recycling plastic :: essays research papers

Plastics are durable, lightw octet materials that were invented in 1909. They are norm anyymade from oil and natural gas. Using moldables to replace packaging materials such as surfaceand glass has allowed manufacturers to make packages that are more efficient. Forexample to bottle eight gallons of a beverage would take only two pounds of credit card moreoverwould take three pounds of aluminum, eight pounds of steel and 27 pounds of glass. Thelight weight unit of formative packaging helps reduce transportation costs. It takes fewer trucks totransport plastic compared to metal or other materials. Fewer trucks mean less supply usageand therefore less var. pollution from truck exhaust. recycle plastic containers helps to conserve landfill space and natural resourcesand to cut down on pollution. Since the number of landfills continues to diminish, keepingplastic containers out of landfills is important. Plastics do not cheapen in landfills. in that respectfore, containers you throw away will be taking up landfill space hundreds of yearsfrom now. Making plastic products from recycled plastic also reduces air and waterpollution, and energy utilise for making plastics from sore materials. Recycled plastic isused to make products such as plastic lumber, toys, containers, carpet, fiber fill for jacketsand flowerpots. There are over 1,500 products made with or packaged in recycled plastic. such uses reduce natural resource consumption and pollution because fewer raw materialsare required and less energy is needed to make recycled plastic products than to makeplastic products entirely from raw materials. There are disparate kinds mixtures of rosinsthat make thousands of types of plastics. Ink pens, car parts and plastic bags are all madefrom different resins. In order to recycle plastics, the different types mustiness be kept separate.Therefore, plastic packages are coded to indicate the type of resin used to make them. Thecode rime are found internal t he chasing cycle arrows on the bottoms of containers.These numbers help you separate plastic containers for recycling collection or drop off.Uncoded plastics, such as plastic pipes, cannot be recycled but can be reused.Recycling is a six pure tone process. First they must be cleaned and separated by thetype of plastic and by color. The first step is the most important one in the process.Colored plastics cannot be mixed with clear plastics, and plastics with different codenumbers cannot be mixed together. Mixing plastics can cause entire bales to be rejectedand possibly to be sent to a landfill. They are and then compacted and shipped off to theprocessing facility.
