Clothespins

Material A
Hardwood. The two moving pieces are usually held together with a steel wiring.

Disposal: Clothespins can be placed in your garbage bin.

Material B
Plastic. Just like wooden ones, these clothespins are also held together with a steel wiring.

Disposal: Clothespins can be placed in your garbage bin.

Best Alternative
Based on the large quantities and inability to recycle them, it is recommended to donate any old clothespins that you are not using to any not-for-profit organizations that can ensure reuse. Alternatively, investing in heavy duty metal clothespins, albeit more costly, can replace countless clothespins that would have ended up in the garbage bin and eventually in a landfill.
