Abstract: It was investigated the possibility to use the waste of wood – sawdust and waste of biodiesel production – raw glycerol, for production of fuel briquettes. After the analysis of literature it was found, that it was recommended to mix sawdust with the additive – raw glycerol and to produce the fuel briquettes and to use these briquettes for burning. After the research investigations it was determined, that available in the mix optimal amount of glycerol is 20%, and the density of these received briquettes does not exceed 800 kg/m3. It was determined, that after reducing of the glycerol amount, the density of produced briquettes increased, and vice versa. With the increasing of glycerol content from 10 to 30% at the same regimes briquetting, briquettes density decreased from 79822 kg/m3 to 64812 kg/m3. And while inserting in the mix 5% of glycerol, the density of briquettes was 1100- 1300 kg/m3. It was determined, that the mechanical strength of briquettes depended on the density, and the latter – from the pressed mixture content of sawdust and glycerol. Resistance of experimental briquette for pressure varied from 0.950.08 kN (only wood sawdust) to 0.750.07 kN (after adding 20% of glycerol to wood sawdust). The same dependences were investigated of experimental briquette for the resistance to crushing. Resistance of pure wood sawdust briquettes for crushing was 95.62.5%, and after adding 20% of glycerol – 78.01.9 %
