Highlighting the Role of Archaea in Urban Mine Waste Exploitation and Valorisation
Recycling, 2023 E-materials become e-waste once they have been discarded without the intent of reuse. Due to its rich content of metals, among which many are Critical Raw Materials (CRMs), e-waste can be considered an urban mine to exploit and valorise.

Archaeology, science-based archaeology and the Mediterranean Bronze Age metals trade [PDF]
, 2000 Archaeologists often seem either sceptical of science-based archaeology or baffled by its results. The underpinnings of science-based archaeology may conflict with social or behavioural factors unsuited to quantification and grouping procedures.
