Culhane innoculates the ARTI side of the Solar CITIES IBC/ARTI hybrid with cow manure from the Kibbutz

January 16, 2014

We built this Solar CITIES IBC/ARTI Hybrid Biodigester system on January 15th at Kibbutz Lotan after Culhane field tested the new design early in the fall at Mercy College. The new idea was to use buckets for the feed in and slurry out, simulating a Puxin or fixed dome digester using water displacement to allow for some gas build up in the IBC and creating water pressure to force the gas out. It also gives an ability to easily pour food waste in, acting as a “mega funnel”.

The digester was built in a workshop led by Culhane Cicelsky and Kaplin with the Kibbutz Lotan Green Apprenticeship Students and with students from Envisaj Mercy, the Mercy College Environmental Sustainability and Justice League from New York, including Green Apprenticeship alum and Solar CITIES Rio partner Leo Adler.

Because of an unusually cold winter in Israel, which included snow in Jerusalem, it took nearly two months for the system to begin producing gas.
