How to Safely Dispose of Household Paint Over time,

the houses we live in naturally develop areas that become damaged or where the paint fades due to age. This means repairs or renovations are often necessary, and repainting is an almost essential step to restore a house to its original beauty. However, it’s common to have leftover paint remaining in cans or buckets once the job is finished. If this leftover paint is not disposed of properly, it can pose risks to both the environment and human health. Therefore, for safety and sustainability, it’s important to handle and dispose of paint correctly and responsibly.

What can you do with leftover paint?

• Assess the paint’s condition: If the paint is still usable, keep the lid tightly closed and store it in a dry place for future use. You can also donate it to organizations in need, such as schools, temples, or volunteer groups that help renovate community spaces.
• If there is only a small amount left at the bottom of the can that is not enough for a new paint job, you should handle it separately as follows:

Water-based paint : Open the lid and leave the can open to let the paint dry completely, or pour the paint onto an absorbent material such as sand or newspaper. Once the paint has dried, it can be disposed of with regular household waste. The empty container can be recycled according to the instructions on the packaging.

Oil-based paint : Take it to a hazardous waste collection point, as this type of paint contains chemicals that may be toxic.

Besides leftover paint, what else should be handled properly?

• Thinner: Never pour thinner directly into drains or onto the ground, as it can contaminate water sources and soil. Used thinner should be taken to a hazardous waste collection point or a chemical waste disposal center.
• Painting tools: Painting tools that are completely dry, such as paint brushes, rollers, or paint trays, can be disposed of with regular household waste. However, if they are still wet, place them in a separate bag and dispose of them as hazardous waste. If you plan to reuse them, remove as much paint as possible and clean or soak them with a suitable solvent according to the type of paint. Store brushes or rollers in a sealed plastic bag to keep them ready for future use.
