ABSTRACT:
Moist municipal waste is subjected to a preliminary comminuting action to reduce the size of solid constituents to less than 100 mm, and the larger heavy particles are thereupon segregated from lighter particles which include relatively small fibrous particles and relatively large additional lighter particles. The additional lighter particles are segregated from the relatively small fibrous particles and are subjected to a severing action to reduce their size to a size not exceeding that of the lighter fibrous particles. The fibrous particles are thereupon mixed with severed additional particles, and the mixture is dried and ozonized prior to classification into larger, medium-sized and smaller fractions. At least the larger fractions are used for the manufacture of shaped articles.
