Method and apparatus (100) for transforming organic and inorganic solid urban waste into aggregates, comprising an extruding machine connected to a reactor. The extruding machine is formed by an extrusion cylinder (103) through which a piston circulates (104) inside an extrusion cavity (106), which comprises three sections (107, 110, 111) and is fed with a parget obtained after pre-processing the waste. The end (115) of the third section (111) is connected to the reactor (112) through an opening (114). The reactor's longitudinal shaft is formed by a rotatory steel shaft (116) in which some steel blades are arranged (108), whose ends play the roles of cutting, hammering, punching and hydraulic helix as they rotate. Between the end of the blades and the wall of the reactor, there is a clearance of more than 0.1 mm of thickness. The reactor has a discharge valve (300) to discharge the parget present in the boundary area through some openings (304), once it has been processed by a series of pressure, vibration energy and decompression cycles.

A method for vitrification of arsenic and antimony, comprising substituting oxygen to sulfur on thiosalts, incorporating resulting sodium arsenate and sodium antimonate into a sodium silicate glass-forming mixture and vitrifying the sodium silicate glass-forming mixture into a resulting glass sequestering the arsenic and antimony.

Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste, human waste, or another bio-solid.

Systems and methods of the present invention include a method for the treatment of drilling wastes and coal combustion residues, comprising combining at least a first drilling waste with coal combustion residues to form a paste, combining at least a second drilling waste with coal combustion residues to form a compactable fill, and placing the paste and the compactable fill in a landfill. Other embodiments include a method of treating drilling wastes and coal combustion residues, comprising combining at least one drilling waste with a coal combustion residue to form a paste. Further embodiments include containing the paste within at least one geotextile container. Still further embodiments include placing the geotextile container in a landfill.

A method of processing cathode ray tube (CRT) glass with waste glass into a pozzolanic mixture includes, receiving CRT glass aggregate, pulverizing the CRT glass aggregate forming an intermediate CRT glass product, fine grinding the intermediate CRT glass product into a powder, receiving waste glass, pulverizing the waste glass forming an intermediate waste glass product, fine grinding the intermediate waste glass product into a waste glass powder, and combining the waste glass powder with the CRT glass powder by weight or volume to form the pozzolanic mixture. The pozzolanic mixture may be used in place of Portland cement in a cementitious mixture. Also, a leaded portion of the CRT glass may be used in the cementitious mixture to act as a radiation barrier.

A method of distributing ashes by forming water soluble solid product(s) with the ashes. Upon wetting the water soluble product(s), the binder releases in a period of about time thereby allowing the ashes to dissipate into nature while minimizing the likelihood of having airborne ash.

Methods for the treatment of metallic particles such as heavy metal particles and objects contaminated with the metallic particles. For the treatment of objects contaminated with the metallic particles, a stabilizing composition may be applied to the object with or without a fixation agent. For the treatment of free-flowing metallic particles, an agglomeration agent may be used with or without a stabilizing agent.
