  • Patent number: 7670277
    Abstract: A method of solidifying toxic or hazardous liquid waste, including the steps of pumping an aqueous waste, e.g., from a drilling fluid holding area; through a shearing device; adding the layered phyllosilicate to said aqueous waste in an amount sufficient to solidify the aqueous waste sufficiently such that the solidified aqueous waste has no free liquid; shearing the pumped aqueous waste, containing said layered phyllosilicate, sufficiently to partially exfoliate the layered phyllosilicate into phyllosilicate platelets and tactoids while in contact with the aqueous waste; pumping the sheared aqueous waste and layered phyllosilicate to a solidification area; and allowing the sheared aqueous waste and partially exfoliated layered phyllosilicate sufficient time to solidify such that there are no free liquids remaining in the solidified waste.

  • Patent number: 7670082
    Abstract: Reactive gabion/geocomposite articles, and their methods of manufacture, for controlling contaminants in soil, sediment or water that allow the passage of essentially non-contaminated water therethrough. The articles and methods described herein utilize gabions, which are box shaped cages or grids (see FIG. 2) made of either steel wire mesh or plastic. In one embodiment, the reactive geotextile mats are lined on the top major surface with a gabion cage or grid. In other embodiments, the cages or grids surround a geocomposite containing reactive material. The gabion/geocomposite articles can be constructed in-situ (at the site of deployment) or remotely (on land or barge) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion/geocomposite articles may be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring.

  • Publication number: 20090292055
    Abstract: A nanocomposite is made from melt-mixing of polyethylene with organoclay in the presence of a maleated polypropylene. Unexpectedly, the maleated polypropylene and polyethylene are sufficiently compatible to permit excellent dispersion of the organoclay in the nanocomposite. Because maleated polypropylene is compliant with U.S. Food and Drug Administration regulations, though maleated polyethylene is not, one can use nanocomposites of the present invention for articles to be in contact with human food.

  • Patent number: 7619024
    Abstract: A resin composition comprising melt blending a polyamide resin such as nylon MXD6 with a polyphenoxy resin. The polyamide resin and the polyphenoxy resin may be combined prior to or after melting and can be sandwiched between two PET layers in a perform mold to form an article capable of blow molding to form a container with improved delamination resistance. Also, intercalated layered materials are prepared by co-intercalation of an onium ion, an aromatic polyamide oligomer or polymer, e.g., nylon MXD6, and a polyphenoxy oligomer or polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The co-intercalated layered materials are combined with the aromatic polyamide and polyphenoxy resin to form a nanocomposite composition for sandwiching between PET layers to form containers having improved delamination resistance.
