Making a compost bin is something which serves dual purposes, one, disposal of perished items and the second, making organic fertilizer free of cost. If there is a vegetable garden or the ornamental plants to be tended, there is nothing which works as magically as the organic fertilizer made of garden and kitchen waste. All it requires is a little bit of time and some sense of initiative. It is a good idea to make one yourself rather than purchasing from outside. A compost bin is a sure shot way of ensuring reproduction and growth of microorganisms.

The materials required to make a compost bin is a chicken wire measuring 4' in width and 12' in length and wooden stakes. Make a one and a half feet deep hole to place the wooden stakes such that the stakes are standing opposite each other. Start wrapping the wire around the two stakes so that it makes a circle. Use smaller wires to fix the chicken wire properly. You can also use nails or carpenter staples to fix the chicken wire to the stakes. Now you can put the compost pile inside. This makes the Circular wire compost bin.

Another compost bin is Two Section Cinder-block Compost Bin. To make this compost bin you will require 76 cinder-blocks measuring 8 inches by 12 inches. Cinder blocks should be taken depending on the size of the compost bin required by you. Now you need to make 3 1/2' x 6 1/2' rectangle. 3 blocks should be placed at the shorter end, leaving 3 inches between the blocks. Turn a block to the side and make the front in this manner. Now you can start placing the blocks in a line one after another. The end should be built with 3 blocks and the rear side with 5 blocks. After the first round is complete the next layer can be built in a similar manner to gain in height. The blocks can be placed alternately to make the use of blocks a little more economical. Mortar can be used to fix the blocks into concrete wall-like structure. The compost is done. Now you can divide the bin into two parts by using some more blocks and put the fresh compost on one side.

What happens in a compost bin is that microorganisms grow because of the nitrogen and carbon produced by the waste coming from plants and vegetables. The garden and kitchen waste from vegetables, flowers and fruits provide the much required nitrogen. Carbon is provided by the drier materials such as saw dust and dry leaves. Creating and using organic fertilizer generated from a compost bin is an ideal way of avoiding chemicals getting into the vegetables and fruits we eat.
