Described herein are compositions and methods for waste-to-energy ash in engineered aggregate in road construction.

A method of valuation of raw fines materials, comprising selectively screening, biotreatment or composting of raw fines materials or selection as fillers in composites. The method comprises screening the raw fines materials to Grade 1 comprising fines materials of a size of at most about 5 mm and Grade 2 comprising fines materials of a size larger than about 5 mm; and at least one of: A) bio-oxydating organic contaminants of the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions and monitoring a content of organic contaminants until the content of organic contaminants stops decreasing; and B) composting the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions, and monitoring pathogens content and respiration rate; and stopping the addition of organic amendment upon detection of absence of pathogens at a predetermined respiration rate.

The present invention provides compositions and methods for converting hazardous waste glass into safe and usable material. In particular, the present invention provides compositions and methods for producing ceramic products from toxic-metal-containing waste glass, thereby safely encapsulating the metals and other hazardous components within the ceramic products.

The invention relates to a system for neutralizing asbestos, said system comprising a mobile neutralization unit (200) comprising: an asbestos waste sorting module (225), an asbestos grinder (255) and a hot acid bath (250) for rendering asbestos inert.

Preferably, the asbestos waste sorting module comprises: a window with glove boxes; and a conveyor for transporting the asbestos waste in front of the window.

In embodiments, the system comprises a means for containing the atmosphere within the mobile neutralization unit and/or the hot acid bath (250) of the mobile neutralization unit (200) comprises sulfuric acid.

Extended-life cement compositions are provided and, more particularly, extended-life cement compositions are provided that comprise a cementitious component comprising red mud solids and hydraulic cement. A method of cementing may comprise providing an extended-life cement composition comprising a cementitious component, water, and a cement set retarder, wherein the cementitious component comprises red mud solids and a hydraulic cement; activating the extended-life cement composition; introducing the extended-life cement composition into a subterranean formation; and allowing the extended-life cement composition to set in the subterranean formation.

The invention relates to a method and furnace allowing the use of filter earth (diatomaceous earth) waste, in which the organic material is removed using the method of the application. The furnace comprises a container in which the industrial waste is deposited, and a folding table is used to transport the material. The invention also includes an agitator with a base, used to lower blades and remove the treated material. The gases generated are collected by an extractor which includes a cooling jacket and are subsequently sent to an absorber system in which they are neutralized. Said device and method are used to obtain lightweight materials with low porosity and high compression strength, rendering solid granular industrial waste that is dangerous to the environment suitable for use in the construction or mechanical industries.
