Phytomining and nano-synthesis: a green route to tackle soil contamination

Industrialisation and urbanisation bring a huge impact on the environment. In parallel impoverishment of resources leaves the industrialised economies to be constantly dependent from third parties for the procurement of raw materials. We aim at shifting the paradigm and switching the approach to contaminated land from an hazard to a wealth of raw material, in particular metals and metal oxides. The use of plant as mean of remediation and stabilisation of contaminated soil is very much in use in industrially contaminated lands. We aim at pushing this further into using plants as a tool for a fast selective metal mining. Additionally, after the metal collection we aim at using plants as the medium for the synthesis of high value nano-particles for the application in electronics, biomedical and energy field.

The project aims at understanding and identifying the optimal plants association to best achieve multi-selective metal collection (using targeted case studies of existing contaminated areas); the optimal treatment to obtain an effective nano-synthesis and maintain a clean biomass residue for further use and the factors/conditions to manipulate nano-particles sizes and morphologies for specific case study applications.
