Semiconductor security gets a boost from Japan's first SF6 recycling plant.

Semiconductor security gets a boost from Japan's first SF6 recycling plant. China may dominate global fluorite output, but Japan's new recycling plant offers a homegrown solution to a critical semiconductor supply risk. A large-scale plant for producing fluorite, completed by Sumitomo Densetsu and Professor Shinji Yasui of Nagoya Institute of Technology (center), in Nagoya. (Courtesy of Sumitomo Densetsu) このページを 日本語 で読む Sumitomo Densetsu and Nagoya Institute of Technology Professor Shinji Yasui have completed a plant that produces high-purity fluorite, an essential mineral for semiconductor manufacturing. What makes this facility unique is its ability to recover sulfur hexafluoride (SF6), a fluorinated gas used as an insulator in electrical equipment, and convert it into fluorite, creating a new domestic production route. This project represents the world's first commercially viable process of its kind, reducing dependency on imported fluorite and improving Japan's supply chain reliability. Fluorite is the main raw material used to produce fluorine. Fluorine-based chemicals made from it are used in products such as air conditioners and are indispensable to semiconductor manufacturing. Because fluorite is essential to high-tech manufacturing, Japan has designated it a "specified critical product" under its Economic Security Promotion Act. Its supply stability is directly linked to national economic security. Yet supply risks persist. In 2025, China produced about 60% of global natural fluorite output. When Mexico and Mongolia are added, the three countries together account for roughly 90%. Recycling SF6 into a critical mineral. Japan's Cabinet Office has warned that any disruption in fluorite supplies could halt nearly all semiconductor production, thereby threatening Japan's economic security. The office notes that finding substitutes is difficult and explains that Japan imports all of its domestic needs, making the country excessively dependent on overseas sources. Fluorine also creates a potent greenhouse effect when released into the atmosphere. At present, some waste from fluorine-based chemical processes is landfilled as sludge containing low concentrations of fluorite. This practice has prompted efforts to recover fluorine more efficiently, extract fluorite, and reuse it, an approach seen as advancing both climate goals and economic security. The newly completed plant recovers SF6, a fluorine compound used as an insulating gas in high-voltage power equipment, and converts it into fluorite with a purity exceeding 99%. In the process, a gas mixture of SF6 and hydrogen is heated to 1,000-1,200 degrees Celsius. It then passes through a 200-degree low-temperature stabilization furnace packed with calcium carbonate, where fluorite forms. The system can produce about 3.2 tons of fluorite a year from two tons of SF6. A world-first plant nears commercial use. A plant capable of producing fluorite from SF6 at a practical-use level marks the first of its kind in the world. The team will move it to Takaoka, Toyama Prefecture, in April, to a Sumitomo Densetsu partner company. After trial runs, stakeholders expect full-scale operations to begin around July. According to Japan's Ministry of Economy, Trade and Industry, the amount of SF6 held domestically is estimated at 9,500 tons. "Fluorine compounds that have been disposed of as waste are turned into a resource through the production of fluorite," Professor Yasui said. "This can help realize a circular economy by creating a cycle from resource production to consumption and recovery, and it will also lead to a reduction in greenhouse gases." Yasui began developing the plant about 20 years ago while working at the Central Research Institute of Electric Power Industry, though few paid attention to the project at the time. Sumitomo Densetsu later partnered with Yasui, concluding that they could achieve dual benefits: higher corporate value and additional earnings from recovering and reusing SF6. Remaining hurdles. One challenge to commercialization, however, is the low purchase price of fluorite. Sumitomo Densetsu aims to recoup its investment by tapping Japan's J-Credit Scheme, under which companies and local governments can buy government-certified reductions in carbon dioxide emissions. Daikin Industries also reuses fluorite recovered during the disposal of fluorochemical products. AGC likewise reuses recovered fluorite, but has focused on raising its purity, producing what it calls "recycled fluorite" from wastewater at plants that handle fluorine. AGC has also boosted the value of its products by obtaining third-party certification for the share of recycled fluorite used in its fluorine-based products. Ensuring the economic security benefits of domestically produced fluorite will require coordination among a broad range of stakeholders, including the government.

Fiber Optics Industry Leaders Announce Collaboration to Define a New Multicore Fiber Design Optimized for AI Data Center Campuses

Fiber optics industry leaders announce collaboration to define a new multicore fiber design optimized for AI Data Center campuses. March 12, 2026 SPARTANBURG, S.C. March 11, 2026 | America Fujikura Ltd. (AFL), Corning Incorporated, Sumitomo Electric Industries, Ltd., and TeraHop PTE. LTD., today announced a collaboration to develop a new Multi-Source Agreement (MSA) called the "SDM4 MCF MSA," that outlines the critical four-core multicore fiber design, performance, and interoperability requirements for passive optical connections in data center applications. As AI network scale-out creates an unprecedented demand for higher density optical infrastructure and traditional single-core fiber solutions approach their practical limitations, the industry, including hyperscalers, is turning to new technologies like multicore fiber that can deliver more capacity and connectivity within the same physical infrastructure. This collaboration aims to define the operating procedures, scope, technical requirements, and other terms of the SDM4 MCF MSA to facilitate multicore fiber adoption across diverse environments, such as intra-campus networks and other short-reach interconnect applications operating in the O-band. It can also serve as a foundation and help accelerate development of new global technology and information standards in standardization bodies, including the International Telecommunication Union Telecommunication Standardization Sector (ITU-T), International Electrotechnical Commission (IEC), and Institute of Electrical and Electronics Engineers (IEEE), associated with multicore fiber solutions. Members of the MSA intend to finalize and publicly release the initial SDM4 MCF Specification in the coming months in concert with leading hyperscaler(s) support. Additional MSA members will be welcomed after the initial release to support ongoing multicore fiber ecosystem development and market adoption. MSA: An industry-defined, multi-vendor agreement that establishes common technical and interoperability requirements - typically documented in an MSA specification - so that products and components from different suppliers can work together. AI scale-out: The horizontal expansion of AI infrastructure by adding more servers, racks, or GPUs so workloads can run across larger multi-node clusters, increasing demands on network interconnects. O-band: The 'original' optical transmission band, typically 1260-1360 nm and centered around 1310 nm, commonly used for short-reach optical links because chromatic dispersion is low near this wavelength.

Highland port to expand in multi-million-pound upgrade plan

Highland port to expand in multi-million-pound upgrade plan. PLANS to expand a port in the Highlands have been proposed as part of a multi-million pound investment into the site. Mitsui, a Japanese trading firm, bought the Port of Nigg and its fabrication arm from Global Energy for an undisclosed sum in July this year. The firm has announced plans to extend the quayside of the green freeport out into the Cromarty Firth, with the extension proposed to be 20m (66ft) of water depth. The proposed expansion would mean the Port of Nigg would be able to take larger ships and barges for loading offshore wind turbines. The site, located in Easter Ross on the Cromarty Firth, is seen as vital to the expansion of offshore wind and its supply chain and is one of Scotland's two "green free ports". It comes after Sumitomo Electric, another Japanese company, unveiled its plans to invest in a £350 million subsea cable factory at a neighbouring site on the Cromarty Firth, which is due to open for operational use next September. The first Scottish recruits for Sumitomo Electric's operations team have been sent to Japan for six months of training. Following Mitsui's takeover deal of the Port of Nigg, the company said it planned to expand the manufacturing capacity at the site by investing in its infrastructure to help support both the onshore and offshore industry. The Port of Nigg has received around £120m worth of investment, including some public funding, in the past 14 years to upgrade its facilities. In January 2023, the Port of Nigg was designated as a green freeport, alongside Forth Ports, and is able to offer tax incentives and lower tariffs within the zones it covers. However, green freeports have commitments to meeting net-zero targets and supporting fair work practices. In February, HMRC gave the Port of Nigg permission to have some of its own customs arrangements, meaning taxes and certain duties on goods arriving do not have to be paid.
