Dr. Joshua Lewis Rapport, Technical Advisor

Dr. Josh Rapport honed his professional, leadership, engineering, and R&D experience in industrial bio-processing facility design, construction, and operation over the last two decades. He holds degrees in Biology, International Agricultural Development, and Biological Systems Engineering as well as two patents and is a leading engineer and researcher in the fields of biofuels, nutrient recovery, life-cycle assessment, and bioprocessing. Most recently, he launched his own independent consulting company, Rapport Renewables (, capitalizing on his extensive industry experience.

Josh directed corporate R&D and process engineering efforts at two different companies for over 10 years, successfully demonstrating commercial viability of high-solids AD of food waste and low solids AD of dairy manure for conversion of organic waste to heat, power, and vehicle fuel. He has used his expertise to build and lead teams to integrate novel pre-processing, digestion, and gas conditioning systems, to model and design key components, and to develop efficient control and data monitoring systems. Dr. Rapport directed research and development efforts for new fertilizer and soil amendment products from digestate materials. He patented and tested novel commercial fertilizer production processes and has worked with farms and university researchers to test various digestate based fertilizer products in commercial agriculture settings.

Dr. Rapport has designed, built, commissioned, and operated three commercial food waste digesters, and he helped operationalize over 15 new dairy manure digesters producing renewable natural gas for pipeline injection. He has acquired and managed over a dozen grants and partnerships with the nation’s leading organizations, including Argonne National Laboratory, Lawrence Berkeley National Laboratory, the California Energy Commission, CalRecycle, the California Department of Food and Agriculture, the New York State Energy Research Development Agency, the US Environmental Projection Agency, and the US Department of Energy. He has also provided technical assistance to companies making green ammonia, recycling residential wastewater, and methanol.

Dr. Rapport discovered his passions for sustainable agriculture and biomass energy while serving in the US Peace Corps in the South Pacific from 2000 – 2004, where he helped local youth groups make biodiesel from coconuts, compost, and small commercial egg production projects.
