Mass Dairy Farmers Use Food Waste & Manure to Generate Renewable Energy
Local farms in Massachusetts are producing their own renewable energy, and they're doing it while diverting food waste and dropping their carbon footprint at the same time. How? By utliizing anaerobic digesters, produced by Vanguard Renewables.
The simplified version is that the process takes the potential energy in both food waste and organic waste (like cow manure) and converts it into biogas that is used to reduce energy costs, reduce methane emissions,eliminate food waste, generate heat, and offset carbon emissions.
Massachusetts implemented a ban in 2014 on disposal of commercial organic wastes by businesses that dispose of more than a ton of organic waste per week. Prior to the ban, this type of waste was the second highest contributor to landfills, so the State mandated that instead of being disposed of, they had to be recycled.
The solution that arose in the form of waste to power anaerobic digesters is pretty ideal - it allows not just farms to upcycle their waste, but also helps food processors, supermarkets, and even fast food restaurants by opening up an avenue for food related industries to dispose of waste economically and in a way that is hugely beneficial from an environmental standpoint.
I wrote an article for Oil & Energy online that goes more in depth into how the process works and the benefits - you can read that article in its entirety here: Farm to Grid
