Regional and supraregional treatment centers have been developed in Switzerland to cope with the problem of systematic toxic waste disposal. The process employed at the Fairtec Turgi plant is described beginning with delivery and storage and proceeding through treatment, reprecipitation, decontaminating cyanide, filtering sludge and ion-exchanger…

Implementation of the recommendations of the National Commission on Materials Policy is happening, but at a slow pace. Resource recovery has gained strong implementation action within government and private industry, but to insure success, certain policy objectives related to supply and demand of materials and materials management must be carried…

Advances in research and commercial solid waste handling are offering many more processing choices. This survey discusses techniques of storage and removal, fragmentation and sorting, bulk reduction, conversion, reclamation, mining and mineral processing, and disposal. (BL)

Most waste treatment techniques conceived to meet the 1977 standards can be separated into three distinct phases: primary, secondary and tertiary treatment. An examination of the four heaviest industrial water users, pulp and paper, steel, plating, and food processing, demonstrates these treatments use proven technology to meet specific…

Industry is faced with handling, disposing and recovering vast amounts of waste, much of it as a result of present pollution control technology. Industry has found the technology available, expensive and, without regulation, easy to ignore. Many industries are therefore improperly managing their wastes. (BT)

Modern thermal solid waste processing systems are becoming more complex, incorporating features that require instrumentation and control systems to a degree greater than that previously required just for proper combustion control. With the advent of complex, sophisticated, thermal processing systems, TV monitoring and computer control should…

Discussed in this article are the various processes (Poz-O-Tec, Calcilox, R-C, Chemfix) now in use by several companies to process scrubber sludge so that it can go to making aggregate, to landfills, or to other uses, depending upon economic conditions in the vicinity of an SOx scrubber. (BT)
