The Ministry of Economic Affairs yesterday decided to relax regulations concerning sand and gravel extraction, as a shortage of construction material would likely affect the construction of major public infrastructure projects next year.
The relaxation includes the reopening of the Kaoping River Watershed in southern Taiwan for gravel extraction in the middle of next month, as well as opening more gravel extraction sites for the industry, Chen Tai-hsiung (
The Kaoping River Watershed, the nation's largest gravel extraction site, which supplies 40 percent of the sand and gravel used for construction in Taiwan, was closed for extraction after the Kaoping Bridge collapsed in 2000.
According to the ministry's estimate, over the past five years, domestic demand for sand and gravel has been 66 million cubic meters annually, with 40 percent extracted from rivers, 15 percent imported from China, and the remainder extracted from the ground or recycled from discarded building materials.
The construction industry has forecast demand of some 18 million cubic-meters of gravel in the first quarter of next year.
The industry is concerned that a possible shortage could affect major public works in the nation.
To meet the industry's needs, the Kaohsiung and Pingtung county governments opened some other sites, mainly land that belongs to state-run Taiwan Sugar Corp (Taisugar,
But supplies from those alternative sites will not be able to meet the industry's demand, which would negatively affect downstream industries such as the concrete sector and construction companies, Chen said.
Gravel companies once turned to Hualien County in eastern Taiwan, but found that transportation costs for shipping gravel from there are high, Chen said.
Hualien supplies around 50 million cubic meters of sand and gravel per year.
In addition, as an environmental impact assessment is being conducted in the Hualien area, the volume of gravel Hualien can offer is unlikely to alleviate the shortage. According to Taipei Harbor's statistics, the number of ships transporting gravel from the eastern county to Taipei Harbor last month dropped to 46 ships from October's 61 ships, a reduction of 59,862 tonnes of gravel.
To limit the effect on ongoing public construction, which is estimated to consume 40 percent of all construction-related sand and gravel, the ministry said yesterday that they will allow contractors to apply for special permits to extract gravel from the ground.
In addition to the short-term solution, Chen said the ministry also agreed to inspect 10 additional rivers for potential quarrying and carry out dredge works in the interim.
It is estimated that these rivers could provide 22 million cubic meters of gravel a year.
Furthermore, the ministry will negotiate with related departments to relax restrictions on ground quarries in various sites, he added.
But the last proposal may not be put into practice for a short time, as residents at the proposed quarry sites may launch demonstrations, as has occured in the past, said Cheng Chen-fan (
"Many sand and gravel plants were shuttered one by one due to the predicament during the past three years," Cheng said. "The government should have acted earlier."
The shortage also drove up the price of sand and gravel, from NT$700 per cubic meter in northern Taiwan and NT$400 per cubic meter in southern Taiwan, to NT$800 and NT$400, respectively, Cheng said.
The prices are expected to fall back next year, as the reopening of the Kaoping River Watershed will help to supply 22 million cubic meters of sand and gravel for the first four months of the year, according to the ministry.
KEEPING UP: The acquisition of a cleanroom in Taiwan would enable Micron to increase production in a market where demand continues to outpace supply, a Micron official said Micron Technology Inc has signed a letter of intent to buy a fabrication site in Taiwan from Powerchip Semiconductor Manufacturing Corp (力積電) for US$1.8 billion to expand its production of memory chips. Micron would take control of the P5 site in Miaoli County’s Tongluo Township (銅鑼) and plans to ramp up DRAM production in phases after the transaction closes in the second quarter, the company said in a statement on Saturday. The acquisition includes an existing 12 inch fab cleanroom of 27,871m2 and would further position Micron to address growing global demand for memory solutions, the company said. Micron expects the transaction to
Vincent Wei led fellow Singaporean farmers around an empty Malaysian plot, laying out plans for a greenhouse and rows of leafy vegetables. What he pitched was not just space for crops, but a lifeline for growers struggling to make ends meet in a city-state with high prices and little vacant land. The future agriculture hub is part of a joint special economic zone launched last year by the two neighbors, expected to cost US$123 million and produce 10,000 tonnes of fresh produce annually. It is attracting Singaporean farmers with promises of cheaper land, labor and energy just over the border.
US actor Matthew McConaughey has filed recordings of his image and voice with US patent authorities to protect them from unauthorized usage by artificial intelligence (AI) platforms, a representative said earlier this week. Several video clips and audio recordings were registered by the commercial arm of the Just Keep Livin’ Foundation, a non-profit created by the Oscar-winning actor and his wife, Camila, according to the US Patent and Trademark Office database. Many artists are increasingly concerned about the uncontrolled use of their image via generative AI since the rollout of ChatGPT and other AI-powered tools. Several US states have adopted
A proposed billionaires’ tax in California has ignited a political uproar in Silicon Valley, with tech titans threatening to leave the state while California Governor Gavin Newsom of the Democratic Party maneuvers to defeat a levy that he fears would lead to an exodus of wealth. A technology mecca, California has more billionaires than any other US state — a few hundred, by some estimates. About half its personal income tax revenue, a financial backbone in the nearly US$350 billion budget, comes from the top 1 percent of earners. A large healthcare union is attempting to place a proposal before
