Code 4665 and Code 4583 “Fertilizer Mfg. & Drivers” or Code 2089 “Packing House – All Operations” shall not be assigned to the same employer unless the operations described by these classifications are conducted as separate and distinct businesses. 

Code 4665 applies to employers engaged in operating rendering works.  Rendering plants process animal by-products to produce grease, tallow and fish oils.  Animal carcasses are received from slaughterhouses and farms, fish scraps are received from fish markets, and offal and viscera are received from packing houses. 

The rendering process begins with removing hides, which in turn, are usually sold to tanneries or hide dealers.  The animal carcasses are cut to size and placed in rendering tanks with offal. 

The end products are used by various industries.
