Through decades of mining and oil exploration, over 10,000 contaminated sites are found in Canada with toxic levels of heavy metals and harmful contaminants. In many cases, the contamination is on local farmland and the impacts on the environment and especially on the native communities and Indigenous inhabitants is devastating. This project will be committed to use abandoned mines in order to provide biomass by planting poplar trees which are resistant to the contaminations in order to lead biomass to the biohydrogen production. In this way, along with greenization of the polluted soil and marginal lands, the biomass of poplar leaves is considered as a sustainable approach for biohydrogen production as a promising energy resource. In order to achieve these goals, experts will set up a system based on the selected target mine heavy metal levels to grow the most promising cultivars of poplars and consequently, the biomass system.
