You have three main options for what to do with empty paint cans: dispose of them safely, recycle them, or upcycle them into something useful or decorative.

1. Basic safety rules

  • Never pour leftover paint down drains, outside, or into soil; it can harm water systems and wildlife.
  • Check the label: latex/water‑based paint is usually less hazardous than oil‑based, which is often treated as hazardous waste.
  • Always follow your local council or waste service rules, because what’s allowed in regular trash varies by region.

2. If the can still has paint

Even if your main question is “what to do with empty paint cans,” a lot of “empty” tins still have some paint sloshing at the bottom.

Try to reuse or donate

  • Ask friends, neighbours, or local community groups if they can use it for touch‑ups, small rooms, or craft projects.
  • Donate good‑condition paint to charities, community centres, theatre groups, art studios, or building‑reuse programmes where available.
  • Offer it on local “buy nothing” or freecycle‑type groups; leftover paint is often snapped up for furniture flips and rentals.

Dry it out, then bin or recycle

For small amounts of leftover latex/water‑based paint:

  1. Brush remaining paint onto scrap cardboard or paper and let it fully dry; then put the dry paper in the household bin.
  1. For a few centimetres of paint in the bottom, mix in sand, soil, sawdust, or commercial paint hardener until it forms a thick sludge.
  1. Leave it to dry completely (often overnight or longer, depending on depth).
  1. Once rock‑hard, most areas allow you to dispose of the can with normal rubbish or at a recycling centre (check local rules).

For oil‑based or solvent paints:

  • Treat them as hazardous; take the can (even if it’s “nearly empty”) to a household hazardous‑waste facility or special collection event rather than drying and binning.

3. When the can is truly empty

“Empty” here means no liquid paint moves when you tilt it and the inside is scraped as clean as it reasonably gets.

Metal paint cans

  • Many recycling centres accept empty metal paint cans for metal recycling.
  • Often you must ensure any paint is completely dry or just a thin residue before they’ll take it.
  • If your area doesn’t take them at kerbside, drop them at a household waste recycling centre and follow onsite signs for metals.

Plastic paint cans

  • Plastic paint pots are less widely recyclable, but many local centres will at least accept them for correct disposal.
  • Some regions are piloting specific schemes to recycle plastic paint cans separately; local councils or DIY retailers may list participating sites.

4. Upcycling ideas (turn cans into decor)

If you like DIY or want to reduce waste, empty paint cans are ideal upcycling material once they’re fully clean and dry.

A few popular projects:

  • Planters and flowerpots:
    Clean thoroughly, drill drainage holes, then paint and seal the outside; good for ornamental plants (avoid edibles because of metal/paint contact).
  • Storage containers:
    Use them (lid on or off) to store brushes, tools, craft supplies, kids’ art materials, or even kitchen utensils after decorating the outside.
  • Decorative buckets:
    Create ice buckets, party favour “buckets,” Halloween trick‑or‑treat pails, or picnic caddies by painting patterns or motifs on the cans.
  • Desk and workshop organisers:
    Mount several cans on a board or wall to hold screws, nails, pens, and other small items; label or colour‑code for quick finding.

Creators online show techniques like checkerboard patterns and stencilled flowers using primer, masking tape, and sponges to transform old tins into stylish containers.
