1) Point sources of pollution are released when plastic is made. Point sources refer to specific, identifiable sources of pollution such as factories or industrial plants that release pollutants directly into the environment. In the case of plastic production, these point sources can include emissions from manufacturing processes, discharge of chemicals into water bodies, and release of gases into the air. 2) The two most commonly used types of plastic are polyethylene (PE) and polypropylene (PP). Polyethylene is used in products like plastic bags, bottles, and packaging materials. Polypropylene is commonly found in containers, toys, automobile parts, and medical devices. These plastics are versatile, durable, and widely used in various industries due to their properties. 3) Recycled plastics are made into new products through a process that involves collection, sorting, cleaning, shredding, melting, and reforming. First, plastics are collected from recycling programs and sorted based on their resin type. Then, they are cleaned to remove any impurities. The cleaned plastics are shredded into small pieces, melted down, and formed into pellets or flakes. These pellets or flakes can be used as raw material to manufacture new products such as recycled plastic bottles, containers, furniture, and clothing. Recycling plastics helps reduce waste, conserve resources, and minimize environmental impact.
