Vegetables Oil

Description         : 
Used vegetable oil has a brownish color to it. When filtered, it becomes transparent, but still retains the brownish color throughout. 
Characteristics and Constituents:
The viscosity of plant and animal fats and oils varies from hard crystalline solids to light oils at room temperature. In most cases, these ‘oils’ or ‘fats’ are actually a complex mixture of various fatty acids triglycerides, often with the various components having widely varying melting points. T 
Actions and Uses : 
Conversion of waste oils and fats to biodiesel fuel is one possibility but poses some difficulties such as in the use of toxic or caustic materials and by-product disposal. Conversion to biodiesel may also decrease the economic attractiveness of using waste oils as fuels.
