– An integrative approach to increase the value of brownfields by phytoremediation

 - 

Urban brownfields are often overlooked due to the negative perception associated with them: residual contamination, low economic value, presence of undesirable species and lack of aesthetic concerns. However, by promoting an appropriate use of these lands, brownfields have the potential to generate economic and environmental benefits. Since 2016, the Institut de recherche en biologie végétale is conducting research studies, in the Eastern part of the Montreal Island, on biomass production and phytoremediation on urban brownfields to implement their sustainable use. Many fast-growing species, such as willow and hybrid poplars, have shown that sustainable biomass production is possible on these lands. Furthermore, the integration of landscape architecture elements has fostered social acceptability of the project.
