Reduce
Only buy the amount you require for the job (the guidelines on the tin will help you assess this) and use it all up, to avoid leftover paint.
Reuse
Keep any leftover paint for future use, such as recoating or patching.
Read some great tips for keeping paint so it can be used again.
You can also offer any leftover paint to friends, neighbours, relatives if you have no use for it and are unable to store it for future use.
Disposal
Small amounts (such as less than a quarter tin-full) of emulsion or acrylic paint can, once dry and solid, can be double-bagged and disposed in the household rubbish bin, or the non-recyclable container at any Suffolk Recycling Centre.
To aid the drying process: the lid should be left off, and sand, dirt, sawdust or clean cat litter can be added but please ensure the paint has completely solidified before placing in the bin or taking to the Recycling Centre (you may need to leave it for a couple of weeks before disposal).
Solvent-based paints or large quantities of paint cannot be treated in this way and can only be disposed of through the hazardous waste collection service.
