Abstract
La présente invention concerne le secteur technique du compostage et plus particulièrement du compostage aérobie, à savoir, en présence d’une grande quantité d’oxygène. L’utilisation d’un polymère superabsorbant de l’invention permet tout à la fois d’accélérer l’activité métabolique des micro-organismes présents dans le compost et de limiter les apports nécessaires en eau, évitant ainsi tout stress hydrique. Selon l’invention, le polymère superabsorbant accélérateur de compostage est mélangé au compost, de préférence immédiatement avant ou pendant le compostage, à un dosage de 2 à 30 kg par tonne, de préférence de 5 à 20 kg et est caractérisé en ce qu’il est biodégradable conformément à la Norme européenne NF EN 14995. L’invention concerne également le procédé de mise en œuvre du polymère superabsorbant biodégradable et les composts issus du procédé.
