ETV CANADA

Environmental Technology Verification, Canada has evaluated testing of the Marvel at the University of Guelph. They have authorized Global Earth Products to use the ETV Canada logo in our marketing efforts. ETV Canada determined a 65% reduction in greenhouse gas emissions when utilizing liquid hog manure with the Marvel system, when compared to in-ground concrete storage with a lid.

As you can surmise, results would be even more dramatic if the spreading of the manure on farm fields had been included in the testing.

Greenhouse gas emissions (nitrous oxide and methane gas expressed in CO2 equivalents) during the process are reduced by 64% in comparison to a conventional system of liquid/slurry manure management by inground, concrete lined tank storage (as defined by the International Panel on Climate Change1); and,
