Biogas From Mega-Dairies Is a Problem, Not a Solution

At the end of February, the town board of Lind, Wisconsin voted against changing the zoning laws to allow a nearby 600-cow dairy to install an anaerobic digester. These digesters are becoming more common, particularly at larger dairy operations housing thousands of cows, called concentrated animal feeding operations (CAFOs). This is partially because they have been included as a key ingredient in the Biden administration’s pledge to reduce methane emissions in animal agriculture.
At CAFOs, it is common to pool animal waste in one spot, called a manure lagoon. Anaerobic digestion creates a mixture of gases, which can be used for electricity or further processed into fuel for vehicles. The idea is to take advantage of these large quantities of waste to create something useful and reduce methane emissions, helping the climate along the way.
However, that’s not quite how it works out. In Lind, an overwhelming number of citizens showed up for a public hearing to discuss the change—the Wisconsin Examiner reported that there were so many attendees, they exceeded the capacity of the building and the meeting had to be canceled. Community organizers, under the group name Citizens Protecting Rural Wisconsin, argued that digesters aren’t the solution that they seem to be.
A new report by Friends of the Earth US and Socially Responsible Agriculture Project (SRAP) backs up that sentiment. The study suggests that methane digesters create incentives for the growth of industrial agriculture, further entrenching food systems that harm both people and the environment. These researchers, communities and advocates are working hard to resist the greenwashing of this technology—and sometimes they succeed. Vanguard Renewables, the company
