Wisconsin has a law that requires that all plastic containers consist of at least 10% recycled or remanufactured material. Food, beverages, and drugs are exempt if FDA has not approved the use of the specific recycled or remanufactured content in that plastic container. An exemption for cosmetics containers was added by amendment. Because use of post-industrial material is counted towards the 10%, it appears that the law has not had any significant effect on packaging decisions. 

The Crandon massive sulphide deposit is found in Precambrian volcanic rocks of the Rhinelander-Ladysmith greenstone belt, which trends east-west across the northern part of Wisconsin. Mineralisation occurs in a sequence of volcanic and associated sedimentary rocks which strike about N85 W, dip 70-90 Tl, and consists of laminae of sphalerite in pyrite with minor amounts of galena and chalcopyrite. Stringer sulphide mineralisation underlies the massive sulphide ore and consists of quartz-chalcopyrite-pyrite and pyrite-chalcopyrite-sphalerite veins. The deposit is covered by up to 65 m of glacial drift. 

From the range of gases determined at Crandon it was evident that the concealed massive sulphide deposit is indicated by positive CO2 anomalies coincident with negative O2 anomalies. However, the sulphur gases H2S, COS, CS2 and SO2 were found to be absent.

The Novosibirsk Institute of Organic Chemistry has developed a method for computer-aided retrieval of stmctural information from H-nmr using its database of 50,000 spectra (72). Eraser WUHams Ltd. (Scientific Systems) has special software to search its E-nmr database (73). Protein nmr data have been compiled into a relational database at the University of Wisconsin (74). 

The largest cost to produce malt is the cost of barley. U.S. barley and malt prices from 1966 through 1992 are shown in Eigure 8, along with the spread between malt and barley prices. The spread or margin between malt and barley prices is expressed in /t of malt and assumes 5% of barley purchased is cleanout barley and that 92% of barley soHds ends up as malt. Barley and malt prices are pubHshed in The Brenners Bulletin (Thiensville, Wisconsin). 

Only two companies produce specialty malts in roasters or specialty kilns in North America Breiss Malting Co. (Chilton, Wisconsin) and Extractos y Maltas (Mexico City). Other malting companies produce high dried malts in conventional kilns which are used by brewers for color or flavor purposes. Specialty malts represent less than 2% of malt sold in North America. 

The leading states in milk production in decreasing order are Wisconsin, Minnesota, New York, California, and Pennsylvania. These states produce - 45% of the U.S. milk supply. Less than 5% of the total production is used on farms and the remainder is sold for commercial purposes. Whereas milk and cream were formerly shipped in 19-, 30-, or 38-L cans from the farm to the plant, in the 1990s most commercial production, particularly for fluid milk, is moved in bulk from the cows to refrigerated farm tanks to insulated bulk tmck tankers and to the manufacturing plant. The investment in equipment and the cost of hired labor are associated with large, capital-intensive production centers. 

The low (ca 2%) yield of NO, the tendency to revert to N2 and O2 if the product stream is not quenched rapidly, the consumption of large (ca 60,000 kWh/1N2 fixed) amounts of electricity, and the concomitant expense to sustain the arc all led to the demise of this process. The related Wisconsin process for oxidising N2 at high temperatures in a pebble-bed furnace was developed in the 1950s (13). Although a plant that produced over 40 t/d of nitric acid was built, the product recovery costs were not economically competitive.

The first centralized electric generating plant in the United States was Edison s three-unit steam-engine-based station, which suppHed electric power to light approximately 5000 electric lamps in a group of homes and businesses in New York City in 1882. Also in 1882, the first hydroelectric power plant went into operation in Appleton, Wisconsin, generating approximately 25 kW of power, enough to power more than 200 100-watt light bulbs. 

Kutrieb Corporation (Chetek, Wisconsin) operates a pyrolator process for converting tires into oil, pyrolytic filler, gas, and steel. Nu-Tech (Bensenvike, Illinois) employs the Pyro-Matic resource recovery system for tire pyrolysis, which consists of a shredding operation, storage hopper, char-coUection chambers, furnace box with a 61-cm reactor chamber, material-feed conveyor, control-feed inlet, and oil collection system. It is rated to produce 272.5 L oil and 363 kg carbon black from 907 kg of shredded tires. TecSon Corporation (Janesville, Wisconsin) has a Pyro-Mass recovery system that pyroly2es chopped tire particles into char, oil, and gas. The system can process up to 1000 kg/h and produce 1.25 MW/h (16). 

Small tire chips have also been utilized as a soil amendment to improve athletic playing fields (see Recreational surfaces). A patented process marketed under the trade name Rebound (fai Tire) combines cmmb mbber from scrap tires with composted organic material to reduce soil compaction, resulting in better athletic playing surfaces (52). Installations have been made in Florida, California, Colorado, Hawaii, Maryland, Michigan, Missouri, Nevada, Virginia, and Wisconsin. 

Several utihties are burning or have successfully test-burned I DE. Eor example, the results of a pilot project at Wisconsin Power Light (WP L) were so successful that the utihty installed its own system to shred tires, thereby assuring a steady supply of uniformly sized tire chips. The tire processing plant will enable the utihty to manage about 20% of the 5 x 10 waste tires generated each year in Wisconsin.
