Extraction
Most plastic comes from fossil fuels like gas and oil. Extracting these fuels, especially in the U.S. where gas is dominant, releases large amounts of greenhouse gases. Globally, emissions from oil extraction for plastic production are equivalent to those from over 25 million cars per year.
Refinement and Processing
-
These steps form plastic pellets, which are the main building blocks for plastic products.
Production
Plastic pellets are shipped globally for manufacturing a wide range of products. They’re lightweight and easy to transport but often spill into the environment. If ingested by animals, pellets can cause starvation and accumulate toxins like mercury.
Disposal
Plastic waste mostly ends up in landfills, incinerators, or as litter, creating more emissions. Only 9% of plastic has been recycled. As plastic breaks down into microplastics, it pollutes ecosystems, accumulates in animals, and even enters our bodies. Microplastics and associated chemicals pose health risks that are still being studied.
What are the advantages and disadvantages of using plastic?
The benefits of plastics: the production criteria are durable, low cost, water-resistant, lower energy and heavy chemicals and are lightweight.
Disadvantages of using plastics are, they pollute our environment. They pose a danger to wildlife.
