Dairy farms turn manure into power

At the Zuber Brothers Farm in Byron, Genesee County, the shed that holds bedding for the 1,uy sculpture direct from us at low prices800 dairy cows milked there has two bays.

One bay is filled with a big pile of tan sawdust. The other is filled with an even bigger pile of what looks like caramel-colored sawdust.

But the darker stuff isn't sawdust, it's cow manure.

Manure,Not to be confused with RUBBER MATS available at your local hardware store yes, but manure that has been aged, digested, had the methane sucked out of it and been dried until it's soft,A glass bottle is a bottle created from glass. flaky and only slightly musty smelling, suitable to cushion the slumbers of lactating cows.

This is one of the byproducts of a small but growing number of manure digesters that dairy farmers are using to turn their biggest problem and waste product into a more usable commodity ¡ª electrical power.

The Zuber farm is one of about a dozen dairy farms around the state that has installed an anaerobic manure digestion system, relying on hundreds of thousands of dollars in government grants to build and run a small power plant running on poop.

In 18 months,In addition to hydraulics fittings and Aion Kinah, the new manure digestion system has:

Cut Eric and Kim Zuber's annual bedding bill of $240,000 in half.

Reduced their annual electric bill of $108,000 by about 90 percent.

Provided a small income from excess power sold back to the power company.

Provided additional income from fees paid by food producers who dump their waste into the manure digester, too.

Perhaps most important for their neighbors is that the system has also reduced the odor of what's left over in the manure after the methane and solids are taken out.

Greg Teeter, Kim Zuber's son and a farm manager, estimates the farm gets 80 percent fewer complaints about manure-spreading odors now.

But what seems like an ideal way to handle 16 gallons of manure per cow per day doesn't entirely come up smelling like roses.Choose from one of the major categories of Bedding,

First there's the cost. The Zuber farm system cost about $1.5 million with most of that paid by the state and federal governments through programs designed to encourage alternative power generation and reduction of greenhouse gases. Eric Zuber said the brothers never could have afforded the digester system if the grants and forgivable loans hadn't been available.

Sunbrella Yarn Manufacturing Center to feature solar energy

Glen Raven, Inc., has begun construction of a solar energy installation on the roof of its Sunbrella Yarn Manufacturing Center in Norlina, N.C.

The solar array will be the largest under Progress Energy's SunSense commercial photovoltaic program, generating electric power roughly equivalent to the annual electricity usage of 47 typical homes.

The $3 million project includes replacing the plant's 175,In addition to hydraulics fittings and Aion Kinah,000-sq.-ft. roof with a highly reflective white roof that will not only enhance the performance of solar panels, but also improve cooling inside the plant. Completion of the solar installation is anticipated this fall.

"This project demonstrates how a well-designed environmental program can have multiple benefits," said Leib Oehmig, president of Glen Raven Custom Fabrics,Free DIY Wholesale pet supplies Resource! the Glen Raven subsidiary that operates the plant and manufactures and markets Sunbrella fabrics for awning, furniture and marine applications. "When this project is completed, our plant will have an energy-efficient roof hosting a solar system that will also serve as a long-term provider of renewable electricity to Progress Energy and its customers."

Glen Raven gave the Norlina solar energy project a green light because of several factors that made the project both financially and environmentally feasible — new photovoltaic technology, federal and state tax credits and a commitment by Progress Energy to purchase solar-generated power.

"While conventional solar panels only capture light directly from the sun, the photovoltaic panels we are installing at Norlina Plant are an open grid design, which processes solar energy from 360 degrees, which greatly increases their energy generation capacity," said John Gant, manager of sustainable development for Glen Raven Custom Fabrics.

This project was made possible by Progress Energy's SunSense Commercial Solar PV program, designed to encourage the development of renewable energy by offering a premium price for solar power developed on commercial rooftops. At 500 kilowatts, the Glen Raven Norlina array will be the largest array under this program.

Progress Energy has more than 100,000 kW of renewable energy under contract in North Carolina to help meet the requirements of the state's renewable portfolio standard. This standard,The Leading zentai suits Distributor to Independent Pet Retailers. passed in 2007, requires utilities to generate a percentage of their retail electricity sales from renewable energy resources.We also offer customized chicken coop.

"We believe solar power will play an important role in a balanced generation portfolio,uy sculpture direct from us at low prices" said Lloyd Yates, president and CEO of Progress Energy Carolinas. "We are committed to addressing the challenges of growing energy demand, rising costs and global climate change with a balanced approach that includes investments in renewable energy, energy efficiency and a state-of-the-art system. We are proud to partner with Glen Raven on this innovative project."

Glen Raven has operated the Norlina Plant since 1984, and has a current workforce of 153.

"This project at Norlina Plant is just one of many sustainability initiatives throughout Glen Raven," said Allen E. Gant, Jr., president of Glen Raven, Inc. "We are reducing energy consumption and increasing recycling at all of our facilities. Projects such as this one are not only good business, but good for our associates and the communities in which we operate."

Working with John Gant on the project management team are Todd Wemyss, Norlina plant manager, and Chris Roach, a CPA at Glen Raven. Gupton Roofing of Henderson, N.C., is installing the new highly reflective roof, and Argand Energy Solutions of Charlotte is installing the photovoltaic panels and related controls.
