US based Changing World Technologies claims they have perfected a Thermal Depolymerization Process to convert any carbon-based material into water, gas, oil, and minerals.
They have experimented with various feedstock including tires, plastic bottles, old computers, cornstocks, sewage and turkey guts, each producing varying amounts of the output materials. They are about to open a large plant next to the Butterball plant in Carthage, Missouri, which is expected to digest 200 tons of turkey guts per day.
