Nippon Yusen Kaisha (NYK) Reintroduces Ship Recycling in Japan: A Move Towards Sustainable Steel Production
In a strategic move to bring ship recycling back to its shores, Japan’s leading shipping company, Nippon Yusen Kaisha (NYK), has partnered with Oono Development to commercialize ship and offshore structure dismantling. This venture is poised to play a pivotal role in the country’s steel industry transformation, contributing to carbon neutrality goals and a more sustainable shipbuilding process. The collaboration also aims to address longstanding challenges in the recycling of steel, marking an important step in Japan’s efforts toward greener industries.
A Collaborative Step Towards Sustainable Ship Recycling
NYK, a major player in the global shipping industry, recently signed a memorandum of understanding (MOU) with Oono Development, a fellow Japanese firm specializing in environmentally-conscious businesses. The MOU signals their intention to establish a commercial framework that enables the dismantling of ships and large offshore structures within Japan. Once dismantled, these structures will be recycled into steel scrap and other reusable materials.
The recycling of ships is not only about disposing of old vessels but also about reclaiming high-quality steel, which makes up the bulk of a ship’s structure. More than 90% of medium and large vessels are recycled into construction materials, recycled steel, or other usable products after their decommissioning. This initiative is set to become increasingly relevant as Japan transitions to new methods of steel production, with a focus on sustainability and environmental responsibility.
The Shift to Electric Arc Furnaces and Steel Impurities
Central to the revival of ship recycling in Japan is the country’s shift toward using electric arc furnaces (EAF) in steel production. Unlike traditional blast furnaces that rely heavily on iron ore and coke, electric arc furnaces recycle steel scrap, making them far more energy-efficient and environmentally friendly. This shift is crucial as Japan pushes toward its carbon neutrality objectives. However, one of the challenges faced by EAF technology is the impurities found in recycled steel scrap, which can degrade the quality of the steel produced.
This is where shipbreaking comes into play. Ships are built with high-quality steel that can be recycled with relatively low levels of impurities. By dismantling ships domestically, Japan has the opportunity to produce steel that meets stringent quality standards while minimizing the environmental impact of importing raw materials. High-quality steel scrap is increasingly valuable in industries aiming for low impurity content in their final products, including shipbuilding and construction.
NYK has acknowledged that achieving sustainable recycling practices requires careful consideration of safety, environmental impact, and efficiency in ship dismantling operations. By leveraging advanced recycling methods and adhering to environmental regulations, Japan could create a model for responsible shipbreaking that could be emulated by other nations in the region.
The Lost Opportunity of 1.5 Million Tonnes of Scrap Steel
Japan’s recent push to reintroduce ship recycling is a response to a missed opportunity highlighted by NGO Shipbreaking Platform. In 2023, the advocacy group estimated that the Japanese steel sector lost the chance to recycle approximately 1.5 million tonnes of scrap steel from end-of-life ships owned by Japanese companies. This significant volume of high-quality steel was instead processed in countries like Bangladesh, Pakistan, India, and Turkey—nations that have long dominated the global ship recycling market.
While Japan has not been an active player in ship recycling for many years, the demand for shipbreaking is expected to skyrocket over the next decade. According to expert forecasts, the number of ships reaching the end of their operational lives will quadruple, necessitating the development of more robust recycling solutions. With this in mind, NYK’s partnership with Oono Development is seen as a crucial step in reclaiming Japan’s leadership in the sector, while contributing to broader sustainability goals.
NGO Shipbreaking Platform, which advocates for cleaner and safer recycling practices, emphasized that ship recycling represents a promising solution for Japan’s carbon neutrality objectives. By capitalizing on the high-quality scrap steel found in Japanese vessels, the country could address both environmental and economic challenges. The organization noted, however, that as of now, no significant ship dismantling operations for ocean-going vessels are currently underway in Japan.
Oono Development: A Key Partner in the Project
Ehime-based Oono Development, NYK’s partner in this endeavor, plays a critical role in Japan’s environmental sector, with expertise spanning demolition, waste disposal, and recycling. The company owns one of the largest dry docks in Japan, located in Chita City, Aichi Prefecture. This dry dock has the capacity to dismantle two large ships simultaneously, making it an ideal location for the country’s ship recycling operations.
Oono’s dry dock is the only recycling facility of its kind in Japan, equipped to handle large vessels, a necessary feature for efficient and safe shipbreaking. NYK highlighted the strategic importance of this dry dock in its recycling plans, citing its ability to process ships on a large scale while adhering to stringent environmental and safety standards.
By utilizing Oono Development’s resources, NYK aims to establish a commercially viable ship recycling business that not only contributes to the domestic steel industry but also aligns with global standards for sustainability and worker safety. This partnership positions Japan as a potential leader in environmentally friendly shipbreaking, an industry often criticized for its dangerous and polluting practices in other parts of the world.
Global Competition in Ship Recycling
Despite Japan’s ambitions to revitalize its ship recycling industry, it faces stiff competition from established players such as Bangladesh, Pakistan, India, and Turkey. These countries have long been the dominant forces in shipbreaking, particularly after China closed its market to foreign-flagged ships in 2019. The cost-effectiveness of shipbreaking in these regions, driven largely by lower labor costs and less stringent environmental regulations, has made them attractive destinations for shipowners looking to scrap their vessels.
However, other nations have recently shown interest in entering the sector. Countries like Egypt, Brazil, and Bahrain are positioning themselves as emerging players in ship recycling, anticipating a surge in demand by 2028. Japan’s decision to invest in domestic ship recycling comes at a time when the industry is poised for rapid growth, with projections indicating a significant increase in the number of ships reaching the end of their service lives.
Towards a Circular Economy in Shipbuilding
One of the long-term goals of NYK’s ship recycling initiative is to create a circular economy in shipbuilding. While electric arc furnaces are not yet producing the shipbuilding-grade steel plates required for new vessel construction, the recycled steel from scrapped ships could potentially be reborn as thick plates for shipyards. If successful, this process would allow for the creation of completely circular newbuilds—ships made from the recycled steel of their predecessors.
This vision aligns with Japan’s broader commitment to sustainability and reducing the environmental footprint of its industries. By integrating ship recycling into the domestic steel production process, Japan can reduce its reliance on imported raw materials, lower greenhouse gas emissions, and contribute to the development of a more circular economy.
Conclusion
The partnership between NYK and Oono Development marks a significant step in Japan’s efforts to reclaim its position in the global ship recycling industry. By focusing on the sustainable dismantling of ships and the recycling of high-quality steel, Japan has the potential to contribute to its carbon neutrality objectives while addressing the challenges of steel impurities in the electric arc furnace era. As the global demand for ship recycling grows, Japan’s initiative may serve as a model for other nations looking to balance economic growth with environmental responsibility.
