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, cosmetics, and pharmaceuticals. In addition to food-related uses, animal byproducts play a role in agriculture and manufacturing. Animal fats can be used in soaps and candles, while blood can be processed into fertilizers. Overall, animal byproducts contribute to a wide range of products beyond just meat and dairy.
