Abstract
Apparatus and method for separation, recovery, and recycling municipal solid waste and the like by introducing solid waste materials into a rotatable pressure vessel, rotating, pressurizing, adding pH controlling chemicals and heating the pressure vessel and thus the waste material while simultaneously applying a mixing action to the solid waste material. The addition of a predetermined amount of pH controlling chemicals and the application of a vacuum serve to control the moisture content of the final fine organic portion of the processed material. Organic contents of the vessel are pulped and sterilized when processed to facilitate ease of separation and prepare the resulting cellulose material for use.
Claims12
A method for separation of recyclable waste materials from solid waste materials in a pressure vessel having a chamber to receive and pulp said waste materials therein, said method comprising the steps of:
- introducing a predetermined quantity of waste materials into a process chamber for processing thereof to pulp said waste materials;
- introducing a fluid into said chamber for intermixing with said waste materials for moisturization thereof, said moisture effecting a pulping action on said waste materials;
- adding at least one of a plurality of fluid composition altering substances into said fluid for intermixing therewith to change the chemical composition of said fluid for further enhancing the pulping action of said fluid on said waste materials;
- heating and pressurizing said chamber and thus said waste materials to a predetermined temperature and pressure for processing the waste materials for a processing period lasting a predetermined period of time;
- tumbling said waste materials for mixing thereof during said processing period;
- evacuating said chamber for creating a vacuum atmosphere therein for controlling final moisture content of said waste materials in said chamber;
- recovering said processed waste material from said chamber for classifying said recovered processed waste material;
- and
- separating and recovering recyclable materials from the classified materials.
