In this proposed MIP project investigates the economically relevant crops canola, corn and wheat can be used one hand to heavy metal contaminated sites sanener and also for the production of bioenergy. The research study the optimization of metal uptake by plants and the economic relevance of phytoremediation as a remediation option for heavy metal contaminated site. The industrial partners will focus on quantifying and optimizing the recovery of energy and heavy metals from contaminated biomass by fermentation, gasification, combustion in a combustion plant, a smelter processing and biodiesel production. Through a collaboration between research and industry partners, the energy balances and percentage of heavy metals in the bioenergy and waste products will be compared for the different energy processing. Moreover, it will be given to how these different techniques can be combined in order to obtain an optimal recovering of the energy and heavy metals from the contaminated biomass and derived products, such as digestate, filter cake, and bioethanol. All these results will lead to the establishment of requirements to build these energy processing and the associated inversterings- and operating costs. This information will finally lead to a idustriële valorization of the process for the simultaneous removal of heavy metals from the environment, and the production of (bio) gas, heat, electricity, and bio-diesel from rapeseed, maize and wheat
