Putting waste to work (an engineer's obligation to the environment)

Article Abstract:

The use of recycled waste products in engineering helps to protect the environment. It also solves the problem of waste disposal. The resources generated by waste recycling in turn helps to preserve natural resources by reducing their demand. The most commonly used waste product is fly ash. It is used in concrete and fertilizers, and to stabilize highway embankments. Rubber obtained from scrap tires is used in road construction. Scrap tires are also used to build wall and stabilize soil embankments. Gas can be produced from garbage and electricity from sewage effluents.

Washington water project safeguards environment

Article Abstract:

The Marysville, WA, pipelineinstallation marked the first time that such a project was subject to provisions of an environmental impact statement and a mitigated determination of non-significance. The failure of one of the city's main water wells necessitated the project while new federal drinking standards posed additional design constraints. The engineers worked with wetlands biologists and wildlife officials to ensurethat the the project did not endanger the environment nor the creek where they worked.
