk in bins and trucks. Completely empty aerosols can often go in kerbside recycling in some council areas, but partially full cans should go to a household chemical collection. Never pierce a can to empty it. Spray paint cans in particular usually need to go to a chemical drop-off rather than the recycling bin.

Common mistakes

• Pouring paint down the drain or gutter. This sends contaminants straight into stormwater and waterways — and it's illegal in most areas.
• Tipping leftover chemicals onto the garden. Solvents and pesticides poison soil and can reach groundwater.
• Putting wet paint tins in the recycling bin. Liquid paint contaminates an entire load of otherwise recyclable material.
• Assuming all paint is the same. Enamel and acrylic paints need different handling; when unsure, take both to Paintback.
• Hoarding old chemicals in the shed. Ageing containers corrode and leak — dispose of them at a collection event rather than letting them degrade.

Frequently asked questions

Is Paintback really free?

Yes. The cost is built into the price you pay when buying paint through a levy, so dropping off unwanted paint at a Paintback site costs you nothing at the counter. Both DIY households and professional painters can use it.

Can I take a full, unopened tin of paint to Paintback?

Yes — Paintback accepts paint whether the tin is full, part-used, or empty. If the paint is still usable, consider donating it to a community group, men's shed, or theatre company first, as reuse is even better than recycling.

What do I do with old pool or garden chemicals?

Take them to a household chemical collection event or a permanent hazardous waste drop-off run by your state agency or council. Keep them in their original labelled containers, and never mix different chemicals together.

Can I put an empty paint tin in recycling?

Metal paint tins that are completely empty and dry can go in kerbside recycling in many council areas, but rules differ. If any wet paint remains, take the tin to Paintback instead.

How should I store chemicals before disposal?

Keep them upright, sealed, and in their original containers with labels intact, out of reach of children and pets, and away from heat or ignition sources. Don't decant chemicals into unlabelled bottles.
