Wacker opens $348.84 mn polysilicon plant in Burghausen
Wacker Chemie has opened its €300 million (~$348.84 million) Etching Line Next in Burghausen, Germany, boosting hyperpure semiconductor-grade polysilicon output by 50 per cent. Backed by €50 million (~$58.14 million) in public funding, the plant supports digitalisation and AI chip demand. With 150 new jobs, it marks a major step in Wacker's aim to double semiconductor sales by 2030.
'Ultra-pure polycrystalline silicon is the purest man-made material. Everything regarding the semiconductor industry and, consequently, digital transformation revolves around this key raw material,' emphasized WACKER CEO Christian Hartel while addressing 100 guests in Burghausen, and added, 'We are the only company in Europe and the largest in the world who manufactures ultrapure polysilicon for the semiconductor industry. The Etching Line Next allows us to further consolidate our position as a global quality and technology leader.'
Bavaria's Minister-president Markus Söder also lauded the expansion project at the opening ceremony. "A strong signal for Bavaria and Germany as a business location: the opening of a state-of-the-art production line at Wacker Chemie in Burghausen worth €300 million. Hyperpure semiconductor-grade polysilicon is the basis for digitalization. Wacker Chemie is the global leader in this field. Together with the federal government, Bavaria is supporting the investment with around €50 million (~$58.14 million) in innovation funding. This is a clear commitment to Burghausen, the Bavarian chemical triangle and the high-tech chemical industry. As a whole, we are working with the new federal government to restart the economy: we are reducing energy and electricity costs, and are committed to an energy price for energy-intensive companies. The rapid expansion of renewable energies and gas-fired power plants is also important for Bavaria. We are lowering corporate taxes and launching the investment booster. But we need a quick solution to the global tariff dispute. Instead of EU bureaucracy, 'quick & easy' must be the order of the day. Only with a strong industry will we be able to maintain our success and continue to create value in the country in the future. Thank you for your loyalty to the location and all the best," said Markus Söder in his address.
Gitta Connemann, Parliamentary State Secretary to the Federal Minister for Economic Affairs and Energy (BMWE), also applauded the company's investment in the expansion of its polysilicon production. 'I congratulate WACKER on the commissioning of this groundbreaking plant. Semiconductors are the backbone of our modern economy. Without them, everything comes to a standstill. With this investment, supported by the federal and state governments, we are not only securing jobs in the region, but also strengthening Germany and Europe as a whole in the face of global competition. This is a strong signal for innovation, technological sovereignty and the future of our location.'
Growing demand for hyperpure, semiconductor-grade polysilicon
The internet, autonomous driving, Industry 4.0 – digital transformation and ever- growing data volumes in an ever-increasing number of data centers are driving the demand for polysilicon, one of the key raw materials in today's digital era.
Polysilicon in the highest grade of purity is indispensable for producing high- performance chips required, for example, in artificial intelligence applications or supercomputers. Very few companies are able to meet the more stringent purity requirements of the semiconductor industry. In the polysilicon business for over 70 years, chemical company WACKER is the world's leading producer of this key raw material in the semiconductor industry.
By investing in a new production line for semiconductor-grade polysilicon, WACKER continues to expand its activities in this sector. Compared to 2024, the company aims to double its sales to semiconductor customers by 2030. 'The new production line is a key project for our growth,' remarked WACKER CEO Christian Hartel, and elaborated further, "WACKER is a global leader in the semiconductor sector. Today, every second computer chip is made from polysilicon delivered by WACKER. Etching Line Next will not only allow us to meet the growing demands of the semiconductor industry, but also to achieve an exceptionally high product quality and a very high level of stability in production processes. Thanks to our new line, we can consistently produce polysilicon that will enable developers and manufacturers to come up with even more powerful logic and memory chips for the most demanding applications, such as artificial intelligence. In short: no polysilicon from WACKER, no AI.'
With a total expenditure of over €300 million, Etching Line Next is currently the Group's largest investment project. Construction work began in fall 2022.
Commissioning took place in stages from fall 2024. The plant recently went into operation and is already producing its first consignments. By virtue of the new production line, WACKER is increasing its production capacity for products that comply with the highest semiconductor-grade standards by more than 50 percent. This expansion in capacity will also create around 150 new jobs.
Semiconductor-grade polysilicon: purity of over 99.9999999999 percent
Cleaning the surface of the polysilicon chunks, which serve as a raw material for producing semiconductor wafers, is a complex and technically demanding process. Acids are used to remove the uppermost layer from the polysilicon surface. The chunks are then rinsed, packaged and shipped, whereby all operational steps are to a large extent automated and performed under cleanroom conditions. The ready-to-ship polysilicon now has a purity of over 99.9999999999 percent. The concentration of critical impurities is only in the parts-per-trillion range. This corresponds to not more than a grain of sugar in an Olympic-size swimming pool filled with water.
Important research and innovation projects were also initiated at the start of the project. An innovative cleaning process in conjunction with highly automated processes consistently guarantees the highest level of product purity. This enables WACKER to meet the growing quality demands that are essential to produce hyperpure silicon wafers and semiconductor chips.
Innovative technologies were also used during the planning phase. For example, production and logistics processes were planned virtually and simulated with the help of computer-aided simulation software. This resulted in significant cost savings and made it possible for the plant to be commissioned much earlier than the scheduled date.
As part of the European Union's Important Projects of Common European Interest (IPCEI) program for microelectronics and communication technologies, funding of up to €46 million has been approved for research and innovation projects initiated by WACKER. The funding bodies include the German Federal Ministry for Economic Affairs and Energy, the Bavarian Ministry for Economic Affairs, Regional Development and Energy, and the European Union.

Trump threatens Russia with severe consequences if Alaska talks fail
New Delhi, Aug 14 (UNI) A day before the Alaska talks for peace in Ukraine, Ukrainian President Volodymyr Zelenskyy accused Russian President Vladimir Putin of ''bluffing'' with no intention of making peace. Putin and US President Donald Trump are meeting in Alaska tomorrow (August 15) to discuss peace in Ukraine. The meeting at 1 am IST at a military base, will be held without the Ukrainian President who has warned that there cannot be any peace in his country if he is not included in the talks. However, the US President said Zelenskyy can be part of the subsequent talks process depending upon the outcome of the Alaska meeting. 'Putin is bluffing,'' Zelenskyy said after a meeting with German Chancellor Friedrich Merz in Berlin. ''He (Putin) is trying to exert pressure ahead of the meeting in Alaska on all sectors of the Ukrainian front. Russia is attempting to portray itself as capable of occupying all of Ukraine. That is undoubtedly what they want,'' Zelenskyy said. The US President also warned Russia of serious consequences if in the Alaska talks Putin does not agree to a ceasefire in Ukraine, implying that sanctions against Russia would be tightened. Meanwhile, the US warned of increasing secondary tariffs against India depending upon the outcome of the Alaska meeting. US Treasury Secretary Scott Bessent, in an interview with Bloomberg TV, said the decision would depend on the outcome of the Alaska meeting. He also asked the Europeans to join the US in sanctions against Russia. "We've put secondary tariffs on Indians for buying Russian oil. And I could see, If things don't go well, then sanctions or secondary tariffs could go up," Bessent said in the interview yesterday. 'It looks like he may be ready to negotiate and we put secondary tariffs on India, on the Indians, for buying Russian oil. And I could see if things don't go well, then sanctions or secondary tariffs could go up,' he said. Asked what about China who are the 'main purchasers of Russian crude,' Bessent said he is not going to get ahead of the President (Trump) but the President is best at 'creating leverage for himself.' President Trump will make it clear to President Putin that all options are on the table and 'sanctions can go up or they can also be loosened.' 'They can have a definitive life. They can go in indefinitely,' he said. Zelenskyy said Putin is also bluffing when pretending that sanctions are ineffective and not important to him. In reality, sanctions are extremely helpful and hit the Russian war economy hard. Russia indeed has several times more weapons – including artillery, three times as much. But it also suffers three times as many losses. He said Putin has no intention of making peace. ''He wants to occupy our country. And we all truly understand this. Putin will not be able to deceive anyone,'' he said while calling for sanctions against Russia by US and Europe. President Zelenskyy participated in the sixth meeting of the 'Coalition of the Willing', co-chaired by French President Emmanuel Macron, British Prime Minister Keir Starmer German Chancellor Friedrich Merz in Berlin yesterday. The meeting was also attended by U.S. Vice President JD Vance and U.S. Special Presidential Envoy for Ukraine Keith Kellogg. The participants agreed that the path to peace cannot be determined without Ukraine. Until Russia agrees to a ceasefire, partners will continue active diplomatic efforts, support for Ukraine and pressure on Russia. The participants also agreed that negotiations can only yield results if they are held under a ceasefire and if Russia does not agree to this step during the meeting in Alaska, sanctions against Russia's war economy will be strengthened. 'Coalition of the Willing' is a rhetorical term coined in early 1970s referring to a temporary international partnership created for achieving a particular objective, usually military or political nature. On March 2, the British Prime Minister said after a Summit meeting in London between 18 European leaders that the UK would work with France and other European countries to provide security guarantees for Ukraine, with a long-term goal of some peace agreement with Russia.

"Quite Sincere Efforts To End War": Putin Praises Trump Ahead Of Meeting
Moscow: Russian President Vladimir Putin on Thursday praised U.S. President Donald Trump's efforts to end the war in Ukraine, more than three years after Moscow launched its invasion, as the two leaders prepared for a pivotal U.S.–Russia summit Friday in Alaska. Following a meeting Thursday with top government officials on the summit, Putin said in a short video released by the Kremlin that the Trump administration was making "quite energetic and sincere efforts to stop the hostilities" and to "reach agreements that are of interest to all parties involved." Putin also suggested that "long-term conditions of peace between our countries, and in Europe, and in the world as a whole," could be reached under an agreement with the U.S. on nuclear arms control. In Washington, Trump said there was a 25% chance that the summit would fail, but he also floated the idea that, if the meeting succeeds, he could bring Ukrainian President Volodymyr Zelenskyy to Alaska for a subsequent, three-way meeting. In a radio interview with Fox News, Trump also said he might be willing to stay in Alaska longer, depending on what happens with Putin. Meanwhile, Zelenskyy and other European leaders worked to ensure their interests are taken into account when Trump and Putin meet in Anchorage. U.K. Prime Minister Keir Starmer welcomed Zelenskyy to London on Thursday in a show of British support for Ukraine a day before the critical Trump-Putin meeting. The two embraced warmly outside Starmer's offices at 10 Downing Street without making any comments, and Zelenskyy departed about an hour later. Zelenskyy's trip to the British capital came a day after he took part in virtual meetings from Berlin with Trump and the leaders of several European countries. Those leaders said that Trump had assured them that he would make a priority of trying to achieve a ceasefire in Ukraine when he meets with Putin. Speaking after the meetings to reporters, Trump warned of "very severe consequences" for Russia if Putin doesn't agree to stop the war against Ukraine after Friday's meeting. While some European leaders, including German Chancellor Friedrich Merz and French President Emmanuel Macron, praised Wednesday's video conference with Trump as constructive, uncertainty remained over how the U.S. leader — whose rhetoric toward both Zelenskyy and Putin has evolved dramatically since retaking office this year — would conduct negotiations in the absence of any other interested parties. Both Zelenskyy and the Europeans have worried that the bilateral U.S.-Russia summit would leave them and their interests sidelined, and that any conclusions could favor Moscow and leave Ukraine and Europe's future security in jeopardy. Kremlin spokesperson Dmitry Peskov tamped down expectations for any breakthroughs from the Friday summit, saying there were no plans to sign documents and that it would be a "big mistake" to predict the results of the negotiations, according to Russian news outlet Interfax. The Kremlin on Thursday said the meeting between Trump and Putin would begin at 11:30 a.m. local time. Putin's foreign policy adviser, Yuri Ushakov, told reporters that Trump and Putin will first sit down for a one-on-one meeting followed by a meeting between the two delegations. Then talks will continue over "a working breakfast." A joint news conference will follow. Trump contradicted the Kremlin, saying that no decisions have been made about holding a news conference with Putin. The uncertainty reflects just how much about the summit, including its schedule, remains unsettled. Starmer said Wednesday that the Alaska summit could be a path to a ceasefire in Ukraine, but he also alluded to European concerns that Trump may strike a deal that forces Ukraine to cede territory to Russia. He warned that Western allies must be prepared to step up pressure on Russia if necessary. During a call Wednesday among leaders of countries involved in the "coalition of the willing" — those who are prepared to help police any future peace agreement between Moscow and Kyiv — Starmer stressed that any ceasefire deal must protect the "territorial integrity" of Ukraine. "International borders cannot be, and must not be changed by force,'' he said. Kyiv has long insisted that safeguards against future Russian attacks provided by its Western allies would be a precondition for achieving a durable end to the fighting. Yet many Western governments have been hesitant to commit military personnel. Countries in the coalition, which includes France and the U.K., have been trying for months to secure U.S. security backing, should it be required. Following Wednesday's virtual meetings, Macron said Trump told the assembled leaders that while NATO must not be part of future security guarantees, "the United States and all the parties involved should take part." "It's a very important clarification that we have received," Macron said. Trump did not reference any U.S. security commitments during his comments to reporters on Wednesday. With another high-level meeting on their country's future on the horizon, some Ukrainians expressed skepticism about the summit's prospects. Oleksandra Kozlova, 39, who works at a digital agency in Kyiv, told The Associated Press on Wednesday that she believes Ukrainians "have already lost hope" that meaningful progress can be made toward ending the war. "I don't think this round will be decisive," she said. "There have already been enough meetings and negotiations promising us, ordinary people, that something will be resolved, that things will get better, that the war will end. Unfortunately, this has not happened, so personally I don't see any changes coming." Anton Vyshniak, a car salesman in Kyiv, said Ukraine's priority now should be saving the lives of its military service members, even at the expense of territorial concessions. "At the moment, the most important thing is to preserve the lives of male and female military personnel. After all, there are not many human resources left," he said. "Borders are borders, but human lives are priceless." Zelenskyy said Thursday that Ukraine had secured the release of 84 people from Russian captivity, including both soldiers and civilians. Those freed included people held by Russia since 2014, 2016 and 2017, as well as soldiers who had defended the now Russian-occupied Ukrainian city of Mariupol, Zelenskyy wrote on Telegram. The Russian Defense Ministry said Thursday that it too had received 84 soldiers as part of a prisoner exchange. In other developments, Russian strikes in Ukraine's Sumy region overnight Wednesday resulted in numerous injuries, Ukrainian regional officials said. A missile strike on a village in the Seredyna-Budska community wounded a 7-year-old girl and a 27-year-old man, according to regional governor Oleh Hryhorov. The girl was hospitalized in stable condition. In Russia, a Ukrainian drone attack damaged several apartment buildings in the southern city of Rostov-on-Don, near the border with Ukraine, where 13 civilians were wounded, according to acting governor of the region, Yuri Slyusar. Two of the wounded were hospitalized in serious condition, Slyusar said. (Except for the headline, this story has not been edited by NDTV staff and is published from a syndicated feed.)

Germany reviewing fate of Afghans stranded in Pakistan amid mass deportations
Pakistan has begun to deport documented Afghan refugees ahead of its September 1 deadline for them to leave, according to the United Nations, a step that could see more than 1 million Afghans expelled from the country. In total, more than one million Afghans have left Pakistan since 2023, including more than 200,000 since April. AFP File Germany is assessing whether Afghans stranded in Pakistan and awaiting resettlement will still be permitted to enter the country, Interior Minister Nancy Faeser said on Thursday as Islamabad steps up deportations. Pakistan has begun expelling documented Afghan refugees ahead of its September 1 deadline for their departure, the United Nations said, a move that could force more than one million Afghans out of the country. The group includes over 2,000 Afghans approved for relocation to Germany under an admission programme aimed at evacuating individuals deemed at risk under Taliban rule in Afghanistan. STORY CONTINUES BELOW THIS AD A source familiar with the situation told Reuters that Pakistani authorities have continued detaining Afghans for deportation across the border, even during the country's Independence Day holiday on Thursday. 'People with German admission approval are being brought to the Torkham border (between Pakistan and Afghanistan) as we speak,' the source told Reuters. German Interior Minister Alexander Dobrindt confirmed that some Afghans in Germany's resettlement scheme 'have recently drawn the attention of Pakistani authorities', and Berlin was in discussions with Islamabad over their status. 'We are reviewing whether these people can actually leave for Germany. Whether this actually happens depends on the outcome of the review process,' Dobrindt told journalists. Germany's admission programme for at-risk Afghans – launched in October 2022 by the centre-left government in office at the time – is now under review following February's migration-focused election won by conservatives. The new centre-right coalition intends to close the scheme, which had already been suspended pending an ongoing review. Since May 2021, Germany has admitted about 36,500 Afghans seen as vulnerable to Taliban crackdowns, but the conservative-led government says humanitarian migration now exceeds the country's integration capacity. STORY CONTINUES BELOW THIS AD On Wednesday, Germany's foreign ministry said it was in close contact with Pakistani authorities and using established emergency mechanisms to prevent deportations of Afghans. The interior ministry said it could not provide a timeline to determine the future of the admission programme but expects decisions soon. It did not say whether the increase in deportations from Pakistan would hasten a decision. With inputs from agencies
