What You'll Learn
Extraction of raw materials
The extraction of raw materials is the first step in creating plastic. The raw materials used to make plastic include natural materials such as cellulose, coal, natural gas, salt, and most commonly, crude oil. Crude oil is found deep in underground reservoirs and is extracted using large drills. This process can be done on land or at offshore drilling sites. Natural gas is also found in underground deposits, but the extraction method differs from that of crude oil. Natural gas is extracted through hydraulic fracturing or fracking, which involves shooting high-pressure streams of water, chemicals, and sand through rock to break it open and release pockets of natural gas.
The extraction of these raw materials can have significant negative impacts on the environment and human health. The use of large drills and the transportation of raw materials through pipelines, ships, and trucks pose risks of leaks and spills, leading to potential environmental damage and health hazards. The emissions from the machinery and chemicals used in the extraction process, such as benzene and other toxic chemicals, can contaminate water sources and contribute to poor air quality. Additionally, the extraction process can result in micro-earthquakes, habitat destruction, and the release of massive amounts of carbon dioxide into the atmosphere.
Crude oil, a complex mixture of thousands of compounds, undergoes distillation in an oil refinery to separate it into lighter components called fractions. Each fraction is a mixture of hydrocarbon chains, which are essential in the production of plastics. One crucial compound derived from this process is naphtha, which serves as a feedstock for the production of plastics.
The extraction and processing of raw materials for plastic production can also lead to the release of hundreds of toxins. These toxins can have detrimental effects on human health, causing damage to sensory organs, impacting bodily systems such as respiratory, nervous, and gastrointestinal, and impairing organs like the liver and brain. The exposure to toxins during the extraction process also increases the likelihood of cancer, neurological issues, and reproductive and developmental problems.
With growing environmental concerns and advancements in technology, efforts are being made to transition from traditional plastic production to more sustainable alternatives. Biodegradable plastics derived from renewable raw materials, such as corn starch, sugarcane, cellulose, and other agricultural residues, are gaining traction. These biodegradable plastics are designed to break down more quickly and naturally in the environment, helping to address the long-term plastic waste problem. Additionally, cellulosic plastics made from softwood trees offer another sustainable option, although their production is limited by anti-deforestation laws and the low cost of conventional plastics.

Health and environmental risks
Plastic is a group of materials made from organic and synthetic materials, classified as polymers. The process of making plastic is harmful to both human health and the environment.
The first step in creating plastic is to extract the raw materials, most commonly crude oil and natural gas. This extraction process can be done on land or at offshore drilling sites. Drilling for crude oil and fracking for natural gas can damage the soil and land, making the area more susceptible to natural disasters like mudslides and flash floods. Extraction companies often dump the excess rock and soil into nearby waterways, interrupting water flow and disturbing ecosystems. The extraction process also releases toxic chemicals into the air, which can lead to various health issues, including cancer, if inhaled or ingested by nearby communities.
Once extracted, the raw materials are transported to facilities for further refinement and processing. This transportation process, often involving pipelines, ships, and trucks, poses a high risk of leaks and spills, causing environmental damage and health concerns.
During the refinement and manufacturing stages, dangerous chemical compounds are used, creating toxic gas clouds around plastic factories. These chemicals have been linked to sensory and organ damage, impacting the skin, eyes, respiratory system, nervous system, gastrointestinal system, liver, and brain. The refining and manufacturing processes also release emissions that can cause reproductive and developmental issues, cancer, leukemia, and genetic problems.
The plastic-making process pollutes water, releasing tiny pellets that are consumed by fish and birds, accumulating in the food chain. These pellets contain chemicals that are toxic to aquatic animals. Additionally, the solid waste created during plastic production is often incinerated, releasing chemicals into the atmosphere.
The health and environmental risks associated with the plastic-making process extend beyond the production stage. Plastic additives, such as phthalates, heavy metals, and BPA, increase the product's toxicity and can leach out during use, directly affecting human health. The disposal of plastic waste is also a significant issue, with microplastics ending up in oceans and being mistaken as food by marine species, leading to chemical leakage that harms their bodily functions.

Toxic chemical additives
Plastic is a group of materials made from organic and synthetic materials, classified as polymers. The process of making plastic involves extracting and refining raw materials, such as crude oil and natural gas, and transforming them into polymers through heat, additives, and manipulation. This process has been labelled the Plastic "Death" Cycle by environmental advocates due to its harmful impact on health and the environment.
The release of toxins during the plastic-making process has been linked to various health issues. For instance, refining and manufacturing release emissions that can impair the nervous system, cause reproductive and developmental problems, and even lead to cancer, leukaemia, and genetic impacts. Communities located near production sites are particularly vulnerable to the daily threat of toxic exposure.
Additionally, the plastic-making process pollutes water, releasing tiny pellets that are consumed by fish and birds, accumulating in the food chain. This contributes to the growing problem of microplastics, which are ingested by marine life, causing health issues as chemicals leach out and harm their bodily functions.
The presence of toxic additives in plastics highlights the need to reduce plastic use and address the toxic plastic waste crisis. It also underscores the importance of developing a holistic, international response to the plastics crisis and strengthening policy frameworks to tackle these toxic additives effectively.

Plastic waste and pollution
The plastic production process also generates solid waste, which is often incinerated, leading to further air pollution. The disposal of plastic waste in landfills and oceans exacerbates the problem, as plastics can persist in the environment for extended periods, breaking down into microplastics that are ingested by marine life and enter the food chain. Microplastics have been found to have harmful effects on wildlife and are also present in drinking water, posing potential risks to human health.
The additives used in plastic manufacturing, such as phthalates, heavy metals, and flame retardants, further increase the toxicity of plastic products. These chemicals can leach out during use, impacting the health of individuals who come into contact with them. The recycling of plastic is challenging due to the downcycling nature of the process, and only 9% of all plastic made since 1950 has been recycled.
The plastic industry continues to expand, with global plastic production increasing drastically from 1.5 million metric tons in 1950 to about 367 million metric tons in 2020. This growth fuels a toxic cycle of plastic pollution, threatening the environment and public health. Policy responses and international treaties are being developed to address the plastic crisis, but a holistic approach is needed to tackle the interconnected issues of chemicals, waste, and petrochemicals.
To combat plastic waste and pollution, it is essential to reduce plastic consumption and break the cycle of plastic pollution. This includes advocating for stricter regulations on the plastic industry, promoting recycling and sustainable alternatives, and raising awareness about the harmful impacts of plastic on the environment and human health. By taking collective action, we can mitigate the detrimental effects of plastic waste and pollution on our planet and future generations.

Recycling and downcycling
The process of making plastic is harmful to the environment and human health. The production of plastic involves the extraction of crude oil and natural gas from underground reservoirs, which can damage the soil and land, and increase the risk of natural disasters such as mudslides and flash floods. The extraction process also releases toxic chemicals into the air, which can cause various health issues, including cancer, if inhaled or ingested. Furthermore, the transportation of raw materials and the distribution of plastic products contribute to climate-damaging emissions.
The plastic "Death" Cycle refers to the harmful process of plastic production, consumption, and disposal, which contaminates the environment at every stage. The burning of fossil fuels, the release of toxins during refining, and the use of additives in plastic manufacturing all pose significant health and environmental risks.
Recycling is one way to address the plastic waste crisis. However, the high costs and inefficiencies of recycling mean that only 9% of all plastic made since 1950 has been recycled, with the rest ending up in landfills, oceans, or being incinerated.
Downcycling is the process of converting recycled materials into new items of lesser quality or reduced functionality. While downcycling extends the lifespan of materials, it leads to a linear path towards disposal as the resulting products cannot be recycled further. For example, a plastic water bottle may be downcycled into a park bench or a polyester fleece jacket, but these items cannot be recycled again. Downcycling also faces challenges such as quality degradation, contamination concerns, and economic viability due to energy intensity and costs.
Despite its limitations, downcycling plays a role in reducing waste and promoting sustainability. It can help keep materials out of landfills and incinerators, reducing the negative impacts of waste disposal. However, it should be used in conjunction with more sustainable strategies like closed-loop recycling and upcycling, which conserve virgin resources and promote circularity. To achieve a truly circular economy, businesses must minimize single-use plastics, redesign products with sustainable materials, invest in advanced recycling technologies, and embrace circular business models.
