Field site A: Decentralized wastewater phytotreatment and phosphorus removal systems.
The PhytoVal project is located at Saint-Roch-de-l’Achigan, one hour drive north to Montréal. The aim of the project is to develop novel wastewater treatment systems using phytotechnologies. Two different approaches are being developed: 1) willow constructed wetland 2) willow plantations in short rotation coppice (SRC). These systems will also allow the recovery and valorization of water treatment resources, in the form of water, energy, organic matter and nutrients. Experimentation is conducted at a pilot scale on the site of a wastewater treatment plant but also in the laboratory to identify and better understand the treatment mechanisms of phytotechnology. In addition to this, the trip will also visit field trials of our close collaborator and leading provider of willow cuttings, Agroenergie in nearby Saint-Roch-de-l'Achigan.

Field site B: Phytoremediation of peri-urban brownfields
– In partnership with the City of Montréal (located at the industrial east end of the island of Montréal, 20 min’s drive going east from downtown).
The City of Montréal is focused on improving and employing green technologies in the coming years. The Plant Biology Research Institute has established a pilot-scale phytoremediation field test (1 ha per year; project of 4 years) to remediate medium to highly contaminated brownfields located in this industrial sector of the City. Different hybrid poplars and willows cultivars, as well as herbaceous plants were established in 2016 (site 1) and 2017 (site 2). Biomass production and phytoremediation potential of these plants are being assessed every year. The City of Montréal plans to use the biomass produced to promote the development a green chemistry sector locally.
