Doug Allard

Chief executive officer, KriStar Enterprises; 360 Sutton Pl., Santa Rosa 95407; 707-524-8181; www.kristar.com

Doug Allard has been on the forefront of controlling storm water erosion since he started KriStar Enterprises in 1993.

As federal and state regulations related to clean water and endangered species protection have increased, KriStar’s line of products designed to keep washed-away pollutants such as sediment and petrochemicals out of waterways broadened. At the height of the construction boom, KriStar had 40 percent market share for stormwater management products such as fiber roll and fabric bag filters.

In 2008, Mr. Allard formed Cudo Stormwater Systems as more water-quality regulators called for construction sites not only to have slower and cleaner storm water flow offsite but also to mimic the hydrological conditions of the site before construction, called low-impact development. Cudo Cube modular underground water-retention products include a tree-box cistern and a system for improving the sediment-sifting action of bioswales. ---Jeff Quackenbush

Lee Bartolomei

President, chief executive officer, Deposition Sciences Inc.; 3300 Coffey Ln., Santa Rosa 95403; 707-573-6700; www.depsci.com

Lee Bartolomei and optical coating company Deposition Sciences Inc. have been working on halogen lighting since the company was founded 25 years ago. Now, Philips Lighting and DSI are working together to meet the challenge of a probable ban on traditional incandescent bulbs.

According to Mr. Bartolomei, halogen bulbs give similar light to incandescent, but they last for two years and are twice as efficient. Also, they don’t contain mercury like compact fluorescent bulbs, making them much safer to dispose of.

Regular halogen lights produce 14 to 20 lumens per watt. Energy-saving halogen bulbs produce 24 to 28 lumens per watt currently. DSI is working to increase that number to 45, which is expected to be the mandated minimum in the United States by 2020.

Mr. Bartolomei, who received a master’s of science in mechanical engineering at U.C. Berkeley and an MBA from the University of Santa Clara, is the founder of DSI and has served as DSI’s president, CEO and chairman of the board since the company’s inception in 1985.

Mr. Bartolomei has 43 years of experience in the optical coating industry. He worked for Optical Coating Laboratory Inc. for nearly 20 years, holding the position of senior vice president of operations before he left to found DSI.

Mr. Bartolomei holds several patents for precision optical coatings, optical components and coating deposition processes. ---Loralee Stevens

Jim Glessner

Founder and chairman, Clean Concrete Technologies; 555 Fifth St., #300D, Santa Rosa 95401; www.cleanconcrete.com

Jim Glessner, 48, and Richard McCabe started Ekocrete in Santa Rosa in December 2007 to develop strong “green” concrete, and early this year they received a patent for low embodied-energy concrete, called CleanCrete.

Certain traditional concrete now can contain more recycled materials such as flyash and aggregate, but reducing the amount of cement has been a goal. Cement manufacturing involves heat and chemical decomposition that releases carbon dioxide, making cement a source of as much as 7 percent of emissions of human-caused greenhouse gases. The CleanCrete mix uses 7.5 percent Portland cement, compared with 12 percent to 17 percent with common mixes.

More than 20,000 bags of the mix are being sold through Buddy Rhodes Concrete in San Francisco, but Mr. Glessner is scoping the Santa Rosa area for a research facility to develop a version for the mass markets and precast concrete factories. This year he expects to hire five to 15 more workers. ---Jeff Quackenbush

Don O’Shei

Chief executive officer, AltaRock Energy; 2320 Marinship Way #300; Sausalito 94965; 415-331-0130; www.altarockenergy.com

Don O’Shei heads up one of the few geothermal companies in the world focused on Engineered Geothermal Systems. EGS involves using high-pressure injection wells to cause fractures in rock 3,000 to 5,000 meters below the surface. Water is circulated through the fractures where it is heated by the earth’s molten core before being pumped to the surface to power turbines.

Unlike traditional geothermal wells that rely on existing sources of water to create steam, closed-system EGS wells can be placed anywhere hot rock can be accessed.

Mr. O’Shei previously served as the co-president and chief operating officer of MidAmerican Energy Holdings Co., and as vice chairman, president and COO of CalEnergy, which developed and built power plants, including geothermal projects, in the U.S., Asia and Europe. ---Loralee Stevens

Terry Pfaff

President, chief executive officer, EDC Technologies; 50 Executive Dr., #A, Rohnert Park 94928; 707-829-8011; www.savegas.com

Terry Pfaff, 56, started EDC in San Jose in 1984 to develop systems that allow companies to manage energy use, primarily of natural gas, across a number of facilities. The company relocated to Sebastopol in 1989 and expanded to Rohnert Park last year.

Though the company has supplied systems to PG&E customers over the years, EDC currently has contracts with San Diego Gas & Electric and Southern California Gas to supply control systems to the lodging and senior housing providers. These installations often lead to installations elsewhere in the end users’ facilities nationwide, according to Mr. Pfaff.

Growth in work has increased steadily, particularly in the past four years, and he expects it to continue for the next two years. The greening of business has propelled demand for EDS’ tools and services, as has the growth of Internet-linked “smart” building management systems. EDS won the smart power category in the 2006 Clean Tech Open competition.

“A lot has been spurred by the economy, but for the most part our customers do not buy into it because it’s green,” he said. “It is a tool to better manage properties and increase property values overall.” ---Jeff Quackenbush

Daniel Wickham, Ph.D.

President, SludgeHammer Group; 336 S. Division Road, Petoskey, Mich.,49770; www.sludgehammer.net; 707-874-9298

West Sonoma County resident Daniel Wickham, 64, launched SludgeHammer compact alternative wastewater system with Buzz Jenks in 2003. Company sales, now managed in Michigan, have expanded to the point where half come from international projects, such as a 400,000-gallon-per-day wastewater plant to be installed at a commercial facility in Libya.

However, the increasing number of failing North Bay rural septic systems and limited number of affordable alternatives as well as decreasing funds for municipal systems is widening the local market for alternative treatment systems, according to Mr. Wickham. The device has garnered recent certifications and code listings from the International Association of Plumbing and Mechanical Officials, NSF Foundation and International Maritime Organization.

Dr. Wickham earned his doctorate in marine ecology from U.C. Berkeley in 1979 while working as an ecology researcher for 20 years at the U.C. Bodega Marine Laboratory. During that time, he experimented with bacteria used to clean up petroleum spills. Isolating a strain that works on household sewage led to the creation of the Pirana compact treatment system with a group of Sonoma County partners who have since formed their own companies.

Dr. Wickham’s name is on three patents for on-site wastewater treatment and two more are pending. The SludgeHammer system recently was adapted for wine industry wastewater. ---Jenna V. Loceff
