2018 CVM News: Dairy barn implements poop-to-power system

Abstract

This news item from the Cornell Chronicle is about: Cornell’s College of Veterinary Medicine Teaching Dairy Barn – home to 200 cows – has installed a state-of-the-art system that separates manure from sand bedding material, providing clean bedding for the cows and creating muck perfect for making electricity and heat. Dairies also use sawdust, wood chips or straw as bedding material, but sand reduces potential bacterial growth while maximizing cow comfort, said Paul Jennette, the veterinary college’s director of biocontainment operations.
