Egg shells can be used in art, nutrition, building material and many other things. Following are the different ways of using egg shells.
• Eggshells are composed of around 95% calcium carbonate, a mineral that is very important for industry, nutrition and agriculture. Many studies have been carried out to find new ways to utilize this resource. They are being looked at for treating cadmium in waste water, because of their natural absorbent properties
• Powdered egg shells are used in animal feed and pet food. There are nutritional supplements that are composed of this mineral.
• Historically the shell of an egg has been used by some artists in the recipe for white pigment.
• Some young students have experimented with eggshells instead of sand in building hollow blocks, which has been used by individual builders in some areas. Some Caribbean islands are losing their protective beaches. Individuals are illegally taking large amount of sand to make cement for building hotels for the tourist industry. Using eggshells in place of the sand will be a good option
• Mosaics, carving, painting, decoupage and washi eggs are some of the artistic use of eggshells. Crafters can make snow globes, use in terrariums, make miniature igloos, snow people and of course eggshell chalk. They can be used in home decor and as holiday ornaments

Organic waste can be converted into manure by using earthworms. This is an eco friendly way of disposing off biodegradable wastes.
In most poor or developing countries, due to the scarcity of resources, waste material is rarely thrown away. It is recycled, and the local scrap dealer will pay the person some money depending on the resale value of the goods.
On the other hand, people in developed countries often have to pay the recyclers or local municipal authorities money to dispose of their unwanted goods. To simplify the disposal of waste, families are expected to segregate the waste into the following categories:
1. Organic household waste which decomposes quickly
2. Recyclable material which is further divided into:
a. Paper: newspaper, fine paper, boxboard, corrugated, etc.
b. Metal: tinned steel cans, aluminum cans, foil, etc.
c. Plastics:PP, PVC, HDPE, LDPE
d. Glass: bottles, jars, etc.
Some companies take back the packaging they send with the goods. A fine may be imposed if the waste material is not properly segregated
