- Anaerobic Digester Provides Source for Renewable Natural Gas -

VISTA, CA — July 2, 2014 — Omnitek Engineering Corp.  (OTCQB: OMTK) today announced it has received an order for a 250 kilowatt diesel-to-biogas converted power generator from National Raisin Company, Inc., based in Fowler, California that incorporates Omnitek’s technology for stationary engine applications and provides a clean and economical solution to the agricultural industry in the San Joaquin Valley region of California. Terms were not disclosed. 

The converted engine/generator system will operate as a Combined Heat and Power (CHP) unit, also called cogeneration or distributed generation, and will simultaneously produce two types of energy – heat and electricity – from one fuel source (biogas). The biogas to power National Raisin Company’s electric generator will be derived from an anaerobic digester process capable of producing an estimated 100,000 cubic feet of renewable natural gas per day from the farm’s liquid waste, which is currently diverted to a municipal water treatment facility.  It is estimated that current water treatment costs will be reduced by at least 80 percent, with expectations that water from the anaerobic digester will be recycled and utilized for irrigation of the vineyards – completely eliminating the need for water treatment by the municipal plant, while reducing CO2 and other greenhouse gas emissions in the immediate surrounding area.

The San Joaquin Air Pollution Control District issued the “Authority To Construct” permit for the project, requiring NOx and CO emission levels of 0.15 g/bhp-hr and 5.15 g/bhp-hr respectively -- representing some of the lowest levels for such an installation.

“Combining Omnitek’s technology with the abundance of biogas derived through this innovative anaerobic process offers significant economic and environmental benefits to the agricultural industry.  We are gratified by the adoption of our technology by the National Raisin Company and look forward to additional opportunities in the region, as well as other stationary engine applications for our diesel-to-natural gas technology across the country and the world,” said Werner Funk, president and chief executive officer of Omnitek Engineering Corporation.

He noted Omnitek’s long-time experience in the Philippines with biogas generators. “Industry sources estimate world-wide annual sales for power generators is a multi-billion dollar market, and we believe the utilization of Omnitek’s technology for power generation could evolve to become an important component of the company’s long-term growth strategy,” Funk said.
