It's a bit worrying that they talk about burning human shit to get phosphate when you can just compost it.

- seunosewa 7y agoI guess it's because composting doesn't guarantee the destruction of pathogens.
- Nasrudith 7y agoYeah human waste fertilizer sounds like a very good way to get outbreaks.
- robocat 7y agoThe issue is probably all the contaminants in human poo, especially medical: anti-bacterials, hormones, radioactive tracers. Maybe it isn't so much purifying the phosphate that matters, but removing components that would be bad to recirculate into our food chain.
- emj 7y agoHigh temperature composting deal with the most common problems anyways, and you preserve the nutrients rather than burn them up. The biggest problem is how bad water waste management systems are at producing fertiziler, the wide spread idea that it's ok to pollute our waste water with what ever, making it unusable for composte is not healthy. I do not think burning it can solve more than a tiny part of that problem.
