Abstract:
The contradiction between the rapid textile expansion and intensive energy consumption, highly environmental pollution calls for the adoption of cleaner production (CP). However, current evaluation system mainly targeted on CP at production stage, guidance and support on the life cycle assessment is still in its infancy. Meanwhile few studies brought the combination of water conservation and carbon reduction into considerations. This study compared the existing CP evaluation systems including guidelines for the whole industry, standards for textile industry and indicators for the dyeing and finishing sector by quantifying the differences of indicator score compositions. Comparisons analysis from six aspects suggested that all the evaluation systems had relevant indicators regarding \"pollutant emissions\". \"Management\", \"process equipment and techniques\" and \"resource and energy consumption\" have also been well concerned while \"product characteristic\" seemed to be overlooked at current stage. From the perspective of whole life cycle, the key of textile processing is the \"printing and dyeing\" (44.23 %) followed by \"fabric manufacturing\"(28.85 %) and setting (15.38 %). With regards to the environmental impacts, resources depletion gained the highest attention since their indicator scores reached up to 25.71 %, 18.47 % and 20.62 % for EMAS, ERG 2018 and HJ-1852006. Cleaner production awareness and social impact also played significant roles in ISO 14031:2021 and WMG. Subsequently, a set of new comprehensive CP evaluation indicator system was established, including 3 scopes and 7 goals. The newly-built indicator system incorporated with life cycle perspectives gave a powerful tool to measure the CP level in textile industry and of CP will benefit from water reuse and energy utilization with high efficiency.
摘要:
快速的纺织扩张与密集的能源消耗之间的矛盾,高度环境污染要求采用清洁生产(CP)。然而,目前的评价体系主要针对生产阶段的CP,对生命周期评估的指导和支持仍处于起步阶段。同时,很少有研究将节水和碳减排相结合。本研究比较了现有的CP评估系统,包括整个行业的指南,从六个方面的比较分析表明,所有评估体系都具有“污染物排放量”的相关指标。\"管理\",“工艺设备和技术”和“资源和能源消耗”也受到了广泛关注,而“产品特性”在现阶段似乎被忽视了。从整个生命周期的角度来看,纺织加工的关键是“印染”(44.23%),其次是“织物制造”(28.85%)和凝固(15.38%)。关于环境影响,资源枯竭获得了最高的关注,因为他们的指标得分高达25.71%,EMAS的18.47%和20.62%,ERG2018和HJ-1852006。清洁生产意识和社会影响在ISO14031:2021和WMG中也发挥了重要作用。随后,建立了一套新的CP综合评价指标体系,包括3个范围和7个目标。与生命周期观点相结合的新建立的指标体系为衡量纺织工业的CP水平提供了强大的工具,CP将受益于高效的水再利用和能源利用。
