A method for processing municipal waste substantially reduces the volume of material to be disposed into a landfill by increasing the volume of materials of value collected from the municipal waste and by composting the remaining materials to create a salable product. The process includes the removal of materials of value by magnetic devices to extract ferrous materials, by an air classifier to extract light plastic materials, by an eddy current mechanism to extract aluminum materials, and by a plastic sort mechanism to extract large plastic materials. Composting can be accomplished with a composting vessel that is located in the process either before the materials of value are removed or afterward. A grinding of the materials before a final screening allows the commercial grade compost to be separated from the materials that are to be sent to the landfill for final disposal. An alternative embodiment of the process utilizes a steam pressure vessel to disintegrate the waste material and to destroy any pathogens before materials of value are removed and the small and fine materials are composted. Large materials can be gasified to create heat energy for use in the steam pressure vessel.

An alternative embodiment of the process heats the waste material before processing by utilizing a steam pressure vessel or an autoclave to disintegrate the waste material and to destroy any pathogens before materials of value are removed. Large materials can be gasified to create heat energy for use in the heating process. Static pile disintegration of the initially shredded waste material will alternatively reduce the volume of the material to be processed.

Method of processing municipal waste

A process for the comminution and dehydration of animal waste and/or parts by feeding the animal waste and/or parts into a cyclonic, dehydrating comminuter facilitates the further processing of the comminuted and dehydrated animal waste discharged from the comminuter. Both the comminuted and dehydrated material and the air flow discharged from the cyclonic comminuter are sterilized to remove pathogens therefrom. The rate at which the animal waste and/or parts material is fed into the cyclonic comminuter. is directly related to the moisture content of the comminuted and dehydrated material discharged from the material discharge opening of the comminuter. Preferably, the moisture content of the discharged material is in the range of 25% to 35% to facilitate the pelletizing of the discharged material after being sterilized. Other precesses, however, can require the drying of the discharged material to about 10%. An air flow control mechanism is provided for the cyclonic comminuter to enhance the ability to control the discharge of air from the comminuter. The control is provided with adjustable vanes actuated from a actuator projecting outwardly from the comminuter to permit an easy adaptation to automated controls to restrict the size of the air discharge opening from the comminuter.

A process for the comminution and dehydration of municipal sludge waste by feeding the municipal sludge waste into a cyclonic, dehydrating comminuter facilitates the further processing of the comminuted and dehydrated sludge material discharged from the comminuter. Both the comminuted and dehydrated sludge material and the air flow discharged from the cyclonic comminuter are sterilized to remove pathogens therefrom. The rate at which the municipal sludge material is fed into the cyclonic comminuter is directly related to the moisture content of the comminuted and dehydrated material discharged from the material discharge opening of the comminuter. Preferably, the moisture content of the discharged material is in the range of 25% to 35% to facilitate the sterilization of the discharged material. An alternative process can be used, however, to dry the discharged comminuted and dehydrated municipal sludge waste material to about 10%, such as by passing the material discharged from the first cyclonic dehydrating comminuter into a second cyclonic dehydrating comminuter until the finally discharged material has a powdery consistency.

A process is disclosed for the separation and recovery of fractional components of used carpet. The nylon fiber component separated from the carpet pieces fed into the cyclonic comminuter are lighter than the other fractional. components and can be extracted from the comminuter chamber through an extraction valve located in the top wall of the comminuter chamber. The nylon extraction valve includes a valve body with an opening extending generally vertically therethrough and a shaft extending therefrom in a horizontal orientation. The valve body is moved to expose the opening to the interior of the comminuter chamber on an intermittent basis to extract accumulated nylon fibers without disrupting the air flow through the comminuter chamber and the associated comminuting operation. Preferably, the valve body is oscillated back and forth, instead of rotated, in order to minimize the trapping of nylon fibers at the valve opening. Preferably, the rasp bars on the interior wall of the comminuter chamber are oriented to deflect air upwardly toward the nylon extraction valve and facilitate the extraction of accumulated nylon fibers.

A process is disclosed for the separation and recovery of fractional components of used carpet. Although the disclosed process is operable with either jute-backed or vinyl-backed carpet, an alternative process is preferred for vinyl-backed carpet to permit the sequential removal of the vinyl backing with most of the fiberglass stabilizer intact. The process includes the chilling of appropriately sized carpet pieces and preferably pre-soaking the used carpet pieces before chilling, followed by the introduction of the pre-conditioned used carpet pieces into a cyclonic comminuter which reduces the carpet pieces into fractional components. The chilling step could lower the temperature of the soaked carpet pieces to or below freezing to stiffen the backing material and enhance the comminution process. Processes for the recovery of the separated fractional components include collecting the components from the respective discharges from the cyclonic comminuter, washing, and separating by carding, static charges, pressure gradients and the like. This effective process will allow for greater utilization of carpet recycling operations to prevent used carpet from being disposed in land fills.

Method and apparatus for separating and recovering fractional components

A round baler for forming round bales of crop material includes side-by-side belts trained for movement between a starting position and a finish position around a series of stationary rollers including a forward baler roller and a rear baler roller spaced apart from the forward baler roller. Upper and lower roller arrangements are continuously engageable with the crop material. The upper roller arrangement, the lower roller arrangement and a run of the belts extending between the forward baler roller and the rear baler roller together define a starting baler chamber. A belt tracking and tensioning device is interposed between the forward baler roller and the rear baler roller. The belt tracking and tensioning device is mounted on the upper roller arrangement, and functions to maintain the belts in a predetermined relationship relative to the upper roller arrangement and to increase the tension of the belts in response to bale growth, as the belts move between the starting position and the finish position.

A method of removing fractional components from earthen material, including processes for removing precious carbon jewels from soil, precious metals from low grade ores, lead pellets from contaminated soil, and free sulphur from coal, is initiated with a pulverizing of the earthen material bearing the fractional component to be removed therefrom. Subsequent process steps vary, but include the washing of the pulverized material and then removing the fractional component through electromagnetic extraction, chemical dissolution and sieving. Since no contaminate is added to the residue remaining after removal of the fractional component, the residue can be returned to the ground from which the original material was obtained without effecting any additional pollution to the ground or water.

Method and apparatus for recovering fractional components of soil

An apparatus and method for removing hydrocarbons from soil is disclosed. A gradient force machine pulverizes contaminated soils, which are then mixed with release agents in a mixing tank. A water-filled separation unit receives the mixed soil, the unit having a plurality of counter-rotating augers to aid in the breakdown of the mixed soil to solid, water and hydrocarbon components. A washing container receives the solid component from the separation unit, the container having a diagonally-disposed, enclosed auger for outputting a washed solid component. Hydrocarbons that have floated to the top of the separation unit and washing container are removed by a vacuum system.

Soil washing apparatus and method

A system for removing oil from oil/water or oil/sand or oil/water/sand mixtures. An oil/water mixture is taken from an oil spill on the surface of the water or from other sources such as producing oil wells and is transported to a surge tank where it is agitated and then passed on to a separator which separates the oil from the water. The system also covers separating oil from sand or earth when the spill is on land.
