Hyperaccumulation of lead using Agrostis tenuis

Abstract In recent years the quest for a circular economy approach and upcycling of secondary raw materials have been pushed in global political agenda. Increased interest has taken by recovery from sludges, brines, contaminated waters other media, all included larger umbrella identified as “low-grade” mineralisation. Contaminated soils an interesting role this process, various methodologies developed using chemical, bacteriological pyrometallurgical cleaning procedures. However, these procedures involve movement high volume disruption industrial landscape; furthermore, they often require use hazardous solvents energy processes. This work proposes to identify less impactful methods aimed at metals mining areas while preserving landscape avoiding environmental impacts such increase CO 2 transport hazard through solvents, takes particular importance heritage status. particular, focuses on Agrostis tenuis , autochthonous species UK, “mining tool” removal lead. The selection plant is due its visually non-invasive nature, already present areas, it doesn’t grow above 10/15 cm also grows very fast can be easily harvested with existing agricultural equipment. experiments results presented paper indicate: (1) Tenuis shows ability adjust contamination accumulation capacity; (2) metal collected fully transposed aerial part stable compound form consequently further processed.
