Berry, R. Stephen – Bulletin of the Atomic Scientists, 1971
Suggests formula for survival that takes a thermodynamic view which holds that we must recycle waste while the thermodynamic potential still is moderately high. Otherwise they are lost, as helium is lost when it leaves Earth's atmosphere and goes into space. The idea that the Earth is a closed system is a myth; it collapses each time we put our…

Postel, Sandra – 1985
This report addresses the global concern of water development and stresses the need for management of the water demand. Investments in water efficiency, recycling, and conservation are recommended over conventional water supply projects for greater cost behefits and production yield. Topic areas include: (1) water use trends in major crop…

Berry, R. Stephen; Fels, Margaret F. – Bulletin of the Atomic Scientists, 1973
Presents two respective comparisons between ideal and real energy cost for the manufacture of a new automobile and between free energy savings from processing the old automobile into low and high grade scraps. Suggests the wasted thermodynamic potential should be considered in making decisions about energy savings. (CC)

Environmental Science and Technology, 1975
While all seem to agree that recycling will alleviate solid waste problems and energy and mineral shortages, recycling is, at present, bogged down by the thin market for recycled materials, the recessionary business picture, the vertical integration of many companies, unfavorable tax laws, and high rail freight rates.

Tillman, David A. – Environmental Science and Technology, 1975
Three systems, operating at sufficient scale, produce fuels that may be alternatives to oil and gas. These three recycling systems are: Black Clawson Fiberclaim, Franklin, Ohio; Union Carbide, South Charleston, West Virginia; and Union Electric, St. Louis, Missouri. These produce a wet fuel, a pyrolytic gas, and a dry fuel, respectively. (BT)

Schulz, Helmut W. – Environmental Science and Technology, 1975
Municipalities and industry are being forced to seek alternatives to sanitary landfills and incineration as means of eliminating solid wastes. Based on the Columbia study, the two most cost-effective, environmentally acceptable alternatives are the high temperature, oxygen-fed pyrolysis process and the co-combustion of refuse-derived fuel in…

Carroll, Katherine – 1973
This guide explains what is involved in recycling paper. Some background history is presented on the use of recycled paper. Sources of use for this product are pointed out, especially instances where business and industry have found that recycled paper could be used in place of the virgin product. The major part of the guide consists of samples of…

Goeller, H. E.; Weinberg, Alvin M. – Science, 1976
Dwindling mineral resources might cause a shift from nonrenewable resources to renewable resources and inexhaustible elements such as iron and aluminum. Alternative energy sources such as breeder, fusion, solar, and geothermal power must be developed for production and recycling of materials. Substitution and, hence, living standards ultimately…
