1. Process for the preparation of a cellulosic pulp product designed for controlled combustion to support a smoldering burn consisting essentially of:
- (a) selecting as the cellulosic pulp raw material a delignified and bleached paper pulp suitable for use in the manufacture of FDA approved paper products for food packaging;
(b) drying the cellulosic pulp raw material of step (a) to a moisture content of from about 14-18%; and
, (c) subjecting the cellulosic pulp raw material of step (b) to a pelletizing process to form substantially cylindrically shaped pellets having a moisture content within the range of about 8-10%, a density of from about 570-640 Kg/m3, a length of from about 12-40 mm, and a diameter of from about 4-10 mm, wherein the pellets have a glazed outer surface to provide controlled combustion and a smoldering burn in use.
