    Abstract: 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 crosslinking or both polymerization and crosslinking 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.

    Abstract: 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.

    Abstract: An assembly and method for processing human waste includes providing a supporting base having an opening within which a waste reservoir is affixed. The assembly may be installed on or below a rim of a toilet bowl. Solidification and pathogen killing materials are provided. The materials are deposited in the reservoir either prior to or upon accumulation of waste in the reservoir. The reservoir with the solidified waste is then sealed and transported to a collection facility.
