T/CPCIF 0036-2020 Green Design Product Evaluation Technical Specification for Poly tetramethylene ether glycol

Scope

Scope: This standard specifies the terms and definitions, evaluation principles and methods, evaluation requirements, and preparation methods for life cycle assessment reports of green design products of polytetramethylene ether glycol (PTMEG). This standard applies to the evaluation of green design products of polytetramethylene ether glycol produced by homogeneous polymerization and heterogeneous polymerization methods. Main technical content: Based on the principle of combining life cycle assessment with indicator evaluation, considering the entire life cycle of polytetramethylene ether glycol products, from product design, raw material acquisition, product production, product use, post-disposal recycling, and comprehensive utilization of industrial wastewater, we deeply analyze the resource consumption, ecological environment, and human health factors at each stage. We select indicators that can be evaluated at different stages to form an evaluation indicator system. Based on the characteristics of polytetramethylene ether glycol products and production processes, and considering the high social attention and the types of environmental impacts explicitly required by national laws or policies, we select key resource attributes, energy attributes, environmental attributes, and product attributes for evaluation. This technical specification selects indicators such as single raw material consumption, fresh water usage, tetrahydrofuran consumption per ton of product, methanol consumption, comprehensive energy consumption per unit product, solid waste generation, wastewater discharge per unit product, and the rate of harmless disposal of organic wastewater, molecular weight, moisture, heavy metals, and colorimetry for evaluation.
