How are plastic bottles disposed of?
The plastic bottles are also sorted by the type of plastic they’re made from.
Then, the bottles are cleaned remove any food, liquid, or chemical residue.
Next, all of the bottles are ground up and shredded into flakes.
Finally, they are melted down and formed into small pellets, each about the size of a grain of rice..
What is the raw material of plastic bottles?
polyethylene terephthalate (PET)Typically, the plastic bottles used to hold potable water and other drinks are made from polyethylene terephthalate (PET), because the material is both strong and light.
Why is plastic harmful?
Plastic affects human health. Toxic chemicals leach out of plastic and are found in the blood and tissue of nearly all of us. Exposure to them is linked to cancers, birth defects, impaired immunity, endocrine disruption and other ailments.
How do we get plastic?
Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

Although plastic water bottles do not contain BPA, they may contain potentially harmful bacteria after they are used. It’s okay to reuse plastic water bottles, but make sure you clean the bottles with soap and hot water after use, the same as you would clean cups and dinnerware after a meal.
What materials are used to make plastic bottles?
Plastic bottles are made of polymers, which are chemically bonded to create materials such as polyethylene and polystyrene. The different raw materials of plastic bottles include polyethylene terephthalate and high-density polyethylene.
Where do plastic water bottles come from?
Plastic water bottle production Plastic water bottles are made from a petroleum product called polyethylene terephthalate (PET), which requires giant amounts of fossil fuels to make and transport. The production of bottled water uses 17 million barrels of oil a year.
How plastic is made step by step?
Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.

Who invented plastic?
A key breakthrough came in 1907, when Belgian-American chemist Leo Baekeland created Bakelite, the first real synthetic, mass-produced plastic.
What is the safest water to drink?
(Other bottles will say things like “purified” and “distilled.”) Like tap water, bottled water is generally safe to drink, although perceptions of it as “safer” than tap water are unfounded.
