Description

Technical Field

[0001] The present invention relates to the field of comprehensive environmental impact tracking, and in particular to a comprehensive environmental impact tracking and prediction method, device and medium. Background Art

[0002] Comprehensive environmental impact includes the balance of green, low-carbon and circular. Green mainly refers to the toxicity to the environment, low-carbon mainly refers to the greenhouse gas emissions, and circular mainly refers to the consumption and use of resources. China's industrial green, low-carbon and circular development has gone with the trend and has successively put forward the ambitious goals of "achieving carbon peak by 2030 and carbon neutrality by 2060". In the chemical industry, there are two main aspects to reduce carbon emissions. Upstream companies mainly conduct energy evaluation and control costs and prices based on the evaluation results. Mid- and downstream companies mainly use material recycling and biofuels. The recycling of materials has gradually become a hot topic. Recycling is mainly divided into biological recycling and technical recycling. "Biological recycling" refers to the degradation of degradable bio-based polymer materials into carbon dioxide and water after use, and then converted into biomass for preparing polymer materials through photosynthesis. "Technical recycling" mainly refers to recycling, including physical reuse and chemical reuse. Once the chemical reuse of waste polymer materials makes a breakthrough, fossil-based polymer materials will usher in new development opportunities. The multi-life cycle process is a complex system in which closed-loop and open-loop cycles are intertwined, and has received widespread attention in recent years. At present, the evaluation of plastic recycling is limited to the single life cycle of production, use, disposal and recycling, and lacks a carbon emission tracking and prediction method for multiple life cycles that intersect with technical cycles and biological cycles, and there is no unified evaluation standard.

[0003] The existing multi-life cycle assessment methods are usually limited to tracking and evaluating the carbon footprint of products, but do not conduct a comprehensive analysis of the green and low-carbon cycle of the material range. Although the categories of environmental impact indicators of the LCA method, which is internationally recognized today, are detailed, such as human toxicity, ecotoxicity, greenhouse gas emissions, resource consumption, etc., different international organizations have formulated different standard methods, such as IPCC, CML, etc., but none of them involve specific tracking and prediction methods for green and low-carbon cycle balance modeling. Summary of the invention
