Technology for utilization of waste single and double based propellants by obtaining porous propellants was worked out. The technology contains the preparation of solutions of waste propellants with concentration up to 20%, mixing with additives, forming a liquid layer with determined thickness, evaporation of some amount of the solvent, leaching liquid components with water and draying the porous propellants. The time for evaporation of some amount of the solvent was determined from the results of the rates of evaporation. The investigated additives were 1-butanol, ethylene glycol and polyethylene glycol 400. The porous propellants with specific density from 0.5 to 0.7 g/cm3 and regular distribution of voids of dimensions from 0.1 to 500 žm were obtained.
