Impact Bioenergy, a manufacturer of systems that convert organic food waste into usable energy and fertilizer, unveiled its new anaerobic digester at the Island Spring Organics tofu factory Tuesday.

The project, supported by Gov. Jay Inslee’s Clean Energy Fund, the Sustainable Energy Trust and King County Department of Natural Resources and Parks, is able to derive methane and carbon dioxide from food waste that is broken down by bacteria — the process creates biogas, which can be treated and used to generate energy.
