OK, it sounds like what you want to do is to determine the ultimate digestibility of your feedstock -- leaving aside digester design questions for now. That would lend itself to a batch feed process, where you take a measured quantity (& analysis) of feedstock, put it in your reactor (e.g. 2 liter b...

What are your goals, Nathan? I can think of so many possibilities, ranging from basic interest in anaerobic digestion in general, to rigorous testing & measurement of specific feedstocks, feedrates (retention times), design geometry (e.g. single vs. 2-stage) etc. If you are specifically interested i...

How simple can this be? Could we just get some airtight 5 gallon pails with a spigot to a balloon to capture gas for the container? How about using some 2-liter plastic soda bottles? Put them in a heated water bath -- cheap styrofoam cooler filled with water with aquarium heater set to 95degF. At t...

(reply cross-posted from email) Most interesting. On the surface, it seems like a viable idea. I believe it would be quite feasible to digest straw & chaff (wihout actually having done so). The lignin content could be problematic, but the C/N ratio should be excellent -- at least with the addition o...

Most interesting idea, Nathan. With your permission, I'm taking the liberty of cross-posting your email (with links attached), that fleshes out the idea. =========================================== Bob, Here is a simple hypertext outline of the idea I mentioned in the forum post. I had two goals in ...

I don't have a description of the "indoor wetland" portion of the treatment system per se, but do have a more general description of the Bioshelter of which it is a part here.

There are a number of urine-separating toilets on the market, but I haven't personally used any of them to know how they compare.Here is a link to one. And a couple of pictures.

That's an interesting idea. The advantage of the throway liner is relatively little fuss, but disadvantage is that when you do throw it away, it will be pretty nasty, including uncomposted fresh material. I had in mind a more rigid, permanent, cleanable, non-stick (relatively) liner. Maybe 1/8" thic...

While, in general, I applaud your ideas and enthusiasm, I'd add qualifiers to a number of them--if we are talking about real-world feasibility. For example: I'm not sure that zero infiltration is either an ideal or healthy goal, let alone achievable. Exchanging gases with Gaia is not a bad thing, an...

Hi David,
Did you check out my new digester calculator? With it, you should be able to answer some of your questions. To use it, you need to have Java enabled in your browser. If you have trouble getting it to work, let me know.

I finally got a revised on-line design tool working. I still want to do some refinements, and add to the help info, but try this.

After thinking about it a little further, probably regular composting -- i.e. without worms -- might be better. The advantage of worms is that they do the work of turning the pile, to homogenize and aerate it, but the disadvantage is that you can't let the compost get hot enough to kill the pathogen...
