The Real Know How

Laura Allen’s Composting Toilet System

Laura Allen shows us her composting toilet system. She is using a toilet that separates urine and feces, with feces being deposited into bins under her house. From there she dumps it into a sealed compost bin for a year, after which it has broken down into an inoffensive compost that she uses in her garden.

On the tour of her bathroom, she also mentions that her bathroom sink directly waters plants in her garden with its greywater (since it’s a sink, in this case, greywater is likely soapy water).

I understood that the composting process breaks down any pathogens that might be in the feces, but wondered whether substances like any drugs the person may have been taking would remain.

I also would have loved to see where the urine was diverted and what she did with it.
