In WP1 NTUA is involved in T1.4, where with the support of ICCS, will identify and integrate of alternative & sustainable fuels and feedstocks as replacements for fossil fuels for industrial use. In WP4 NTUA is leading T4.5. During this task, a pilot scale pyrogasification chamber with a targeted input of 50 -100 kg per day will be designed. The chamber will operate with steam to produce chlorinated hydrocarbons at medium-high temperatures between 550 – 650 °C with the targeted feedstock being a shredder Heavy Fraction product. The reactor will operate using a rotating feeding auger for continuous and undisrupted feeding, which is a very useful and applicable technology in case of a potential scale up. The biorefinery/ bio-distillery that would operate downstream of the reactor will utilize established operations like filtering, condensation, and scrubbing for the extraction of targeted compounds. These processes will be followed by catalytic cracking of selected larger molecules into valuable compounds of interest. In principle catalytic cracking process are used extensively in distilleries, but due to the specific nature of the targeted chlorinated hydrocarbons this will be an innovative part of the system. The use of pyrolysis bioproducts like biochar as catalytic material will promote the circularity and will minimize the final residues of the process. In WP5 NTUA will facilitate the integration of a GHG-energy prediction tool that will support the implementation of the Digital Twin on the DC#3. The tool that will be used is called C-FOOT CTRL, and it is a software tool consisting of an extended database and a biochemical simulation model able to estimate time variation of biogas production, the oxygen and energy consumption in each unit of a WWTP and the direct and indirect greenhouse gas emissions. The model will be used for monitoring, control, and mitigation of the carbon footprint of Demo’s WWTP. In WP6 NTUA will take part in T6.1 and the evaluation of different resources to increase flexibility of biofuels, due to their inherent and constant quality and composition fluctuations. More specifically the availability of local, low-cost solid biomass resources (e.g. forest, agricultural & agro-industrial residues, etc.) will be evaluated by ICCS and NTUA, through the collection of regionally specific data, factors affecting availability, sustainability requirements, relevant legislation and support measures and socio-economic issues.
