Productivity and Quality
At one time in industrial America, quality and productivity were considered almost mutually exclusive. Today that is not the case, thanks in part to very different attitudes about the role of workers. American managers today are much less likely to ...
Thermal Treatment Technologies: Thermal Destruction
Since ancient times, the burning of waste has been a common practice. Unfortunately, incineration as generally practiced created serious environmental problems. Today, however, thermal treatment technology has demonstrated its ability to reduce bo...
The Papermaking Industry: Kraft Pulping
In the Kraft process, making pulp begins by conveying wood chips of uniform size into a vessel called a digester. Once the pulp-making process is complete, the pulp is transformed into paper. However, not all mills make both pulp and paper at one ...
The Papermaking Industry: Papermaking and Pollution Control
From pulping, to bleaching, to forming sheets on the paper machine, papermaking creates air emissions, water emissions--or effluent--as well as solid waste. However, the environmental impacts of the process are mitigated by a variety of treatment m...
The Food and Agriculture Industries: The Dairy Industry: Waste Streams and Environmental Management
Environmental management within the dairy industry has changed dramatically in recent years. It's shifted from a reactive to a very pro-active approach, in which the creamery attempts to reduce, reuse and recycle various waste streams, thus minimiz...
The Papermaking Industry: History of Papermaking
A variety of materials and methods is used to create paper, but the basic process still involves techniques that are centuries old: the moistening, separating and intertwining of fibers to form a sheet. Different kinds of fibers are used to make pa...
Biological Treatment Technologies: Biological Treatment, Wastewater and Sewage
Biological treatment is a major application of microbial technology used for treating municipal wastewater and sewage. One of the most important biological treatment processes is anaerobic digestion, in which anaerobic bacteria are placed in huge c...
Water Pollution and Industrial Nations
Explorer and environmentalist Jean-Michel Cousteau compares the relative impact of Third World nations and industrial nations on the marine environment.
Biological Treatment Technologies: Microorganisms and Metabolism
From the polar ice caps to the bottom of the sea, microorganisms that provide the backbone of biological treatment are becoming our greatest ally in the quest for a cleaner environment. The microbial kingdom is comprised of organisms ranging from s...
Chemical Treatment Technologies: Benign by Design, Biomonitoring, and Enforcement
The future of chemical treatment technology is striving to attain the reduction of waste at its source, and seeking to improve the monitoring of that which is discharged.
