According to Calumet Renewable Energy, this is the first dairy-based biogas to renewable natural gas (RNG) project in the state of Wisconsin as well as the first project in the United States to transport this dairy based RNG using highway transportation. This project collects and purifies raw biogas from 3 local digesters just outside Manitowoc, WI and injects the RNG into a natural gas pipeline. Additionally, raw biogas from two remote digesters/farms is purified at the site, compressed and trucked to their facility outside Manitowoc, where it is decompressed and injected into the same natural gas pipeline. This project is sized to accommodate additional dairies across Wisconsin. They are currently constructing 3 more remote RNG processing facilities, scheduled to be operational in early 2020.

Jordan Dairy Farm Anaerobic Digester
|
Rutland, MA
ABC Members: Vanguard Renewables
Jordan Dairy Farms, located in Rutland, Mass., was the first dairy in Massachusetts to use anaerobic digester technology to blend farm manure, food scraps, and food processing by-products to produce biogas that is converted into power. The digester system, owned and operated by Vanguard Renewables, has been in operation since 2011 and uses approximately 25 percent manure from 350 cows and 75 percent organic food waste. Annually more than 20,000 tons of food waste from food processors and 9,000 tons of manure is combined in a 500,000-gallon digestion tank. Manure and food waste are mixed and microorganisms convert sugars, fats, and other compounds into biogas annually producing more than 7,008 MWh of renewable energy and generating approximately $200 per cow per year in revenue and cost savings for the dairy from power, heat, bedding, and odor-free liquid fertilizer that increases crop yields. The digester offsets 19,779 of CO2 emissions daily.

ABC Member: Hitachi Zosen Inova
Hitachi Zosen INOVA U.S.A., LLC is constructing and will operate a state of the art dry anaerobic digestion facility at the Waste Connections' collection yard in San Luis Obispo, California. The Project will meet California's waste diversion law which targets a 75% waste reduction from landfills by 2020. The project will utilize waste that would have otherwise been deposited into the landfill as feedstock to create biogas through the anaerobic digestion process. Yard and food waste will be the main components of the feedstock. Biogas will then be utilized to create electricity through a co-generation unit. For this project, Waste Connections' collection trucks will back in through roll-up doors and drop organic waste in the receiving area. A byproduct of this process is solid digestate and liquid fertilizer, which will be sold as compost and fertilizer.

Organics to Energy Phase II, Combined Heat and Power and Digester Upgrades
|
North Andover, MA
ABC Members: Waste Management
After the Massachusetts DEP imposed a ban on landfill disposal of source-separated organics (SS0), the Greater Lawrence Sanitary District (GLSD) completed an Organics to Energy Feasibility Study in June of 2013, which found that incorporating SSO co-digestion and biogas fired co-generation system into the District's treatment process would provide a regional solution for organic waste disposal and produce renewable energy (both heat and power) for use at the treatment facility allowing GLSD to be a net zero electric energy user, thereby avoiding over $2.8 M in power cost. A pilot program found that combining SSO with municipal sludge would product 4 times the amount of methane gas than without SSO. The construction project included the installation of a fourth 1.4 million gallon Anaerobic Digester tank, two 120,000 gallon SSO storage tanks, a new CHP building with two 1.6 MW CAT CHP engine generators and electrical switch-gear to allow export of excess power to the electrical grid.

ABC Members: Brightmark Energy, Martin Construction Resource, DVO, Inc.
This is Brightmark Energy's biggest anaerobic digestion project to date. This project is a partnership with farmers who are on the leading edge of sustainability so that they can improve their bottom lines while being good stewards of their local environment. Previously, the anaerobic digesters on these farms produced electricity that was used both onsite by the farms and transmitted to the local electric grid. However, some of the digesters are more than 10 years old, and they had begun to cost more to maintain and operate than they generated in value. After refurbishment work is completed on the systems, participating farmers expect to see drastically greater returns on their digesters, while further minimizing the local environmental impacts of the manure generated by their herds.
