Gamma Meccanica has developed the new Ecotronic continuous shredder and pre-densifier for its GM recycling lines. Featuring a transmission system with electronic power control, it ensures energy savings of up to 40%, elimination of water for temperature control and recycling of either highly-printed or highly-contaminated materials with a moisture rate higher than 10%. Recently this shredder and pre-densifier has been installed on a 125 Tandem line to process 100% printed materials and on a 160 line to recycle HDPE film.
