Abstract:
A process for preparing a solid non-agglomerated combustible composition comprising the following steps:(a) removing perishable organic portions, iron materials and aluminum from urban solid wastes by:(i) screening the perishable organic portion,(ii) removing the iron materials by means of a magnetic separator,(iii) removing the aluminum by means of an eddy-current magnet,(b) triturating the urban solid wastes portion obtained after steps (a) (i)-(iii),(c) triturating a waste material consisting of a non-elastomeric polymeric material,(d) drying the triturated urban solid wastes and triturated non-elastomeric material of steps (b) and (c) respectively to a moisture content equal to or lower than 10%,(e) grinding the portions obtained from step (d) into bits,(f) grinding an elastomeric material into bits wherein the elastomeric material has any iron material associated therewith removed prior to said grinding,(g) mixing together the bits of urban solid waste and non-elastomeric polymeric material of step (e) and the bits of elastomeric material of step (f) in a weight ratio so that the mixture obtained has an apparent density lower than 0.6 g/cm.sup.3 and a caloric power of from 4,000 to 6,000 Kcal/Kg.
