Since ancient times, the Japanese created Binchotan, charcoal sticks that could fertilize soil, remove odours, and purify drinking water. What started out as a byproduct of cooking, became a useful item in its own right. Many years and several continents away, Darrin and Camilla Morrisby were going through many plastic filters per year, and knew there had to be a better way. They discovered Binchotan, and something clicked for them. They connected with a producer who makes it in the old way, by exposing wood first to very low temperatures, then in temperatures of up to 1000ºC, which causes the wood pores to enlarge, and the wood carbonises and activates its unique properties. The charcoal is removed from the kiln after 1-2 weeks, then covered in a mixture of earth, sand and ash, giving it a temporary white colour, and its name - white charcoal. Once cooled, it is hand cut and ready for use. This was the birthplace of Kuro-Bo charcoal filters.
