Step 1: Intro
I have a narrow galley kitchen where counter space is at a premium. I wanted a counter-top compost bin but couldn't find one small enough to justify the high price they carry.
I came up with the idea to use a simple metal mailbox - the kind that will hang on a wall, or sit on the counter taking up only a small amount of space.
One trip to the thrift store and I found what I was looking for! Clean and (apparently) unused at $3.99. Mine is 10-1/2"h x 8-1/2w x 3"d.
Step 2: Materials
- Wall-hung metal mailbox
- Mini kitchen bags designed for compost bins (compostable / biodegradeable) appx. size 17" x 16" (a bit smaller works fine)
- Two strong magnets (www.amazingmagnets.com is a great source)

Step 3: The Process
You can find mini kitchen bags at most hardware stores (I found them at Ace), and they fit perfectly in the mailbox.
Tuck the excess bag around to the back of the box and secure with a magnet on each side.

Step 4: It's that easy!
If you want, you can mount the mailbox inside your cabinet under the sink. Because the box is designed to be wall mounted, you will still be able to open the lid. The bag would need to be secured at the sides with the magnet if you do a wall-mount.
That's it!
