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: Carbon and environmental footprints of plastic bio-based plastics Part 2: Carbon footprint of materials incorporated from the air Amount (mass) of CO2 to the polymer molecule

1 Scope

This document specifies the carbon footprint of a material as the amount (mass) of CO2 removed from the air and fixed by polymer molecules, describing its quantification method: This document applies to plastic products, plastic materials and polymer resins made entirely or partly from bio-based materials:
