    “Making It” provides all the tools you need to build a self-sustaining and productive household. Projects are divided into five categories based on the amount of time they take: day to day, weekly, monthly, season to season and big projects you’ll need to do only once. You’ll build all the skills you need to do everything from making your own laundry soap to becoming a beekeeper in your backyard.

    You’ll need a constant supply of sawdust to use as cover material. Ask around at wood shops and lumberyards for sawdust. Don’t use sawdust from chemically treated lumber, fiberboard or plywood.

Building a Dry Toilet

Preparation: 1 hour
Waiting: 1-2 years

Flush toilets take two valuable resources, clean water and nitrogen-rich human waste, and combine them to create a problem: sewage. Dry or “humanure” toilets combine sawdust and human waste, which is then composted to make soil. It’s a simple, elegant system that follows nature’s dictate that there is no such thing as waste.



A dry toilet uses no water, power, or chemicals, and it doesn’t require plumbing lines or septic tanks. This makes it perfect for off-grid living as well as situations where plumbing is not available. It's a convenient way to add an extra toilet to any house.

We’d be lying if we said it does not seem strange at first to use a toilet with no water, but you do get used to it quickly. If you’ve been raised with flush toilets, your most basic impulse is to make your waste vanish. Pronto. However, once you grasp the indisputable logic of the system, know firsthand that it does not smell, and have seen the contents transformed into sweet-smelling, clean soil through the power of composting, you'll never look at flush toilets the same way again.

Does no one at Mother Earth News (or it's contributors) own a camera? Almost all the 'how-to' articles are seriously lacking in pictures. (The things that are supposed to be worth 1000 words). A recent article on a bicycle powered band saw had one single picture. And it wasn't even a picture of the completed product, but rather, a bicycle wheel. I got a lot out of that picture. This article also would be 100 times better with some pictures to go along with the steps. That way the reader wouldn't be left trying to figure out exactly what the writer is trying to convey. It's not that hard to take or post digital pictures. Due to the lack of pictures, I'd have to rate most MEN's 'how-to' articles as POOR. Sorry to leave such a negative response, but it's very frustrating for a 'newbie' to try and figure out what a 'pro' is putting in writing some times.
