Describes technologies used to conserve energy by using process wastes in the following situations: (1) incineration at a photographic company, (2) wet oxidation at a paper mill, and (3) sewage skimmings fuel at a municipal waste water plant. (MA)

An attempt to determine the reasons for substandard wastewater treatment plant performance is made. Recommendations include a change in existing operator training methods. (MR)

Discusses problems relating to an international solution to the disposal of high-level radioactive waste problem. (SL)

A primary responsibility of field environmental health workers is evaluation of individual sewage disposal system sites. The authors of this article developed a practical, accurate, and inexpensive measurement device for obtaining reliable percolation test results. Directions for the construction and use of the device are detailed. Drawings…

For more than a decade, the Chinese have been using biogas digesters to produce fuel for homes in rural areas. This article discusses the design, operation, and benefits of these digesters. This means of waste treatment helps improve sanitation, produce fertilizer, and save fossil fuels. (MA)

Transmission electron microscopy and scanning electron microscopy are used to detect asbestos by analyzing filters from air tests. The modes of operation and types of samples examined by each are explained. Circumstances that a school board should consider when deciding whether to use these methods are discussed. (MLF)

This report focuses on the prospects and possibilities for using biomass as an energy source for the United States. However, the greatest potential for utilizing biomass as fuel exists in energy-starved developing nations, since it appears possible to develop biomass technologies keeping capital inputs low in relation to labor inputs. (BT)

With increasing environmental problems, there is a large social demand for environmental policy. Education is a powerful source to fulfill this demand and the Foundation for Environmental Education in Europe's (FEEE's) Eco School program aims to develop awareness of environmental issues and sustainability among elementary and secondary school…

Describes methods of utilizing kitchen garbage for teaching science, math, social studies, geography, art, and language. (JA)

Headquartered at Joliet, Illinois, the Army Ammunition Procurement and Supply Agency aims to mechanize and clean up its manufacturing facilities. Six go-co (government owned - contractor operated) plants involved in the modernization program are described. (BL)

To aid in personnel training and as a complement to its enforcement program, the Minnesota Pollution Control Agency implemented an operator assistance program in June 1976. Its principle objective was to train operators in process control to improve their skills and enhance their long-term ability to produce high quality effluent. (Author/JN)

The water shortage problem can only be met by creating a linkage among water supply, sewage disposal, and storm-water control. At present, these basic components of water management are typically handled separately, as if water were an unlimited resource the use of which does not require much foresight. (RM)

Discusses theorectical and methodological challenges presented to the social science community by large-scale radioactive waste management. Overviews analysis, management, and decision making. (MK)

Encapsulation has proven to be the safest, surest, and most permanent method of treating sprayed asbestos on ceilings and walls. Federal aid is available to help pay for inspection of school buildings for asbestos and for asbestos removal. (Author/MLF)
