A method of recycling tires places tires and/or pieces of tires within a casing or mold. A binder (e.g. adhesives and/or pining with screws, nails, nuts and bolts, pins, wire and steel or nylon bands etc) is applied to the tires and/or pieces of tires so that the tires are bound together. A reinforcing means is applied to the tires and/or pieces of tires (e.g. fitting the reinforcing means around, in between and/or through the tires etc). An encapsulating means is melted and poured over the top of the tires and reinforcing means to encapsulate them inside the casing or mold and the encapsulating means. The encapsulating means is allowed to set such that a recycled product is formed.

Methods and an associated system for processing unhardened concrete are disclosed. With these methods, the porosity of the unhardened concrete is significantly increased to decrease the strength so much that it can be easily broken up for sale or reuse. In at least one embodiment, the method includes adding a large volume of foam to the returned unhardened concrete and then mixing the foam with the returned concrete in the ready-mix concrete truck or other concrete mixing devices at any location including the jobsite, enroute to the concrete plant, or at the concrete plant. Through the mixing of foam with the returned concrete, the hydrated cement and aggregate particles are separated by large volumes of air voids, which significantly increase the porosity and dramatically reduce the strength of the returned concrete. The treated concrete is discharged and allowed to solidify in this weakened state, after which it is easily broken into loose particulate material that can be sold or reused.

A method for preparing composites of polymer and fly ash particles, wherein the fly ash particles contains heterogeneous compositions of carbon and metal oxides, the method including: the steps of mixing the fly ash particles and an aqueous coating solution, including: a coating component selected from the group consisting of monomers, oligomers, pre-polymers, polymers, and combinations thereof, and an aqueous solvent serving to dissolve the coating component; and, while performing the step of mixing, initiating polymerization or cross linking or both polymerization and cross linking of the coating component to at least partially coat the fly ash particles with polymer or a crosslinked polymer network that agglomerates the fly ash particles and coats the surface of the fly ash particles, wherein the polymer or crosslinked polymer network formed in the step of initiating is hydrophobic.

A cover material for a bulk material pile and method for applying the cover material are disclosed. The cover composition is free of fiber, clay, cement and pozzolanic material and comprises: 95 to 99.75 percent by weight water, 0.25 to 5 percent by weight of a water dispersible cellulosic polymer; and sufficient acid to maintain the pH of the solution between 1.0 and 6.0. The method for applying the cover material includes: providing the cover composition, which contains 95 to 99.75 percent by weight water, 0.25 to 5 percent by weight of a water dispersible cellulosic polymer; and sufficient acid to maintain the pH of the solution between 1.0 and 6.0; applying the cover composition onto a bulk material pile; and allowing the composition to harden to provide a cover to at least a portion of the bulk material pile.

A composition and method for spray-applying a two-part, self-setting composition containing a dopant that provides a hazard shielding component and is particularly adapted for delivering the components of the composition at a temperature that promotes their spray application as well as a self-setting reaction. The method includes selecting a self-setting compound that is adapted for curing in place once applied, the self-setting compound including at least one dopant material; and applying the compound to a hazard to be encapsulated such as a radiological, lead, asbestos, or PCB. Alternately, a self-curing compound includes a multi-part compound which, upon a mixing of the parts, chemically reacts and cures, and at least one dopant material dispersed into at least one of the parts, wherein the dopant material is selected for providing radiation shielding upon application of the compound.
