摘要

纺织品和塑料废物是主要的环境挑战。将消费后的聚对苯二甲酸乙二醇酯（PET）瓶回收为家用纺织品回收PET （r-PET）纤维，通过延长材料生命周期提供可持续的解决方案。本研究评估使用r-PET纤维生产家纺的环境和经济可持续性。使用生命周期评估（LCA）和生命周期成本计算（LCC）来探索各种能源和纤维混合物对可持续性结果的影响。本研究的系统边界涵盖了拾荒者收集消费后的PET瓶，出售给当地的破碎厂，并将其转化为PET薄片。然后，Pet薄片被送到挤压设备，转化为用于家用纺织品生产的r-PET纤维。采用从摇篮到大门的方法，采用SimaPro v9.6软件和ReCiPe 2016中点方法量化单色家纺对环境和经济的影响。LCA确定人类致癌毒性（105.36 kg 1,4- dcb）是最大的影响，由化学品的使用和运输驱动，以及低全球变暖（3.43 kg CO 2当量）值。LCC估计总生产成本为28,000美元/吨，其中39.5%归因于染整过程。用太阳能取代重燃料油产生的电力可以减少5 - 6%的全球变暖潜力，50:50的r-PET和原始棉纤维混合显著减少所有影响类别，包括减少14%的用水量。研究结果强调了增加r-PET使用和采用太阳能以提高巴基斯坦纺织部门可持续性的必要性。

Sustainability assessment of home textiles made of recycled PET fibre using life cycle assessment and life cycle costing analyses

Textile and plastic waste are major environmental challenges. Recycling post-consumer polyethylene terephthalate (PET) bottles into recycled PET (r-PET) fibres for home textiles provides sustainable solutions by extending materials life cycles. This study evaluates environmental and economic sustainability dimensions of producing home textiles using r-PET fibre. Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) were used to explore the impacts of various energy sources and fibre blends on sustainability outcomes. The system boundary of this study covers collection of post-consumer PET bottles by scavengers, sale to the local crushing plants and their conversion to PET flakes. Pet flakes are then sent to an extrusion facility for conversion into r-PET fibre which is used in the home textiles production. Using a cradle-to-gate approach, SimaPro v9.6 software and the ReCiPe 2016 midpoint methodology was employed to quantify environmental and economic impacts of one tone home textiles. LCA identified human carcinogenic toxicity (105.36 kg 1,4-DCB) as the highest impact, driven by chemical use and transportation, and low global warming (3.43 kg CO ₂ eq) values. LCC estimated total production cost of $28,000/ton, with 39.5 % attributed to dyeing and finishing processes. Substituting heavy fuel oil-generated electricity with solar energy reduced global warming potential by 5–6 %, and a 50:50 blend of r-PET and virgin cotton fibres significantly decreased all impact categories, including a 14 % reduction in water use. The findings underscore the need for increased r-PET use and adoption of solar energy to improve sustainability in Pakistan's textile sector.

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
