ISO 15270-5:2025

This document establishes the terms, definitions, methodologies, and calculations that are necessary for the recovery of compostable plastic waste through organic recycling. The document identifies the different types of organic recycling technologies used in the recovery and subsequent recycling of plastics waste arising from pre-consumer and post-consumer sources, including the recovery of waste caused by dispersion into the environment. This document also establishes the requirements and calculations to be considered in evaluating organic recycling inputs and outputs and determining output classifications for the recycling operation and the downstream integration points. The document also outlines general quality requirements to be applied in all steps of the recovery process, and provides general recommendations for inclusion in material standards, test standards and product specifications. The process stages, requirements, recommendations and terminology presented in this document are intended to be of general applicability. This document does not establish test methods and criteria for the definition of the organic recyclability (e.g. compostability) of plastic materials and products. This document does not address home composting because this gardening practice cannot be classified as recycling.
