A byproduct is a secondary product that is generated during the manufacturing or processing of a primary product. For example, when producing corn syrup, the leftover corn husks can be considered a byproduct. These byproducts may have value and can be used in other applications, such as animal feed or compost. Byproducts can also occur in various industries, including agriculture, mining, and chemical production. They can be beneficial, as they often reduce waste and can be repurposed, contributing to sustainability efforts. However, some byproducts may require proper disposal to prevent environmental harm.
