Why Dispose of Paint Tins?
Aerosol cans are usually made of thin sheets of steel and alloy.

Moreover, the components in spray paints can are under high pressure that is why these used cans cannot be shifted to the garbage basket.
The chances of an explosion are there if these cans get exposed to heat. The extreme pressure in the garbage truck can also be the reason for the explosion.
The left-over paint in these aerosol cans is also extremely dangerous not only for your environment but for your health as it can cause the risk of diseases like cancer, among many others.
In some regions of the world, you can be fined for disposing of the used paint cans with the regular garbage.
Due to the presence of highly hazardous components in the paint cans, the local authorities are formulating strict laws for the safety of the general public and the environment.
Due to the above reasons, it is highly recommended to dispose of them properly in a safe place.

Depending on how much time and paint you have to dispose, you can use one of these methods.

Mix them lightly and add more after few minutes if required.
Once you find that the paint is solidified and is not spillable, you can close the paint can lid and dispose of safely.
2- Harden paint in cardboard box

- Line it with a large plastic trash bag
- Pour the paint slowly into the lined cardboard box to get a thin layer (less than one inch)
- Wait for a few hours and let the paint dry naturally
- Repeat the paint pouring process to get additional thin layers of paint until you have dried the entire paint
3- Paint newspapers or cardboard boxes
