Watering Cans

Material A
Resin. Appears to be the most common material to manufacture watering cans out of, based on its water-resistance and durability.

Disposal: Resin must be placed in the garbage bin.

Material B
Plastic. Cheaper, affordable watering cans are often made of plastic which is treated to be water-resistant.

Disposal: Plastic of this kind, usually polyethylene, has to be placed in the garbage bin.

Material C
Steel. Although harder to find, steel watering cans still exist and can be purchased.

Disposal: Although hot dipped steel such as this can be recycled, it is recommended that you leave it curbside for collection, or take it to a drop-off depot so it can be recycled properly.

Best Alternative
The steel watering cans are the only ones that can be recycled. However, they bring the possibility of rusting, so then resin watering cans become the most realistic, as they provide a longer life. The best practice is to avoid cheap plastic watering cans as they are not often sturdy, and have to be placed in the garbage, ending up in a landfill.
