SHWM – Module 2 – MUNICIPAL OF SOLID WASTES HANDLING AND MANAGEMENT Material Handling  Segregation and separation of reusable/recyclable components of solid wastes is best carried out at the source of its generation.  However, special equipment may be installed and facilities created at suitable locations e.g. near transfer stations.  Such facilities are commonly developed in many countries.  Material separation can also be carried out at the site of wastes processing units to separate out commingled MSW into usable components. 4 Unit operations in MRF
SHWM – Module 2 – MUNICIPAL OF SOLID WASTES HANDLING AND MANAGEMENT 5 Assessment Time Review Question Sketch a sequence of unit operations for a mechanized waste separation system. The input waste includes paper products, food waste, glass, plastic (PETE, HDPE, and others), metals (ferrous and nonferrous), and hazardous wastes. List all the equipment that would be required for adequate separation. Include at least one shredder.
