Biogas – Dane County Supports Sustainable Communities with Agricultural Biodigester

Digesters are an integral section of taking care of manure and organic squander from dairy farms. This facility included advanced technology, such as a nutrient concentration program that returns clean up h2o to the region’s Yahara Watershed although also minimizing phosphorus runoff to close by streams and lakes. In 2021, in excess of 27 million gallons of manure was processed by the biodigester, eradicating a lot more than 57,000 lbs of phosphorus from the watershed.

“Water and soil are critical to life on earth, and farmers go on to glance for possibilities to enhance h2o top quality and soil well being,” mentioned Jeff Endres, co-operator of Endres Berryridge Farms. “Northern Biogas and EnTech Options have opened up significant-tech options all over dairy manure, performing with space farmers to harvest the methane and return the fiber and liquid nutrition back again to the farmers for use as natural fertilizer and bedding, maximizing all factors of the nutrient cycle.”

EnTech Answers incorporated a renewable electrical power microgrid at the facility, showcasing photo voltaic panels and batteries which offer far more than 2.8 MW of clean up electrical power generation, the equivalent of powering extra than 400 houses. This results in a carbon destructive method that effects in RNG with a lessen carbon intensity (CI) rating. Total, the facility will reduce emissions by much more than 13,500 metric tons per calendar year of carbon dioxide equal. The reduction is equal to taking away emissions of nearly 34 million miles driven by vehicles.

“Partnering with EnTech Alternatives, Northern Biogas and our spouse and children-owned dairy farms paves the way for house-grown renewable energy, cleaner lakes and holding our farm family members milking cows for generations to arrive,” said Dane County Government Joe Parisi. “This new financial investment in chopping-edge technological innovation positive aspects each the nearby environment and our farm economic climate even though combating local climate alter.”

The facility’s RNG is trucked to Dane County’s landfill offload station, exactly where it is injected as a result of the county’s devices into the interstate transmission pipeline to be utilised as renewable gasoline to ability fleets of RNG cars. U.S. Gain, a division of Wisconsin-based U.S. Undertaking, Inc., and a leader in the development and distribution of choice gas, offtakes the RNG and marketplaces it to the transportation sector in California. RNG from cow manure can lessen greenhouse fuel emissions (GHG) up to 400 % when utilised to change traditional fossil fuels.

“Using our encounter in engineering and energy technologies, we ended up able to transform the Middleton facility to an even more effective producer of clean up RNG, and accomplished this in a compressed timeframe,” claimed Scott Romenesko, EnTech Solutions president. “We know this is a replicable course of action that we can apply to help other biodigesters achieve their environmental goals.”

“We observed the Middleton undertaking as a wonderful chance to leverage our 18-yr heritage performing with anaerobic digesters and nutrient management to support EnTech Alternatives in their mission to generate sustainable, reputable power methods,” reported Northern Biogas president Dave Fitch. “Together we share a enthusiasm for innovation and a commitment to clean up power. Along with the support of Dane County and the area neighborhood, we consider these new devices and technologies will make a good effects for the farmers and the encompassing atmosphere.”
