EN ISO 14855-1:2007

Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions - Method by analysis of evolved carbon dioxide - Part 1: General method (ISO 14855-1:2005)

ISO 14855-1:2005 specifies a method for the determination of the ultimate aerobic biodegradability of plastics, based on organic compounds, under controlled composting conditions by measurement of the amount of carbon dioxide evolved and the degree of disintegration of the plastic at the end of the test. This method is designed to simulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test material is exposed to an inoculum which is derived from compost. The composting takes place in an environment wherein temperature, aeration and humidity are closely monitored and controlled. The test method is designed to yield the percentage conversion of the carbon in the test material to evolved carbon dioxide as well as the rate of conversion.
Also specified is a variant of the method, using a mineral bed (vermiculite) inoculated with thermophilic microorganisms obtained from compost with a specific activation phase, instead of mature compost. This variant is designed to yield the percentage of carbon in the test substance converted to carbon dioxide and the rate of conversion.

Bestimmung der vollständigen aeroben Bioabbaubarkeit von Kunststoff-Materialien unter den Bedingungen kontrollierter Kompostierung — Verfahren mittels Analyse des freigesetzten Kohlenstoffdioxides — Teil 1: Allgemeines Verfahren (ISO 14855-1:2005)

Dieser Teil der ISO 14855 legt ein Verfahren fest, mit dem unter geregelten Kompostierbedingungen durch Messung der Menge des gebildeten Kohlendioxids und des Grades des Zerfalls des Kunststoffs am Ende der Prüfung die vollständige aerobe Bioabbaubarkeit von Kunststoffen, die auf organischen Verbindungen beruhen, bestimmt wird. Dieses Verfahren ist dafür ausgelegt, typische aerobe Kompostierbedingungen für den organischen Anteil in festem gemischtem städtischem Abfall zu simulieren. Die Prüfsubstanz wird einem Inokulum ausgesetzt, das aus Kompost gewonnen wird. Die Kompostierung erfolgt in einer Umgebung, in der Temperatur, Begasung und Feuchte genau überwacht und geregelt werden. Das Prüfverfahren dient der Feststellung der prozentualen Umwandlung des Kohlenstoffs in der Prüfsubstanz in freigesetztes Kohlendioxid sowie der Geschwindigkeit dieser Umwandlung.
Die Unterabschnitte 8.6 und 8.7 legen eine Variante des Verfahrens fest, bei der anstelle des ausgereiften Kompostes ein mineralisches Festbett (Vermiculit) mit thermophilen Mikroorganismen, die aus dem Kompost innerhalb einer spezifischen Aktivierungsphase gewonnen werden, beimpft wird. Diese Variante wurde entwickelt, um den prozentualen Anteil des in Kohlendioxid umgewandelten Kohlenstoffs in der Prüfsubstanz und die Geschwindigkeit dieser Umwandlung festzustellen.
Die in diesem Teil der ISO 14855 beschriebenen Bedingungen entsprechen möglicherweise nicht immer den optimalen Bedingungen, unter denen der maximale Grad an Bioabbau erreicht wird.

Évaluation de la biodégradabilité aérobie ultime des matériaux plastiques dans des conditions contrôlées de compostage - Méthode par analyse du dioxyde de carbone libéré - Partie 1: Méthode générale (ISO 14855-1:2005)

L'ISO 14855-1:2005 prescrit une méthode d'évaluation, d'une part, de la biodégradabilité aérobie ultime des plastiques à partir de composés organiques dans des conditions contrôlées de compostage, par mesurage du dioxyde de carbone libéré, et d'autre part, de leur désintégration à la fin de l'essai. La présente méthode est conçue pour se rapprocher des conditions de compostage aérobies caractéristiques de la fraction organique des déchets municipaux solides non triés. Le matériau d'essai est exposé dans le cadre d'un essai de laboratoire à un inoculum provenant d'un échantillon de compost. Le compostage aérobie a lieu dans un environnement où la température, l'aération et l'humidité, en particulier, sont étroitement contrôlées et maîtrisées. La méthode permet d'accéder au pourcentage et au taux de conversion du carbone contenu dans la substance à analyser, en dioxyde de carbone libéré.
Elle spécifie également une variante de la méthode utilisant un lit minéral de vermiculite, ensemencé par des micro-organismes thermophiles obtenus à partir d'un compost à une phase d'activation spécifique, à la place d'un compost mature. Cette variante a pour objet de permettre d'obtenir un pourcentage et un taux de conversion du carbone de la substance d'essai en dioxyde de carbone dégagé.
