Belgium's Syensqo & cylib drive circularity in EV battery recycling
Syensqo and cylib have achieved a major breakthrough in circular battery recycling by producing battery-grade lithium hydroxide from spent EV batteries. Their combined technologies allow lithium recovery from various chemistries on a single line, boosting efficiency, purity, and scalabilityâ€'supporting EU targets for lithium recovery in battery waste.
A first in the battery recycling industry, this achievement enables the extraction and purification of lithium from shredded battery electrodes, known as black mass, from different battery chemistries, such as NMC (nickel-manganese-cobalt) and LFP (lithium-iron-phosphate), on a single operating line. This approach simplifies the recycling process, increases versatility and potentially reduces capital expenditures (CAPEX).
'Syensqo's technology perfectly complements cylib's hydrometallurgical process, enhancing both the yield and purity of recovered lithium,' said Laurent Cohen, in charge of Strategic Development and Alliances for Mining Solutions at Syensqo. 'By combining our expertise in solvent extraction with cylib's process, we're establishing a scalable, high-purity lithium recovery route aligned with Europe's circular economy and battery regulation goals.'
As part of the project, hundreds of liters of cylib's lithium-rich effluent were processed by Syensqo using an innovative extraction technology co-developed with its engineering partner, Tenova Advanced Technologies. The process uses CYANEX 936P, Syensqo's proprietary solvent extractant renowned for its exceptional lithium selectivity.
Following extraction, purification, conversion and crystallization, the resulting product meets, and in some respects exceeds, the strict purity standards required by leading cathode active material (CAM) manufacturers.
"This collaboration with Syensqo demonstrates our commitment to working continuously with partners to develop new processes and expand our technological leadership in battery recycling," said Matthias Breidenbach, Vice President Commercial at cylib. "By combining our innovative hydrometallurgical expertise with Syensqo's advanced solvent extraction technology, we are setting new standards for lithium recovery efficiency and purity."
This achievement also advances the objectives set by the European Union for lithium recovery in battery recycling. According to the Battery Regulation (EU) 2023/1542, adopted two years ago, recyclers must recover at least 50% of the lithium content in battery waste by the end of 2027, and no less than 80% by the end of 2031. Note: The headline, insights, and image of this press release may have been refined by the Fibre2Fashion staff; the rest of the content remains unchanged.

Ukraine flags Indian-made parts in drones used by Russian forces
Ukraine has formally raised with the Indian government and the European Union (EU) the issue of electronic components made or assembled by firms in India being found on Iranian-designed drones used by Russian armed forces, people familiar with the matter said. The Shahed, a relatively inexpensive drone, has been used in large numbers by Russia to target Ukraine since late 2022. (REUTERS) The Ukrainian side raised the matter through formal diplomatic correspondence with the external affairs ministry on at least two occasions after these components were found on Shahed 136 unmanned combat aerial vehicles (UCAVs) since last year, according to the people cited above and documents reviewed by HT. Ukrainian diplomats brought up the issue with EU sanctions envoy David O'Sullivan when he visited New Delhi in mid-July, the people added on condition of anonymity. O'Sullivan travelled to India last month to brief Indian officials on the EU's latest sanctions package, which listed Vadinar refinery, jointly owned by Russian energy major Rosneft, and included an import ban on refined products made from Russian crude. According to the documents reviewed by HT, an investigation by Ukrainian authorities established that electronic components from Vishay Intertechnology and Aura Semiconductor – either assembled or made in India – were 'used by Russia in the production of the Shahed 136' UCAVs. The documents provided detailed information and images of specific components. A 'bridge rectifier E300359' of Vishay Intertechnology assembled in India was used in the Shahed's voltage regulator unit, while a PLL-based signal generator AU5426A chip made by Aura Semiconductor was used in the jammer-proof antenna for the drone's satellite navigation system, according to the documents. The people said, purely on a technical basis, the firms have not violated any Indian laws. External affairs ministry spokesperson Randhir Jaiswal responded to a query on the matter by saying: 'India's exports of dual-use items are in keeping with its international obligations on non-proliferation, and based on its robust domestic legal and regulatory framework. Due diligence is conducted to ensure that such exports do not violate any of our laws.' There was no official word on the matter from the Ukrainian embassy in New Delhi. However, Ukraine's defence intelligence directorate or HUR has reported about the Indian-origin components found in Shahed drones on its official Facebook page and Telegram channel. Several requests for a comment from Vishay Intertechnology, a US-based manufacturer of chips, optoelectronics and sensors, elicited no reply. Kishore Ganti, co-founder of Aura Semiconductor Pvt Ltd, the Bengaluru-based subsidiary of Ningbo Aura Semiconductor Co, said the firm ensures its products are used lawfully and ethically, and fully complies with all applicable national and international export control laws. 'We are deeply disturbed by the possibility that any of our components may have reached defence manufacturers through unauthorised third-party channels, in violation of our stated compliance framework and distribution agreements. We strongly oppose such activity and are committed to taking action wherever compliance gaps are identified,' Aura Semiconductor said in a statement. Ganti said that on becoming aware of the use of an 'Aura buffer product' in the Russia-Ukraine conflict, Aura undertook a limited audit to understand the end-use for the item in question. 'However, the findings of the audit were inconclusive with respect to supply chain/end-user visibility of the Aura buffer product,' Ganti said. The component is a 'plug-and-play' one and can be used without dependence on Aura for any kind of support, 'making it difficult for Aura to trace the end users in this instance', Ganti added. The people cited above said there were instances of electronic components made in India being legally exported to destinations in West Asia, from where they were diverted to Russia or Iran. After Ukraine raised the matter, representatives of Indian security agencies visited manufacturers of electronic components and chips in Delhi, Bengaluru and Mumbai to sensitise them about international restrictions related to dual-use items, the people said. The Shahed, a relatively inexpensive drone, has been used in large numbers by Russia to target Ukraine since late 2022. According to Ukraine's Security Service or SBU, Iran initially supplied 2,000 fully assembled drones to Russia, which later established its own assembly system using Iranian ready-made parts. Data from Ukraine's air force showed Russia launched 6,129 Shahed-type drones in July. Ukraine's defence intelligence directorate has also reported that electronic components from firms in the US and China have been found on Russian drones and other weapons. Ajay Srivastava, founder of the Global Trade Research Initiative (GTRI), said the components may have been diverted by foreign buyers to Iran through third countries. 'India strictly prohibits the export of dual-use items to sanctioned destinations. However, once such goods are exported to legitimate third countries, tracing their end use becomes nearly impossible – a challenge every open economy faces,' he said. These incidents underline the need for India to strengthen exporter awareness, especially in sensitive sectors, Srivastava said. 'Exporters must be better informed about high-risk geographies and flagged entities. But no system, however rigorous, can guarantee full control once goods leave Indian borders,' he added. 'Export compliance must be enforced, but blame must not be misdirected.'

India's hard-hitting response after Trump's fresh tariff threat: Key points
Hours after US President Donald Trump threatened to raise tariffs on India over its continued purchase of Russian oil amid the ongoing Ukraine conflict, the Indian government issued a strongly worded statement on Monday questioning Washington and the European Union for their duplicity in their stance. In the statement, the Ministry of External Affairs said that India's oil imports are guided by national interests and energy security considerations and rejected what it described as "unjustified and unreasonable" pressure from Western STATEMENT - KEY TAKEAWAYS The statement issued by the Ministry of External Affairs (MEA) explained that India began buying discounted Russian oil after the Ukraine conflict disrupted global energy flows. As traditional suppliers shifted their focus to meet Europe's demand, India turned to Russia to secure its energy needs. The ministry highlighted that at the time the US in fact had 'encouraged such imports', viewing them as a means to 'strengthening global energy markets stability'. MEA also pointed out that the countries criticising India are themselves engaged in trade with Russia. However, unlike India, where such trade is a critical national necessity, their dealings lack the same justification and are 'not even a vital national compulsion'. The ministry's statement went on to explain that India's energy imports from Russia are essential to ensuring affordable and predictable fuel prices for Indian consumers. They are a necessity compelled by the global market situation. Highlighting the disparity in global trade practices, the ministry pointed out that the European Union maintained significant economic ties with Russia. In 2024, EU-Russia bilateral trade in goods reached Euro 67.5 billion, while trade in services was estimated at Euro 17.2 billion in 2023, underscoring the ongoing commercial engagement despite public criticism directed at India. The ministry also drew comparisons between India's and Europe's trade with Russia, noting that the EU's commercial engagement was significantly higher than India's total trade with Russia during the same period or afterward. It highlighted that European imports of liquefied natural gas (LNG) from Russia hit a record 16.5 million tonnes in 2024, surpassing the previous high of 15.21 million tonnes recorded in 2022. India also highlighted that Europe's trade with Russia extends well beyond energy, encompassing a wide range of sectors. This includes fertilizers, mining products, chemicals, iron and steel, as well as machinery and transport equipment. Furthermore, the ministry drew attention to US imports from Russia and said Washington continues to import uranium hexafluoride for its nuclear industry, palladium crucial to the electric vehicle sector, as well as fertilisers and various chemicals from Russia. advertisementConcluding its statement, the ministry asserted that the criticism directed at India is both unjustified and unreasonable. It said that, like any major economy, India is fully entitled to take all necessary steps to protect its national interests and ensure its economic security. The developments come after US President Donald Trump imposed a 25 per cent tariff on India from August 1, 2025 onwards. The tariff, as per Trump, comes in response to India's rates for the US which are the 'highest in the world'. Trump said that the tariff comes as a penalty for India's purchase of Russian oil and its participation in the BRICS bloc, which Trump deems as 'anti-American.' - EndsTune InMust Watch IN THIS STORY#United States of America#Donald Trump
