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 process for reforming the fly ash by heating a raw fly ash powder that contains the unburned carbon and thereby decreasing the content of the unburned carbon, characterized in that (a) as means for heating the raw fly ash powder, use is made of a heating unit that heats the raw fly ash powder by passing it through a heated medium-fluidized bed, (b) a high-temperature gas stream is passed through the heating unit to form the heated medium-fluidized bed and to fluidize and convey the raw fly ash powder that is thrown into the medium-fluidized bed, (c) the flow rate of the high-temperature gas stream is so set that the raw fly ash powder thrown into the heating unit is all heated in the medium-fluidized bed and is taken out from a take-out port provided at an upper part of the heating unit but that the particulate medium forming the medium-fluidized bed is not discharged from the take-out port, (d) the fly ash powder after heated and discharged from the take-out port of the heating unit is introduced into an air classifier where it is separated into a fine powder and a coarse powder, (e) the fine powder separated by the air classifier is recovered as the reformed fly ash, and (f) the coarse powder separated by the air classifier is measured for its content of the unburned carbon and when the measured value is larger than a predetermined threshold value, the coarse powder is introduced again into the heating unit so as to be heated again and when the measured value is smaller than the threshold value, the powder is recovered as the reformed fly ash.

The present application overcomes the disadvantages of the prior art by providing a system for proper life-cycle management of plastic products and the plastic waste that plastic products produce.

The present invention relates to a porcelain stoneware element for the construction of driveways.

Treatment technology directed to using mine waste as a raw material to manufacture a mine filling product for use as a suitable precursor product or mine filling product to be used as a backfill material to close a mine. The precursor product or mine filling product retains its metals and is not be able to generate acidity. According to the disclosure, the precursor product or mine filling product, when placed in a mine, may also remove metals from mine fluids in the mine it contacts, and still retain the metals it hosted when it was a mine waste prior to it being used as a raw material to manufacture the precursor stowing backfill product.

The present disclosure provides efficient and cost-effective methods for producing synthetic soil and synthetic stone from waste, including inorganic waste and organic waste, through a hydrolysis-polycondensation process.

The summary of the utility model describes a light mineral organic insulation product that is characterized by the modification of elements found in nature and the environment which, through the process described above, lead us to obtain this insulation which Due to its characteristics and composition of the elements described and its great advantages in the use of resources that are polluting to the environment, it will generate a great impact in the construction industry because, among other advantages, costs are considerably reduced, as well as the times of installation which will optimize human resources saving man-hours because its installation is extremely simple and the materials are light and manageable.

This isolation aims to strongly promote a new generation of less aggressive proposals for the planet that will have repercussions for the benefit of future generations.

Method and apparatus 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 through which a piston circulates inside an extrusion cavity, which comprises three sections and is fed with a parget obtained after pre-processing the waste. The end of the third section is connected to the reactor through an opening. The reactors longitudinal shaft is formed by a rotatory steel shaft in which some steel blades are arranged, 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 to discharge the parget present in the boundary area through some openings, once it has been processed by a series of pressure, vibration energy and decompression cycles.

A cement composition based on a sulfoaluminate clinker is described, together with its use for agglomerating and inerting sediment/dredging sludge, and the relative inerting method and apparatus.

An on-site heavy metal contaminated soil treatment apparatus, comprising a sampling system, a molding system, a heat processing system and a tail gas processing system disposed in sequence. The sampling system includes a bucket elevator and a planetary stirring device which are connected in sequence and are disposed on a mobile platform of the sampling system. The apparatus is easy to move and assemble, has a small floor area, and can be built on a target contaminated site, reducing transportation costs and the risk of secondary contamination. The entire process performed by the apparatus proceeds automatically, reducing labor costs. The planetary stirring sampling method and automatic brick blank extrusion molding process of the apparatus are applicable to various types of heavy metal contaminated soil providing high processing efficiency and good molding effect. Combined microwave heating and high-temperature steam heating provide rapid heating, small thermal inertia, and easy temperature control.
