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.

A method for providing long term carbon sequestration and reducing an individual's personal carbon footprint comprises: growing, harvesting, drying and grinding a plurality of weeds, then pressing the ground weeds into hollow block shells for manufacturing blocks therefrom. The hollow block shells could be made a recycled plastic, a plant based plastic, bamboo, a reclaimed wood fiber, ground up nut shells and/or a fungus material. The method, and the blocks manufactured thereby could conceivably impact total atmospheric carbon dioxide levels as a CO.sub.2 Net Negative Emissions (NNE) technology.

A solution comprising at least one protic solvent, at least one monomer comprising an (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide group, at least one crosslinking agent comprising at least two groups chosen from (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide groups, at least one photopolymerization initiator and at least one agent chosen from alkali metal halides, alkali metal phosphates, alkali metal sulfates and mixtures thereof; or—of a polymer material capable of being obtained by polymerization of the solution defined above comprising a polymer resulting from the polymerization of the monomer(s) and of the crosslinking agent(s) as defined above and trapping, at the center thereof, a liquid phase comprising at least one agent as defined above; for the trapping of at least one toxic chemical agent.

A waste material improvement and reuse method involves identifying an available material having a crush resistance that does not meet a requirement for use as proppant, but which can be improved to meet the requirement, and modifying a surface of the available material to improve the crush resistance to meet the requirement by applying a binding agent and/or an encapsulating agent to the available material, forming clumps of particles of the available material and increasing crush resistance.

Fossil-fuel and rubber-derived waste stream conversion to composite lumber substitutes or barrier members; the composites having material properties and uses of greater value than the solid waste stream components separately or together. Preferred combinations including waste materials derived from waste carpet, waste tires, and waste bituminous roofing shingles, all enormous problems for landfill disposal. In a range of formulation ratios, when combined with a binder, new and marketable products are made from solid waste. Improved resistance to rot, to water, and to weathering is exhibited in synergy with improved compressive and flexural strength, enabling production of a wide variety of useful and environmentally-friendly structural products, for example. Product weight and strength can be engineered to suit and may be structural members for architectural, engineering or agricultural use. Advantageously, the new products themselves can be re-usedby an end-of-life process for making more new products, achieving the capacity to make and remake multigenerational products from solid wastes and to reduce loading of landfills.

Methods for the treatment of metallic particles such as heavy metal particles and objects contaminated with the metallic particles. For the treatment of objects contaminated with the metallic particles, a stabilizing composition may be applied to the object with or without a fixation agent. For the treatment of free-flowing metallic particles, an agglomeration agent may be used with or without a stabilizing agent.

A method of processing municipal solid waste includes extracting food waste, inert materials, and ferrous and non-ferrous metals from the municipal solid waste, shredding the municipal solid waste and thereby generating a product feed comprising at least 99.7% by volume cellulose-based materials and plastic. The product feed is conveyed to a forming system and a manufacturing product is created out of the product feed with the forming system.

The present disclosure describes a unique, two-part, water-soluble polymer matrix material and a method of application that immobilizes a wide variety of loose powder or crystalline hazardous materials and renders them safe or at least safer for handling and transport. The polymer matrix material is a two-part polymer material comprising a liquid cross-linking polymer and a cross-linking agent, initiator, or biocide contained in a solution. The cross-linking agent functions to cross-link the polymer and cause it to harden in place.

A kitchen garbage treatment material absorbs moisture contained in kitchen garbage, and is constituted by grains. The grains contain a water-absorbent material. The water-absorbent material is constituted by at least one of fluff pulp and water-absorbent polymer that have been obtained by separating plastic from a sanitary product that contains the plastic, the fluff pulp, and the water-absorbent polymer.
