Un livre blanc publi\u00e9 en mai 2026 par Hanon Systems (une filiale de Hankook) apporte un \u00e9clairage nouveau sur un sujet de plus en plus pr\u00e9occupant pour l’environnement et la sant\u00e9 publique : le r\u00e9frig\u00e9rant R1234yf, d\u00e9sormais couramment utilis\u00e9 dans les syst\u00e8mes de climatisation des v\u00e9hicules \u00e0 travers l’Europe, se d\u00e9grade presque enti\u00e8rement en acide trifluoroac\u00e9tique (TFA) \u2014 un PFAS persistant, souvent qualifi\u00e9 de \u00ab produit chimique \u00e9ternel \u00bb \u2014 en seulement dix jours apr\u00e8s son rejet dans l’atmosph\u00e8re.

On d\u00e9tecte d\u00e9j\u00e0 des traces de TFA dans l’eau de pluie, les aiguilles d’arbres, le vin, les c\u00e9r\u00e9ales et le sang humain. Les concentrations dans les pr\u00e9cipitations suisses ont doubl\u00e9 entre 2018 et 2025. En l’absence de mesures r\u00e9glementaires, les \u00e9missions cumul\u00e9es de TFA provenant du seul parc automobile europ\u00e9en pourraient atteindre 240 000 tonnes au cours des 30 prochaines ann\u00e9es, soit 3,6 fois plus que le total des 50 ann\u00e9es pr\u00e9c\u00e9dentes.

Quel est le rapport avec la cha\u00eene du froid dans le domaine de la sant\u00e9 ?<\/strong><\/p>\n

Tout. Les PFAS s’accumulent dans le cycle de l’eau \u2014 dans les rivi\u00e8res, les nappes phr\u00e9atiques et les sources d’eau potable. Les communaut\u00e9s qui ont d\u00e9j\u00e0 un acc\u00e8s limit\u00e9 \u00e0 l’eau potable et aux soins de sant\u00e9 sont les plus expos\u00e9es aux cons\u00e9quences en aval de la contamination environnementale par les PFAS. C’est pr\u00e9cis\u00e9ment dans ce contexte que SophiA intervient : dans les pharmacies et les h\u00f4pitaux des r\u00e9gions mal desservies, o\u00f9 des infrastructures robustes et propres ne sont pas un luxe, mais une n\u00e9cessit\u00e9.
*** Traduit avec www.DeepL.com\/Translator (version gratuite) *** <\/p>\n

The Hanon white paper also carries an encouraging message: PFAS-free alternatives exist and are proven. Natural refrigerants R744 (CO\u2082) and R290 (propane) are technically ready. Over one million vehicles already operate with R744 heat pump systems \u2014 with no PFAS, no TFA, and a global warming potential of just 1. <\/p>\n

Chez SophiA, nous concevons des solutions pour la cha\u00eene du froid en suivant pr\u00e9cis\u00e9ment cette logique : choisir des r\u00e9frig\u00e9rants et des technologies qui ne pr\u00e9sentent aucun danger pour les personnes, pour l’eau et \u00e0 long terme. Car dans les communaut\u00e9s que nous servons, ce qui est rejet\u00e9 dans l’environnement finit par revenir vers nous \u2014 dans l’eau, dans la nourriture, dans notre corps. <\/p>\n
