How To Build an Eco Friendly Composting Toilet How To Build an Eco Friendly Composting Toilet
Anyone can learn how to build an eco-friendly composting toilet. You can easily make compost for gardening out of human waste that will feed the soil and produce healthy plants.
Step 1: Build the Framework for the Toilet Seat and Lid
Cut a hole the size of a 5-gallon bucket in the larger piece of plywood and position the board so that the hole is 1 1/2 inches from the front. Place the 2 pieces of plywood side by side and hinge them together. The larger piece will serve as the entrance for the bucket.
Step 2: Assemble the Base
Screw the four boards together to build a box that is 10 inches deep, 18 inches wide and 21 inches long. Screw the 3x18-inch plywood board to the box, leaving the larger plywood free to lift.
Step 3: Adjust the Height and Attach the Legs
Adjust the height of the four legs so that the bucket protrudes about a half an inch through the plywood top, and screw the legs to the inside of the box.
Step 4: Make Adjustments to the Toilet Seat
Turn the plastic bumpers on the standard toilet seat so that they are set sideways and will allow the bucket to rest against the bottom of the toilet seat ring.
Step 5: Attach the Toilet Seat
Place the toilet seat over the hole in the plywood and mark holes where the seat should attach. Drill holes and attach the seat to the box.
Step 6: Finish Your Toilet
Stain and varnish the composting toilet, place the bucket into the box and it is ready to be used.
Step 7: Use and Maintain the Toilet
Cover the bottom of the empty bucket with about 2 inches of sawdust and place it in the toilet stand and use. After use, sprinkle some sawdust on top of the waste and cover with a lid. When the bucket is full, remove it, cover and replace it with an empty bucket. Empty out the full bucket into the center of your compost heap and cover the new compost with old compost or leaves.
If you do not have sawdust, you can use peat moss or coconut coir to create air pockets that will aid aeration and balance the nitrogen level. Human waste is high in nitrogen and the sawdust balances it with its high carbon level, which is better for the soil. Now you are ready to go.
