The Oil Barrel's Plastic Legacy: A Startling Truth

Plastic is a product of petroleum or oil. In 2019, 9 million barrels of oil were used to make plastics every day worldwide. In 2010, the United States used around 191 million barrels of LPG and NGL for plastic production, along with 412 billion cubic feet of natural gas. The US also used about 12 million barrels of oil to produce plastic bags in 2019 and 17 million barrels to produce plastic water bottles in 2007. While plastic has diverse uses, it causes serious pollution and barely gets recycled. Bioplastics are a promising alternative, but they are not a panacea, and the industry is at risk of greenwashing.

Plastic bags are difficult to recycle

Plastic is derived from petroleum or oil. While it is difficult to determine the exact amount, oil is used as a raw material (feedstock) for making plastics. In the United States, natural gas and feedstocks derived from natural gas processing and crude oil refining are the primary sources of feedstock for plastics production.

Now, onto the topic of recycling plastic bags.

Plastic bags are notoriously difficult to recycle. Despite the efforts of various organizations to promote plastic bag recycling, the reality is that the process is not as straightforward as it seems. The American Progressive Bag Alliance, a lobbying group representing the Plastics Industry Association, advocates for the reusability and recyclability of plastic bags. However, their motivation lies in profiting from the continued production of plastics, rather than genuinely addressing the environmental concerns associated with plastic waste.

The challenges of recycling plastic bags are multifaceted. Firstly, there is a limited domestic capacity in the United States to handle contaminated materials. Environmental regulations, such as the Clean Air Act, impose stricter standards on domestic businesses compared to exported wastes. This discrepancy has led to a significant portion of plastic waste being exported to other countries, particularly China, which previously accepted over half of America's recycling waste. However, in 2018, China banned waste imports due to low demand for recycled plastic and high contamination rates.

Additionally, the recycling process for plastic bags is often unclear and poorly tracked. Even when plastic bags are collected at local stores or recycling centers, it is challenging to determine their final destination and subsequent form. This lack of transparency raises concerns about the effectiveness of plastic bag recycling programs.

Furthermore, economic factors play a role in the difficulty of recycling plastic bags. When oil prices are low, the market for plastic recycling diminishes. In such cases, it becomes more cost-effective for manufacturers to purchase virgin plastic rather than recycled plastic feedstock. This economic dynamic further discourages the recycling of plastic bags and perpetuates the reliance on virgin plastic production.

To address the issue of plastic bag waste, the focus should be on reducing their use rather than solely relying on recycling. Implementing strategies such as banning plastic bags, charging for compostable or recyclable alternatives, and promoting reusable bags can significantly reduce the amount of disposable bag waste. While recycling has its place, the most effective way to mitigate the environmental impact of plastic bags is to minimize their consumption in the first place.

Plastic water bottles are often made from recyclable plastic, but less than 30% are recycled

Plastic water bottles are often made from plastic resins, such as polyethylene terephthalate (PET), labelled with a Resin Identification Code (RIC) of "1". PET is a strong, lightweight plastic, often used for food and beverages, including water, soda, and carbonated drinks. While PET is fully recyclable, only about 30% of it is recycled in the United States. This is due to several challenges and limitations in the plastic recycling process.

Firstly, non-recyclable materials often end up in recycling bins, contaminating the batch and potentially damaging recycling machines. This contamination occurs when people are unsure of what can be recycled and throw all plastics into the recycling bin. Secondly, there is a financial incentive for manufacturers to choose "virgin" plastic over recycled plastic, as it is often cheaper and can push prices down. Thirdly, some towns and cities lack the resources and government support to implement municipal recycling services. Additionally, the recycling industry faces a shortage of workers due to the potential exposure to chemicals and hazardous machinery.

To address these issues, consumers can play a role by purchasing products made from recycled materials and choosing alternatives to plastic whenever possible. Governments can also implement policies to reduce single-use plastics and encourage the use of refillable and reusable containers. For example, research by Oceana found that a 10% increase in the share of beverages sold in refillable bottles could result in a 22% decrease in marine plastic bottle pollution, preventing 4.5 to 7.6 billion plastic bottles from entering the ocean annually.

Furthermore, the recycling process for plastic bottles is complex and often results in downcycling rather than true recycling. Downcycling occurs when a material is remade into an item of lower quality, preventing it from being recycled again. For instance, PET bottles are frequently downcycled into fibre or wood replacements instead of being recycled into new bottles. This breaks the loop of the recycling process, as these downcycled items typically end up in landfills or incinerators after their useful life.

While plastic water bottles are made from recyclable materials, the low recycling rate of less than 30% highlights the need for improved recycling infrastructure and consumer education to ensure a more sustainable future for plastic waste management.

Plastic production accounts for about 4% of global oil production

Plastic is derived from petroleum or oil. In 2012, plastic production accounted for about 4% of global oil production, which may have risen to 5-6% in 2019. This translates to around 9 million barrels of oil being used to make plastics every day worldwide as of 2019. In 2010, data showed that 191 million barrels of LPG and NGL were used for plastic production, along with 412 billion cubic feet of natural gas. The liquids constituted about 2.7% of the country's total petroleum consumption.

The US alone uses about 12 million barrels of oil to produce plastic bags annually, according to a 2019 statement by then-governor Andrew Cuomo. The US also uses about 17 million barrels of oil to produce plastic water bottles, according to a 2007 estimate.

The world has long been dependent on petroleum-based plastics due to their affordability, durability, and versatility. However, the environmental toll of plastic production is immense, and with rising oil prices, the economics behind plastics are being re-evaluated. A crude oil component called 'naphtha' is at the core of plastic production, generally constituting between 15-30% of crude oil by weight. When oil exceeds $100 a barrel, the cost of producing petroleum-based plastics can increase significantly.

Bioplastics have emerged as a promising alternative, offering a reduced carbon footprint and lesser environmental impact. However, they are not without their own challenges, as the bioplastic industry is especially at risk of greenwashing. Synthetic plastics can take more than 400 years to degrade, while bioplastics are not much better in terms of decomposition.

The US uses about 12 million barrels of oil to produce plastic bags

Plastic bags and petroleum are closely linked. While it is challenging to determine the precise quantity of oil used to create the diverse range of plastic bags, it is estimated that the US consumes approximately 12 million barrels of oil annually for this purpose. This estimate was confirmed by then-governor Andrew Cuomo in 2019 when he signed New York's ban on plastic bags.

Crude oil serves as a raw material, or feedstock, for plastic production, although it is not the primary feedstock source in the United States. Natural gas and feedstocks derived from natural gas processing and crude oil refining are also used in the manufacturing process. The flexibility of the petrochemical industry in terms of the feedstock it consumes adds to the complexity of tracking specific amounts and origins.

The International Energy Agency estimated that around 191 million barrels of oil were used annually for plastic production in 2010, with approximately 191 million barrels being consumed worldwide each year. This equates to roughly 9 million barrels per day. The portion of oil dedicated to plastic production varies across regions, with Europe allocating between 4% and 6% of its oil supply for this purpose, while the worldwide average is estimated at around 6%.

The demand for oil-based plastics is projected to increase, with the International Energy Agency anticipating that plastics will account for nearly half of the oil demand by the 2050s. However, the finite nature of fossil fuels, including crude oil, poses a challenge for the long-term sustainability of this industry. Synthetic plastics can take over 400 years to degrade, and while bioplastics offer a potential alternative, they currently face limitations in terms of biodegradability and compostability.

Bioplastics are not a guarantee that an item is free from fossil fuels

Plastic is derived from petroleum or crude oil. However, the amount of oil used to make plastic cannot be determined. While bioplastics are often touted as a solution to plastic pollution, they are not entirely free from fossil fuels. Bioplastics are made from renewable materials, and their advantages include a reduced use of fossil fuels, smaller carbon footprint, faster decomposition, and lower toxicity. However, it is important to note that bioplastics are not a flawless substitute for conventional plastic.

The term "bioplastic" can be misleading, as it does not always indicate that a product is biodegradable or compostable. In fact, less than 40% of bio-based plastics are designed to biodegrade. Additionally, bioplastics production can result in greater amounts of pollutants due to the fertilizers and pesticides used in agriculture and the chemical processing required to turn organic material into plastic. The use of bio-based PET, a hybrid bioplastic, has been found to have toxic effects on ecosystems and is a potential carcinogen. Furthermore, bioplastics contribute to ozone depletion and require extensive land use.

It is worth mentioning that the benefits of bioplastics are also significant. For instance, bioplastics are less toxic and do not contain bisphenol A (BPA), a hormone disruptor commonly found in traditional plastics. They also produce fewer greenhouse gas emissions over their lifetime and are biodegradable, preventing the accumulation of microplastics in the environment. However, it is important to understand that bioplastics are not a panacea for plastic pollution, and their environmental impact can vary depending on the specific type and treatment after use.

While bioplastics offer a promising alternative to traditional plastics, they are not entirely free from fossil fuels or environmental impact. The use of bio-based materials in bioplastics can vary, and even those with a high percentage of renewable content may still contain fossil fuel-based components. Therefore, it is essential to understand the limitations and potential drawbacks of bioplastics to make informed choices and manage expectations regarding their eco-friendliness.
