Pierre Loisel (
Collecting kitchen waste to feed pigs is an ancient but somewhat diminishing practice in urban Taiwan. According to the Environmental Protection Agency, less than 4 percent of nation's daily 6,000 tonnes of organic waste gets recycled in that way. Most organic waste, which makes up 20 to 30 percent of an average household's daily garbage, gets treated like regular garbage -- dumped in landfills or sent to incinerators.
Loisel, a former computer scientist who has spent the last several years of his retirement investigating alternative garbage uses, says this is a waste. He advocates that organic waste, besides that which is fed to pigs, be recycled through composting. Arguing that composting can and will be implemented across the island, Loisel says, "It's more a matter of time now, than whether it can work. With the independent backing of groups as diverse as the Homemakers Union and Foundation, Taiwan Formosa Plastics Corporation, and the Environmental Protection Agency, recycling kitchen waste into organic compost may not be so far around the corner.

Problematic pun
Several years ago, Loisel and his surrounding community began using a small incinerator sponsored by the EPA to clean up the area. The incinerator released safe carbon dioxide and steam byproducts, but was unable to handle large quantities of organic waste. The high water content of organic waste mixed with ashes creates a "big cake" at the bottom of an incinerator. "An incinerator is not a cooking stove; it's made not to boil, but to burn garbage," said Loisel.
Learning that the government had had no luck solving the "pun" cake problem with its larger incinerators either, Loisel looked for alternatives for dealing with the organic waste. After consulting National Taiwan University Agricultural Chemistry professor, Wu Sun-ho (
By 5:40am, Loisel has by himself amassed over a ton of pun. Back at his home property, Loisel mixes the pun "which includes everything from pineapple cores to clam shells, wood shavings and rice husks." Free from local farmers and furniture makers, the husks and shavings provide the crucial carbon-rich material to balance out the high nitrogen levels, which gives the decaying matter its stench. In three months, the compost is ready for use. Loisel has so far shared this compost with other farmers or used it in his own garden.
He jokes that if he, a single foreigner, can handle one ton a day, the Taiwanese government should certainly be able to do more.
Organized support
The President of the Homemakers Union and Foundation (
In 1996, the Homemakers Union and Foundation began to promote the recycling of organic waste. Their grassroots movement to recycle kitchen waste grew from 290 households in 1998 to over 5,000 households in 2000. Then, they stopped expanding because, as Chen explains, the organization realized that the government's involvement was needed in order for the process to be more effective. "We proved that collecting organic waste at a household level can work, but we need the government to use its power and policy to require every family to recycle its waste, and provide the resources to collect and process it, she told the Taipei Times.
Recycling organic waste requires the same kind of manpower, equipment, land, transportation capital, and civilian cooperation necessary in large-scale garbage collection, but Chen argues, if the government recycles organic waste properly, it is still doing its job handling garbage, just putting it to better use.
She admits, however, that the composting results so far have not been so spectacular. Chen explains that because the Taiwanese government left it up to individual neighborhood governments to "do it themselves," the attempts have often been half-hearted and haphazard.
Finding the value
In the past few years, several large companies such as Taiwan Formosa Plastics Corporation (
Two years ago, Formosa Plastics began constructing compost facilities in the towns of Mailiau and Taihsi and has plans to expand into Yunlin, Changhua, Chiayi, and Taipei. The company has also sought contracts from the government to process the organic waste, but the government has been slow to sign over such rights.
Loisel believes opposition within government arises because composting diverts garbage from traditional disposal methods, on which the government has already invested. Each of the incinerators that the government recently purchased to meet growing garbage problems has a near NT$1 billion price tag.
Loisel says, "half of that is the cost to buy it, the other half is payback to middle people. They don't like to see composting because if you recycle and compost, the incinerator will close. There's practically nothing left to burn. So they will lose their income."
From the enthusiastic cooperation he receives in the communities where he collects pun, Loisel is confident that support for this method is there. In areas where separation of garbage into organic and inorganic waste has already begun, residents have been able to reduce the overall amount they throw out in pricey official trash bags by 30 percent to 50 percent. For many, those savings are incentive enough to be more active recyclers.
Alternative methods
The Environmental Protection Agency has also begun to support the movement towards recycling kitchen waste. After all, it helped provide a NT$500,000 grant to support Loisel's compost research. From Sunday, Loisel will be holding a book signing for his recently released autobiography Son of the Planet (
Complicated questions continue to pop up about how exactly organic waste recycling should be implemented across the island. For example, should people separate their kitchen waste even further into what goes to pigs and what goes to compost? How should the compost be distributed? Would the compost be too oily or salty for some farming? But the interest at the grassroots environmental level and at the corporate level is certainly on the rise.
The use of organic compost may even help open up other markets, such as the more upstream organic foods market, which might throw a lifeline to Taiwan's farmers, struggling to survive in a harsher post-WTO environment. The rise of organic food chain stores, like Little Green City
But as Chen of the Homemakers Union points out, for composting to work and such advantages to be gained, "we can't just count on a Pierre Loisel and the Homemakers Union. We need the government, and we want the whole island to be doing it."
Cheng Ching-hsiang (鄭青祥) turned a small triangle of concrete jammed between two old shops into a cool little bar called 9dimension. In front of the shop, a steampunk-like structure was welded by himself to serve as a booth where he prepares cocktails. “Yancheng used to be just old people,” he says, “but now young people are coming and creating the New Yancheng.” Around the corner, Yu Hsiu-jao (饒毓琇), opened Tiny Cafe.

The low voter turnout for the referendum on Aug. 23 shows that many Taiwanese are apathetic about nuclear energy, but there are long-term energy stakes involved that the public needs to grasp Taiwan faces an energy trilemma: soaring AI-driven demand, pressure to cut carbon and reliance on fragile fuel imports. But the nuclear referendum on Aug. 23 showed how little this registered with voters, many of whom neither see the long game nor grasp the stakes. Volunteer referendum worker Vivian Chen (陳薇安) put it bluntly: “I’ve seen many people asking what they’re voting for when they arrive to vote. They cast their vote without even doing any research.” Imagine Taiwanese voters invited to a poker table. The bet looked simple — yes or no — yet most never showed. More than two-thirds of those
In the run-up to the referendum on re-opening Pingtung County’s Ma-anshan Nuclear Power Plant last month, the media inundated us with explainers. A favorite factoid of the international media, endlessly recycled, was that Taiwan has no energy reserves for a blockade, thus necessitating re-opening the nuclear plants. As presented by the Chinese-language CommonWealth Magazine, it runs: “According to the US Department of Commerce International Trade Administration, 97.73 percent of Taiwan’s energy is imported, and estimates are that Taiwan has only 11 days of reserves available in the event of a blockade.” This factoid is not an outright lie — that
Former Chinese Nationalist Party (KMT) chairwoman Hung Hsiu-chu’s (洪秀柱) attendance at the Chinese Communist Party’s (CPP) “Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War” parade in Beijing is infuriating, embarrassing and insulting to nearly everyone in Taiwan, and Taiwan’s friends and allies. She is also ripping off bandages and pouring salt into old wounds. In the process she managed to tie both the KMT and the Democratic Progressive Party (DPP) into uncomfortable knots. The KMT continues to honor their heroic fighters, who defended China against the invading Japanese Empire, which inflicted unimaginable horrors on the
