KURO-Bō Activated Charcoal

Created through an ancient Japanese technique, KURO-Bō Activated Charcoal (Binchotan) is a highly porous natural filter. When placed in water, it naturally adsorbs and reduces toxins, while removing E. Coli and enriching it with beneficial minerals – turning ordinary tap water into filtered water, with a delicious and more refreshing taste.

These statistics are based on 500ml bottles since Kuro-Bo commenced operations in January 2017. KURO-Bo could have saved 1.2 million kilograms of carbon dioxide emissions by avoiding additional bottle production and transportation. The Beverage Industry Environmental Roundtable estimates that one 500ml plastic water bottle has a carbon footprint equal to 82,8g of carbon dioxide. Total carbon footprint is calculated by factoring in processess from raw material transportation, plastic resin production, bottle production and cleaning, filling, storing and packaging.

To offset KURO-Bo’s minimal carbon footprint, we are joining the “Treevolution” and supporting Greenpop in planting trees, greening communities and empowering environmental stewards across Southern Africa. For more information on Greenpop please visit the website

I love that it can be “revitalized” every 30 days, the sweet taste of aqua pure!
