Plastic production is ramping up, with a plan to triple production by 2050
Plastic is everywhere, and it is cheap to make and shockingly profitable. However, the vast majority of plastic is not recycled. In the United States, only about 5% to 6% of plastics are recycled each year, and globally, just under 10% of the world's plastic is recycled.
The problem is that recycling plastic is expensive and time-consuming. It requires costly infrastructure to collect, sort, and clean the different types of plastic, and even then, many types of plastic can only be recycled once without becoming defective or contaminated. As a result, most plastic ends up in landfills, and a significant amount ends up in the oceans, severely impacting marine life.
Despite the plastic pollution crisis, plastic production is ramping up, with plans to triple production by 2050 or 2060. This is due to the continued demand for plastics, which is expected to drive future oil and gas consumption. The petrochemical industry, which produces plastic, is expanding, with new complexes in the planning and announcement stages.
To address the plastic pollution crisis, proactive policies and interventions are needed. Some approaches include the production of alternative materials, biodegradable plastics, and the development of improved recycling methods. However, achieving broader sustainability goals also requires reducing virgin plastic production and energy production footprints.
It is clear that the current rate of plastic recycling is not enough to keep up with the increasing production and use of plastics. As plastic production continues to ramp up, the environmental impact will become even more hazardous unless significant changes are made.

Plastic is cheap to make and profitable, with a competitive market for recycled plastic
Plastic is cheap to produce, and its low cost is one of the reasons it is so widely used. The "ingredients" for making plastic are inexpensive, and it can be formed into its final shape very quickly, making the process of manufacturing plastic products cost-effective. The energy input required to make plastic is also relatively low compared to other materials, such as steel. Additionally, plastic is lightweight, flexible, and durable, making it a popular choice for packaging and other applications.
However, the widespread use of plastic has led to a significant environmental problem, as the majority of plastic waste is not recycled. Despite public efforts to recycle plastic, the recycling rate for plastic is extremely low. In the United States, only about 5%-6% of plastics are recycled each year, and worldwide, just under 10% of plastic is recycled. The rest often ends up in landfills or the ocean, contributing to pollution and harming marine life.
The low recycling rate of plastic can be attributed to several factors. Firstly, there is a shortage of the costly infrastructure required to collect, sort, and recycle plastic. Mechanical recycling, which involves grinding, melting, and reforming plastic, is time-intensive and expensive, especially for rural areas that cannot afford the necessary infrastructure. Additionally, the various types of plastic are largely incompatible with each other and challenging to sort and reprocess, further complicating the recycling process.
Despite the challenges, there is a strong market for recycled plastic, particularly for the most common type, PET (Polyethylene terephthalate). PET has a strong market for its byproduct, which is used to make drink bottles, food containers, and fibers for clothing. However, other types of plastic, such as the harder plastics numbered 3-7, have a smaller market due to the lower value of the raw material compared to the cost of recycling.
To improve the recycling rate of plastic, companies that produce plastic waste could subsidize plastic recycling schemes. This approach, known as extended producer responsibility (EPR), has been successful in some European countries, such as Germany and France. Additionally, increasing the recycling rate of plastic should decrease the demand for virgin polymers, making recycled plastic more competitive. However, major plastic producers have largely broken their promises to promote recycling and include more recycled plastic in their containers.

Plastic is costly to collect, sort, and recycle, with a fragmented market for recycled plastic
Plastic recycling is challenging due to the high costs of collection, sorting, and recycling, as well as the fragmented market for recycled plastic. These factors contribute to the low recycling rates observed globally.
Firstly, collecting and sorting plastic waste is an expensive endeavour. The process requires robust sorting systems to separate different types of plastics, and the variety of plastic resins and packaging formats adds to the complexity and cost. For instance, the National Association for PET Container Resources found that only 21% of plastic bottles collected for recycling were successfully turned into new products. Additionally, the contamination of recycling streams with non-recyclable materials or incorrect types of plastic incurs further costs.
Secondly, the recycling process itself is energy-intensive and costly. It involves cleaning, melting, and reforming the plastic, requiring significant energy consumption and specialised equipment. Mechanical recycling, which involves grinding, melting, and reforming plastic, is time-intensive and expensive, especially when done properly. Furthermore, the market for recycled plastic is fragmented and limited. While PET, or Polyethylene terephthalate, has a strong market for its byproduct used in beverage bottles and food containers, harder plastics numbered 3-7 have a smaller market due to the lower value of the raw material compared to the cost of recycling. This market disparity creates a disincentive for recycling certain types of plastic.
The high costs associated with plastic recycling, coupled with the low value of recycled plastic, make it economically challenging for recycling companies to operate. In many cases, throwing plastic away or using virgin plastic is more cost-effective for brands, perpetuating a throwaway culture. This is further exacerbated by the low cost of raw materials and the affordable price of new plastic, making it cheaper for consumers to dispose of plastic waste rather than recycle it.
To address these challenges, several solutions can be considered. Firstly, implementing corporate subsidies for plastic recycling schemes, as seen in successful waste recycling programmes in countries like Germany and France, could help offset the high costs of recycling. Secondly, promoting a circular economy through systems of reuse and refill, where consumers return their plastic bottles for recycling or reuse, can reduce the demand for virgin plastic. Finally, increasing consumer education about plastic waste and recycling can empower individuals to make more sustainable choices and improve the quality of recycled materials.

Plastic packaging is made from incompatible grades of plastic, with only 9% of plastic waste recycled
Plastic is a highly profitable material that is used everywhere. Unfortunately, it is also a major contributor to pollution and waste. A significant issue with plastic is that it is costly to collect and sort, and there are thousands of different types that cannot be melted down together. This means that even when plastic is placed in recycling bins, it often does not get recycled and ends up in landfills.
Plastic packaging, in particular, is often made from incompatible grades of plastic, which further complicates the recycling process. For example, polyvinyl chloride (PVC) is the world's third-most widely produced synthetic plastic polymer and is used in the building and construction industry. Despite efforts to increase its reusability, PVC is still challenging to recycle and should be avoided whenever possible. Similarly, polystyrene (PS) or Styrofoam is commonly used for food containers, cups, bowls, and packaging. However, it is not biodegradable and has a low recycling rate. Polycarbonate (PC), another common type of plastic used in baby bottles and food packaging, has been linked to various health and environmental concerns, leading several countries to ban its use in certain products.
Other types of plastic, such as polyethylene terephthalate (PET) and high-density polyethylene (HDPE), are more widely recycled. PET is often used for food and drink packaging and is usually accepted by recycling programs. HDPE, known for its strength and resistance, is used in grocery bags, milk jugs, and other durable products. However, even these recyclable plastics face challenges due to the presence of chemicals like antimony trioxide, which can be hazardous to human health.
The challenges of recycling plastic have led to a crisis, with only 9% of the world's plastic waste being recycled. This means that the vast majority of plastic ends up in landfills or, worse, in the ocean, where it breaks apart into microplastics that contaminate the environment and enter the food chain. The problem is particularly acute in fast-developing regions of East Asia, where waste collection systems may be lacking or non-existent.
To address this issue, it is crucial to reduce plastic production and improve waste management systems. Additionally, increasing recycling infrastructure and providing incentives for better collection methods can help improve the recycling rate, which currently stands at a meager 5% to 6% in the United States.

Plastic waste often ends up in landfills or incinerators, contributing to air pollution
Plastic waste is often destined for landfills or incinerators, contributing to air pollution and other environmental issues. The reality is that the majority of plastic, even when placed in recycling bins, does not get recycled. This is due to a range of factors, including the nature of plastic production, the challenges of recycling, and the economics of the waste management industry.
Firstly, plastic production is ramping up, with companies producing vast amounts of plastic packaging that are used once and then discarded. Plastic is cheap to make and highly profitable, creating a competitive market where the costs of recycling are often seen as a hindrance. Oil and gas-based plastics are particularly affordable to produce, and the raw material from recycled plastic struggles to compete on price. Additionally, the market for recycled plastic is fragmented, making it difficult for sellers to find buyers.
Secondly, the challenges of recycling plastic are significant. Most plastic packaging is made from multiple grades of plastic that are incompatible and costly to sort and reprocess. The process of recycling is energy-intensive and becomes more expensive when additional steps, such as cleaning and sorting, are required. While some facilities are attempting to reprocess certain types of plastic, the overall recycling rates remain low. For example, a Greenpeace report found that less than 5% of plastic cups and containers were being repurposed, with the rest ending up in landfills.
The economics of the waste management industry also play a role in the low recycling rates. Recycling facilities are spread out unevenly, and some areas lack the necessary machinery for efficient selection and recycling. The cost of collecting, sorting, and recycling plastic is high, and in many cases, it is cheaper to produce new plastic from oil or gas than to recycle existing plastic. This has led to a situation where even when consumers put plastic in recycling bins, much of it ends up in landfills or incinerators.
The consequences of these issues are severe. Plastic waste that is not recycled contributes to air pollution when it is incinerated, and it ends up in landfills, oceans, and other natural environments. Microplastics, formed when plastic breaks apart, have been found in snow, rainfall, human blood, and various ecosystems, highlighting the pervasive impact of plastic pollution. With plastic production set to increase, the crisis will worsen unless drastic changes are made to improve recycling infrastructure and reduce plastic consumption.
