First Kompogas Plant in the US to be Built in California

The signing of the financing agreement between Japan Bank for International Cooperation and the operating company Kompogas SLO LLC on March 23, 2017 gave the official green light to the construction of a Kompogas plant. The dry anaerobic digestion plant in San Luis Obispo County (California) marks the first project of this kind for Hitachi Zosen Inova (HZI) in the US.

According to the information, the project will be realized in close collaboration between Hitachi Zosen Inova, USA and Zurich, and the parent company Hitachi Zosen Corporation in Osaka, Japan. In addition to engineering, procurement, and construction, Hitachi Zosen Inova and Hitachi Zosen Corporation will also be financing, owning, and operating the plant in San Luis Obispo. Kompogas SLO LLC is thus Hitachi Zosen Inova’s first DBFOO (Design, Build, Finance, Own, Operate) project.

“The 20-year operations and maintenance agreement will enter into force after commissioning in summer 2018”, Hitachi Zosen Inova gave account. “The plant will produce around 2,900,000 Nm3 of biogas and 22,000 US tons of high-grade compost and liquid fertilizer per annum from 33,000 US tons of green waste and biowaste. All of the biogas will be converted into electricity, delivering a power yield of 6,200,000 kWh/a, enough to cover the annual consumption of more than 600 US households. The compost will be sold separately as high-grade fertilizer for farming and residential gardening.”

California’s Initiative

The 75 Percent Initiative launched by California in 2011 has created the framework for the project. This initiative sets out the state’s declared goal of achieving a 75 percent reduction in total waste by 2020. The strategies envisaged for achieving this are recycling, composting/dry anaerobic digestion, and reducing waste at the source. One of the first steps toward achieving this is the removal of biological waste from landfill sites.
