Can You Compost Junk Mail?

Yes, the junk mails that overload your mailbox can be used as composting ingredients. The junk mails, however, should be vetted before they are placed in the compost pile.

For example, any junk mails that have plastic windows on the side of the envelope should be set aside and placed in the recycling bin. These days, some junk mails may also contain plastic cards inside to entice new customers.

Make sure those plastic cards don’t make it into your compost pile. Junk mail would be considered brown compost ingredients (source of carbon).
