Abstract

L'invention concerne un procédé de production d'acides organiques, tels que l'acide gluconique présent dans les rebuts, tels que des ordures et des déchets, à une sélectivité, une vitesse et un rendement élevés, afin d'utiliser efficacement les déchets en tant que ressources. En produisant des acides organiques, tels que l'acide gluconique des rebuts, tels que des ordures et des déchets, un sel inorganique, tel que du carbonate de calcium ou du carbonate de magnésium, est ajouté afin de produire une réaction hydrothermique. Par conséquent, la cellulose et la glucose contenue dans les matières de base sont sélectivement décomposées à une vitesse et un rendement élevés afin de produire des acides organiques, tels que l'acide gluconique. Les acides organiques ainsi obtenus servent de matières pour les polymères biodégradables.
