MITI is currently undergoing research to develop technology for the recycling of non-flammable plastics such as those used in business machines and computers. Their National Institute for Resources and Environment plans to decompose, without the production of harmful substances, non-flammable polymers by means of liquid phase hydrocracking, and to recover from them light oils such as benzene, toluene and xylene. The key to the technology, it is claimed, lies in the development of a catalyst which will be able to combine hazardous substances such as bromine and chlorine contained in the waste plastics. 

A serious drawback is the large amount of CAN (up to 2.5 molar amounts) needed. Cerium salts are highly toxic pollutants and must be removed from industrial effluents and wastewaters. Cerium (III) solutions from penem pilot plant solutions containing up to 1.2 M Ce(III) were recycled in a two compartment Electro Syn Cell. Typical recycling conditions Nation diaphragm with coated Ti-anode, applied current densities = 50-150 A/em2 yield > 90% processed amount about 475 kg CAN [46,126,136,137], The simultaneous determination of Ce(III) and Ce(IV) in the pilot plant solution and in solid CAN can be performed polarographically. As little as 0.3% Ce(NH4)2(N03)5 can be determined in Ce(NH4)2(N03)6 [136]. 

Several pollution control technologies at the refinery promote cross-media transport, the transfer of pollutants from one medium to another. Wastewater, for example, may contain hydrocarbons that volatilize into the air at the refinery, the wastewater treatment plant converted these waterborne hydrocarbons into 2400 tons/year of sludge, which were recycled to the coker. Cross-media transport from air to water is not significant for hydrocarbons or chemical that are only slightly soluble in water (Allen et al, 1989). Studies performed by the National Center for Intermedia Transport at the University of California, Los Angeles, for instance, showed that most hydrocarbons released into the air do not transfer rapidly into other media. Therefore, ignoring intermedia transfer when examining air quality impacts is a reasonable analytical approach. Water-soluble compounds, such as methanol and MTBE, can transfer from air into water and soil media under certain conditions (Cohen et al., 1991). 

Prior to leaving the manufacturing plant, all lead-add batteries should be labelled (Fig. 16.3) in accordance with prevailing national and international [8] regulations and with the international recycling symbol ISO 7000 1135, better known as the Moebius loop. Furthermore, there should be instructions for the recycling of the battery or a point of contact clearly displayed when it is at the end of its useful life. Each label should state, lead-acid battery , Pb or the words LEAD , RETURN and RECYCLE . If possible, the label should also have a bar code which contains information about the place of manufacture, the date of production, the battery type, and its components.
