SHIT MATTERS BUT HOW YOU PROCESS IT MATTERS MORE. Efrim Energy is an environmentally-sound waste treatment business with a co-product called electricity. Using a novel drying process that does not require heat or generation of methane, Efrim converts cow manure to highly efficient biomass fuel for non-stop, green power generation. We unlock up to five times more energy from the same amount of input manure than any other waste-to-energy system.
