The Plastic Problem: Petroleum's Transformation Into Plastic Products

Petroleum, or crude oil, is a fossil fuel made from animal and plant matter that has endured heat and pressure underground for millions of years. It is used to make plastic, which is created through a refining process that turns petroleum into chemicals. In 2012, plastics accounted for 4% of global oil production, and it is estimated that this figure rose to 5-6% in 2019.

The refining process: petroleum is heated to 600-750 degrees Fahrenheit and distilled, breaking it into smaller pieces called fractions

The refining process involves heating petroleum to 600-750 degrees Fahrenheit and distilling it. This process is called fractional distillation and it breaks the petroleum into smaller pieces called fractions. Fractions contain hydrocarbons, including gasoline, kerosene, diesel fuel, bitumen (or asphalt), lubricating oil, residual fuel oil, and naphtha. Naphtha is a chemical that goes on to become plastic. It is composed of many different hydrocarbons, including ethane and propene, which are the critical components of synthetic plastics. A process called steam cracking is then used to break the naphtha down into these components.

Fractional distillation is an important step in the refining process, as it allows for the separation of the different hydrocarbons present in petroleum. This separation is necessary because different hydrocarbons have different boiling points, and therefore different uses. For example, gasoline has a lower boiling point than diesel fuel, and is used for a different purpose (i.e. as a fuel for cars).

The refining process is a critical step in the production of plastic from petroleum. It allows for the separation and purification of the different hydrocarbons present in petroleum, which can then be used for a variety of purposes, including the production of plastic. The specific heating and distillation process used in the refining process helps to ensure that the final product is of a high quality and is suitable for its intended use.

The amount of petroleum that becomes plastic is difficult to determine exactly. However, it is known that plastics made a significant contribution to global oil production in 2012, accounting for 4% of the total. This figure may have risen to 5%-6% in 2019. In addition, an estimated 359 million tons of plastics entered markets around the world in 2019, of which an estimated 35% to 45% were used in packaging. This suggests that a significant amount of petroleum is used in the production of plastic.

Fractions: these contain hydrocarbons, including gasoline, kerosene, diesel fuel, bitumen, lubricating oil, residual fuel oil, and naphtha

Petroleum, or crude oil, is made from animal and plant matter that has endured heat and pressure underground for millions of years. Fractions of petroleum contain hydrocarbons, including gasoline, kerosene, diesel fuel, bitumen (or asphalt), lubricating oil, residual fuel oil, and naphtha. Naphtha is composed of many different hydrocarbons, including ethane and propene, which are the critical components of synthetic plastics.

Synthetic plastics are the biggest group of plastics and are most often made with petroleum in China, Europe, Southeast Asia, and Japan. In 2012, plastics accounted for 4% of global oil production, and this figure may have risen to 5-6% in 2019. In 2010, 191 million barrels of LPG and NGL were used for the production of plastics, along with 412 billion cu ft of natural gas. However, it is important to note that not all plastics are made from crude oil. In the United States, for example, most domestic plastic starts off as natural gas.

The process of turning petroleum into plastic involves heating the oil to 600-750 degrees Fahrenheit and distilling it through a process called fractional distillation. This breaks the oil into smaller pieces called fractions. These fractions contain the hydrocarbons mentioned earlier. A process called steam cracking then breaks the naphtha fraction down into ethane and propene, which are the building blocks of synthetic plastics.

Naphtha: composed of many different hydrocarbons, including ethane and propene, which are the critical components of synthetic plastics

Naphtha is composed of many different hydrocarbons, including ethane and propene, which are the critical components of synthetic plastics. Naphtha is a chemical that is derived from petroleum. Petroleum, or crude oil, is made from animal and plant matter that endures heat and pressure underground for millions of years.

To create petroleum plastic, the oil is heated to 600-750 degrees Fahrenheit and distilled. This process, called fractional distillation, breaks the oil into smaller pieces called fractions. Fractions contain hydrocarbons, including gasoline, kerosene, diesel fuel, bitumen (or asphalt), lubricating oil, residual fuel oil, and naphtha.

A process called steam cracking then breaks the naphtha down into ethane and propene. These two compounds are the critical components of synthetic plastics.

However, it is important to note that not all plastics are made from crude oil. In the United States, for example, most domestic plastic starts off as natural gas.

Natural gas: in the US, natural gas liquids, liquid petroleum gases, and natural gas are the most common feedstock for plastics

In the US, natural gas liquids, liquid petroleum gases, and natural gas are the most common feedstock for plastics. In 2010, some 191 million barrels of LPG and NGL were used for the production of plastics, along with 412 billion cu ft of natural gas.

Plastic production: in 2012, plastics accounted for 4% of global oil production, rising to an estimated 5-6% in 2019

Plastic production is a significant consumer of petroleum, a fossil fuel made from animal and plant matter that has endured heat and pressure underground for millions of years. In 2012, plastics accounted for 4% of global oil production, rising to an estimated 5-6% in 2019. This equates to approximately 191 million barrels of liquid petroleum gases and natural gas liquids used for plastic production in 2010, alongside 412 billion cubic feet of natural gas.

The process of converting petroleum into plastic begins with fractional distillation, where the oil is heated to 600-750 degrees Fahrenheit, breaking it down into smaller pieces called fractions. These fractions contain hydrocarbons, including gasoline, kerosene, diesel fuel, bitumen, lubricating oil, residual fuel oil, and naphtha, the latter being the chemical that becomes plastic. Naphtha is composed of various hydrocarbons, including ethane and propene, which are critical components of synthetic plastics. Steam cracking is then used to break down the naphtha into these components.

While petroleum is a significant feedstock for plastic production, it is worth noting that not all plastics are made from crude oil. In the United States, for example, most domestic plastics start as natural gas, and many plastics globally are made from natural gas feedstock. Additionally, the average portion of total plastics output used for packaging is about 35-45%, which may be less than many believe.

The International Energy Agency expects plastics to make up almost half of oil demand by the 2050s, underscoring the significant role of petroleum in plastic production and the need for sustainable alternatives.
