A Changhua City barista has found commercial success by turning used coffee grounds into recycled products.
Aside from brewing coffee with the beans grown by his parents atop the city’s Baguashan (八卦山), barista Chang Chih-min (張智閔) also sells merchandise like mosquito repellent incense, charcoal, soaps and even tea made from the skins of coffee cherries in his cafe.
Chang’s parents began growing coffee more than 10 years ago thanks to a program started by the Changhua City Farmers’ Association to help pineapple, longan berry and lychee farmers switch to new crops.

After opening Chang Coffee to help his parents sell their new crop, he said he soon found that the coffee industry was wasteful in how it used resources.
He said he started looking into sustainable recycling practices after seeing the massive amounts of coffee grounds that were the byproducts of his business.
As coffee beans are often the only commodity farmers need to harvest, the rest of the fruit is usually thrown away, Chang said.
The coffee business is also energy intensive he said, adding that coffee beans require a lot water to be cleaned before use, and brewing consumes a lot of electricity and heat.
Chang started looking into the possibility of using all that the coffee fruit has to offer, with the aim of making his business greener and more sustainable.
Traditionally in Taiwan, coffee grounds are sometimes reused as fertilizer or deodorizer Chang said.
However, studies from other countries show that that coffee grounds have insect-repelling qualities that have yet to be commercially explored, he added.
The study prompted Chang to explore business opportunities in reusing ground coffee. He eventually teamed up a former classmate who helped him design mosquito-repellent incense made from used coffee grounds.
After much trial and error, they tweaked their recipe and launched their mosquito-repelling incense, which is now sold as incense coils.
Chang said the popularity and commercial success of the repellent encouraged him to dive further into sustainable recycling and create other merchandise made from coffee byproducts such as soaps and charcoal.
“Converting coffee grounds into charcoal, through pyrolysis takes just a day, while traditional wood would require a month or so,” he said. “Drastically reducing the time for pyrolysis means a reduction in energy consumption. In addition, using coffee soaps could cut handwashing time by one-third, which also means a one-third reduction in water consumption.”
With the success of his incense, Chang said local supermarket and convenience store chains had shown interest in carrying his products.
In the spirit of his sustainable lifestyle, he said he is trying to develop solid fuel sticks made from used coffee grounds.
Once he creates the product, he said coffee ground processing plants would be able to recycle it to power their operations, thus achieving self-sustainability, which Chang called the ultimate goal of sustainable recycling.
Beijing could eventually see a full amphibious invasion of Taiwan as the only "prudent" way to bring about unification, the US Department of Defense said in a newly released annual report to Congress. The Pentagon's "Annual Report to Congress: Military and Security Developments Involving the People's Republic of China 2025," was in many ways similar to last year’s report but reorganized the analysis of the options China has to take over Taiwan. Generally, according to the report, Chinese leaders view the People's Liberation Army's (PLA) capabilities for a Taiwan campaign as improving, but they remain uncertain about its readiness to successfully seize
Taiwan is getting a day off on Christmas for the first time in 25 years. The change comes after opposition parties passed a law earlier this year to add or restore five public holidays, including Constitution Day, which falls on today, Dec. 25. The day marks the 1947 adoption of the constitution of the Republic of China, as the government in Taipei is formally known. Back then the Chinese Nationalist Party (KMT) governed China from Nanjing. When the KMT, now an opposition party in Taiwan, passed the legislation on holidays, it said that they would help “commemorate the history of national development.” That
Taiwan has overtaken South Korea this year in per capita income for the first time in 23 years, IMF data showed. Per capita income is a nation’s GDP divided by the total population, used to compare average wealth levels across countries. Taiwan also beat Japan this year on per capita income, after surpassing it for the first time last year, US magazine Newsweek reported yesterday. Across Asia, Taiwan ranked fourth for per capita income at US$37,827 this year due to sustained economic growth, the report said. In the top three spots were Singapore, Macau and Hong Kong, it said.

Snow fell on Yushan (Jade Mountain, 玉山) yesterday morning as a continental cold air mass sent temperatures below freezing on Taiwan’s tallest peak, the Central Weather Administration (CWA) said. Snowflakes were seen on Yushan’s north peak from 6:28am to 6:38am, but they did not fully cover the ground and no accumulation was recorded, the CWA said. As of 7:42am, the lowest temperature recorded across Taiwan was minus-5.5°C at Yushan’s Fengkou observatory and minus-4.7°C at the Yushan observatory, CWA data showed. On Hehuanshan (合歡山) in Nantou County, a low of 1.3°C was recorded at 6:39pm, when ice pellets fell at Songsyue Lodge (松雪樓), a
