OPTIFIL, a research axis of LBE, is part of the development of environmental biorefineries by transforming organic waste and wastewater into valuable resources for the production of energy, nutrients, and bio-based molecules.
Its main objective is to shift from a linear approach to resource management towards a circular approach, by studying recovery pathways that integrate environmental and health issues from the early stages of process design, through a reverse engineering approach.

OPTIFIL investigates the fate of organic matter (C and N), nutrients (N, P, K, S), and contaminants (chemical and biological), from the inputs (organic waste and wastewater) to the receiving environments (soils, water, air). This strategy enables a multi-criteria evaluation of the resulting products to support eco-design and multi-objective optimization of treatment chains.

Three main objectives structure the research conducted within OPTIFIL:

1.    Characterization of the matter (composition, structure, reactivity) and contaminants (occurrence, interactions among them and with organic matter) and their fate within treatment pathways (e.g., biochemical and granulometric fractionation, structural characterization, spectroscopic methods, chemometric tools, indicators of safety and mobility) in order to:
2.    Understand and decorrelate the sources of variability in recovery chains to better control the quality of end-products and their effects on agroecosystems;
3.    Eco-design recovery pathways and apply reverse engineering, using multi-criteria evaluation tools and multi-objective optimization approaches.
