Abstract: The present invention relates to solid fuel compositions comprising torrefied cellulosic material and a binder. Use of torrefied cellulosic material (such as wood, leaves, grass, agriproducts, or other cellulosic material), enables a preferred composition for optimizing the performance—in terms of the flame and/or heat output as well as the cost of manufactured solid fuel products, such as firelogs and fire-starters. In addition, use of torrefied cellulosic material provides a number of advantages in the manufacture of solid fuel products, including reduced storage costs and grinding costs. In addition to enabling the manufacture of a more cost-effective solid fuel products, use of torrefied cellulosic material offers environmental advantages, by providing a use of low-value wood that has few alternative uses.

Abstract: The present invention provides a system for conversion of organic matter into a torrefied product, wherein the system comprises a direct fired rotary kiln.
