Resource and Energy Intensive Industries (REIIs) require large quantities of material and energy inputs to meet the demands of their production processes. The environmental footprint resulting from these operations is therefore substantial and must be reduced to attain more sustainable business practices. RETROFEED is targeted at modifying core process equipment in REIIs to boost energy and material utilisation efficiencies, reduce greenhouse gases (GHG) emissions and replace traditional feedstock with biobased and recycled alternatives.

Latent heat thermal energy storage (TES) contributes as an innovative technology solution to improve the overall system efficiency by recovering and storing industrial waste heat. To this end, phase-change material (PCM) selection is assisted through a decision-support system (DSS). A simplified tool based on the MATLAB® model, based on correlations among the most relevant system parameters, was developed to prove the feasibility of a cross-sectorial approach. The research work conducted a parametric analysis to assess the techno-economic performance of the PCM-TES solution under different working conditions and sectors

The present study has contemplated the current feedstock to be partially or totally replaced and the alternative feedstock or internal waste to be considered according to quality requirements, market availability, and competitive pricing. While the ceramic sector has centred its effort on the re-use of internal process waste, the aluminium sector, has focused on the introduction of a wider range of recycled raw material. The cement sector, on the other hand, has explored prospective alternatives feedstock for energy production, among which biomass and refused derived fuels can be highlighted. The steel sector intends to curtail fossil fuel dependency through employing biochar and polymeric-derived residues, such as plastic and rubber. Finally, the agrochemical sector plans to partially replace their main phosphorous source by more sustainable materials, such as ashes derived from biomass combustion and organic wastes.

The VULKANO and RETROFEED projects implement and validate an advanced retrofitting solution to improve the overall efficiency and reduce emission in intensive sectors. On this route, a novel high-temperature Phase Change Materials (PCMs)-based thermal energy storage system (TES) for industrial furnaces is evaluated to increase the energy and environmental efficiency by recovering waste heat from the combustion gases. Design details such as preliminary sizing, costs and conceptual design configuration is presented as an example of integration at industrial scale, adapted to the plant operational requirements, by searching the best conceptual design and a proper selection of core materials. A multicriteria analysis is developed and applied to select the most profitable system configuration.
