Glanris: Revolutionary Water Filtration

Glanris 901x Biocarbon

Green without Compromise

Glanris has created a revolutionary new type of Soil Amendment and Water Filtration technology.

Through a patented manufacturing process, Glanris has turned a common waste product – rice husks – into an economical, high-performance, “dual-function” soil amendment/water filtration media: Biocarbon™.

Glanris has developed a process to turn rice hulls into water filtration media – a cleantech solution that has the potential to transform both the rice and the water management industry.
