Patent number: 7034198Abstract: A conventional method of pyrolytically decomposing plastic to make low-molecular compounds is poor in efficiency of use of energy due to high heating temperatures (at least 600° C. and 800° C. at maximum). The invention provides that a functional powder is heated to a predetermined temperature and pieces of plastic to be disposed are caused to be contacted with the heated powder, the functional powder including a powder which does in an aqueous solution state show alkalinity, and a photo-catalyst effect powder.Type: GrantFiled: March 27, 2002Date of Patent: April 25, 2006Assignee: Osada Giken Co., Ltd.Inventors: Hideharu Osada, Tatsutoshi Shimabara

Patent number: 6984769Abstract: A reactive coating composition and method for treating a surface including heavy metals by applying the reactive coating composition to the surface. The surface can be, for example, a paint layer containing heavy metals. The reactive coating composition includes a stabilizing agent to stabilize the heavy metal and a permeability enhancing agent to increase the permeability of the paint layer, facilitating the reaction of the heavy metal with the stabilizing agent. The structure including the treated paint layer can be left in place or can be disposed in a non-hazardous landfill.Type: GrantFiled: April 3, 2003Date of Patent: January 10, 2006Assignee: MT2, LLCInventors: James Barthel, Mark A.
