A granulated formulation formed from ETA (Water Treatment Plant) sludge and minerals from magmatic and/or sedimentary and/or metamorphic rocks, rich in magnesium and potassium silicates in addition to silicon dioxide and other components, representing an innovation in waste recycling processes for environmental purposes, the replacement of animal substrates by the proposed product and soil nutrient recycling process through generation of organomineral fertilizer resulting from exposure of the substrate to waste from creations in which it is used.

The present application pertains to a process for the decomposition of biomass-material.

A hydraulic binder based on a sulfoaluminate clinker including the mineralogical phases ye'elimite C.sub.4A.sub.3$, mayenite C.sub.12A.sub.7, free lime CaO, and optionally belite C2S, characterized in that, in the clinker, the mineralogical phases are 20% to 50% by weight of ye'elimite C4A3$ phase, 5% to 80% by weight of mayenite C.sub.12A.sub.7 phase, and 1% to 5% by weight of free lime CaO, the weight ratio between the mayenite C.sub.12A.sub.7 and ye'elimite C.sub.4A.sub.3$ phases being between 0.1 and 10. The binder can be used to treat polluted soils, in particular soils with a leachable fraction greater than 0.4% that contains predominantly anions and/or heavy metal cations by mixing the soil with the hydraulic binder, in soil/binder weight proportions of between 1 and 40 parts of binder for 100 parts of soil. It makes it possible to stabilize soils which are polluted or to stabilize soils before dumping.

The present invention relates to a method for treating waste material comprising organic components and low and/or medium level radioactive agents. The method comprises encapsulating the waste material into a matrix, gasifying the waste material at a temperature between 600 and 950° C. to form a gaseous fraction and a solid fraction comprising low and/or medium level radioactive agents and combustion residues of the organic components and encapsulating the solid fraction by a geopolymer matrix comprising metakaolin.

Calcium silicate hydrate nanoparticles are combined with ammonia control materials (e.g. alum, aluminum chloride, ferric chloride, ferric sulfate, and/or sodium bisulfate) to create a phosphorus-binding composition. In the preferred embodiment, the composition is applied to poultry litter, poultry bedding or other non-aqueous substrates that are at least partially comprised of animal manure. The composition binds with phosphorus to at least reduce the amount of phosphorus in runoff water or in leachate from fields fertilized with treated manure. The combining of the calcium silicate hydrate nanoparticles with the ammonia control products has a surprising and unexpected result. The calcium silicate hydrate-ammonia control material mix reduces soluble phosphorus more than either component of the mix alone.

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.

Techniques of forming a foamed insulation material from gypsum waste are disclosed herein. One example technique includes mechanically comminuting the gypsum waste from an original size into particles of gypsum at a target size smaller than the original size and mixing the particles of the gypsum with a binder to form a mixture of particles and binder. The binder is configured to bind the particles of gypsum upon hydration. The example technique can further include performing air entrainment on the mixture until a foam is formed from the mixture having the particles of gypsum and binder. The foam has water that causes the binder to bind the particles of gypsum. The example technique can then include removing moisture from the mixture with the formed foam to form a foamed insulation material from the particles of gypsum.

Disclosed are a zeolite-like material, and a preparation method and use thereof. In the disclosure, cyclic molecules of the zeolite-like material form a closed cage-like cavity structure with each other. The zeolite-like material is synthesized using an inorganic solid waste as a raw material.

The present invention relates to a glass composition. The present invention also relates to a method of forming a glass composition. The present invention also relates to uses of a glass composition.

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.
