  8. VOC to VOE

  9. Customer Feedback ES1: “Mitigate risk of falling might also be related to hole size/shape, not just support weight ... keep children from falling through?” Constraint 2: “don't specify locally available. I want them to compare local and manufactured materials.” “… not sure you need CN9 if you have CN12.” “CN5 could specify ‘by 4 people or less’ to combine with CN13, CN19.” “CN21 should have higher value/weight, maybe even 9...as this is the area where the team will need to be most innovative.”

  18. Customer Feedback ES3: "contain pathogens, do not allow unsafe leakage of untreated wastes." – “…and I don't want to limit their creativity.” ES7: “... Preferably, you wouldn't have to stir.” ES8: “the spec should be higher if 0.5 L is the volume of the human waste… will be mixed with … cover material” ES9: “I'm not expecting the pasteurizer to make compost … we could possibly approximate with a simpler e coli test.”
