Final answer:
A secondary product made during the manufacturing process is referred to as a by-product. These are unintended products that occur alongside the intended ones and can often be utilized or sold, thereby contributing to the overall economic viability of the production processes.
Step-by-step explanation:
A secondary product made during the manufacturing process is often referred to as a by-product. During the transformation of natural resources into finished products in secondary sector industries, sometimes unintended products are created alongside the intended ones. For example, in the refining of crude oil to produce gasoline, petroleum jelly may be produced as a by-product.
These secondary products can often be utilized or sold, creating additional revenue streams for the company. The goal in manufacturing is to maximize efficiency and output, so by-products can play a crucial role in the overall economic viability of production processes. Moreover, continuous improvement in the production process, such as in chemical manufacturing plants, aims at increasing the yield of the primary product while also considering the potential value of any by-products.
