Project in Paris 14e with 137 apartments collecting diverted human urine from Ultra Low Flush Diverting Toilets to be used as fertilizer for farming 

One more very interesting urban ecology sustainable project closing the nutrients loop in sanitation. We at BACKLUND ECOLOGY would love to participate and to contribute with our expert knowledge from 30 years of projects and with our ultra low flush diverting toilets used in our many projets in and outside Copenhagen.

2017 - 2020 Sweden, Stedsan in the Woods, Bohult Hyltebruk

It started having the pleasure of advising about sanitation and toilets and delivering for testing first a Separett Villa 9000 and the ultra low flush EcoFlush toilet to iconic Flemming when he was running his restaurant Stedsans on the rooftop farm ØsterGro in Copenhagen Denmark. Following his dreams Flemming and Mette found the most wonderful place out in the swedish woulds at a lake. 

Sara and I have so much enjoyed our continuing discussions about local metabolism and implementing diverting waterless toilets in wooden huts for guests in the great wooden cabins enjoying wonderful meals in the restaurant.

Flemming finally decided to implement 18 Separett diverting waterless units as a part of the recycling system.

2020 - 2021 Saga Space Architects LUNARK MOON HABITAT project Denmark, Greenland

Advicing Sebastian and Karl-Johan from Saga Space Architects about sanitation and their toilet solution in the LUNARK moon habitat has been such a pleasure. Visiting them building the moon habitat in Copenhagen to test and compare Separett Villa and Separett Weekend was so interesting.
