Plastics — Determination of the ultimate anaerobic biodegradation under high-solids anaerobic-digestion conditions — Method by analysis of released biogas

Plastics — Determination of the ultimate anaerobic biodegradation under high-solids anaerobic-digestion conditions — Method by analysis of released biogas

ISO 15985:2014 specifies a method for the evaluation of the ultimate anaerobic biodegradability of plastics based on organic compounds under high-solids anaerobic-digestion conditions by measurement of evolved biogas at the end of the test. This method is designed to simulate typical anaerobic digestion conditions for the organic fraction of mixed municipal solid waste. The test material is exposed in a laboratory test to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The anaerobic decomposition takes place under high-solids (more than 20 % total solids) and static non-mixed conditions. The test method is designed to yield the percentage of carbon in the test material and its rate of conversion to evolved carbon dioxide and methane (biogas).

Plastiques — Évaluation de la biodégradation anaérobie ultime dans des conditions de digestion anaérobie à teneur élevée en solides — Méthode par analyse du biogaz libéré

L'ISO 15985:2014 spécifie une méthode pour l'évaluation de la biodégradabilité anaérobie ultime des plastiques basée sur des composés organiques dans des conditions de digestion anaérobie à teneur élevée en solides, par mesurage du biogaz libéré à la fin de l'essai. La présente méthode est conçue pour simuler les conditions de digestion anaérobie caractéristiques de la fraction organique des déchets municipaux solides mixtes. Le matériau d'essai est exposé, lors d'un essai en laboratoire, à un inoculum méthanogène dérivé de digesteurs anaérobies fonctionnant uniquement avec des déchets ménagers prétraités. La décomposition anaérobie a lieu dans des conditions à teneur élevée en solides (plus de 20 % de matières solides totales) et statiques non mixtes. La méthode d'essai a pour objet de permettre d'obtenir le pourcentage de carbone contenu dans le matériau d'essai et son taux de conversion en dioxyde de carbone et en méthane (biogaz) libérés. Les conditions décrites dans l'ISO 15985:2014 ne correspondent pas nécessairement aux conditions optimales permettant d'obtenir le taux maximal de biodégradation.

Plastics — Carbon and environmental footprint of biobased plastics — Part 4: Environmental (total) footprint (Life cycle assessment)

This document provides life cycle assessment (LCA) requirements and guidance to assess impacts over the life cycle of biobased plastic products, materials and polymer resins, which are partly or wholly based on biobased constituents. The applications of LCA as such are outside the scope of this document. Clarifications, considerations, practices, simplifications and options for the different applications, are also beyond the scope of this document. In addition, this document can be applied in studies that do not cover the whole life cycle, with justification, for example in the case of business-to-business information, such as cradle-to-gate studies, gate-to-gate studies, and specific parts of the life cycle (e.g. waste management, components of a product). For these studies, most requirements of this document are applicable (e.g. data quality, collection and calculation as well as allocation and critical review), but not all the requirements for the system boundary.

Plastics — Ecotoxicity testing scheme for soluble decomposition intermediates from biodegradable plastic materials and products used in the marine environment — Test methods and requirements

This document specifies test methods and evaluation criteria by addressing potential ecotoxicological adverse effects on marine organisms. Adverse effects on marine species can be caused by soluble degradation products of plastic materials such as intermediates or remaining residues resulting from the biodegradation of plastic materials that are used in products for marine applications (e.g. nets for fish farming, dolly ropes, floats, buoys and other non-fishing applications) and which are used in different marine zones, e.g. eulittoral, sublittoral or pelagic zones. The ecotoxicity testing scheme covers marine organisms from four trophic levels, primary producer, primary and secondary consumers and decomposer: — toxicity to marine algae, — toxicity to marine invertebrates, — toxicity to marine fish, — toxicity to marine microorganisms. This document is not suitable for the assessment of adverse effects caused by solid materials of any size.

Plastics — Determination of specific aerobic biodegradation rate of solid plastic materials and disappearance time (DT50) under mesophilic laboratory test conditions

This document specifies a method to determine the specific aerobic biodegradation rate of solid, non-water soluble plastic materials under mesophilic conditions. NOTE The specific aerobic biodegradation rate (which, strictly speaking, is a specific mineralization rate, implying the assessment of the conversion of organic carbon into CO2 but neglecting biomass formation) is expressed as amount of carbon mineralized into CO2, per unit time, per unit area. The method described in this document does not provide information on the ultimate aerobic biodegradability of the tested samples. Biodegradability criteria for plastic materials under mesophilic conditions are provided for example by ISO 23517, and ISO 22403. The method described in this document shall be used to determine the DT50 only when the plastic material is proven to be intrinsically biodegradable using suitable standard specifications such as ISO 23517 and ISO 22403. Furthermore, the biodegradation rate determined on plastic materials whose ultimate biodegradation has not been proven, shall not be considered as a specific characteristic of the whole material. This document only considers the evolution of CO2 as direct measurement of mineralization of the tested sample. The method described in this document may be applied also to solid materials used as a reference. This document is not applicable for “marine, soil and freshwater biodegradable” claims of biodegradable plastic materials. For such purposes, see relevant product standards if available. NOTE Although results can indicate that the tested plastic materials and polymers will biodegrade under the specified test conditions at a certain specific aerobic biodegradation rate or DT50, the results of any laboratory exposure are not directly applicable to environmental compartments including soil, marine environments and limnic areas at the actual site of use or leakage.

Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium — Method by analysis of evolved carbon dioxide

This document specifies a method, by measuring the amount of carbon dioxide evolved, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in a synthetic medium under standardized laboratory conditions to an inoculum from activated sludge under aerobic conditions. The conditions used in this document do not necessarily correspond to the optimum conditions allowing maximum biodegradation to occur, but this test method is designed to measure the biodegradation of plastic materials and give an indication of their potential biodegradability. The method enables the assessment of the biodegradation to be improved by calculating a carbon balance (optional, see Annex C). The method applies to the following materials: — natural and/or synthetic polymers, copolymers or mixtures thereof; — plastic materials which contain additives such as plasticizers, colorants or other compounds; — water-soluble polymers; — materials which, under the test conditions, do not inhibit the microorganisms present in the inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate method (see, for example, ISO 8192[1]). If the test material is inhibitory to the inoculum, a lower test concentration, another inoculum or a pre-exposed inoculum can be used.
