Digital Product Passport (DPP) sets new standards for sustainable clothing manufacturing: co-developed by Working Hasegawa and Chaintope

Working Hasegawa Co., Ltd. (Headquarters: Fukuoka, Japan; President: Shinichi Hasegawa) has partnered with Chaintope Inc. (Headquarters: Fukuoka, Japan; CEO: Hideki Shoda) to initiate a proof-of-concept trial for introducing a Digital Product Passport (DPP) into sukui, a sustainable medical wear brand developed by Working Hasegawa. This initiative aims to address global sustainability standards by enhancing transparency and accountability across the entire product lifecycle within the supply chain, thereby establishing a new framework for sustainable operations.


1. Features of the sukui Brand

Eco-Friendly Hemp Material

sukui primarily uses sustainable industrial hemp from KINGDOM TEXTILE (SHANGHAI) LTD (hereinafter referred to as "KINGDOM") as its main material. This hemp absorbs 13.7 tons of CO2 per hectare during its growth period, effectively reducing atmospheric carbon. Additionally, hemp cultivation requires neither water resources nor pesticides, minimizing environmental impact on agricultural land. It also promotes soil health, supporting the growth of future crops. With such properties, hemp is recognized globally as a "super material" for sustainability, and by utilizing it, sukui champions environmentally friendly production.

Design Emphasizing Circular Economy

sukui products are designed to minimize resource waste and maximize longevity. In collaboration with weavearth, we have designed a manufacturing process that avoids using polyester thread, reducing reliance on petroleum-based materials. To limit material waste, the products are dyed post-sewing. Additionally, sukui has established its own system for repair and cleaning to maintain product quality over time. Used products will also be collected and transformed into compost by leveraging hemp's properties, reducing waste and supporting resource recycling to contribute to a sustainable society.

2. Overview of the DPP System

Transparent Environmental Information Management

The DPP system under development leverages blockchain technology to record CO2 emissions and material traceability across the entire product lifecycle. This allows for reliable environmental data to be accessible to both consumers and business partners, supporting informed choices in sustainable products and companies. sukui’s supply chain extends beyond Japan, including collaboration with Chinese companies such as KINGDOM. Through the DPP system, the aim is to enhance transparency and traceability across the entire international supply chain.

Easy Access through QR Code

Each sukui product is equipped with a label containing a QR code, enabling easy access to its environmental traceability information via scanning. This feature provides consumers with reliable environmental data on the product's lifecycle. At the EXPO in November 2024, a demonstration will showcase this QR code functionality, allowing attendees to experience environmental data based on sample information. The pilot project is planned to continue through February 2025 to evaluate system effectiveness and prepare for commercial deployment. Upon completion, all sukui products will include QR codes.

3. Challenges in the Apparel Industry and the Significance of DPP

Regulatory Compliance and Competitive Advantage

Reducing environmental impact and ensuring supply chain transparency are critical challenges in the apparel industry. The EU will begin mandating DPP in priority sectors, including textiles, starting in 2027, with plans to extend full applicability, including to SMEs, by 2030. In Japan, the Ministry of Economy, Trade, and Industry released the "Environmental Information Disclosure Guidelines" in June 2024, encouraging transparency on greenhouse gas emissions, water usage, and other metrics in textile production. The DPP system thus plays an essential role in enhancing sustainability and strengthening corporate competitiveness by providing transparent environmental data that enables companies to comply with regulations and empowers consumers to make informed choices.

4. EXPO Exhibition Information

DPP system demonstration

A prototype of the DPP system will be showcased at the Blockchain EXPO, held from November 20 to 22, 2024, at Makuhari Messe, Chiba, Japan. This demonstration will allow visitors to scan the QR codes attached to sukui products and view environmental traceability data based on sample information, providing an opportunity to experience how sustainable supply chain management is achieved with the latest system.

5. Regional Initiatives and Collaboration

Blockchain Promotion and DPP System Development with the Support of Iizuka City and Fukuoka Prefecture, Japan

In 2021, Iizuka City in Fukuoka Prefecture, Japan, declared its commitment to becoming a global leader in blockchain, promoting the creation of new industries through academia, industry, and government collaboration. Working Hasegawa and Chaintope's joint development is part of this initiative, backed by support from Iizuka City and Fukuoka Prefecture in Japan, aiming to improve transparency in sustainable supply chains. This project represents a model for promoting sustainability and revitalizing local communities from a regional level, with Iizuka and Fukuoka serving as starting points for building a sustainable future extending from Asia to the world.
