How to Build a Compost 3 Level Bin


The science of composting has been well established since Sir Albert Howard introduced the Indore method of composting in the 1940s. According to modern composting theory, you can reduce organic waste to compost in as quickly as 6 weeks by building a compost pile that is at least 3 feet square and stirring the contents every few days. But if you live in a small space, this can be a difficult prospect. The answer is a three-level stacking compost bin.

Step 1

Lay 4 30-inch-long boards onto a flat surface to form a square with abutting corners.

Step 2

Secure these corners by placing an L-bracket over each one and drilling a wood screw through the outer L-bracket hole.

Step 3

Repeat this process to create a second box.

Step 4

Place a 16-inch board on its end so that two sides of the board are flush with the corner of a box.

Step 5

Secure the board to the corner of the box by drilling a screw through each of the inner holes of the L-bracket.

Step 6

Repeat this step three more times with the three remaining corners of the box. The resulting structure should look like an upside-down table.

Step 7

Turn the structure over and place it inside the other square so that the 16 inch boards stand in the corners of the wooden square. Secure the square to the boards following the process outlined in step 5. The result should be the wooden skeleton of a box.

Step 8

Cut four wire squares that are 30 inches long and 16 inches wide from the wire screen. Cut a fifth square that is 30 inches on each side.

Step 9

Attach the 30-by-16-inch screen squares to the sides of the box using fencing staples and a hammer. Attach the 30-by-30-inch screen square to the bottom of the box. You've now made your first bin.

Step 10

Repeat steps 1 through 9 twice more to create the remaining two bins. Stack the three bins on top of one another.
