Blockchain-based traceability enhances textile sustainability claims

Why It Matters

The fashion industry faces significant challenges related to environmental and social impact. A transparent and traceable system allows businesses to substantiate their sustainability efforts and empowers consumers to make more informed choices, driving demand for ethical products.

Key Finding

A blockchain-based system, using smart contracts, can reliably track sustainability data throughout the textile supply chain, verifying claims and encouraging a circular economy.

Key Findings

• Smart contracts on Hyperledger Fabric can effectively manage and track sustainability indicators across the textile value chain.
• The developed system provides verifiable traceability, supporting the authenticity of sustainability claims made by industry participants.
• The solution facilitates a move towards a circular economy model by enhancing transparency and accountability.

Research Evidence

Aim: How can smart contracts and web decentralized applications (dApps) be utilized to trace sustainability indicators within the textile and clothing value chain to promote circular economy principles?

Method: Proof of Concept Development

Procedure: Developed a business-to-business solution using Hyperledger Fabric smart contracts for managing the textile value chain, focusing on traceability functionality. This system allows for tracking batches from their origin to the final garment, supporting sustainability claims.

Context: Textile and Clothing Value Chain

Design Principle

Transparency through verifiable data builds trust and drives sustainable practices.

How to Apply

Pilot a blockchain solution for a specific product line, focusing on key sustainability metrics like material origin, water usage, and labor conditions. Gradually expand its application as adoption grows.

Limitations

The effectiveness of this system relies on the accurate and consistent input of data by all participants in the value chain. Scalability and adoption across a fragmented industry remain challenges.

Student Guide (IB Design Technology)

Simple Explanation: Using special computer code (blockchain) can help prove that clothes are made sustainably, making it easier for companies to show they are eco-friendly and for people to trust them.

Why This Matters: This research shows how technology can solve real-world problems like pollution and unfair labor in the fashion industry, making products more ethical.

Critical Thinking: To what extent can consumer demand for verifiable sustainability data drive the adoption of blockchain technology in industries beyond textiles?

IA-Ready Paragraph: This research demonstrates the efficacy of blockchain technology, specifically smart contracts on Hyperledger Fabric, in creating a transparent and verifiable system for tracking sustainability indicators within the textile value chain. This approach offers a robust method for substantiating eco-friendly and ethical claims, thereby fostering greater trust between businesses and consumers and promoting the adoption of circular economy principles.
