Likelihood of using phytoremediation for mine-tailing management in Chile

Chile has more than 750 mine tailings across the country, mainly distributed in the northern region, which also includes a biodiversity hotspot and the driest desert in the world. So far, tailing management has included chemical and physical stabilization of tailings, exclusively. This research examined the perceived likelihood of stakeholders, namely: Academia, Industry, environmental Non-Governmental Organizations, and Government officials, in the management of tailings and explored their attitudes toward the inclusion of plants and their associated microbes, as an additional stabilization technology, through an online questionnaire (n = 43). We aimed to answer What was the perceived likelihood of stakeholders for using phytoremediation for mine-tailing management in Chile? The consensus opinion across sectors is that there is general lack of proper tailings management in Chile. There is a critical willingness to incorporate phytoremediation, with a preference for using native plants. An absence of demonstrably successful phytoremediation projects, funding and access to suitable plants are perceived to be significant limitations. Local community involvement is considered key to successful restoration of tailings.
