Ruihong Zhang Ph.D.
Professor, Department of Biological and Agricultural Engineering, UC Davis
A Professor in Department of Biological and Agricultural Engineering at the University of California, Davis.
She teaches and conducts research in the area of Bioenvironmental Engineering. Her current research is
focused on conversion of organic wastes to biofuels and biobased products, improvement of energy
efficiency in wastewater treatment, and air quality control. Example research projects include (1)
developing advanced anaerobic fermentation and digestion technologies to produce biogas fuel
(methane and hydrogen) and liquid fuel (ethanol and biodiesel) from food and agricultural wastes; (2)
Developing integrated, energy-efficient wastewater treatment systems for dairy farms and food
processing operations; (3) reducing air emissions from waste management systems. Dr. Zhang has over
160 scientific publications and 4 patented inventions. She has served as an expert on many international
and national technical committees and is a member of editorial boards of two scientific journals.
Dr. Zhang is the director for UC Davis Biogas Energy Project, which is sponsored by the alliance between
UC Davis and private industry. The Biogas Energy Project is for research and demonstration of new
advanced anaerobic digestion technologies to convert a variety of organic wastes into biogas fuels and
other valuable products. Dr. Zhang received New Holland Young Researcher Award from American
Society of Agricultural and Biological Engineers in 2003 and Environmental Award from US Environmental
Protection Agency in 2007.

1) About Us
2) Our Team
To meet the demands of a growing company, Onsite Power has expanded its top management. Because of the nature of
its core business and the significance that Onsite Power’s technology may have in the market, Onsite Power continues to
attract high caliber management.
OPS’s management team consists of members whose backgrounds are in engineering and business administration, with
combined experiences in the electrical Industry, digestion technologies, process engineering, construction, financial and
consulting, and in areas such as corporate development, production, process engineering, maintenance, logistics,
controls technology, quality assurance, project management, energy and cost accounting, biological and engineering
research and development.
|Onsite Power Systems, Inc. (OPS) is a privately held organic resource recovery company,
anchored by a team experienced in this sector with the objective of changing the way the
world is able to create energy from various problematic agricultural and organic waste
OPS provides advanced Anaerobic High Solids (AHS) digester technologies and process
expertise to provide cost effective and economical solutions to organic waste recovery.
These advanced technologies will produce renewable fuel and energy at a lower cost than
that of competing fossil fuels.
The OPSThe OSP Mission Statement promotes the adoption of organic waste recovery through renewable AHS digester
technologies as a method to increase energy security and environmental sustainability. OPS continues to raise public,
government and regulatory agency awareness and acceptance of available biofuel, biomass and biogas technologies
through the demonstration and education of organic waste recovery for renewable energy.
At OPS, corporate social responsibility will continue to be an integral part of our purpose as a company and is reflected
in our mission to bring great people and great organizations together. We recognize the importance of being a good
corporate citizen and contributing to the overall social environment of the communities in which we operate. That is why
we will continue to make every effort to make social responsibility a main part of our business strategies through various
educational, community outreach and “Give Back” programs.
Over the past 5 years OPS has conducted an extensive education and outreach program. In October 2006, OPS hosted
an official startup and dedication ceremony at the UC Davis commercial demonstration digester facility. Since that event,
OPS has hosted numerous tours and events for multiple sectors including governmental agencies, municipalities,
commercial companies, educational and international dignitaries totally over 1,000 people per year. In addition to the
digester facility tours and events, members of the OPS team have presented at multiple conferences and seminars.
Educational opportunities included both national and international scholars and researchers, both touring as well as
working with the facility. Additionally, Dr. Zhang and other professors from the University conducted several class
sessions at the facility. OPS management participated in a number of these class sessions providing the private industry
perspective on developing, demonstration and commercializing these technologies.
Through these initiatives, we will continue to make it a priority to collaborate with other companies and organizations,
locally and nationally, that share our common social responsibility goals.
The OPS Value Proposition: Our competitors have spent hundreds of millions of dollars developing digester
systems but still do not provide efficient and economical solutions for organic waste recovery. The proprietary
technologies and processes developed by OPS are radically different from the competition and the following
are just some of its differentiating characteristics:
• Capable of being mass produced – Most sub-systems can be prefabricated
• Affordable - Utilizing off-the-shelf components
• Modular - Non mechanical in design and “cookie-cutter” designs
• Scalable - Process offers digester system size flexibility
