Ccilu International Inc (馳綠國際), a Taiwan-based footwear brand, has become the first company in the world to turn silicon waste from contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) into eco-friendly shoes.
Last year, the global footwear industry saw the first pair of pressure-relief slippers made from recycled silicon waste by Ccilu.
The brand continued to unveil follow-up collections, including sports shoes and massage slippers made from the same materials.

In an interview with CNA, Ccilu CEO Wilson Hsu (許佳鳴) recalled the company’s innovation of the first pair of slippers made from silicon waste after its silicon waste treatment partner, Semisils Applied Materials Corp (光宇應用材料), approached him about the possible use of recycled silicon waste from TSMC and other semiconductor suppliers as shoe materials for the first time.
“I was just wondering about Ccilu’s possible purchases of TSMC’s silicon waste and turning the recycled materials into eco-friendly footwear,” Hsu said. “TSMC has been dubbed the ‘sacred mountain’ that protects Taiwan, and why would Ccilu not roll out ‘sacred shoes’ made of TSMC’s silicon waste?”
Before founding Ccilu in 2012, Hsu worked for more than a decade as a Citibank executive.
Ccilu and Semisils Applied Materials spent several years before debuting the first pair of pressure relief slippers, Hsu said.
One pair of Ccilu’s silicon waste slippers can cut the consumption of crude oil by 0.5 liters, and lower carbon emissions by 1kg, he said.
On the back of its efforts to take advantage of silicon waste, Ccilu won this year’s National Sustainable Development Awards from the National Council for Sustainable Development, symbolizing its contribution to an environmentally friendly ecosystem.
Ccilu’s silicon waste footwear failed to receive a warm reception, although he had faith that sustainable innovation has great growth potential, he said.
“Many people want to own TSMC’s shares, but not all of them like to buy shoes made from silicon waste in particular, as Ccilu’s products are not at all cheap,” he said.
A pair of pressure relief slippers carries a price tag ranging between NT$1,880 and NT$2,080 (US$59.44 and US$65.76).
“We are aware that we need more time for consumers to have a better understanding of the innovation and accept the concept of a circular economy,” he said.
“A circular economy needs everyone to participate in it in order to grow. We know it will not be an easy journey, but we will be persistent in moving forward,” he said.
Ccilu was not an instant success story, Hsu said, referring to wrong business strategies that led to massive losses from stagnant sales and a large inventory, prompting him to consider closing.
However, Hsu decided to restructure Ccilu’s business in 2017 by devoting the company’s efforts toward technology development to become an eco-friendly brand and compete in the global market.
Before the launch of the slippers made from recycled silicon, Ccilu used other waste materials such as coffee grounds and recycled polyethylene terephthalate (PET) bottles to produce shoes.
Ccilu unveiled its first pair of eco-friendly white shoes made from coffee grounds in the first half of 2020, right when the COVID-19 pandemic struck the world.
While the pandemic silenced global business activity, Ccilu turned to online marketing and sales to promote its environmental protection ideas and seek support for the company’s efforts, he said.
Ccilu raised more than NT$10 million in funding in Taiwan to produce the first shoes made from coffee grounds.
In the second half of 2020, Ccilu launched a pair of eco-friendly rain boots made from 15 recycled PET bottles after raising NT$22.5 million in funds.
Ccilu’s innovations have attracted international companies seeking cooperation, including entertainment brand Warner Bros Studio, which teamed up with the Taiwanese company to produce co-branded shoes for Wonder Woman and Batman.
Meanwhile, Ccilu has also become a partner of the PGA Tour to roll out golf shoes made from ocean waste.
In addition to the current collections of eco-friendly shoes, Hsu said Ccilu is developing pyrolysis technologies to turn used shoes into fuel for power generation, which is expected to provide electricity for shoe production.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday said that its investment plan in Arizona is going according to schedule, following a local media report claiming that the company is planning to break ground on its third wafer fab in the US in June. In a statement, TSMC said it does not comment on market speculation, but that its investments in Arizona are proceeding well. TSMC is investing more than US$65 billion in Arizona to build three advanced wafer fabs. The first one has started production using the 4-nanometer (nm) process, while the second one would start mass production using the
When an apartment comes up for rent in Germany’s big cities, hundreds of prospective tenants often queue down the street to view it, but the acute shortage of affordable housing is getting scant attention ahead of today’s snap general election. “Housing is one of the main problems for people, but nobody talks about it, nobody takes it seriously,” said Andreas Ibel, president of Build Europe, an association representing housing developers. Migration and the sluggish economy top the list of voters’ concerns, but analysts say housing policy fails to break through as returns on investment take time to register, making the
‘SILVER LINING’: Although the news caused TSMC to fall on the local market, an analyst said that as tariffs are not set to go into effect until April, there is still time for negotiations US President Donald Trump on Tuesday said that he would likely impose tariffs on semiconductor, automobile and pharmaceutical imports of about 25 percent, with an announcement coming as soon as April 2 in a move that would represent a dramatic widening of the US leader’s trade war. “I probably will tell you that on April 2, but it’ll be in the neighborhood of 25 percent,” Trump told reporters at his Mar-a-Lago club when asked about his plan for auto tariffs. Asked about similar levies on pharmaceutical drugs and semiconductors, the president said that “it’ll be 25 percent and higher, and it’ll
CHIP BOOM: Revenue for the semiconductor industry is set to reach US$1 trillion by 2032, opening up opportunities for the chip pacakging and testing company, it said ASE Technology Holding Co (日月光投控), the world’s largest provider of outsourced semiconductor assembly and test (OSAT) services, yesterday launched a new advanced manufacturing facility in Penang, Malaysia, aiming to meet growing demand for emerging technologies such as generative artificial intelligence (AI) applications. The US$300 million facility is a critical step in expanding ASE’s global footprint, offering an alternative for customers from the US, Europe, Japan, South Korea and China to assemble and test chips outside of Taiwan amid efforts to diversify supply chains. The plant, the company’s fifth in Malaysia, is part of a strategic expansion plan that would more than triple
