The historical reservoir for the materials used by our technological society has been virgin stocks (ore bodies, mineral deposits, and the like). For a variety of reasons, those stocks may become inadequate or unavailable at some times or places in the future. Other reservoirs exist, however, a principal one being products stored or discarded over the years by corporations and individuals. These latter reservoirs might become very important in the next few decades of rapid population growth and resource use, but we know little about their total abundance and the chemical and physical forms in which they exist. In this research, we will evaluate current and historical flows of specific materials (selected from copper, silver, zinc, cadmium, ABS polymer and construction timber), estimate the stocks available in different types of reservoirs, especially industrial and municipal landfills. To do so, we will draw largely on information now scattered across a number of data depositories and centers of excellence: mineralogical and geological records, economic data, industrial association publications, environmental records, and so on. Historical records should permit the assessment to be extended, at least approximately, to include the entire 20th century. The expectation is that there will be seen to be substantial utility in material stock and flow information and that a number of technological and policy actions may be guided by the results. In particular, it is anticipated that it will be most useful to evaluate non-virgin materials reservoirs as potential sources of industrial materials for the next millennium.

我们的技术社会所使用的材料的历史储存库一直是未开发的资源（矿体、矿床等）。由于各种原因，这些库存可能会在未来的某些时间或地点变得不足或不可用。然而，也存在其他储存库，主要是公司和个人多年来储存或丢弃的产品。在人口快速增长和资源利用的未来几十年中，后一类水库可能变得非常重要，但我们对它们的总丰度以及它们存在的化学和物理形式所知甚少。在这项研究中，我们将评估特定材料（从铜、银、锌、镉、ABS聚合物和建筑木材中选择）的当前和历史流量，估计不同类型水库（特别是工业和市政垃圾填埋场）的可用储量。为此，我们将在很大程度上利用分散在许多数据存储库和卓越中心的信息：矿物学和地质记录、经济数据、工业协会出版物、环境记录等等。历史记录应该允许评估扩展，至少大约，包括整个20世纪。预期的结果是，材料库存和流量资料将会有很大的用处，一些技术和政策行动可能会以这些结果为指导。特别是，预计评价非原始材料储层作为下一个千年工业材料的潜在来源将是最有用的。
