This is a sustainable design-based article reviewing traditional scouring within the processing of Irish sheep wool, identifying obstacles and proposing a conceptual solution, titled ‘Glan Wool Scouring Equipment’, also referred to as Glan throughout this article. Glan is a conceptual design solution aimed at addressing these specific industry challenges by providing a more efficient manual scouring process. This design is informed by extensive research conducted as part of this study, which explores the current landscape of wool processing, the role of tradition in scouring and the broader environmental and economic implications of the practice. Wool is biodegradable and, through localization, we can support rural economies while reducing transport-related emissions. However, wool is often treated as a secondary or waste by-product of the agricultural industry, creating weak financial incentives for farmers to collect and sell it. Recent reports in Ireland note prices low enough to harm farm incomes. ‘Scouring’ is the removal of impurities from the fleece after the animal is sheared and before further processing, a labour- and resource-intensive practice. The impact of scouring on the productivity and environmental footprint of the industry was analysed during this research, along with the contemporary challenges faced. Promoting traditional scouring helps preserve cultural heritage and support environmentally and ethically responsible textile production. Designing for low waste and prioritizing low-impact materials are widely recognized as core circular design strategies. In this article, a novel concept which was developed in response to these industry needs is presented. This equipment, Glan (meaning ‘clean’ in the Irish language), is designed to improve the efficiency, sustainability and user experience of the traditional scouring process to boost productivity, profitability and inclusivity, increasing awareness and broader adoption. By integrating innovative solutions into traditional frameworks, this research demonstrates how heritage is balanced with progress to support global movements towards sustainable fashion and textiles. By using resources derived from tradition to drive innovation we can progress towards an economically and sustainably successful future.
