Despite the growing attention toward negative environmental impacts generated by the textile industry, companies face challenges in achieving sustainable and circular economy (CE) transition. The literature has so far lacked a systematic effort to analyze how textile companies can insert CE elements in their new product development process (NPD), especially regarding the proposition of methodologies that can better assist the companies in this regard. This study aims to identify good green innovation and CE practices in NPD adopted by textile companies and propose a methodology from Design Thinking (DT) to insert circular thinking in NPD. To that end, we conducted the research in two steps: (i) narrative bibliographic review and (ii) field research. The bibliographic review was conducted in the "Web of Science", "Scopus", and "Scielo" databases. The field research was executed with four textile companies. Our results show that companies tend to consider socio-environmental aspects at different stages of the development of new products. However, there is opportunities for improvement, especially through the use of ideas from DT. The proposed methodology is composed of two main cycles: the design cycle (DT stages) and the consumption cycle (subsequent stages). It encompasses the five main stages of the DT and the three macro phases of NPD of the textile industry. The ideas coming from the DT, especially creativity, focus on the user and stakeholder integration, assist in the development of innovative and circular solutions. The methodology presents how companies can work on reuse, recycling, and manufacturing issues, so that CE occurs. In the end, we evaluated, together with experts, the applicability of the proposed use of ideas of DT in practical cases. The research advances the discussions on NPD in the textile sector, especially on its potential to contribute to the transition to CE. It explores how DT assists in inserting circular thinking into the NPD and presents alternatives for companies to develop circular products and insert green innovations in their NPD.

Many studies demonstrate the potential contribution of the Product-Service System (PSS) to the development of sustainable management practices and Circular Economy (CE). However, companies face challenges when implementing PSS, and few studies examine how the manufacturing industry can develop sustainable offerings by adopting product-oriented PSS, especially in the agricultural machinery industry. Thus, we investigated how this industry perceives environmental sustainability and product-oriented PSS, and we identified practices that can be implemented to qualify the life cycle management of their products. Based on that, we proposed a conceptual model for implementing product-oriented PSS in the agricultural machinery sector. An exploratory research was carried out in two steps: a systematic literature review complemented by multiple case studies. We list the possibilities of product-oriented PSS services that can be offered for traditional industries to guide their business towards sustainable practices. In parallel, we have identified good practices and benefits of adopting product-oriented PSS. Subsequently, we conducted a diagnosis on sustainability and product-oriented PSS in agricultural machinery companies. Although companies already offer some services to customers, our results show ample opportunities for improvement, especially to offer product-oriented PSS considering socio-environmental issues. In this sense, the conceptual model proposed allows industries to expand their understanding and adherence to product-oriented PSS. As contributions, we demonstrate how the agricultural machinery industry can develop sustainable practices and promote CE through product-oriented PSS implementation. [ABSTRACT FROM AUTHOR]
