NOVELTY - A waste/biomass pellets are obtained using powdered calcium oxide and binding agent which is/are castor oil and/or hydrated lime, and have pellet size of 15-40 mm. The pellets comprise 40-80 wt.% biomass with 35 wt.% moisture content, 20-60 wt.% dried organic waste, and 3-5 wt. hydrated lime mixed with castor oil.    USE - Waste/biomass pellets are used as fuel for boilers.    ADVANTAGE - The waste/biomass pellets have high calorific value, and provides reduced emission of sulfur oxides in atmosphere.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) manufacture of waste/biomass pellets, which involves feeding straw via feeding table to chopper which reduces the granularity to 10 cm or less, and subsequently transporting via fan integrated with the primary impeller of the chopper to the mixer which also serves as buffer container and conveyor, after which the fragmented straw in the dispensing buffer is transported by two screw conveyors to two initial pelletizers, in which the process of final pelletization occurs accompanied by the mechanical degradation of the straw fibers. The temperature of the raw material is increased to 100 degrees C due to friction, as result of which some of the moisture evaporates, whereby the initial pelletizers are equipped with spraying system, which activates if the raw material is too dry, and when the moisture sensor indicates the value in the range of 14-18%, the raw material is transported via screw conveyors to the mixers located directly above the final pelletizers, after which it is transported to the final pelletizer, where the semi-finished material is shaped into pellets; and    (2) pelletizer head, which has conical working surface (5,5a,5b) equipped with punches (1,1a,1b) and/or sleeves (2,2a,2b), which extend into the die as tubes (4,4a,4b), whereby the sleeves and/or the punches are arranged on the working surface of the component (3,3a,3b) of the head at least in one row located along the circumference of a circle whose centre is the centre of the head, and the head is mounted on drive shaft (6,6a,6b) which connects it to the drive unit. The head comprises at least one row of concentrically arranged sleeves and/or punches.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the two co-operating pelletizer heads.    Punches (1,1a,1b)    Sleeves (2,2a,2b)    Component (3,3a,3b)    Tubes (4,4a,4b)    Working surfaces (5,5a,5b)    Drive shafts (6,6a,6b)
