From an article by Rick Barrett in the Milwaukee Journal Sentinel:
A group of local businessmen have proposed using a waste treatment facility at the former Maple Leaf Farms in Yorkville to process food waste into electricity.
Maple Leaf was one of the nation’s largest duck farms. It closed in 2008, resulting in the shutdown of its manure-to-energy methane digester.
DF-1 Associates is a group of Racine-area businessmen involved in restaurant grease recycling. They’re hoping to reopen the methane digester and fuel it with restaurant garbage and waste from food-processing plants. The company would make money by hauling away the waste from restaurants and food processors and selling electricity generated from the digester.

From an article by the NEW Air Coalition of Fond du Lac County in the Fond du Lac Reporter:
As cold weather sweeps in, more and more Wisconsinites turn to outdoor wood boilers to heat their homes.
Wood is a renewable fuel, and the operating costs of wood burners often seem lower than natural gas or electric heat. But we often overlook the cost to air quality.
Because outdoor wood boilers burn over long periods of time and can use green or partially dried wood, they can produce 10 times the smoke of other wood-burning heat sources. Burning wood produces more fine-particle pollution than burning coal, says UW-Extension Pollution Prevention Specialist David Liebl. Inhaling fine particles, even over short periods of time, can aggravate lung conditions like asthma and bring on heart attacks or arrhythmia.
At this time, there aren’t many regulations governing residential wood burning. The amount of emissions can vary by the type of appliance, type of wood, moisture content, air damper setting and weather conditions.
Some municipalities have rules on where outdoor wood boilers can be located, restrictions on when they can be used (such as a ban during air quality alerts), or prohibit them outright.
The Wisconsin Department of Health Services has determined that neighboring residents are at risk of adverse health effects if they can see visible plumes or smell the wood smoke.
To minimize the risks, only clean, dry wood should be used as heating fuel. Because price and performance of wood as fuel can vary, residents do not always see the cost savings they hoped for.

From an article by Steve Cahalan in the La Crosse Tribune:
With the flip of a switch Wednesday, a new renewable energy system at City Brewery’s wastewater pretreatment plant began generating electricity from methane gas previously flared off as waste.
The Gundersen Lutheran-owned system resulted from a unique partnership between the health care provider and the brewery.
It is part of Gundersen Lutheran’s plan to lower its energy costs and be energy independent by 2014, through conservation efforts and renewable energy projects.
The brewery project is expected to generate about
3 million kilowatt hours a year, about 8 percent of the electricity used at Gundersen Lutheran’s La Crosse and Onalaska campuses. That also is enough electricity to power 299 homes, Gundersen Lutheran officials said.
With the new system, biogas from the brewery’s pretreatment plant is cleaned by removing water and impurities. What’s left is methane gas that is burned in the system’s engine.
Heat generated from the engine is captured and recycled back to produce heat for the brewery’s waste treatment process.
Brewery waste goes to its pretreatment plant before being sent to the city of La Crosse’s nearby wastewater treatment plant. Gundersen Lutheran officials said Wednesday it’s possible that biogas from the city’s plant also might be used to create electricity in the future.
