PCT No. PCT/EP94/02015 Sec. 371 Date Jan. 19, 1996 Sec. 102(e) Date Jan. 19, 1996 PCT Filed Jun. 21, 1994 PCT Pub. No. WO95/03165 PCT Pub. Date Feb. 20, 1995The present invention pertains to the problem of compressing biomass, e.g., ripe grain or cereals, into solid pressed bodies 1, which are suitable for use as fuel, despite differences in the harvesting conditions, and whose strength no longer depends on the moisture content in the biomass. It was found that this problem can be solved without an essential expense by imparting a wavy structure 6 to the pressed body 1. As a result, the outer surface of the pressed body 1 is compressed more strongly by the extrusion than is the middle cross section area, in which long-fibered parts of the mass are readily oriented in a wave shape 21 and lead to elasticity of the pressed bodies 1, which is favorable for handling.
