[CO.sub.2] Cleaning Technology Recycles Oil Bottles.Honeywell Federal Manufacturing & Technologies in Kansas City Kansas City, two adjacent cities of the same name, one (1990 pop. 149,767), seat of Wyandotte co., NE Kansas (inc. 1859), the other (1990 pop. 435,146), Clay, Jackson, and Platte counties, NW Mo. (inc. 1850). , Mo., has patented a method using [CO.sub.2] to clean residual motor oil from HDPE HDPE abbr. high-density polyethylene bottles, so that both can be recovered in a highly pure state. Unlike previous attempts using solvents or water, Honeywell's new approach reportedly produces no environmentally hazardous Environmentally hazardous is a chemical hazard, where significant damage to the environment is caused by a chemical substance.

[CO.sub.2] acts like a solvent to wash away the oil, is similar to the method of decaffeinating coffee. Honeywell has licensed the technology to ITec International Technologies, Inc. of Cincinnati, which plans to sell [CO.sub.2] cleaning equipment for oil bottles. ITec plans to commercialize its "[ECO E·co , Umberto Born 1932. Italian writer best known for his novels, including The Name of the Rose (1981).

According to Honeywell, at least 2 billion one-quart motor-oil containers are discarded annually in the U.S., mostly to landfills. These containers (about 250 million lb of HDPE) contain nearly 15 million gallons of oil. HDPE cleaned with [CO.sub.2] reportedly can be used in high-value applications like packaging, pallets, and tote boxes. |
