Rice straw is the dry stalk left over after the rice grains have been harvested. It is a byproduct of rice farming and is typically found in regions where rice is cultivated, such as Asia and parts of Africa. Farmers often use rice straw for various purposes, including animal bedding, composting, and as a natural fertilizer. In addition to its agricultural uses, rice straw can also be processed into products like biofuel, paper, and biodegradable packaging. Utilizing rice straw helps reduce waste and can contribute to sustainable farming practices, as it returns nutrients to the soil and minimizes environmental impact.
