Glanris manufactures Biocarbon media: a patented, effective, and economical designer biochar that removes metals and organics from water. Our Biocarbon is made from the world's most extensive agricultural waste product: rice hulls. This is a revolution in affordable metals removal. Competing microplastic resin products can cost 10 to 50 times more than Glanris' Biocarbon and will become environmentally persistent pollution at disposal. If you return our biochar to the ground, Biocarbon will sequester carbon for hundreds of years and qualifies for Carbon Credits.
