ECHA: More than 5 600 comments on PFAS restriction proposal

More than 4 400 organisations, companies and individuals submitted comments and information on the proposal to restrict per- and polyfluoroalkyl substances (PFAS) in the European Economic Area.

At the end of the consultation on 25 September, ECHA had received more than 5 600 comments from more than 4 400 organisations, companies and individuals.

The comments will be checked by ECHA's scientific committees for Risk Assessment (RAC) and Socio-Economic Analysis (SEAC), and those providing relevant evidence-based information will be considered in the opinion making process.

The five countries who prepared the initial proposal will also review the consultation input and may update their initial proposal based on it.

Many comments submitted during the consultation are already published on ECHA’s website. Information indicated as confidential by the consultee is not made public. Comments received very close to the deadline are currently being processed and will be published shortly.

Next steps
RAC and SEAC are evaluating the proposed restriction and considering the relevant information received through the consultation. The committees develop their independent, scientific opinions over a series of meetings, where draft opinions are discussed. Attention is given to all aspects and impacted sectors.

ECHA will deliver the final opinions to the European Commission in the shortest possible timeframe, while ensuring proper scrutiny by the scientific committees. Once the committees adopt their opinions, they will be communicated to the public.

The Commission, together with the EU Member States, will decide on the restriction.

Background
The restriction proposal was prepared by authorities in Denmark, Germany, the Netherlands, Norway and Sweden. It was submitted to ECHA on 13 January 2023. It aims to reduce PFAS emissions into the environment and make products and processes safer for people. The six-month consultation ran from 22 March to 25 September 2023.

Nanomodified polymerstent: Novel technology for tumour therapy

  • Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

Das interdisziplinär aufgestellte Forscherteam von der TU Dresden, bestehend aus Dr.-Ing. Dilbar Aibibu und Dipl.-Ing. Lukas Benecke vom Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik (ITM) der TU Dresden sowie Prof. Dr. med. Marcus Neudert und Dr.-Ing. Zhaoyu Chen von der Klinik und Poliklinik für Hals-, Nasen- und Ohrenheilkunde (HNO) der Medizinischen Fakultät der TU Dresden, wurde für die Entwicklung eines biomimetischen Trommelfellimplantats, die maßgeblich in dem IGF-Forschungsvorhaben 20533 BR umgesetzt worden ist, für den diesjährigen Otto von Guericke-Preis der AiF nominiert.

Prof. Chokri Cherif, Institutsdirektor des ITM freut sich mit seinem Team sehr über die kontinuierlichen interdisziplinären Forschungserfolge auf dem stetig wachsenden Forschungsfeld der faserbasierten Biomedizintechnik, die am ITM in enger Kooperation mit Medizinern und Anwendern stetig erzielt werden. „Bereits im letzten Jahr wurden wir mit der Entwicklung neuartiger textiler Herzklappenprothesen als eines der drei Finalistenteams des Otto von Guericke-Preises 2020 geehrt. Die Nominierung für diesen hochkarätigen Preis ist eine erneute Bestätigung für den Bedarf an unserer praxisorientierten Forschung und eine besondere Würdigung, aber gleichzeitig auch weiterer Ansporn.

Über 30 Millionen Menschen leiden jährlich an den Folgen eines defekten Trommelfells. Ohne fachmedizinische Behandlung kann dies zu dauerhaften Schäden und schwerem Hörverlust führen. Zur Rekonstruktion des Trommelfells, der sogenannten Myringoplastik, werden heute körpereigene Knorpelhaut, Faszie oder synthetische Materialien eingesetzt. Da deren Materialeigenschaften nicht denen des natürlichen Trommelfells entsprechen, ist eine vollständige Rehabilitation des Gehörs damit nicht möglich.

Wissenschaftlerinnen und Wissenschaftler vom ITM und HNO-Klinik der TU Dresden entwickelten im Rahmen des IGF-Vorhabens „Simulationsgestützte Entwicklung einer flexiblen Technologie zur Umsetzung biomimetischer, langzeitresorbierbarer funktionaler und stabiler Trommelfellimplantate MyringoSeal)“ ein biomimetisch aufgebautes künstliches Trommelfellimplantat, das die körpereigenen Schwingungseigenschaften exakt wiedergibt. Die neuartige Membran ermöglicht eine vollständige Wiederherstellung der Schwingungseigenschaften des Trommelfells. Die Herstellung solcher Implantate ist mithilfe der Elektrospinntechnologie aus den Biomaterialien Seidenfibroin und Polycaprolacton möglich.
