1948422 (Kim). The clothing industry is one of the most polluting industries in the world, producing 1.2 billion tons of carbon emissions per year, with a truckload of clothing discarded globally every second. Diverting high volume cotton textile waste is a promising route to minimize pollution and energy and water-intensive production of new clothing. Green chemistry strategies to breakdown natural fabric waste into feedstocks for reconstituted fibers has tremendous potential to move towards zero waste economies based on cradle to cradle design strategies. About one third of the cotton muslin used at educational fashion institutions (e.g. FIT) in the fashion design sewing, draping and pattern making classes, goes to waste. The cotton muslin used in the classrooms is undyed and unbleached, making it an excellent resource for developing green methods to breakdown natural fibers to cellulosic feedstock. This project seeks to elucidate the chemistry and surface science crucial for optimizing an environmentally-benign degradation process to reconstitute muslin waste to produce precursor materials for textiles. The research objectives of the work include: 1) Optimization of an environmentally-benign method for the regeneration of cellulosic feedstock from cotton waste. 2) Macro to nanoscale characterization of degradation/regeneration mechanisms to identify new opportunities for reduction of the textile waste stream. This project is a collaborative opportunity for student-driven realization of circular economy and sustainability leadership at the intersection of science and design. It also provides a conduit for project-based STEM education as a tool to address pressing global challenge. Successful outcomes of the project will provide a method for cotton muslin waste green chemistry degradation procedures. Investigation of environmentally-benign wet chemistry routes to muslin breakdown will be coupled with a suite of chemical analysis tools, including spectroscopy and microscopy, to understand the interaction between process chemistry and cotton molecular structure. The research will focus on expanding the utility of the chemical approach beyond muslin waste to cellulosic textiles and dyed fabrics in general. This work could highly impact the development of accessible models for circular economy materials and offers a conduit for ecological design and systems thinking in a STEM framework. Non- traditional science students from FIT (especially women and minorities) will perform research activities at Stony Brook University through the Institute for STEM Education (I-STEM), the Women in Science and Engineering (WISE) program, Undergraduate Research & Creative Activities (URECA), Research Experiences for Undergraduates (REU) programs, and the Center for Inclusive Education (CIE) as well as at FIT. Undergraduate students from both Stony Brook University and FIT will receive academic credit, either for independent research or in the context of project work in one of the interdisciplinary courses or programs (e.g. Designing with Emerging Materials, The True Cost: Product Life Cycle Assessment).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

1948422（金）。服装行业是世界上污染最严重的行业之一，每年产生12亿吨碳排放，全球每秒就有一卡车的衣服被丢弃。转移大量棉纺织废料是最大限度减少污染以及新服装生产过程中能源和水密集型生产的一条有前途的途径。将天然织物废物分解为再生纤维原料的绿色化学策略具有巨大的潜力，可以实现基于从摇篮到摇篮设计策略的零废物经济。时尚教育机构（例如 FIT）在时装设计缝纫、立体裁剪和制版课程中使用的棉布大约有三分之一被浪费了。教室中使用的棉布未经染色和漂白，使其成为开发将天然纤维分解为纤维素原料的绿色方法的极好资源。该项目旨在阐明对于优化环境友好的降解过程至关重要的化学和表面科学，以重组平纹细布废物以生产纺织品前体材料。该工作的研究目标包括：1）优化从棉花废料中再生纤维素原料的环境友好方法。 2) 降解/再生机制的宏观到纳米尺度表征，以确定减少纺织废物流的新机会。该项目为学生在科学与设计交叉领域推动循环经济和可持续发展领导力的实现提供了一个合作机会。它还为基于项目的 STEM 教育提供了渠道，作为应对紧迫的全球挑战的工具。该项目的成功成果将为棉纱废料的绿色化学降解程序提供一种方法。对平纹细布分解的环境友好湿化学途径的研究将与一套化学分析工具（包括光谱学和显微镜）相结合，以了解工艺化学与棉花分子结构之间的相互作用。该研究的重点是将化学方法的用途从平纹细布废料扩展到一般的纤维素纺织品和染色织物。这项工作可能会对循环经济材料的可访问模型的开发产生重大影响，并为 STEM 框架中的生态设计和系统思维提供渠道。 FIT 的非传统理科学生（尤其是女性和少数族裔）将通过 STEM 教育研究所 (I-STEM)、女性科学与工程 (WISE) 计划、本科生研究与创意活动 (URECA)、本科生研究经验 (REU) 计划以及全纳教育中心 (CIE) 以及 FIT 在石溪大学开展研究活动。来自石溪大学和 FIT 的本科生将获得学分，无论是独立研究还是跨学科课程或项目之一的项目工作（例如，新兴材料设计、真实成本：产品生命周期评估）。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
