Introduction, Rising Demand for Smarter Metal Recycling
Japan’s metal recycling sector has entered a moment of rapid transformation. Labor shortages, growing environmental demands, and the urgent need for higher-quality scrap materials have pushed the industry toward digital solutions. Against this backdrop, Mitsui & Co. has made a decisive move. The company announced an investment in Eversteel, a University of Tokyo–born startup that uses advanced artificial intelligence to detect impurities in iron scrap and automate classification. This partnership signals a major technological pivot, not only for Japan’s domestic recycling workflow but also for the global steel ecosystem that relies heavily on scrap as a sustainable resource.
AI-Driven Scrap Sorting, A Detailed the Original
Mitsui’s Strategic Entry Into AI Recycling
Mitsui & Co. revealed that it will invest several hundred million usd in Eversteel, although the precise amount remains undisclosed. The objective is clear, strengthening Mitsui’s technological capabilities in steel recycling and supporting a fast-growing startup with a powerful AI tool.
Eversteel’s Academic Origins and Technical Focus
Founded in 2021 and emerging directly from the University of Tokyo, Eversteel develops an AI-enhanced system capable of analyzing scrap metal as it arrives at the factory. Using camera-based detection, the system identifies impurities and automatically sorts materials by type and grade, a process traditionally dependent on human visual inspection.
Addressing Long-Standing Manual Inspection Challenges
Human checking has long been considered the bottleneck of scrap processing. Workers visually inspect scrap as trucks unload material, which is labor-intensive, inconsistent, and prone to human error. Eversteel’s AI promises more accurate detections and faster throughput, solving both manpower shortages and quality reliability issues.
Mitsui’s Partnership and the Path to Full Investment
The collaboration between Mitsui and Eversteel began in 2023, when they entered a comprehensive business partnership. Since then, Mitsui’s subsidiary, MMK Metals, has introduced Eversteel’s system to customers, leading to strong adoption results. Encouraged by these outcomes, Mitsui decided to proceed with direct investment, expected to be completed within the fiscal year ending March 2026.
Focus on Domestic Market, But Eye on Global Scaling
Eversteel’s current sales efforts primarily target Japanese steel manufacturers. Yet plans for overseas expansion are already in motion. Mitsui is considering introducing Eversteel’s AI system to foreign scrap firms in which it holds stakes, leveraging its global trade network.
A Vision of Global Deployment
During a press conference in Tokyo, Tatsuo Sato, General Manager of Mitsui’s Steel Raw Materials Division, emphasized that the system has “significant room to expand overseas,” hinting at a long-term strategy to make AI scrap sorting an international standard.

AI as the New Backbone of Scrap and Steel Quality Control
AI-supported classification represents more than a technological upgrade. It signals the beginning of automated quality assurance in one of the world’s most resource-intensive industries. Scrap is now as important as virgin iron ore. Every percentage point of impurity removed translates to energy savings, lower emissions, and improved steel consistency.
Why Mitsui’s Investment Is Timely
Mitsui is a global powerhouse whose decisions often shape sector-wide norms. Investing now, at a moment when AI adoption in heavy industry is still in its early stages, gives the company a commanding first-mover advantage. If Eversteel’s technology becomes widely accepted, Mitsui won’t simply be a shareholder; it will control a gatekeeper technology essential to future recycling.
Eversteel’s Academic DNA as a Competitive Edge
Startups emerging from major universities often bring deep theoretical knowledge into practical fields. Eversteel’s foundation in academic research grants it access to cutting-edge algorithms, faster prototyping cycles, and direct links to the scientific community. These are enormous advantages in a market where incremental accuracy improvements can reconfigure the entire logistics chain.
Targeting the Steel Electric Furnace Ecosystem
Electric arc furnace manufacturers rely heavily on scrap quality. Subpar scrap leads to higher electricity consumption, unnecessary refining steps, and structural inconsistencies in the final steel. By optimizing input quality at the earliest stage, Eversteel has positioned itself at a critical choke point of the supply chain.
Labor Shortages Turn AI Into a Necessity
Recycling sites worldwide suffer from chronic labor shortages, especially in inspection roles that require experience but yield strenuous work conditions. AI does not replace workers but amplifies their ability to supervise multiple operations simultaneously. Efficiency becomes scalable, not dependent on individual skills.
The Global Ambition Behind Mitsui’s Comments
When Mitsui executives state that the system has “vast overseas potential,” they point to more than sales opportunities. Mitsui owns or has stakes in scrap companies across Asia, North America, and Europe. The company can rapidly integrate AI across these networks, creating a global standard for impurity detection that competitors will be pressured to follow.
Economic Incentives Align With Environmental Responsibility
The world is shifting toward decarbonized steel. Higher-quality scrap reduces reliance on blast furnaces and lowers emissions. This positions Eversteel’s technology at the heart of the green steel revolution, where ESG commitments are just as important as profitability.
From Domestic Pilot to Worldwide Standard
Eversteel’s early traction within Japan demonstrates strong product-market fit. Once the system proves itself in multiple overseas mills, Mitsui can offer an end-to-end AI quality control solution. This would transform the company into a central infrastructure provider in scrap logistics.
🔍 Fact Checker Results
✅ Mitsui & Co. confirmed its investment in Eversteel, though the amount remains undisclosed.
✅ Eversteel was founded in 2021 and develops AI systems for impurity detection and scrap sorting.
❌ There is no confirmation that the system is already widely deployed overseas; expansion is still under consideration.
📊 Prediction
AI-based scrap sorting will expand rapidly through Mitsui’s global channels.
Electric furnace manufacturers will increasingly mandate automated impurity detection to stabilize output quality.
Within five years, AI-driven scrap grading may evolve into an international benchmark, reshaping trade flows and metal recycling economics.
