T'CMRF single-Sort Constituerct 7'�.s.t �igure 4 - Container Transfer The sorting regimen for the container process system is described as follows: • Ha.z�.d sorting for bulky items and unrecoverable rx�ater�als. The most cornman items removed at this sort statian, for example, are large plastic pails and buckets, items not targeted for recycling. • Mechanical screening of broken glass and fines by use o� a trommel. • Mechanical removal of steel items (mostly cans) by use af magn.ets. • Separaiion of "light" and "heavy" containers by use of an air stream (classif er). Giass, being heavy, falls through the air sfiream while plastic bottles and aluminum cans, being light, are blown in anothez direction. • Glass, separated by the air classifier, is conveyed to a sortizag Iane where brown and green glass is sorted by hand. Clear glass proceeds to the end of the lixae. • Plastic bottles at�d alu�niizum cans, separated by the air classifier, procced through a combination perforator screen which acts to further screen fi�es, perforate the plastic bottles to aid in baling and serves to split the total flow of materials onto two parallel sorting lines. • Plastic bottles are sorted by hand inio three caiegories; nahl.ral HDPE (ran�ilk jugs), pigmented HDPE (detergent bottles) and PET (soda/water bottles)_ • Alurx�num. cans are sepai-ated mechanically by eddy-current magnets. • The materials remaining on the line proceed to a t�ash container as residue.
