Abstract: A method for post-consumer waste segregation, comminution, and creation of a cementitious aggregate, that enables more complete reclamation of zorba from a processing stream segregable from plastic waste. The plastic waste is simultaneously impregnated with silica to create a cementitious aggregate employable with load bearing utility as a substitute for traditional concrete aggregates.

Abstract: A method and apparatus for separating non-biogenic plastic from biogenic waste. A stream of waste materials is delivered through an inlet into a conduit in which the biogenic waste drops out the bottom. The non-biogenic plastic is drawn upwardly by a separator in the form of pressurized gas fed tangentially through two ports in an opposite direction with each other to create a vacuum in the conduit.

Abstract: A method for sequestering carbon contained in waste plastic includes separating the waste plastic from the waste stream prior to incineration, gasification, landfill, or any other method of final disposal of waste, modifying the plastic for use as a modified polymer aggregate, and using the modified polymer aggregate as a constituent ingredient in a durable building material.

Abstract: The present invention comprises an aggregate for use in cementitious building materials which-successfully incorporates plastic such as recycled plastic scrap of diverse types and a abrasive, inorganic grit particles. The plastic scrap is impregnated with a grit, such as sand, glass or other inorganic material. The plastic will then bond satisfactorily with a ark cementitious binder. Impregnation is accomplished by heating the plastic in particulate form, the grit or both, then mixing the plastic and grit. The aggregate can be reinforced by the addition of metallic or artificial fibers. Optionally, the aggregate can be formed with gas filled voids by adding sodium bicarbonate or borax during the heating process or by using plastics which “off-gas” during heating. In a further option, adhesive can be added to the cementitious mix, thereby fusing plastic particles together such that a skeleton providing reinforcement or support is formed in the cured aggregate.
