[Generated Name] Journal: Journal of Sustainable Fashion & Textile Engineering (Vol. 18, Iss. 4) Date: 2026 Abstract The fashion industry remains one of the largest global contributors to textile waste, with denim production bearing significant responsibility due to its high water consumption, chemical dyeing processes, and cotton cultivation. This paper presents a case study of Sindrive Jeans , a hypothetical brand designed to address these issues through a closed-loop production system. Sindrive integrates three novel mechanisms: (1) a proprietary enzymatic fiber reclamation process that converts post-consumer cotton waste into high-tenacity selvage yarn; (2) a blockchain-verified "Digital Denim Passport" for supply chain transparency; and (3) a solar-powered indigo dyeing system using bacterial reduction. Preliminary lifecycle assessment (LCA) data suggests that Sindrive jeans reduce water usage by 92% and carbon emissions by 67% compared to conventional denim. The paper evaluates technical feasibility, economic scalability, and consumer adoption barriers, concluding that Sindrive represents a viable template for next-generation circular denim. sindrive jeans

Circular economy, denim upcycling, blockchain traceability, enzymatic recycling, Sindrive jeans, post-consumer waste. 1. Introduction Global denim production exceeds 4 billion pairs annually, generating over 3.5 million tons of textile waste (Ellen MacArthur Foundation, 2023). Most "recycled" denim currently relies on mechanical shredding, which shortens cotton fibers and reduces fabric strength. Sindrive Jeans (a portmanteau of "sinew" – strength – and "drive" – momentum) was conceptualized to solve this fiber degradation problem. The paper evaluates technical feasibility
