This spring and in with keep with green and sustainable ethics we are going attempt to turn a kampa khazi into a composting toilet saving on the water used and making our own compost. Before we start I hasten to add as its basically a fancy bucket it’ll be used for number ones only and not number twos. Even though its perfectly ok to use this method for both. By using compost as a base and a old water but as the composter hopefully we can make good compost in quick time.
For a couple of years now, we have been thinking about using a composting toilet mainly to save the club money on the water bill. Also its fun trying to think of ways to recycle and also help save the environment. I must have saved a fortune not having to wash my clothes as much,but there is still alot more that can be done. Here is a sanitary way to turn “waste” into fertilizer. It starts with the collection device, and ends with the composting device designed to make fertilized dirt. There is no “waste”.
What makes this sanitary and earthy smelling instead of just a bucket of waste is the cover material.
Step 1: Covering Material
Cover material can be grass clippings, Peat Moss, Coconut Coir (recycled coconut fibers), ground up corn cob, or even sawdust (raw wood preferred, not kiln dried). Our favorite is the Recycled Coconut Coir (a waste product from the food industry) and the ground corn cob.
Put about 3″ in the bottom of the bucket before use to act as a liquid absorbent and after every deposit, cover with another inch or so.
Some folks use a plastic bag liner, especially when camping. This makes it easier to keep the bucket clean, but harder to compost, as the bag needs to be disposed of. Biodegradable bags exist, but still problematic for composting. Perfect for camping in the woods.
Step 2: Composting
When the bucket is about 3/4 full, take it outdoors and dump it into your compost bin. Again, you can cover with dry materials, this time lawn / garden cuttings, to eliminate smells and flies. You can build your own compost bin with a 55 gallon drum (with aeration holes), a stack of tires with the sidewalls cut out, pallets, or purchase one already made.
Step 3 Using the Compost
After a year of composting, the resulting compost is perfectly safe to use in the vegetable garden. This is the part that makes most people shudder, but you can’t catch diseases you don’t already have, and after this amount of time, there’s nothing pathogenic left, so there’s nothing to fear. If you still have fears, use it for flowers, trees, and shrubs.
Apart from human waste there are other things you can compost as well Green things are best these include:
Animal manure with straw
Brussels sprout stalk
Fruit peelings and pulp
Old bedding plants
Soft prunings and plant debris
Tea leaves and bags
Vegetable peelings and pulp
You can also use Browns but these can produce carbon and take longer to break down and rot.
Slower to rot, provide carbon & fibre and allow air pockets to form.
Corn starch liners
Used kitchen paper
Vacuum cleaner contents
Certain things should never be placed in your bin.
Meat and fish scraps
