Hazardous Waste in Metal Manufacturing Terms

Cutoffs- extra material removed from the original length of material.



Chips- small pieces of waste material cut from a machine part.



Cutting fluid- a liquid for cooling or lubricating a cutting tool and a piece of work at their point of contact.



Coolants- fluid that draws off heat by flowing through a machine or over a part being machined.


Hazardous Waste in Metal Manufacturing

Manufacturing companies have to control their waste to keep manufacturing costs low.



• Waste is part of production.

• Cut-off materials and the cutting chips are some of this waste.




Cutting fluids used in machine operations is another waste that the manufacturing industries have to control.


Manufacturing companies use water purification equipment to remove oils, particles of metal waste, and other things from the water before returning it to the drainage system.



The manufacturing community has started examining cutting and cooling fluids to make them less hazardous to the workers and the environment.


Hazardous Waste in a Flexible Metal Lab

In the Flexible Metal Lab, the waste is mainly cutting chips.




Cutting chips are cleaned up at the end of class and disposed of in an appropriate recycling bin.


Most machining in a Flexible Metal Lab is done on aluminum or brass. It also does not use a cutting or cooling fluid, so there is no waste.



If cutting fluid is needed, use hazard-free fluid.



Sheet metal waste (cutoffs of scrap sheet metal) are placed in the appropriate bins.



The Welding Lab will recycle the scrap metal.
