Description

Technical Field

[0001] The present invention belongs to the technical field of carbon footprint accounting, and particularly relates to a method and system for calculating the carbon footprint in the production process of needle-punched geotextile products. Background Art

[0002] In many industrial fields, geotextiles, as an important material widely used in infrastructure construction such as civil engineering, water conservancy projects, and transportation projects, the carbon footprint in their production and use processes has received increasing attention. Needle-punched geotextiles are a type of geosynthetic material formed by carding short fibers or long filaments into a web and then using a needle punching process to entangle and reinforce the fibers. In the production process of needle-punched geotextiles, processes such as fiber carding, web laying, and needle punching require a large amount of electricity to drive various mechanical equipment, and the manufacturing, maintenance of equipment, and waste treatment during operation will indirectly or directly lead to greenhouse gas emissions.

[0003] However, existing carbon footprint calculation technologies have many limitations when faced with the production process of specific products such as needle-punched geotextiles. On the one hand, traditional calculation methods often lack a detailed analysis of the production process of needle-punched geotextiles, and fail to fully consider the energy consumption characteristics of specific machinery and equipment in each production process and their corresponding carbon emission details. For example, it is difficult to accurately calculate the power consumption differences of different power motors at different operating times and the resulting precise carbon emissions. On the other hand, for auxiliary equipment in the production process, such as dust removal devices, which consume energy and generate carbon emissions during operation, and also play a positive role in reducing pollutant emissions in the production environment, existing technologies are difficult to comprehensively and reasonably evaluate their overall impact on the carbon footprint. In addition, in terms of data collection and processing, the lack of a systematic and targeted data collection framework and an accurate and timely updated carbon emission factor database greatly reduces the accuracy and reliability of the carbon footprint calculation results, and cannot provide practical energy-saving and emission-reduction decision-making basis for enterprises, making it difficult to meet the urgent needs of enterprises for accurate calculation and effective management of their carbon footprints under the increasingly strict environmental protection regulations and market green competition pressure.

[0004] Therefore, there is an urgent need for a method and system for calculating the carbon footprint in the production process of needle-punched geotextile products to fill the gap in this field and provide strong technical support for the green and low-carbon transformation of the geotextile industry.
