What is an example of the synthetic manufacturing process?

An example of the synthetic manufacturing process is the production of polyethylene, a widely used plastic. This process typically involves the polymerization of ethylene gas, which is derived from petroleum or natural gas. During polymerization, ethylene molecules are chemically bonded to form long chains, resulting in polyethylene resin that can be molded into various shapes for packaging, containers, and other applications. This method showcases how synthetic processes transform raw materials into valuable, usable products.
