The work carried out has focused on finishing the investigation of the recyclability of welded panels, theoretically and on single-stringer coupons at laboratory scale (WP2, WP3). The accomplishment of those activities has relied on the development of some ad-hoc characterisation protocols (WP4), in order to obtain meaningful measurements of chemical composition per unit of representative samples, and on the definition of a set of decision rules and the assessment algorithm for estimating alloys compatibility and predicting their recyclability (WP3).
Experimental screening proposed in RP1 was updated, dividing the experimental plan in several steps: STEP 0: samples for pre-scrap analysis and lab furnace set-up; STEP 1: Cutting experiments, trying all possible cutting strategies on each of the four coupon configurations; STEP 2: Cutting experiments to generate materials for remelting set-up tests of different EoL strategies; STEP 3.1: Cutting experiments following the selected best possible cutting strategies to be validated by remelting and STEP 3.2: Cutting experiments for full EoL validation of coated samples. WP5 started in RP2 to define the set up for validating experimentally the outlined recycling methodology for “full" welded panels, and further fine-tune the procedures for preparing the scalable recycling procedure. Technology insights of each step were summarised in D1 at coupon level and in D22 at demopanel level.
Data on energy consumption, material flows, equipment and consumables, operational conditions, etc. were collected by the partners during the cutting, decoating and remelting experiments performed on coupon samples in RP1 and on demopanels in RP2. Those data were being used to produce Life Cycle Inventory datasets (WP6), that helped to evaluate environmentally EoL alternatives, delivering additional criteria to support selection of options, in addition to technical performance. They data were the basis for filling in standardised DCs following the template provided by CS2 Eco Design TA partners.
Apart from the abovementioned technical activities, work on communication and dissemination of project results has been done and the final versions of the Communication & Dissemination Plan, of the Exploitation Plan and of the Data Management Plan (DMP) were issued. Furthermore, a revised version of DMP, updated at month 37, is provided for the present Reporting Period. All open access datasets were published in Zenodo. The technical results were presented in an international conference and in an indexed journal.
