Chip waste seems to be an ideal raw material for sneakers

The Taiwanese company Ccilu recently launched shoes made partly from silicone. Not big news in itself if this raw material wasn’t actually the waste material from computer chips. They are made of silicon. Ccilu therefore uses recycled residual waste from TMSC, one of the largest chip manufacturers in the world.
Wilson Shu, founder of Ccilu, launched a pair of pressure-relieving slippers last year. Compare these slippers with the well-known Crocs. It turned out that one of the components was recycled silicon, the basic raw material for our computer chips. In addition to slippers, Hsu also launched massage slippers and sports shoes. Before you rush to the store to pick up an original end-of-year gift, the shoes are currently only available in Taiwan and the US for the low price of $41.
Circular footwork
Hsu’s company didn’t come up with the idea of doing circular legwork out of nowhere. The former Citibank director founded the company in 2012, reports Tom’s Hardware. The first environmentally friendly footwear became widespread shortly before the corona pandemic. At that time, Ccilu launched shoes made from recycled coffee grounds (Xpresole) and recycled PET bottles (GreenPlax). Last year, Ccilu became the first company to turn silicon waste, used to make computer chips, into shoes. The company works with Semisils Applied Materials, which is responsible for processing silicon waste.
Hsu uses the stiff material silicone for pressure points in the sole of the shoe. This is said to have a positive effect on health and even massage the feet. By reusing the silicone, the shoe also has a positive effect on the living environment. Because per pair of round shoes, the consumption of petroleum would be reduced by half a kilogram. CO2 emissions would even fall by one kilo per pair. Hsu is already excited about the collaboration and the positive impact on people and the environment. “TSMC is sometimes referred to as the ‘sacred mountain’ that protects Taiwan. Why shouldn’t we make “holy shoes” from TSMC’s silicon waste,” Hsu wonders.
