When you use paper products, do you think about lime?  Well you should, because lime has a vital role in both the quality of the paper products and the preservation of our land and water resources.
Ground Calcium Carbonate

Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world.  Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.  Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity.  Calcium carbonate is one of the most useful and versatile materials known to man.

A study of calcium carbonate provides important lessons about the history of the earth, since chalk, limestone and marble trace their origin to shallow water.  Thus, observation that large amounts of chalk deposits of the same age are found on many continents led to the discovery that there existed a period in which there was shallow water world-wide where shelled organisms thrived.  Some offer this as proof for the Biblical flood.  Nature returns the favor as calcium carbonate solutions from current deposits provide living organisms today with the material they need to grow their protective shells and skeletons.  Eggshells, for example, are composed of approximately 95% calcium carbonate.

CaCO3 - Calcium Carbonate for paper making

 In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper.  Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth.
