China Steel Corp (中鋼), the nation’s biggest steelmaker, will show how it has contributed to reducing carbon emissions and recycling waste material at a green technology show slated to open today.
“Car makers are trying to make their cars lighter to save energy. Therefore, China Steel has created high-intensity steel for vehicles,” Andrew Sung (宋志育), vice president of the company’s production division, told CNA on Saturday.
This type of strong steel can be made thinner, which can help reduce the weight of a vehicle by 10 percent. The weight loss will lead to a 6 percent to 8 percent decrease in gasoline consumption, he said during the run-up to the Taiwan International Green Industry Show (TiGiS), which runs through Thursday.
In addition, the company has developed high-quality electrical steel that can enhance motor efficiency. Each tonne of such steel is able to reduce carbon dioxide emissions by 1.51 tonnes, Sung said.
China Steel, in which the government has a stake, also supplies its surplus steam to 11 neighboring factories at a relatively low cost, which greatly reduces these factories’ use of their boilers.
“We supplied a total of 2 million metric tonnes of steam to these companies last year, which can be translated into 440,000 metric tonnes in carbon cuts per year,” he said.
The company also produces 13,500 metric tonnes of pure water made from wastewater on a daily basis.
Meanwhile, the steelmaker has been working to turn its other by-products of the iron-smelting process — slag and coal tar — into valuable assets.
Sung said that using slag to make cement could reduce carbon emissions by 1.4 tonnes, while coal tar could be processed for use in lithium batteries used to power electric vehicles.
“The transformation has hugely increased the value of our coal tar, as it is now 60 times more expensive than before,” he said.
China Steel will display these technologies at the TiGiS, which will have a total of 180 companies occupying some 320 booths.
Separately, a forum on solar power that will take place in Taipei tomorrow and on Wednesday, the biggest ever held in Asia, is expected to bolster the development of Taiwan’s green energy industry, according to the organizers.
This year’s Taipei Summit and PV Taiwan Forum, which is aimed at helping improve solar energy cooperation between Taiwan and other Asian countries, will be attended by dozens of officials from the Philippines, Thailand, Vietnam, Malaysia, Singapore and Germany, the Bureau of Foreign Trade said in a recent statement.
‘BIG LOSS’: This year might see the last generation of Huawei’s Kirin chips, as their production would stop next month because they are made using US technology Chinese tech giant Huawei Technologies Co (華為) is running out of processor chips to make smartphones due to US sanctions and would be forced to stop production of its own most advanced chips, a company executive has said, in a sign of growing damage to Huawei’s business from US pressure. Huawei, one of the biggest producers of smartphones and network equipment, is at the center of US-Chinese tension over technology and security. Washington last year cut off Huawei’s access to US components and technology, and those penalties were tightened in May, when the White House barred vendors worldwide from using US

Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday reported that revenue last month expanded 25 percent annually, but fell 12.8 percent month-on-month to NT$105.96 billion (US$3.59 billion). In the first seven months of this year, the chipmaker’s revenue surged 33.6 percent to NT$727.26 billion, compared with NT$544.46 billion a year earlier. TSMC has said it aims to grow its revenue by more than 20 percent this year. The company has since May 15 stopped taking new orders from Huawei Technologies Co (華為), its second-biggest customer after Apple Inc, due to the US’ restrictions on exports containing US technologies. TSMC has no plans to
The US stock market has been on a tear, yet the country’s economy is in the dumps. So why do so many people believe — undoubtedly incorrectly — that the stock market has decoupled from reality? The economy many people experience, while bleak, is local, personal and, for the most part, either not publicly traded or plays only a small part in the stock market’s moves. To explain why these personal experiences have so little effect on equity markets, we must look more closely at the market role of the weakest industry sectors. The surprising conclusion: The most visible and economically vulnerable
