塑料 塑料废弃物回收和再循环指南 第5部分：有机/生物循环

[中文适用范围]： 本文件规定了通过有机回收方式回收和再利用标有“工业堆肥”标签的塑料制品和材料废弃物所需的术语、定义、方法和计算方式。文件明确了用于从预消费和后消费来源中回收和后续再利用工业堆肥塑料废弃物的各种有机回收技术。同时，文件也建立了在评估有机回收输入和输出、并确定回收操作及下游整合点的输出分类时应考虑的要求和计算方法。本文件还概述了在回收过程所有阶段中应遵循的一般质量要求，并为纳入材料标准、测试标准和产品规格提供了通用建议。文件中所述的工艺阶段、要求、建议和术语旨在具有普遍适用性。本文件不涉及定义塑料材料和产品有机可回收性（如可堆肥性）的测试方法和标准。本文件适用于那些已被相关参考标准（如ISO 17088、ISO 18606）归类为适合通过有机回收方式进行回收、并因此被标记为“工业堆肥”的塑料废弃物。这些产品通常称为“工业堆肥”（如可堆肥袋、可堆肥餐具），意思是“适合有机回收”，无论回收所采用的技术（如堆肥、厌氧消化与堆肥结合，或仅厌氧消化）。本文件未涉及家庭堆肥，因为该园艺实践不能被归类为回收。 [外文原描述]： This document establishes the terms, definitions, methodologies and calculations that are necessary for the recovery and recycling of waste from plastic products and materials labelled as industrially compostable through organic recycling. It identifies the different types of organic recycling technologies used in the recovery and subsequent recycling of industrially compostable plastics waste arising from pre-consumer and post-consumer sources. It 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. This 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 refers to plastic waste deriving from products that have been classified as suitable for recovery through organic recycling by the relevant reference standards (e.g. ISO 17088, ISO 18606), and therefore labelled as industrially compostable. These products are generally called “industrially compostable” (e.g. compostable bag, compostable tableware) meaning “suitable for organic recycling”, independently of the treatment technology used for recycling (whether it is composting, or a combination of anaerobic digestion and composting, or only anaerobic digestion). This document does not address home composting because this gardening practice cannot be classified as recycling.
