Report of cross-sectoral replication of RETROFEED technologie



https://app.h4c-community.eu/contents/93/detail-content/rwjitJIBm07gu5S0Dc7N

This report contains the analysis of the replicability of the different RETROFEED solutions. Real data obtained at the demo sites has been used to make a realistic projection of the feasibility of the implementation of these solutions. Initially, an assessment of the applicability of the RETROFEED solutions to the different targeted sectors (ceramics, cement, aluminium, steel, and agrochemical) has been conducted. Each solution replicability feasibility in the sector at which each demo site belongs is provided.

CREAToR – Extractive extrusion process performed with all provided material classes



https://app.h4c-community.eu/contents/93/detail-content/sAgTtZIBm07gu5S0yc6y

In this report a continuous extrusion technology, the so-called extractive extrusion process, is presented to demonstrate the potential to remove HBCD fire retardants from a polymer matrix by the use of supercritical CO2 (sc-CO2) with and without co-solvents. The extractive extrusion process technology is an advanced extrusion process. Its unique key characteristic is the melt purification via sc-CO2 which is brought in and out of the extruder in a supercritical state. The nonlegacy substance, e.g. HBCD, is dissolved in the sc-CO2 and redirected out of the extruder. The focus of the study is to extract HBCD from a polystyrene (PS) foam material, which was used as isolation material in the building sector in the previous decades. Apart from building isolation materials, HBCD was also detected in ABS coming from WEEE and fridges. However initial screening trials showed only low amounts of HBCD in ABS. Consequently, the ABS fraction has not been used as second grade to optimize the extractive extrusion process for the removal of HBCD.
