The North East Biosolids and Residuals Association (NEBRA) has unveiled a new website that provides updated data on anaerobic digestion and biogas production at wastewater treatment facilities across the United States. NEBRA says the website, www.biogasdata.org, provides policy makers, market analysts, project developers, and water quality professionals with key information about the potential for biogas production as a renewable fuel. Biogas can be used in place of natural gas in boilers and engines to produce heat and electricity.
The data, which builds on U.S. Environmental Protection Agency (EPA) data, shows that the wastewater solids (sludge) from more than 1,200 U.S. wastewater treatment facilities undergo anaerobic digestion and produce biogas. Almost all of this wastewater biogas production occurs at facilities that treat from 1 to hundreds of millions of gallons per day (MGD) of wastewater. However, two-thirds of these 3,300 major facilities do not send solids to anaerobic digestion and produce biogas. In addition, there are more than 13,000 minor facilities (less than 1 MGD in size), of which only a small number operate anaerobic digesters. With these numbers, NEBRA states there is potential for considerably more biogas production from wastewater.
NEBRA says the use of biogas at wastewater facilities is also underdeveloped: the data shows that one-third of the treatment facilities that produce biogas do not put it to use for energy, and only about 300 use it to generate electricity.
The new website presents data collected over the past year by a team of biosolids and biogas organizations across the country. Seed funding for the data collection was provided by the Water Environment Federation. Funding for the initial website development was provided by Cambi, the New York State Energy Research & Development Authority, and the National Biosolids Partnership, with significant in-kind contributions by project team members, including American Biogas Council, Mid-Atlantic Biosolids Association, NEBRA, Black & Veatch, and 350 Technologies.
“The goal was to develop and present a consensus-driven data set—data that everyone in the field could rely on,” said Lori Stone, Global Practice and Technology Leader at Black & Veatch, one of the principal investigators on the project, in a prepared statement. She said it took hundreds of phone calls to wastewater treatment facilities to ensure the accuracy of the data.
Ned Beecher, executive director of NEBRA, said the new website meets the field’s need for quality, shared data and that he hopes the new central Web-based platform will be expanded and improved over the years.
