A process to transform solid waste into fuel by adding water and heat to provide no more than 350 BTUs/lb of the weight of the solid waste for no more than 85 minutes. Such a process transforms the solid waste into fuel in a process time of not greater than 85 minutes. The system uses a pressure vessel; a condenser tank to permit selective addition of water to and evacuation of steam from the vessel; a heater to increase the temperature of the vessel; a vacuum pump to selectively reduce pressure within the vessel and to help evacuate steam from the vessel to the condenser tank; and a water pump to selectively add water from the condenser tank to the interior volume of the vessel. A method for converting solid waste into fuel includes loading the solid waste into a rotating pressure vessel and transforming the solid waste into fuel by adding water; reducing pressure; adding heat; and then evacuating steam. The contents are evacuated from the pressure vessel. At least some of the contents are fuel.

A process for enhancing the magnetic susceptibility of plastic materials facilitates the separation of those materials to enable recycling. The invention includes the plastic which is formulated with the enhancement materials, typically magnetite or ferrous particles in amounts of between 0.1 and 5% by weight; a method of making the plastic and a method of separating the plastic material from a waste stream.
