The Environmental Protection Administration (EPA) yesterday showcased the manufacturing of biodiesel refined from waste cooking oil, which the agency said is a valuable resource with the potential to generate domestic sales of about NT$3 billion (US$96.3 million) annually.
At a news conference in Taipei, EPA Department of Waste Management Director-General Wu Sheng-chung (吳盛忠) demonstrated how biodiesel can be obtained via simple chemical reactions in waste fool oil.
Pouring methanol and an alkaline fluid into a beaker filled with waste cooking oil, he said that to produce biodiesel the three liquids are first mixed in the correct proportions, with caustic soda or sodium methoxide added as a catalyst.
The solution then undergoes a process known as transesterification, during which heat and pressure are applied to transform it into biodiesel, Wu said.
It is at this stage that crude glycerine, a by-product that can be used in soapmaking, is obtained, he said.
To make industrial-grade biodiesel, the process is more sophisticated, and the end product must pass tests stipulated by the Bureau of Standards and the EU before it can be sold to oil reprocessing firms, he said.
About 26,000 tonnes of waste cooking oil were recycled in the first half of this year, Wu said.
About 10,000 tonnes were exported — predominantly to South Korea — while about 16,000 tonnes were used by local firms to make biodiesel, Wu added.
He said that the amount of biodiesel exported in the same period was about 6,000 tonnes, with the biggest buyers being UK and Malaysian reprocessing firms.
As biodiesel is more costly abroad, it gives domestically produced biodiesel a competitive edge, he added.
Touting biodiesel as a clean fuel that helps the nation work toward its carbon reduction goals, Wu said that as the fuel has an oxygen content of about 18 percent, it can be fully combusted, thus driving down carbon dioxide emissions.
It is also a healthier alternative to traditional diesel, as it does not produce the potentially carcinogenic polycyclic hydrocarbons that are associated with burning diesel, he said.
He said that more than 100,000 tonnes of biodiesel are derived from recycled cooking oil every year, which have an estimated total market value of about NT$3 billion.
Biofuel is the fourth-largest primary energy source worldwide, after coal, petroleum and natural gas, and the production of biodiesel skyrocketed from 800 million liters to 26.3 billion liters between 2000 and 2013, he said.
He said that the EPA would continue talks with the Ministry of Economic Affairs to promote biodiesel.
“After putting it [biodiesel] to a test for six to 12 months, I believe that the Ministry of Economic Affairs will be more confident [in the fuel],” Wu said.
Energy Bureau Division Director Weng Cheng-yuan (翁正原) said the ministry in May last year terminated a project by state-run oil refiner CPC Corp, Taiwan, to refine biodiesel after the fuel received negative feedback from private firms, who said that biodiesel tended to cause their vehicles to generate less power.
Three batches of banana sauce imported from the Philippines were intercepted at the border after they were found to contain the banned industrial dye Orange G, the Food and Drug Administration (FDA) said yesterday. From today through Sept. 2 next year, all seasoning sauces from the Philippines are to be subject to the FDA’s strictest border inspection, meaning 100 percent testing for illegal dyes before entry is allowed, it said in a statement. Orange G is an industrial coloring agent that is not permitted for food use in Taiwan or internationally, said Cheng Wei-chih (鄭維智), head of the FDA’s Northern Center for
The Chinese military has built landing bridge ships designed to expand its amphibious options for a potential assault on Taiwan, but their combat effectiveness is limited due to their high vulnerability, a defense expert said in an analysis published on Monday. Shen Ming-shih (沈明室), a research fellow at the Institute for National Defense and Security Research, said that the deployment of such vessels as part of the Chinese People’s Liberation Army (PLA) Navy’s East Sea Fleet signals a strong focus on Taiwan. However, the ships are highly vulnerable to precision strikes, which means they could be destroyed before they achieve their intended
LOOKING NORTH: The base would enhance the military’s awareness of activities in the Bashi Channel, which China Coast Guard ships have been frequenting, an expert said The Philippine Navy on Thursday last week inaugurated a forward operating base in the country’s northern most province of Batanes, which at 185km from Taiwan would be strategically important in a military conflict in the Taiwan Strait. The Philippine Daily Inquirer quoted Northern Luzon Command Commander Lieutenant General Fernyl Buca as saying that the base in Mahatao would bolster the country’s northern defenses and response capabilities. The base is also a response to the “irregular presence this month of armed” of China Coast Guard vessels frequenting the Bashi Channel in the Luzon Strait just south of Taiwan, the paper reported, citing a
About 4.2 million tourist arrivals were recorded in the first half of this year, a 10 percent increase from the same period last year, the Tourism Administration said yesterday. The growth continues to be consistent, with the fourth quarter of this year expected to be the peak in Taiwan, the agency said, adding that it plans to promote Taiwan overseas via partnerships and major events. From January to June, 9.14 million international departures were recorded from Taiwan, an 11 percent increase from the same period last year, with 3.3 million headed for Japan, 1.52 million for China and 832,962 to South Korea,
