Critical mineral removal from mining‐impacted waters using microalgal biomass
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

Land Degradation &Development, EarlyView.ABSTRACT Chemical compliance remains the usual endpoint for closing contaminated‐soil remediation projects, although it does not establish recovery of soil function or the durability of the post‐treatment state. This critical review examines when microbiological evidence can contribute to ecological closure decisions.

Land Degradation &Development, EarlyView.ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.
