introduction

The plastics industry is an important pillar industry of the national economy. With the rapid development of my country's plastics industry and the extensive use of plastic products, the demand for plastics has increased significantly. Recycling is an important issue facing the industry. It is one of the ways to achieve sustainable development of plastics and also a way to solve environmental problems such as "white pollution". Questions provide an effective approach. Plastic recycling is a systematic project that aims to save resources (original raw materials, water and energy) while reducing the impact on air, water and soil. Reducing the impact of plastic recycling on the environment and human health, while reducing carbon emissions, is one of the effective means to achieve carbon neutrality. The impact can be assessed through the life cycle of a single recycled plastic. In order to make recycling an environmentally friendly choice, it is recommended to meet The following prerequisites. --- The plastic recycling options considered are expected to have smaller environmental impacts than other options; --- Existing or potential markets enable the recycling process to be recycled on a sustained industrial scale; ---Design collection and sorting schemes appropriately to the types of recyclable plastic materials, current recycling technologies and identified markets Reasonable matching of needs. The purpose of this document is to describe the necessary procedures for the production of recycled plastics and to provide traceability proof. We use recycled plastic materials from traceable recyclable plastics to provide end users with quality guaranteed products. During the production and traceability of recycled plastics, it is advisable to classify recyclable plastics according to the needs of enterprises or end markets for different specific characteristics of recycled plastics. The material source, supply chain, pre-processing testing, recycled plastic production process, recycled plastic characterization, expected application and other attributes are analyzed for consistency and reliability. During this period, the recyclable plastic material may be contaminated by other materials, thus affecting its recycling. In this situation, suppliers of recycled plastics have two options for ensuring their quality. ensuring that contaminants do not enter the recycling process through input controls or sorting equipment. The process, or the recycled plastic production party uses a reasonable process to remove pollutants and other impacts, thereby not affecting the use of recyclable plastic materials. In addition, the properties of recycled plastic materials may change due to external influences, such as historical processing and/or usage conditions, etc. Companies add virgin plastics, that is, reduce the proportion of recycled plastic materials, or try to adjust the main and auxiliary materials, additive formula or optimize The design of the plastic recycling process should eliminate or repair potential contaminants or material damage that may be harmful to the intended application. If not, its use should be controlled. Track and record the recycling and reuse process to achieve the life cycle of recycled plastics. Traceability. This document also provides an assessment of the environmental impacts of recycled plastics during their life cycle, including recycling, production, sales, use and end-of-life (discarding). Estimation method. At present, my country's recycled plastics standard system is still being established and gradually improved. This document is an important part of the recycled plastics standard system. One of the basic standards, laying a solid foundation for the gradual establishment of a complete recycled plastics standard system and the green and healthy development of the recycled plastics industry Base. Plastic recycled plastic Guidance on Traceability and Environmental Aspects Assessment

1 Scope

This document provides guidance on the traceability of recycled plastics, and gives the classification and identification of recyclable plastic materials, Material characterization and input material control, recycling production process control, recycled plastic characterization, green factory evaluation, recycled plastic identification and labeling, Traceability information composed of steps such as traceability assurance. This document also provides guidance on the environmental factor assessment method for recycled plastics life cycle, and gives the environmental factor assessment check coverage. information. This document applies to the traceability and environmental factor assessment of the entire recycled plastics process.
