Nrgtek Signs Sanitation District Contract

Looking good and keeping clean do not always go hand in hand. When siloxane, a compound used in lotions and cosmetics kept clogging up their power generators, the Ventura Regional Sanitation District turned to Nrgtek for a solution. Nrgtek’s engineering team tackled the challenge and developed a siloxane sequestration technology that captures siloxane by converting it from a gas into a non-volatile liquid, reducing the amount of siloxanes in landfill gas from 40 ppm to less than one ppm.

Thanks to this innovative clean technology solution, Nrgtek recently signed a $365,000 contract with the Ventura Regional Sanitation District. As part of the contract, Nrgtek will install a siloxane sequestration system capable of treating 1,000 standard cubic feet of gas per minute at the Toland Road Landfill in Ventura County.

“We were approached by the Ventura Regional Sanitation District to come up with a new technology for removing siloxanes because their current activated carbon method was not doing a sufficient job,” said Subra Iyer, President and CEO of Nrgtek. “Also, the cost of using the activated carbon system was almost $15,000 a month. We wanted to see if we could help them reduce their monthly costs and achieve the level of siloxane removal needed to keep the micro turbines in their power generator clean.”

As trash anearobically decomposes at landfills, released methane and carbon dioxide gases are collected, and the methane gas is converted to power. Siloxane is a non-toxic compound used in many personal care products to make creams thicker, but over time siloxanes vaporize in landfills. As siloxane gases are exposed to oxygen in power generators, they convert to a solid sand-like material, which damages heat exchangers, turbines, engines, cylinders and spark plugs leading to shorter mechanical life spans for many generator parts. The use of siloxanes is increasing about 10 percent a year causing bigger and bigger challenges for landfill operators.

Once it’s installed at the Toland Road Landfill, the Nrgtek siloxane sequestration system will remove more than 99 percent of the siloxanes from landfill gas, prevent deposits from building up in the power generator and greatly reduce maintenance costs. While other siloxane removal systems are cumbersome, expensive and ineffective, the Nrgtek system is small, economical and highly effective. Additional applications for the Nrgtek system include cleaning digester gas, which is a similar gas byproduct produced at wastewater treatment plants.

“Many people don’t realize that the methane and carbon dioxide gases captured at landfills and waste water treatment plants produce five times as much power as all the solar and wind energy produced in the U.S combined. Nrgtek’s siloxane sequestration system keeps this renewable source of energy running smoothly and greatly benefits landfill operators who have been spending hundreds of thousands of dollars on removing siloxanes,” said Stan Tomsic, Executive Director for PortTech Los Angeles. “We are looking forward to working with Nrgtek to promote this clean technology and help them sign more contracts similar to the Ventura Regional Sanitation District deal.”
