Synthetic plastics are man-made materials created through chemical processes. They are derived from natural resources like oil and natural gas, which are transformed into polymers. These polymers can be molded into various shapes and forms, making synthetic plastics versatile for countless applications, from packaging to automotive parts. Common types of synthetic plastics include polyethylene, polypropylene, and polystyrene. These materials are lightweight, durable, and resistant to moisture, which contributes to their widespread use. However, the environmental impact of synthetic plastics, particularly their persistence in landfills and oceans, has raised concerns about pollution and sustainability.
