           The objective of this project is is to contribute at biotechnological methods with low environmental impact development (such as biosorbtion), that can be used in environmental remedial processes, and the elaboration of treatment strategies of heavy metal contaminated industrial effluents. In this context, in this project biomass waste will be used as biosorbents, resulted from ecological combustible production for heavy metal ion removal (with toxic potential or essential microelements) from aqueous medial, in concordance with the criteria imposed by the European Union.

       The technological processes studied in this project are superior to the existent technologies, from a sustainability point of view, as well as implementing costs. Also, improving the removal efficiency of heavy metal ions from aqueous media will be pursued, and via these results obtained in this project will offer a capitalization alternative of these kinds of biomass waste.

      The general objective of this project is the evaluation of the applicative potential of heavy metal ions biosorbtion processes using biomass waste (resulting from biocombustible production) which will lead to the development of methodologies/procedures useful for environmental bioremediation processes.
