Aquests biopol\u00edmers es troben a les c\u00e8l\u00b7lules en forma de gr\u00e0nuls i actuen com a reserva d’energia i carboni.<\/p>\n

En general, els PHA presenten propietats compatibles al polietil\u00e8 (PE) i al polipropil\u00e8 (PP).<\/p>\n

Els tres polihidroxialcanoats m\u00e9s importants s\u00f3n el poli (3-hidroxibutirat) (PHB<\/strong>), el polihidroxivalerat (PHV<\/strong>) i el polihidroxihexanoat (PHH<\/strong>). Diverses empreses estan involucrades en la producci\u00f3 de PHA. Actualment el mercat \u00e9s relativament petit, per\u00f2 s’espera que creixi significativament. Les aplicacions t\u00edpiques dels PHA inclouen articles de vaixella d’un sol \u00fas com gots, coberts, safates, plats de menjar i recipients de menjar. Algunes altres aplicacions (potencials) inclouen l\u00e0mines de retenci\u00f3 de s\u00f2ls i altres pel\u00b7l\u00edcules agr\u00edcoles, bosses d’escombraries i de compres, i l’\u00fas com a material d’embalatge en general. Els PHA tamb\u00e9 es poden filar en fibres que es podrien fer servir per a la fabricaci\u00f3 d’articles de tela d’un sol \u00fas biodegradables: teixits (woven) i teixit sense teixir (non woven), com ara sutures quir\u00fargiques. Altres aplicacions biom\u00e8diques (potencials) inclouen sistemes d’administraci\u00f3 de f\u00e0rmacs (microc\u00e0psules o microesferes) i dispositius m\u00e8dics implantats biodegradables.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
