An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry

Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.

Dichotomy in American Western Mythology (open access)

Dichotomy in American Western Mythology

The fundamental dichotomy between savage and civilized man is examined within the archetypal Western myth of American culture. The roots of the dichotomy are explored through images produced between 1888 and 1909 by artists Frederic Remington and Charles Russell. Four John Ford films are then used as a basis for the "dichotomous archetype" approach to understanding Western myth in film. Next, twenty-nine "historical" and "contemporary" Western movies are discussed chronologically, from The Virginian (1929) to Dances with Wolves (1990), in terms of the savage/civilized schema as it is personified by the roles of archetypal characters. The conclusion proposes a potential resolution of the savage/civilized conflict through an ecumenical mythology that recognizes a universal reverence for nature.
