Introduction

GB/T 41638 "Carbon Footprint and Environmental Footprint of Bio-based Plastics" is proposed to be composed of five parts:

--- Part 1: General: The purpose is to provide information and guidance for life cycle assessment and application of bio-based products:

--- Part 2: Material carbon footprint The amount (mass) of CO2 incorporated into polymer molecules from the air: determined according to test results

The biocarbon content, which is used to calculate the CO2 reduction that can be achieved by biochar instead of petroleum carbon (material carbon footprint):

--- Part 3: Process carbon footprint quantification requirements and guidelines: Specifies the requirements for quantifying and reporting the carbon footprint of the bio-based plastics process:

--- Part 4: Environmental (total) footprint (life cycle assessment): Using the method of life cycle assessment, calculate the conversion of input materials into final products

The process carbon footprint generated during the production process enables sustainable and environmentally responsible management of carbon (carbon-based materials):

--- Part 5: Reporting and evaluation: Requirements for reporting the results of carbon and environmental footprint assessments of bio-based plastics:

Increasing the use of biomass resources in the production of plastic products can alleviate the trend of global warming and slow down the depletion of fossil resources:

At present, plastic products are mainly composed of bio-based synthetic polymers, fossil-based synthetic polymers, natural polymers and additives containing bio-based materials:

Made with additives:

Bio-based plastics are plastics that are wholly or partly derived from biomass:

Part 3: Requirements and guidelines for process carbon footprint quantification

1 Scope

This document specifies the requirements and guidelines for the carbon footprint quantification report (see ISO 22526-1) of the bio-based plastics process: This document serves as

Part of the standards related to the carbon footprint of bio-based plastic products, based on ISO 14067 and life cycle assessment standards (ISO 14040 and

ISO 14044) requirements:

This document applies to studies of the process carbon footprint (P-CFP) of plastic materials, i:e: the partial carbon footprint of a product, whether or not the results are intended

public:

This document provides the requirements and guidelines for the quantification of a product's partial carbon footprint (partial CFP): According to ISO 14067, use the specification in this document

According to the specific conditions and requirements specified, the carbon footprint of the process is studied as part of the carbon footprint:

This document specifies the analysis and calculation process and report content of P-CFP to ensure the transparency and credibility of the report:
