The TAILENG Foundation is dedicated to inspire the next generation to pursue education in the field of earth resources engineering and educating professionals on the best practices, all in order to promote better environmental stewardship and sustainability. In particular, the adequate management of waste residuals from mining related activities is a key aspect of earth resources engineering. in this context, the TAILENG foundation focuses on advancing the state of knowledge and practice in the design of tailings and industrial waste storage facilities Recent catastrophic failures of tailings storage facilities, such as the Fundao dam failure, which killed 19 people and, historically, is considered the largest environmental disaster in Brazil, highlight the need for an improved understanding of the engineering properties of tailings. The 2008 Kingston, Tennessee failure of a coal ash storage facility is another example of the severe environmental impacts of the failure of a tailings or industrial waste storage facility. These and other recent failures highlight the need to better understand the behavior of intermediate, or transitional, soil that include mine tailings, coal combustion by-products, and other industrial sludge to develop robust design, operation, and closure plans for waste storage facilities.
