Dear Emmanuel,
Dear all,
In Belgium, we are a group aiming at developing ecological sanitation practice. The main problem we have is the absence of legal output for the products of sanitation. In compost-treatment plants, people in charge don't want fecal matter because of hygiene risks. A project to make safe compost based on fecal sludge and/or product from vacuum toilets to be spread on organic matter like straw is being planed with university research, but funding is still missing.
No legal framework exist for urine application but it would fall in the sludge legislation, wich means that the products have to be regulary tested, so money and big infrastructure are needed, wich is difficult for small-pilot-project.
It seems to be the same in several european countries. As far as I know, urine application exist in Germany only for exceptional research goal (is there any hope that the project would lead to a broader legal application of urine in Germany? Are there relevant outputs that would lead to economical treatment of urine?), and in Sweden under fecal sludge legislation.
Without legal output, there is not much hope of development. Are there any people working in ecological sanitation in EU here who would have hope of development? Is there yet a group thinking about SuSan in Europe? Or the only way would be to enhance the existing infrastructure to recover P in sludge or even in the ashes? Separation is good in theory, but can it be put into practice at large scale in Europe?

Thanks in advance for all relevant information,
