    Everything will be performed by the development of predictive models, the adaptation of energy consuming system to their optimal operating point, reduction of the gap between predicted and real consumption by the use of statistic models, search for correlations between energy and productive parameters, identification of inefficiencies and prescription of proceedings to their correction.

    Circular economy

    Development of projects based on eco-innovation and circular economy to transform linear productive models towards green circular economy. For that purpose, we follow the European Union Action Plan for Circular economy, focusing on priority areas: i) plastic; ii) crucial raw materials; iii) food waste; iv) biomass and bioproducts; y v) building and demolition.

    Monitoring, tracking and measurement of circular economy strategies by specific indicators—process circularity— by the use of environmental management tools.

      BIOGAS: NEW OPTIMISATION METHODS FOR ANAEROBIC DIGESTION PROCESS

      In addition to the research on pre-processing adapted to the characteristics of every single waste, the development of post-processing to reduce the effluent’s nitrogen load without increasing costs and the optimisation of anaerobic digestion process by modifying operating parameters, this line of work is focused on the development of new digester fluid-dynamically optimised models and the development of microstructures which allow to increase the biomass density in a complete mix reactor.

      This will allow to develop new compact digesters with short retention time which will enable the biogas plant industrialisation, minimising installation and operation costs and ensuring an optimal production of biogas.

With this, waste becomes another resource for economic development, contributing to the concept of circular economy. Material pre-processing is also studied as well as the use of additives to get new improved biofuels with the purpose of reducing dross and sintered production and emissions (gas and particulate materials) to the atmosphere.

This aspect deals with use limitation of these fuels both from the technical and operational point of view. At the same time, it also studies the normative and regulation constraints both in ground and naval framework.
