Chiyoda Ute and Senba's Strategic Alliance for Circular Economy

Chiyoda Ute Corporation, headquartered in Mie Prefecture and led by President Yoshihisa Hirata, has officially announced a partnership with Senba Co., Ltd., a Tokyo-based company chaired by Jun Odagiri, effective July 1, 2025. This collaboration aims to enhance sustainability practices within the construction industry, particularly through the recycling of gypsum boards.

Partnership Overview

The core of this partnership will see Chiyoda Ute's innovative product, the "Chiyoda Circular Gypsum Board," made from 100% recycled gypsum, being actively utilized at Senba’s construction sites. This effort includes not only the use of the circular board but also a commitment from Senba to provide used gypsum boards from their sites for recycling. Together, they aim to strengthen systems that facilitate the reprocessing of materials, pushing the boundaries of green building practices in the construction sector.

Addressing Industry Challenges

Gypsum boards, while widely used for interior finishes in residential and commercial buildings, pose significant waste management challenges. When buildings are demolished or renovated, a substantial amount of waste is generated, much of which ends up in landfills. The problem is exacerbated by a dwindling supply of domestic gypsum resources, with Japan importing over 2 million tons of gypsum annually. This pressing issue highlights the need for effective reuse strategies within the industry.

Chiyoda Ute has long been dedicated to promoting a “horizontal recycling” model, aiming for the collection, reprocessing, and reintegration of waste gypsum back into usable building materials. The recent alliance with Senba marks a significant step forward in establishing a more efficient circular economy model in the construction sector.

Key Initiatives Following Partnership

1. Promoting Recycled Products: By incorporating the Chiyoda Circular Gypsum Board into Senba's construction projects, both companies seek to accelerate the acceptance and utilization of recycled products, thereby creating tangible outcomes toward resource circulation.

2. Strengthening the Recycling Supply Chain: Senba will be instrumental in providing used gypsum boards, thereby bolstering the supply chain for recycled materials. This cooperative effort will ensure a stable supply of sustainable products for future projects.

3. Creating Broader Industry Impact: By sharing the results of this partnership, the two companies will work to raise public awareness about gypsum board recycling and encourage a paradigm shift in industry attitudes towards adopting circular economic practices.

Future Prospects

Chiyoda Ute aims to deepen its collaboration with Senba not only to enhance recycling efforts but also to contribute significantly to the establishment of a circular economy within the construction sector. This commitment is part of their overarching goal to lead the industry towards a more sustainable future through innovation and transformation of distribution processes.

Previous Initiatives

A brief on past initiatives taken by both companies showcases a history of innovative practices, including the industry's first joint demonstration project focused on horizontal recycling of gypsum boards.

Chiyoda Ute's mission aligns closely with its foundational philosophy, declared in their VISION: "We provide the most environmentally friendly gypsum board and construction solutions that are fully recyclable." The company prioritizes building a sustainable society through unique initiatives like "CHIYODA VISION ZERO."
