Many Taipei drivers may have noticed that the asphalt surface on Zhishan Road in Shilin District (士林) glitters when reflecting the light, but few may know that the sparkle comes from recycled glass particles, the Environmental Protection Administration (EPA) said yesterday.
“Glass is a material that can be reused almost 100 percent, since it contains few impurities,” director of the EPA’s Recycling Fund Management Board, Lin Chien-huei (林建輝), said.
Besides being blended into asphalt, recycled glass particles can also be mixed into bricks and tiles to make lightweight, but strong, building materials, Lin said. It can also be made into decorative mosaic tiles or glass beads.
“In the past year, because prices for raw materials have been on the rise, recycled glass particles are becoming more and more sought after,” Lin said.
Bottles made of recycled glass can be sold for NT$7 each, more than double the price of just a year ago, he said.
In addition to the economical value of the recycled glass, reusing glass also means less carbon emissions, he said.
“A recycled beer bottle saves 0.8 units of electricity, enough to light a 100-watt light bulb for four hours,” Lin said.
Last year, 190,000 tonnes of glass, mostly old lighting fixtures, was collected by recyclers for reuse.
“This saved about 18,800 tonnes of carbon dioxide and enough energy to provide electricity for 950,000 families for an entire month,” he said.
Though the nation’s glass recycling rate is at an impressive 84 percent, Lin said there was still room for improvement.
“Many farmers have complained to us that beer or energy drink bottles are often thrown into their crop fields, which is not only a waste of resources, but is also dangerous as glass shards often cut their hands or legs,” Lin said.
In addition to throwing glass bottles into rice paddies or other public areas, some consumers fail to take their waste glass to recycling stations because they are either not aware of the importance of recycling or do not know where the recycling outlets are, he said.
“Many local garbage trucks collect glass separately and people are encouraged to dispose of their glass there — if not, most supermarkets or convenience stores offer recycling services,” Lin said.
The inspection equipment and data transmission system for new robotic dogs that Taipei is planning to use for sidewalk patrols were developed by a Taiwanese company, the city’s New Construction Office said today, dismissing concerns that the China-made robots could pose a security risk. The city is bringing in smart robotic dogs to help with sidewalk inspections, Taipei Deputy Mayor Lee Ssu-chuan (李四川) said on Facebook. Equipped with a panoramic surveillance system, the robots would be able to automatically flag problems and easily navigate narrow sidewalks, making inspections faster and more accurate, Lee said. By collecting more accurate data, they would help Taipei
TAKING STOCK: The USMC is rebuilding a once-abandoned airfield in Palau to support large-scale ground operations as China’s missile range grows, Naval News reported The US Marine Corps (USMC) is considering new sites for stockpiling equipment in the West Pacific to harden military supply chains and enhance mobility across the Indo-Pacific region, US-based Naval News reported on Saturday. The proposed sites in Palau — one of Taiwan’s diplomatic allies — and Australia would enable a “rapid standup of stored equipment within a year” of the program’s approval, the report said, citing documents published by the USMC last month. In Palau, the service is rebuilding a formerly abandoned World War II-era airfield and establishing ancillary structures to support large-scale ground operations “as China’s missile range and magazine

BETTER SERVICE QUALITY: From Nov. 10, tickets with reserved seats would only be valid for the date, train and route specified on the ticket, THSRC said Starting on Nov. 10, high-speed rail passengers with reserved seats would be required to exchange their tickets to board an earlier train. Passengers with reserved seats on a specific train are currently allowed to board earlier trains on the same day and sit in non-reserved cars, but as this is happening increasingly often, and affecting quality of travel and ticket sales, Taiwan High-Speed Rail Corp (THSRC) announced that it would be canceling the policy on Nov. 10. It is one of several new measures launched by THSRC chairman Shih Che (史哲) to improve the quality of service, it said. The company also said
