Blue Sphere has recently signed a definitive project agreement for the North Carolina and the Rhode Island projects, which together have a potential to generate $150m over 15 years.

The project integration company is in the process of finalizing feedstock agreements, land, debt and equity financing and tax credit monetization for the two projects.

Blue Sphere CEO Shlomi Palas said that the company has entered the waste-to-energy market in the end of 2011 and the two projects were the first being implemented by it. The company has options for 10 more such sites in the US.

"Our joint venture with Biogas Nord gives us the technological know-how and advantage in implementing any waste to energy project wherever it may be located.

"Biogas Nord is also training us in service and maintenance, so, after we are comfortable with our skills, we will enter into this business, as well," he said.
