Explain the Classification of Solid Waste
 Solid waste can be classified in several different ways. 
-  Putrescible waste - Animal and Vegetable waste From Cooking and 
 
-  preparing food 
 
-  Municipal solid waste- Known to the lay audience as garbage ( durable goods, 
 
-  yard trimmings, containers and packaging) 
 
-  The nature of the material may be important, so classification can be made on the 
 
-  basis of organic, inorganic, combustible, noncombustible, putrescible, and non-
 
-  putrescible. 
 
-  The classification of solid waste is usually used for choosing the treatment, 
 
-  collection, recycling, and disposal options. 
 
-  The density of solid waste is the mass of solid waste per unit volume.
