Rice and Coffee Husk

Rice husks are the hard protective coverings of rice grains which are separated from the grains during milling process. Rice husk is an abundantly available waste material in all rice producing countries, and it contains about 30%–50% of organic carbon.  They are toxin-free, bio-degradable, and carbon-neutral making it an environmentally friendly alternative to traditional materials such as fragile ceramics and plastics.
