National, regional, and local governments are implementing the practice of sustainable management of aggregate resources in only a few parts of the World, and there are few or no guidelines for the aggregate industry to follow. Nevertheless, the aggregate industry can independently utilize sustainable management techniques to achieve the goals of meeting their needs for reserves without compromising the ability of future generations to meet their needs. Lafarge, a major aggregate producer in the area near Denver, Colorado, USA, submitted a proposal to enlarge their quarry holdings through an exchange of land owned by the company for dedicated open space land owned by Jefferson County, Colorado. During the application process, Lafarge employed three key tenets of sustainable management that relate to the aggregate industry: 1) industry must be a responsible corporate members of the community, 2) resource development must meet the needs of both the company and the community, and 3) all stakeholders must have the opportunity to participate in the process. A number of operational concepts necessary for the sustainable management of aggregate resources grew from these tenets.
