Physical processing refers to the methods used to manipulate materials or substances through physical means. This can include techniques such as cutting, grinding, or shaping, which change the form of a material without altering its chemical composition. Industries like manufacturing and construction often rely on physical processing to create products or components. In addition to manufacturing, physical processing is also important in fields like food production and recycling. For example, in food processing, fruits and vegetables are often washed, chopped, or cooked to prepare them for consumption. Similarly, in recycling, materials like plastic and metal are physically sorted and processed to be reused in new products.
