a product made during the manufacture of something else
excess material or waste produced in addition to the primary product. Sludge is a byproduct from the manufacture of paper, for example. Many manufacturers look for innovative ways to reuse or recycle the byproducts created during the production process to reduce waste.
Output of a production process with relatively little sales value when compared to the main product.
A secondary product resulting from the production of a primary product.
A secondary product obtained while mining something else. For example, gold is often a byproduct of a copper mining operation, which means copper is the main metal mined, but some gold is also recovered.

is a product that you may or may not want, which comes along with the product you do want. For example, a light bulb gives off light and heat. You really want the light, but the heat is produced at the same time; the heat is the byproduct. Whenever we use energy we get byproducts.
Product of considerably less value than the major product. For example, the hide and offal are byproducts while beef is the major product.
