Abstract
A process for the recycling of organic waste including the steps of passing a waste into a first sealed container, introducing an inert gas into the interior of the first sealed container so as to displace oxygen from within the container, heating the interior of the first sealed container to a temperature of between 1,000.degree. and 2,700.degree. F. so as to form a heated gas within the sealed container, filtering the heated gas so as to remove sulfur and chlorine byproducts of the heated gas, and transmitting the filtered gas to a storage vessel. The step of passing includes the steps of storing a liquid waste within a waste container and injecting carbon dioxide into the waste container so as to propel the liquid waste to the sealed container. The inert gas is passed continuously into the sealed container during the step of heating. The inert gas can be argon. The filter can include a sodium hydroxide filter and a chlorine-removing filter. A water filter receives the heated gas so as to remove carbon components of the heated gas.
