T/CPCIF 0035-2020 Green Design Product Evaluation Specification 1,4-Butanediol

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 1,4-butanediol (BDO). This standard applies to the evaluation of green design products of 1,4-butanediol produced by methods such as acetylene aldehyde, allyl alcohol, and maleic anhydride. Main technical content: Based on the principle of combining life cycle assessment with indicator evaluation, considering the entire life cycle of 1,4-butanediol 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 and energy 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. According to the characteristics of 1,4-butanediol 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 raw material single consumption, fresh water usage, waste recycling and resource utilization rate, comprehensive energy consumption per unit product, wastewater discharge per unit product, and harmless disposal rate of organic wastewater, purity, moisture, heavy metals, and carbonyl number for evaluation.
