Leading Innovation
Green City was founded in 2009 with the vision of providing a platform for cheap, 100% renewable energy while focusing on our social and environmental commitments as well as the bottom line.

In 2013 “Rafael Advanced Defense Systems Ltd”
Expressed interest in Green City and its board decided to invest in it, since mid 2013 Green City became Subsidiary company of Raphael.
Our R&D team is working tirelessly, together with the team of Rafael, the continue development of other breakthrough alternative fuels as well as the world's most advanced manufacturing processes.

Green City is commercializing rapidly. Our first plant in Jerusalem was operating since August 2011,and since “Rafael” became part of the company, the plant was extended and relocated to Kibbutz Eyn Hamifrats.
We are currently responding to interest from companies and governments from over a dozen countries, with several projects in the pipeline. We invite you to contact us if you have any questions not answered on the website or to explore a business relationship.

»
Fewer Steps Combined esterification and transesterification, no degumming, no wastewater treatment, fewer washes and no final polishing.
