ABSTRACT:
The invention relates to a method for recovering secondary raw materials from garbage consisting of a nonuniform mixture of useful materials gone out of use. Said method comprises the following steps: crushing the solid components of said mixture; separating the obtained crushed mixture into fractions of the same species; and subjecting said fractions to a dehumidification process. Said dehumidification process extends continuously throughout all stages of the whole recovering process. The invention also relates to a plant for carrying through said method, said plant comprising means for crushing the solid components of said mixture; separating the obtained crushed mixture into fractions of the same species; subjecting said fractions to a dehumidification process; and transporting the material to be processed form one station to the next one. All means for processing and transporting said mixture of useful materials through the whole recovering plant are located in a outwardly hermetically closed chamber, said plant can be stationary or mobile, in particular mounted on a railroad train. Said method and plant provide waste air which does not contain any pollutants.
