Plastic is all around us, but do you know where it comes from? The word plastic comes from the Greek word plastikos, which means fit for moulding. Plastics are made from natural materials such as cellulose, coal, natural gas, salt, and crude oil. The first step in making plastic is extracting these raw materials from oceans or rock formations. The next step is distillation, which separates crude oil into lighter components called fractions. One of these fractions, naphtha, is crucial for plastic production. Through polymerisation or polycondensation, plastics are formed. Synthetic plastics, which make up most of the plastic we use today, are derived from fossil fuels, while biobased plastics come from renewable sources.

What You'll Learn
Plastic comes from crude oil pumped from the ocean floor
Plastic is everywhere! From the toys we play with to the food we eat, plastic is a very useful material. But it can also cause problems for the environment. Plastic does not break down and can end up in landfills and oceans, where it can hurt animals.
Plastic comes from crude oil, which is pumped from underground through long pipes. Crude oil is a type of fossil fuel, made from the remains of tiny plants and animals called plankton. These plants and animals were buried deep beneath the Earth's surface and, over millions of years, transformed into crude oil.
To make plastic, the crude oil is heated in a big furnace, which separates it into different groups. This process is called fractional distillation. One of these groups is called naphtha, and it is used to make plastic. The naphtha is heated and turned into a liquid, which is then cooled and made into the plastic we use every day.
Most of the plastic we use is ''synthetic', which means it is made from crude oil and natural gas. However, there is another type of plastic called 'bio-based' or 'bioplastics', which is made from renewable resources like corn, beets, or potatoes. This type of plastic is better for the environment, but it is not widely used.
It is important to reduce our use of plastic, especially single-use plastic like bags and bottles, which can end up in the ocean and hurt animals. We can also recycle plastic, turning it into new things like clothing and furniture, to help reduce waste.

Plastic is made from petroleum, natural gas, or coal
Plastic is all around us—from the toys we play with to the food packaging we use every day. But did you know that most plastics are made from chemicals found in petroleum (or oil), natural gas, or coal? These materials are called fossil fuels, and they are found deep underground, sometimes even beneath the ocean floor!
Crude oil is a mixture of thousands of compounds, so it needs to be processed before it can be used. This is done through a process called refining, where the oil is heated and separated into lighter components called fractions. One of these fractions, called naphtha, is very important because it is used to make a lot of plastic.
Natural gas and coal are also used to make plastic. Natural gas is a feedstock, which means it is a basic building block for making plastic. Coal, on the other hand, is mostly made from dead plants. Scientists have also found that hydrocarbons, which are important for making plastic, can be made deep inside the Earth, in the layer between the crust and the core.
After these materials are collected and refined, they are heated and turned into molecules. Scientists then join these molecules together to make chains, and these chains become plastic! The plastic is heated and softened so that it can be poured into moulds. Once it cools down, it hardens and takes the shape of the mould.
While plastic is very useful, it can also cause problems for the environment if it is not disposed of properly. Plastic does not break down easily, so when it is thrown away, it takes up space in landfills and can end up in the oceans, harming animals. That's why it's important to recycle plastic and reduce our use of single-use plastic items like bags, bottles, and straws.

Plastic is a man-made polymer
The process of making plastic is quite complicated and requires a lot of energy and resources. It often starts with crude oil being pumped up from deep below the ocean floor. This oil is then refined and heated, which develops the chemical building blocks for many plastics. The plastic is then melted down and injected into moulds, where it takes on the shape of the mould as it cools and hardens.
Plastic can be made into almost any shape and has many important uses, such as bike helmets, car airbags, medical supplies, and water bottles. However, it is important to be careful with plastic waste, as it does not break down naturally. When thrown out, plastic waste takes up space in landfills and often ends up in the ocean, harming animals and the environment.
To reduce the negative impact of plastic, it is important to recycle it. Recycled plastic can be turned into new products such as clothing, outdoor furniture, and playground equipment. By recycling and reducing our use of unnecessary plastics, we can help protect the environment and the creatures that live in it.

Plastic is recycled into clothing, furniture, and playground equipment
Plastic is all around us, from the packaging our food comes in to the toys we play with. But did you know that plastic can be recycled and made into new things? That's right! Instead of throwing plastic away, it can be transformed into something useful like clothing, furniture, or playground equipment.
Let's start with clothing. Did you know that clothes can be made from recycled plastic bottles and ocean waste? That's right! Instead of using new plastic, companies are creating clothes from recycled plastic. This helps reduce the amount of plastic in our oceans and keeps our planet cleaner. By using recycled plastic, we can also cut down on the amount of oil used to make new plastic. So, the next time you buy a new shirt, it might be made from recycled plastic!
Now, let's talk about furniture. You might have seen benches or chairs made from plastic, but did you know that furniture can also be made from recycled plastic? That's right! People are using plastic waste to create all sorts of furniture, from chairs to tables. Recycled plastic can be used just like wood or metal, so you can make almost anything with it. Plus, it adds interesting patterns and details to your furniture. So, if you're thinking of getting new furniture, why not look for something made from recycled plastic?
Finally, let's not forget about playground equipment! You know those plastic containers like milk jugs? They can be recycled and turned into fun playground equipment! The plastic is cleaned, flattened, and then shredded into tiny pieces. Then, it's heated up and moulded into different shapes like decks, bridges, and slides. How cool is that? So, the next time you're playing on a slide or swinging on a playground, it might be made from recycled plastic!
Overall, recycling plastic is a great way to reduce waste and create something new. So, let's continue to recycle plastic and give it a new life as clothing, furniture, or playground equipment!

Plastic pollution harms marine animals
Plastic is made from chemicals that come from petroleum (oil), natural gas, or coal. The process of producing plastic takes a lot of time, energy, and resources and starts deep below the ocean floor. Crude oil is pumped up through the ground and sea through long pipes.
Plastic pollution is a serious issue that harms marine animals in various ways. Firstly, plastic debris in the ocean can entangle marine creatures, restricting their movement and leading to starvation, injury, and increased vulnerability to predators. This entanglement can be fatal, and endangered wildlife such as Hawaiian monk seals and Pacific loggerhead sea turtles are among the victims.
Secondly, marine animals often mistake plastic for food. Sea turtles, for example, may choke on plastic or suffer internal injuries, leading to death. Additionally, ingesting plastic creates a false sense of fullness, causing starvation. Research indicates that half of the sea turtles worldwide have ingested plastic, and plastic ingestion has also been observed in hundreds of thousands of seabirds annually.
Moreover, plastic in the ocean accumulates pollutants and transports them through ocean currents. Marine life that consumes this plastic coated with pollutants can absorb these toxins into their bodies. A study found that approximately 98% of seabird chicks sampled contained plastic, and the quantity of ingested plastic is increasing over time.
The impact of plastic pollution extends throughout the food chain. Fish in the North Pacific ingest 12,000 to 24,000 tons of plastic each year, transferring plastic up the food chain to larger fish, marine mammals, and eventually human seafood eaters. Apex predators, such as great white sharks and orcas, face the cumulative impact of microplastics and the bioaccumulation of toxic chemicals in their fatty tissues.
Overall, plastic pollution poses a significant threat to marine life, and it is crucial to address this issue through prevention, reduction of plastic usage, and proper waste management to protect marine ecosystems and the animals that inhabit them.
