WHAT IS A COMPOST BIN? A compost bin is an amount of waste, (such as organic, rotting food, dead leaves and small, dead (micro)organisms, and animal manure) put together, usually for gardens. It is similar to fertilizer, but easier to put together. The nutrients in the compost helps the soil, and plants in it to grow big, healthy, and strong. Compost bins help save money, and keep your plants/garden growing healthy and happy. Also, they get rid of rotting, old food in a person’s home.
HOW A COMPOST BIN WORKS A compost bin is a container or place with a pile of organic scraps that due to decomposers, breaks down into the soil giving nutrients to plants which eventually die go into the pile as well and start the cycle again. Oxygen Microorganisms Plants get nutrients from decomposed organics that then give plants: humus, carbon dioxide, heat And water. Then plants die and go to the compost Bin to restart the cycle.;

One example of an effect of a compost bin is giving nutrients back to the earth from decomposing plants, animals, and other decomposable materials.
Why a compost bin It helps eliminate trash by decomposing it and giving nutrients back to the earth. Creates fertilizer for the school garden. As a class, we propose that we set up a container in the cafeteria for students to place their decomposable items. This would then be taken to the compost pile by the garden.
