The proposed research seeks to undertake scoping work with academia and industry to develop a new and exciting research field related to mining resources from landfill that seeks to address the following central question: Can resources (materials of value e.g. metals, rare earth elements, plastics, energy) be recovered by leaching waste repositories whilst the material lies in situ, thus avoiding the need to actively mine the material? The fundamental geoscience research question that underpins this is: How can we understand and manipulate the in situ biogeochemistry of the waste within the repository to solubilise resources and recover them through leaching?The concept and technology of in situ leaching has been developed in the mining industry for recovery of uranium and copper, and is done by circulating solutions to extract the elements and/or stimulating and enhancing microbial leaching. No-one has looked at the possibility of transfering this concept for application to recovery of resource from waste repositories. Wastes display diverse compositions, mineralogies, textures very different to that of ores and thus will require new science to understand and develop leaching methods to solubilise valuable components.We will during the scoping stage be considering resource extraction the full range of wastes currently in UK landfills including industrial snd commercial waste (anticipated to be metal-rich), incinerator and fuel ash, mineral wastes, municipal waste and agricultural wastes to examine the idea of in situ leaching. We are particulary keen to identify during the grant which types of landfilled waste streams might be relatively enriched in certain resources and focus the full research proposal on recovery from these wastes. We envisage that in situ leaching could sidestep many of the problems that prevent realisation of the resource potential of former landfill sites, with important impacts not only in the UK but internationally. Furthermore, our aim is to not only investigate means to recover resource through in situ leaching but to also investigate how we can appropriately benchmark such processes (which we believe will have substantially lower environmental and human health impacts) in terms of life-cycle, human health and ecosystems service costs for comparison to retrieval of landfilled resources by 'conventional' dig-and-process landfill mining and against conventional mining of the same resources.

拟议的研究旨在与学术界和行业进行范围的工作，以开发与垃圾填埋场采矿资源相关的新的令人兴奋的研究领域，该研究试图解决以下中心问题：可以通过浸出废物存储库来恢复材料，从而避免使用该材料，从而避免使用材料，从而恢复了材料，从而可以恢复有价值的资源（稀土元素，塑料，能量），从而恢复了材料？基础上的基本地球科学研究问题是：我们如何理解和操纵仓库内的废物的原位生物地球化学，以通过浸出来解决资源并恢复它们？在矿业和铜的恢复中，在矿业中开发了现场浸出的概念和技术，以恢复型元素，并提高循环范围和/或提取元素或/或/或/或/或/或/或/或/或/或/intereand each and and and and/neach或/或/intereand and/intere and and and and and/neach或/inter -each或/inthere and and and/neach and/neach或/或/inthere each and/neach and and and/neach。没有人会考虑将此概念转移到从废物存储库中恢复资源的可能性。废物表现出各种成分，矿物质学，质地与矿石的质地截然不同，因此需要新科学来理解和开发浸出方法，以溶解有价值的成分。在范围内，我们将考虑资源提取资源，考虑到目前在英国垃圾中的全部废物，包括工业浪费，包括金属燃料和燃料，燃料，燃料，燃料，燃料，燃料，是金属燃料，分别是燃料，燃料，燃料，分别是燃料，燃料，燃料，燃料，分别是燃料的燃料，废物检查原位浸出的想法。我们特别热衷于在赠款期间确定哪些类型的填埋废物流可能相对丰富在某些资源中，并将完整的研究建议集中在这些废物中的恢复上。我们设想的是，原位浸出可能会避开许多阻止前垃圾填埋场资源潜力的问题，不仅在英国而且在国际上产生了重要的影响。此外，我们的目的不仅要调查通过原位浸出来恢复资源的方法，还要调查我们如何在生命周期，人类健康和生态系统的服务成本中适当基准（我们认为这将在环境和人类健康的影响方面都有大大降低的环境和人类健康影响），以通过“常规挖掘”的资源来回收降级的差异和分钟，并将其用于降低了较少的销售量，并分享了landfill的销售，并分享了landfill的分钟。
