How Are Metal Chips Recycled? Metalworking and Environmental Initiatives Seen Through the Lens of Metal Chips
At CTSH, we machine solid brass and stainless steel into beautiful lighting fixtures. In the process, piles of sparkling metal fragments are created. We call these "kiriko" (metal chips).
"Kiriko" Are Not Waste, But Valuable Resources
When machining a single lighting fixture, it is not uncommon for more than half of the original material to become metal chips. However, these are by no means "waste." We carefully sort the chips by material and return them to smelters through specialized contractors. There, the melted metal is transformed back into new solid brass and stainless steel, becoming the material for the next generation of products.
High-Purity Recycling Through Integrated Production
Mixing different materials reduces the quality of recycling. Because we process the materials ourselves at our own factory, we can perfectly sort and collect brass and stainless steel without mixing them with impurities. This "high-purity cycle" is also a point of pride for us, as we handle the entire manufacturing process from start to finish in-house.
Key Points!
• A "cycle" for long-lasting use: Ensuring that the products themselves are used for a long time. At the same time, the materials produced during manufacturing are also recycled and given new life. These two pillars are how we address the reduction of environmental impact.
•Avoiding wasted energy: Minimizing the amount of material removed through precise programming is also an important part of our environmental efforts. A design measured down to a micron is also a design that eliminates wasted resources.
Together with the Rich Nature of Mirai
We continue to manufacture our products in the beautiful natural environment of Mirai City, Gifu Prefecture, where our factory is located. To continue manufacturing here with integrity for many years to come, we use every bit of material responsibly and pass it on to the future. The lights of CTSH also embody this "respect for resources."
