There's always some leftovers or scraps that come out of the kitchen. This should never be put in the trash. It all acts as a food to something else, whether pigs, rabbits, fish, worms, BSF or even your compost pile.
The waste you'll inevitably get from butchering an animal is an invaluable additive to other animals' diet. It can be composted, but why do so when it is so nutritious as a feed.
If you have manure on your property, sooner or later there will be flies. They are one of the most irritating insects (besides mosquitoes) if you let them have their way. There are however many ways to control, and even use, them.
If you are building your bathroom from scratch, you can easily install a solar air vent from the toilet to the outside. The sun will do the work of an extractor fan.
Human manure composts just as well as animal manure. It is a valuable commodity, not something to be flushed away with clean water.
Making your own composting toilet is easy, elegant and requires no plumbing. You can design it however you like, so long as it remains practical.
You can make methane, or biogas, at home by adding human and animal manure into a methane digester. The gas can be used for heating, cooking or any other way in which you would use propane.
Paper should never be thrown in the trash. It is organic and can safely be burned, composted, or shredded and reused.
