San Francisco Chronicle: Device Makes Turning Human Waste Into Compost Safer

By Stephanie M. Lee in the SF Gate. Original article here. Your toilet bowl may hold the key to replenishing forests, growing crops and saving countless gallons of water. And that's why Gary Andersen, a senior scientist at Lawrence Berkeley National Laboratory, is so excited about poop. Andersen has invented a device that tracks the decomposition of compost made of human feces, a function that he says could help improve environmental health all over the world. In earthquake-ravaged Haiti, the technology is being used to monitor sanitary waste in an effort to accelerate the production of disease-free, nutrient-rich compost for agriculture and ...

Notre Dame Student Finds That SOIL Compost is Pathogen Free

John Strutner from the University of Notre Dame recently traveled  from Indiana to Haiti in order to collect samples of SOIL’s compost and test it for fecal pathogens.  SOIL assiduously follows international public health standards for the composting of human waste as it converts over 5,000 gallons of poo per week into nutrient rich fertilizer. Now thanks to John’s study, we have evidence that  SOIL’s efforts are paying off.  John found that pathogenic material present in the human waste that SOIL freshly collected from ecological sanitation toilets around Haiti was no longer present after going through the composting process. As John ...
