Project summary

Societies have historically disposed of vast quantities of industrial, municipal, metallurgical and mining waste into the ground. Generally considered as a legacy waste issue, this research project seeks to reconsider waste repositories as “resource hubs” for future recovery of valuable materials and energy.

The research project sought to explore whether energy, valuable elements, and elements used in clean energy and other environmental applications can be recovered by leaching and other treatments whilst the material lies in situ. Not only would this reduce the need for conventional mining of valuable ores, it would avoid the need to actively excavate the waste, thereby potentially minimising ecological and environmental impacts.

In situ leaching could potentially sidestep many problems involved in extraction of materials and energy from waste repositories, and this could have important consequences not only in the UK but around the world. The processes investigated are anticipated to have substantially lower environmental and human health impacts in comparison to retrieval of resources by 'conventional' dig-and-process mining of the same wastes.

Researchers in the Centre for Sustainable Environments and Planning are examining the environmental, human and ecological impacts of the technology. We are also working with the Science Communication Unit to explore their acceptability to residents and other stakeholders.
