标准范围
本文件规定了适用于有机回收的塑料和塑料制品的程序和要求。以下四个方面得到了解决:a） 堆肥过程中的分解；b） 最终好氧生物降解；c） 堆肥对陆生生物无不良影响；d） 成分控制。这四个方面适用于评估对工业堆肥过程的影响。本文件旨在作为可堆肥塑料材料和产品的标签和索赔制度的基础。本文件未提供有关塑料生物降解性要求的信息，这些塑料最终会作为垃圾进入环境。它也不适用于住户在小型设施中进行的生物处理。注？1？通过堆肥回收可堆肥塑料可以在油井中发现的条件下进行-管理的工业堆肥过程，其中温度、含水量、好氧条件、碳氮比和处理条件得到优化。这种条件通常在工业和市政堆肥厂获得。在这些条件下，可堆肥塑料的分解和生物降解速度与庭院装饰物、牛皮纸袋和食物残渣相当。注2？“可堆肥”或“市政和工业堆肥设施中的可堆肥”是本文件中被视为等同于有机可回收的表述。
This document specifies procedures and requirements for plastics, and products made from plastics, that are suitable for recovery through organic recycling. The four following aspects are addressed:a) disintegration during composting;b) ultimate aerobic biodegradation;c) no adverse effects of compost on terrestrial organisms;d) control of constituents.These four aspects are suitable to assess the effects on the industrial composting process.This document is intended to be used as the basis for systems of labelling and claims for compostable plastics materials and products.This document does not provide information on requirements for the biodegradability of plastics which end up in the environment as litter. It is also not applicable to biological treatment undertaken in small installations by householders.NOTE 1 The recovery of compostable plastics through composting can be carried out under the conditions found in well-managed industrial composting processes, where the temperature, water content, aerobic conditions, carbon/nitrogen ratio and processing conditions are optimized. Such conditions are generally obtained in industrial and municipal composting plants. Under these conditions, compostable plastics disintegrate and biodegrade at rates comparable to yard trimmings, kraft paper bags and food scraps.NOTE 2 “Compostable” or “compostable in municipal and industrial composting facilities” are expressions considered to be equivalent to organically recyclable for the purposes of this document.
