T/CPCIF 0039-2020 Green Design Product Evaluation Specification for Polystyrene Resin

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 made from polystyrene resin. This standard applies to the evaluation of green design products made from polystyrene resin, including general-purpose products, expandable products, and other models, which shall be evaluated in accordance with the indicators specified in this standard. Main technical content: Based on the principle of combining life cycle assessment with indicator evaluation, this standard considers the entire life cycle of polystyrene products, from product design, raw material acquisition, product production, product use, post-disposal recycling, and comprehensive utilization of industrial wastewater and solid waste, to conduct in-depth analysis of resource and energy consumption, ecological environment, and human health factors at each stage. Selected indicators that can be evaluated at different stages are used to form an evaluation index system. Based on the characteristics of polystyrene products and production processes, and taking into account the high social attention and the types of environmental impacts explicitly required by national laws or policies, key resource attributes, energy attributes, environmental attributes, and product attributes are selected for evaluation. This technical specification selects indicators such as raw material unit 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 content, heavy metals, and carbonyl number for evaluation.
