We already know that bamboo charcoal can have a surface area to mass ratio of up to 600 to 1. But Borim has patented a process that can take these even higher – double to up to 1,200 square meters of surface area per 1 gram of bamboo charcoal! They do this by “activating” the bamboo charcoal, which consists of granulating the bamboo charcoal stalks into powder form and injecting it with steam. The exact process by which this occurs is a closely guarded secret, and the process in patented in South Korea.
So when we talk about “bamboo charcoal” we are referring to un-activated bamboo charcoal – these are the decorative stalks that have a multitude of household uses. Normal bamboo charcoal has the same ability to absorb chemicals and substances from the air and water, it just not have quite the holding capacity as “activated bamboo charcoal.”
Activated bamboo charcoal is used in most of our products – from our soaps and bath powders, to the multipurpose pouches and the pillows and cushions.
