Eggs are an important raw material in the production of food. Each country has produced eggs to consumers and the food industry. So there is a lot of waste, egg shells, and also cost a lot. Cause environmental problems The provider has invented a fermented egg up so that we can reduce the amount of waste into the shell and can help fix the soil is acidic properties to the properties of neutral. Because of crushed egg shells contain calcium carbonate (CaCO3) is an element which soils need. And our experiments is to remove the soil and put the eggs into ferment. Then the pH of the fermentation broth showed that egg can become neutral, acidic soil with a real properties.
