From my college dorm room on, I've used plastic grocery bags for trash. I get them free, and, being small, they encourage frequent emptying of the trash, eliminating odors, fruit flies, and other assorted nastiness. Recently, I got to thinking about trashcans, another strange phenomenon. I had long used them, but for what? They are only another layer of container around the bag.
The UnTrashCan is a modern, stripped-down solution to all these waste problems. A simple frame holds a dozen bags; when one is filled up, it is pulled up and out, conveniently leaving a new, empty bag behind. The UnTrashCan serves as a storage solution for all those balled-up grocery bags, a striking piece of visual beauty for home and kitchen, and a neat resolution of all the thorny metaphysical problems posed by both garbage bags and garbage cans.
It took about two hours to make out of all-recycled wood, and is treated with a non-toxic, sustainable boiled linseed oil finish. All the pieces are small enough to be made out of scraps, and the design is easily modifiable to your particular materials. It could be built with just a drill and a circular saw in a pinch, but I used various shop tools for a better fit and finish.

You will need these materials:
Approx. 4' of 2" x 6" or similar
Approx. 18" of 2" x 8"
Approx. 2' of 1-1/2" square material
Approx. 8" of 3/4" dowel or similar
Approx. 6" of 3/8" dowel or similar
12 3" drywall screws
Finish of your choice
You will need these tools:
Step 1: Feet and Legs
Next, cut the feet into two 12" sections. Cut two sections of 2" x 6" to 24". Turn the chop saw to 10o, and cut two opposing miters into the 2" x 8". The shorter side of the piece should be about 14-1/4", which will determine how far apart the legs sit and the tension of the stretched bag.
It should be noted that the legs in mine are not a true 2" x 6"s; they are some old shop scrap that are a little less than 5" wide. They fit the shopping bag handles pretty well, though a little loose. You might want to rip down the 2" x 6" some, or just carve away a little at the top ends witha jigsaw.
