Of these methods, chemical recycling is a research field which is gaining much interest now a days, as it turns out to be that the products formed in this method are highly advantageous. 4: 32. Methods of recycling depend on the content and include waste incineration, burial in designated areas, dumping at sea. In this process of producing reclaimed rubber, breakage of crosslinking points in the crosslinked rubber occurs selectively under the controls of shear stress, reaction temperature, and internal pressure in a modular screw type reactor. (Figures relate to separately collected materials and may not reflect actual treatment – as a fraction may The first paper mill was placed in Spain and then paper was started being produced all over the world in mills.
