The invention provides a process for remediation of sites contaminated with metals such as former industrial sites and mines. In particular the invention provides a process for site remediation comprising the steps of: (a) adding metal-binding particles to a site containing one or more metal contaminants such that at least some of the one or metal contaminants are sequestered by the particles, and (b) populating the site with plants. The use of the particles of the present invention in association with plants, and microbiota associated with the plant roots can achieve sustainable phytostabilisation of contaminated sites.
