Introduction
GB/T 41638.2-2023 "Plastics - Carbon Footprint and Environmental Footprint of Biobased Plastics - Part 2: Material Carbon Footprint - Amount (Mass) of CO2 Incorporated from Air into Polymer Molecules" is a national standard in China that focuses on measuring the carbon footprint of biobased plastics. This standard specifically quantifies the amount of carbon dioxide (CO2) that is absorbed from the air and incorporated into the polymer molecules during the production process.
The purpose of this standard is to provide a comprehensive and standardized methodology for assessing the environmental impact of biobased plastics. By measuring the material carbon footprint, it enables manufacturers and consumers to make informed decisions regarding the environmental sustainability of biobased plastics.
The standard outlines the procedures and calculations required to determine the amount of CO2 incorporated into the polymer molecules. It takes into account factors such as the type of biobased feedstock used, the production process, and the carbon content of the feedstock. By accurately quantifying the material carbon footprint, this standard helps in evaluating the overall environmental performance of biobased plastics and comparing them with conventional plastics.
Adhering to GB/T 41638.2-2023 ensures transparency and consistency in assessing the carbon footprint of biobased plastics. It enables companies to better understand and manage their environmental impact, supporting the transition towards more sustainable and eco-friendly plastic materials.
