3. Use as Animal Bedding
Avoid the cost of buying bedding for your small rodent friends by shredding your junk mail. It might also come in handy as bedding for your urban chickens.
4. Use as a Funnel
This works best with those return envelopes you get in the mail. Simply cut a small section of one corner of an envelope (for the bottom of the funnel) and a larger portion from its opposite corner (the mouth of the funnel). Use this to conveniently refill salt and pepper shakers. This idea is one of the useful ideas from JunkMailGems.com.
For these gardening projects, make sure there are no toxic adhesives or inks on the paper goods you use.
4. Make Seedling Pots
Another clever product is The PotMaker (about $15). You can use paper to make seedling pots, which can then be planted directly into the soil and will decompose on their own. This way, you don’t have to buy plastic pots (which saves money and resources).
5. Garden Mulch
You can literally lay out junk mail or old newspapers on your garden as a mulch. This makes an excellent weed barrier and will have all the benefits of traditional mulch. But since this is a little aesthetically displeasing, you might also want to cover with a layer of leaves or other traditional mulch.
Alternatively, you can also shred junk mail or old newspapers first and then lay them as mulch. This will break down easier.
