Summary
part 3 of a 3 part podcast
Paul, Alan, Stephen and Clay continue the discussion about poop.
Alan is interested to see the final output of the composting process.
Paul lists trees that are "poop beasts"- top of the tree list is willow. Grasses also do well and bamboo is an option. Paul has deliberately avoided food plants as an extra layer of safety.
Alan wants to know how well the output would spread over a wide area. Stephen says it would, given the right spreader. Alan sees that as a way of scaling up: it could be used to feed a large area of pasture, and that pasture could feed ruminants.
Paul states that flies and "poop kool-aid" (groundwater contamination) are well controlled in this system, better than in say a sewage treatment plant. He discusses the possibility of a dry outhouse, which could also provide good control of contamination via flies and water if built right. It would have willows planted around it to eat the poop.
Sawdust vs wood ash: either will work but using a mixture is a bad idea as it could result in lye which is potentially dangerous.
Art Ludwig favors mulch pits for gray water systems. If you surround the pit with willow trees it will consume stuff from the pit year round, this would be good for urine processing. Alan comments that in colder regions the pit needs to be deep enough that it can't freeze.
Paul describes the 4 willow feeders at the lab; another is under construction. Clay comments about the indoor installation: it would be nice to have a door to take the buckets out without going through the building. It has solar-powered fan for air flow management. The willow feeders don't smell because the airflow is arranged to flow into them.
The warehouse is a simple building where the cans are stored. The cans are marked with the date when they are put in, so they know when the 2 years are up.
