Animal byproducts are materials derived from animals that are not intended for direct human consumption. These can include parts like bones, feathers, and organs, which are often used in various industries. For example, gelatin is made from animal collagen and is commonly found in food products, while leather is produced from animal hides. In addition to food and clothing, animal byproducts are also utilized in non-food items. For instance, animal fats can be used in the production of soaps and candles, while bone meal serves as a fertilizer in agriculture. These byproducts help reduce waste and maximize the use of animal resources.
