The Consumers’ Foundation said on Wednesday that the government should develop a new national standard that clearly categorizes biodegradable levels of toilet paper and facial tissue and that manufacturers should improve the labeling on their products, including providing biodegradable levels.
A survey conducted by the foundation between Aug. 12 and Sunday with 1,340 individuals showed that 77 percent of respondents were in favor of flushing away used toilet paper — 55 of whom said they already did so — while 23 percent disagreed with the practice.
The survey was held in light of a controversy over calling on people to flush used toilet paper rather than throwing it in waste bins as a way to save on disposal costs.
As toilet paper is made mainly from wood pulp, it breaks down easily in water, while facial tissue contains both wood pulp and paper additives, such as wet-strength agents, which means that it does not break down as easily, said Wu Chia-cheng (吳家誠), a foundation member and professor in the Department of Chemistry at National Taiwan Normal University.
Used toilet paper can generally be disposed of by flushing, Wu said, but given that it is difficult to differentiate between toilet paper and facial tissue from the packaging alone, manufacturers should improve packaging and labeling to highlight the differences between the two types of paper products, which would enable consumers to tell one from the other, Wu said.
As of April, the nation’s household sewer connection rate was only 18.38 percent, Wu said, adding that toilet paper should only be flushed down in areas where toilets are connected to sewage treatment systems, or where septic tanks are emptied frequently, to avoid harming the environment
Toilet paper in many other countries is made from short-fiber pulp and does not contain bactericides, whitening and bleaching agents, Wu said.
This type of paper, he said, is the main source of food for microscopic organisms that can help pollution control by metabolizing organic matter in sewage.
He said that the Ministry of Economic Affairs’ Bureau of Standards, Metrology and Inspection should establish criteria for the classification of toilet paper products’ degradable levels to help consumers distinguish between products that can be flushed in toilets from those that cannot.
Tropical depression TD22, which was over waters south of the Ryukyu Islands, is likely to develop into a tropical storm by this morning and pose a significant threat to Taiwan next week, the Central Weather Administration (CWA) said yesterday. The depression is likely to strengthen into a tropical storm named Krathon as it moves south and then veers north toward waters off Taiwan’s eastern coast, CWA forecaster Hsu Chung-yi (徐仲毅) said. Given the favorable environmental conditions for its development, TD22’s intensity would reach at least typhoon levels, Hsu said. As of 2pm yesterday, the tropical depression was about 610km east-southeast of Taiwan proper’s
Four factors led to the declaration of a typhoon day and the cancelation of classes yesterday, Taipei Mayor Chiang Wan-an (蔣萬安) said. Work and classes were canceled across Taiwan yesterday as Typhoon Krathon was forecast to make landfall in the southern part of the country. However, northern Taiwan had only heavy winds during the day and rain in the evening, leading some to criticize the cancelation. Speaking at a Taipei City Council meeting yesterday, Chiang said the decision was made due to the possibility of landslides and other problems in mountainous areas, the need to avoid a potentially dangerous commute for those
Typhoon Krathon, a military airshow and rehearsals for Double Ten National Day celebrations might disrupt flights at Taiwan Taoyuan International Airport in the first 10 days of next month, the airport’s operator said yesterday. Taoyuan International Airport Corp said in a statement that it has established a response center after the Central Weather Administration issued a sea warning for Krathon, and urged passengers to remain alert to the possibility of disruptions caused by the storm in the coming days. Flight schedules might also change while the air force conducts rehearsals and holds a final airshow for Double Ten National Day, it added. Although
SEMICONDUCTORS: TSMC is able to produce 2-nanometer chips and mass production is expected to be launched by next year, the company said In leading-edge semiconductor manufacturing China is behind Taiwan Semiconductor Manufacturing Co (TSMC) by at least 10 years as the Taiwanese chipmaker’s manufacturing process has progressed to 2 nanometers, National Science and Technology Council (NSTC) Minister Wu Cheng-wen (吳誠文) said yesterday. Wu made the remarks during a meeting of the Legislative Yuan’s Education and Culture Committee when asked by Democratic Progressive Party Legislator Wu Pei-yi (吳沛憶) about a report published in August by the Chinese version of Nikkei Asia that said Taiwan’s lead over China in chip manufacturing was only three years. She asked Wu Cheng-wen if the report was an accurate
