Organic fertilizer paper is paper that can be used as fertilizer to the soil. It is made from organic materials namely egg skin, orange peel and coffee. The paper making using eggshells containing calcium carbonate can be a mineral substitute used to increase the brightness, opacity and strength of the paper. It is also potentially used to improve the appearance of paper, making it easier to print as well as smoother, opaque and brighter when used as a coating. The eggshells used contain calcium which reduces the acidity of the soil while providing nutrients to the plants. Egg yolks contain a lot of calcium which is good for the soil.
