Taiwan’s recycling systems are labor intensive. In residential neighborhoods, scavengers collect bento boxes, cans, cardboard and PET bottles, and sell them onto nearby recycling yards where they are weighed and bundled before dispatch to resource recovery plants.
Most of the scavengers, and many of those who work in the yards, are in their sixties or older. They epitomize the country’s aging and shrinking labor pool.
When decrepitude eventually removes them from the workforce, it isn’t obvious who’ll gather recyclables from people who are too busy or too lazy to bring them out when municipal garbage trucks do their rounds. In recent years, the government has expanded welfare payments and senior-citizen stipends, so it’s uncertain whether many Taiwanese now in their fifties will show an interest in this kind of work when they reach retirement age.

Hiring foreign laborers could be one way to plug the gap, but automation and AI may offer a solution that’s more palatable to local voters.
SMART RECYCLING MACHINES
President Chain Store Corp (PCSC), which operates Taiwan’s 7-Eleven convenience stores, aims to install “Efficient and Intelligent Recycling Machines” at 200 locations across the country by the end of this year.

Such machines are much more sophisticated than the reverse vending machines (RVMs) for aluminum cans and beverage bottles that have been common in many developed countries since the 1960s. The 82,000 RVMs manufactured by Norway-based TOMRA Systems process more than 45 billion empty cans and bottles every year, TOMRA’s Web site says.
According to e-mailed answers provided by President, the 7-Eleven machines — which can handle PET bottles and dry batteries — were developed in conjunction with President Packaging Corp to implement the company’s plastics reduction initiative.
Thanks to a patented combination of AI, optical imaging and material-recognition technology, each RVM is able to separate bottles from batteries, and reject unsuitable plastics, such as HDPE, or PET bottles which contain sauce or oil. There’s no need to strip bottles of their wraparound labels before dropping them into one of the Efficient and Intelligent Recycling Machines.

Bottles can be square or round, and must be between 250ml and 2000ml in size. The machines can receive common battery types such as AA and AAA, but not button cells or smartphone power-banks.
The machines grind PET bottles into flakes. This not only reduces the volume of plastic to be recycled by up to 75 percent, but also shrinks the carbon footprint of transporting it to a plant where it’ll be sorted and transformed into materials that’ll end up in shoes, sports apparel and outdoor furniture.
The 10,000-plus members of the public who’d deposited more than two million bottles and batteries in 7-Eleven recycling machines by early May this year weren’t inspired only by environmentalist sentiments. Each time a customer exchanges five PET bottles or five batteries at a machine, he or she can receive a NT$1 shopping credit or one point in PCSC’s OPEN POINT reward scheme. What’s more, the company points out, because the RVMs are accessible 24/7, they make it easier for busy individuals to live a more sustainable lifestyle.

7-Eleven’s machines supplement a recycling system that the chain has been operating for well over a decade, but which hitherto required the involvement of a human employee every time recyclables were brought in.
According to 7-Eleven’s Web site, customers can redeem a defunct laptop for a NT$120 shopping credit. For a cellphone, they can get NT$12. For a cellphone charger, the credit is NT$3. If they bring in 500g of batteries, they’ll receive NT$8. But if the quantity is just under 500g, they’ll get nothing, and they’d be better off using one of the new machines.
(President declines to reveal the total quantity of batteries or other items 7-Eleven receives this way each year, how much it pays out in shopping credits or if it receives any government subsidies for handling recyclables.)
‘ECOFRIENDLY COIN’
Since late 2018, a Tainan-based startup has also been rolling out machines that award shopping points in return for recyclables. Fun Lead Change Co’s ECOCO machines, which are a distinctive shade of orange, have been installed at around 90 locations in 15 of Taiwan’s 22 special municipalities, counties and cities.
The name ECOCO derives from the words “ecofriendly” and “coin,” but the machines don’t reward users with actual coins. Anyone who’s downloaded the ECOCO smartphone app can insert PET bottles and certain items to accumulate points that can be used to offset purchases at 40-plus partner brands.
Partners include Everrich (which operates duty-free stores at airports), the EZ.Kon restaurant chain, Family Mart, Foodpanda and eyeglasses chain Kobayashi Optical. Different enterprises offer different rates of exchange. Some give users a NT$1 discount for 2 ECOCO points, while others give the same discount for 8 ECOCO points.
Businesses that host ECOCO machines — they may or may not be brands at which users can redeem points — rent them from Fun Lead Change, which then purchases all of the recyclables that users deposit. The company then sells those bottles and batteries to recycling plants like the one operated by Remondis Taiwan Co in Nantou County (see “Reducing Taiwan’s virgin plastics” in the May 25, 2022 edition of this newspaper).
“At first, it was difficult to get people to understand and accept our business model. Nowadays, it’s easier for us to persuade entrepreneurs to join us, because we’ve proved our model can work well in several different situations,” says Josie Chen (陳怡絪), a spokesperson for Fun Lead Change.
According to the company’s Web site, by the end of last year, ECOCO machines had processed 2,418 metric tons of recyclables, “equivalent to planting more than 250,000 trees, with about 6.2 times the annual carbon-absorption benefits of Daan Forest Park (大安森林公園).”
MAINTENANCE AND USE
The machines aren’t cheap. The first batch of RVMs was purchased from TOMRA and cost around NT$900,000 each, Chen says. The company is now deploying machines that were designed in-house and manufactured in Tainan, among them battery RVMs which cost NT$450,000 apiece. These don’t require much space, as they’re just 40cm wide, 48cm deep and 160cm tall.
Daily routine maintenance is so straightforward it can be done by an employee of the host business. How often an ECOCO technician needs to visit a particular site is influenced by how much the machine gets used, Chen says.
ECOCO users should remove labels from bottles, and put bottle caps in a separate opening. Batteries that are corroded or deformed will be rejected by the machine.
For Tainan City Government’s Environment Protection Bureau, Fun Lead Change this spring upgraded a recycling point outside a hypermarket in West Central District (中西) into a 24-hour “smart” facility. It handles aluminum cans, glass bottles (so long as they’re 8 to 38cm in length and 5 to 11cm in diameter) and PP beverage cups, as well as PET bottles and old batteries.
Tainan isn’t the only local government showing interest in this sort of technology. As reported by this newspaper (“‘Smart’ plant speeds up recycling in New Taipei City,” March 15), earlier this year the New Taipei City Government Environmental Protection Bureau began using a combination of optical and magnetic devices, robotics and AI at a facility in Wugu District (五股). The system can identify and separate 17 different kinds of recyclable materials, including paper, various metals and plastics such as PE, PP and polystyrene.
Recycling has never been easier, but some people still don’t make the effort. Research published in the July 2019 issue of the Journal of Marketing suggests that informing consumers about the specific uses of recovered materials is more likely to inspire them to recycle than vague messages about saving the Earth.
That’s very likely true — but appealing to people’s desire to get something for near-nothing, which is central to the ECOCO and 7-Eleven systems, is perhaps even more effective.

June 2 to June 8 Taiwan’s woodcutters believe that if they see even one speck of red in their cooked rice, no matter how small, an accident is going to happen. Peng Chin-tian (彭錦田) swears that this has proven to be true at every stop during his decades-long career in the logging industry. Along with mining, timber harvesting was once considered the most dangerous profession in Taiwan. Not only were mishaps common during all stages of processing, it was difficult to transport the injured to get medical treatment. Many died during the arduous journey. Peng recounts some of his accidents in
“Why does Taiwan identity decline?”a group of researchers lead by University of Nevada political scientist Austin Wang (王宏恩) asked in a recent paper. After all, it is not difficult to explain the rise in Taiwanese identity after the early 1990s. But no model predicted its decline during the 2016-2018 period, they say. After testing various alternative explanations, Wang et al argue that the fall-off in Taiwanese identity during that period is related to voter hedging based on the performance of the Democratic Progressive Party (DPP). Since the DPP is perceived as the guardian of Taiwan identity, when it performs well,
A short walk beneath the dense Amazon canopy, the forest abruptly opens up. Fallen logs are rotting, the trees grow sparser and the temperature rises in places sunlight hits the ground. This is what 24 years of severe drought looks like in the world’s largest rainforest. But this patch of degraded forest, about the size of a soccer field, is a scientific experiment. Launched in 2000 by Brazilian and British scientists, Esecaflor — short for “Forest Drought Study Project” in Portuguese — set out to simulate a future in which the changing climate could deplete the Amazon of rainfall. It is
Artifacts found at archeological sites in France and Spain along the Bay of Biscay shoreline show that humans have been crafting tools from whale bones since more than 20,000 years ago, illustrating anew the resourcefulness of prehistoric people. The tools, primarily hunting implements such as projectile points, were fashioned from the bones of at least five species of large whales, the researchers said. Bones from sperm whales were the most abundant, followed by fin whales, gray whales, right or bowhead whales — two species indistinguishable with the analytical method used in the study — and blue whales.
