They waterless separating toilets discussed by the article literally are composting toilets. The difference is they're proposing using the diverted urine to replace more energy-intensive commercial fertiliser production, rather than treating it as the less useful waste byproduct for people's gardens. (That and they're acknowledging that people who haven't chosen composting toilets tend not to like them, because the separating takes some getting used to and if you don't separate urine from faeces the decomposition is much slower and smellier)
