New, natural, self-renewing, and low-cost, evapotranspiration (ET) covers for landfills provide a solution to landfill waste that is clean, green, and economical. Evapotranspiration Covers for Landfills and Waste Sites examines the concept theory and the practical proof, then explains the technology, design, and application. It delineates the essential technology that governs successful application of ET covers and discusses how the technology meets the requirements for covers on landfills, mining waste, and other sites.
The book describes the design, construction, and maintenance of innovative ET covers for landfills and waste. The author discusses why several vegetative covers have failed and provides simple, inexpensive solutions. He examines the design and construction of ET covers and other methods, highlighting their differences and successful alternative construction methods. The text contains the first proposed performance measurements for conventional and innovative landfill covers based on the data collected at more than fifty-five sites. This data also provides the basis for an assessment of landfill cover performance, design, and the creation of the site-specific performance criteria presented in Evapotranspiration Covers for Landfills and Waste Sites.
This is the first resource to explore the technology required to apply the ET cover concept to landfill waste, spill sites, mineland restoration, and similar waste sites. After thoroughly describing the concept, technology, design, construction, and maintenance of ET covers, the book explains how this cost-effective, practical, easily maintained, and self-renewing biological system should maintain its effectiveness for centuries.
