The broader impact of this SBIR Phase I project is to remediate the 17 million tons of textile waste that ends up in landfills annually. Working within the existing economic drivers of the clothing industry, this project aims to deploy technology that can profitably transition the USA away from a wasteful zero-sum linear raw materials model into a resilient local and sustainable circular economy. This project will enable local communities, urban and rural alike, to create economic value (raw materials and jobs) out of textile waste, with a drastic reduction in carbon footprint and greenhouse gas emissions compared to business as usual. This project will develop technology that has an impact on the security and sustainability of the US textile raw materials marketplace, by enabling a re-shoring of an industry in a distributed way that can affect every single American through their clothing purchasing options. If successful, the US could lead the world into a new era of a truly sustainable circular economy for fashion.This project aims to advance knowledge and develop the core technologies required for widespread adoption and commercialization of cellulosic textile recycling within the American textile manufacturing industry. By leveraging core competencies and innovative models for polymer science and continuous process design, this project will develop a non-destructive extractive process that will locally and domestically convert end-of-life textile waste into high-value cellulosic circular economy feedstocks of equal or greater quality to virgin material at kilogram scale. As part of this project, the focus will be on extracting cellulose from mixed material textile waste that contain other contaminant components that often hinder its recycling. This approach involves innovative mixtures of green chemistry that enable the rapid extraction of cotton, the spinning of novel fibres, and the efficient recovery of the process chemicals. This project will optimise and further develop this core technology and conduct the prototyping and engineering design required for reproducible cellulosic material (cotton) extraction from clothing waste and its demonstration at multi-kg scale.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.

该SBIR I期项目的更广泛的影响是补救每年在垃圾填埋场中最终出现的1700万吨纺织废物。该项目在服装行业的现有经济驱动因素中工作，旨在部署能够从浪费的零和线性原材料模型转变为富有弹性的本地且可持续的循环经济的技术。该项目将使当地社区（城市和农村）能够从纺织废物中创造经济价值（原材料和工作），与往常相比，碳足迹和温室气体排放量的急剧减少。该项目将通过以分布式方式重新发挥行业来开发对美国纺织原材料市场的安全性和可持续性产生影响的技术，从而通过其服装购买选择来影响每个美国人。如果成功的话，美国可能会带领世界进入时尚真正可持续的循环经济的新时代。该项目旨在促进知识并开发广泛采用和商业化纤维素纺织品回收所需的核心技术。通过利用核心能力和创新模型进行聚合物科学和连续过程设计，该项目将开发出一个非破坏性的提取过程，该过程将在本地和国内将寿命末期纺织废物转换为高价值的纤维素圆形圆形经济体，该纤维素圆形经济体的质量相等或更大的质量以公斤量表为单位。作为该项目的一部分，重点将放在从混合材料纺织品废物中提取纤维素，这些废物包含其他污染物成分，通常会阻碍其回收。这种方法涉及绿色化学的创新混合物，可快速提取棉，新型纤维的旋转以及工艺化学物质的有效恢复。该项目将优化并进一步开发该核心技术，并进行原型制作和工程设计，以从服装废物中提取可再现的纤维素材料（棉花）及其在多兆格量表上进行演示。该奖项反映了NSF的法定任务，并被认为是通过该基金会的知识分子功能和广泛影响的评估来评估Criteria的智力优点和广泛的支持。
