Plastic is everywhere, and it's shocking how profitable it is. Plastic waste is a rapidly growing segment of municipal solid waste (MSW), with containers and packaging constituting the most significant plastic tonnage. While recycling efforts are underway, the rate of plastic recycling is low. The recycling process is challenging and expensive, and most recycled materials contain unwanted toxins. The vast majority of plastic ends up in landfills, with a small percentage being incinerated or mismanaged. The solution to the plastic crisis requires systemic change, including developing better recyclable products, finding sustainable alternatives, and increasing the circularity of products.

Plastic waste often ends up in landfills, oceans or mismanaged
Plastic is cheap to make and profitable, and it has become an integral part of our lives. However, the reality is that only a small percentage of plastic is recycled. In 2018, the recycling rate for post-consumer plastic was just 8.7% globally, and in 2021, it was even lower in the United States, at 5% to 6%. The recycling rate for specific types of plastic containers, such as PET bottles and jars, was higher at 29.1% in 2018. However, the vast majority of "recycling" simply involves breaking down and melting plastic to reform it, which can lead to defects and contaminants if not done properly.
The consequences of low recycling rates are severe, as plastic waste often ends up in landfills, oceans, or is mismanaged. Half of the world's plastic goes straight to landfills, and another significant portion is mismanaged. Mismanagement of plastic waste means it is not recycled, incinerated, or stored in sealed landfills, leading to environmental pollution. This mismanaged waste enters rivers, lakes, and oceans, affecting wildlife and ecosystems. It accumulates along coastlines and shorelines, where it can persist and resurface for long periods, impacting marine life and the environment.
Rich countries produce the most plastic waste per person, but effective waste management systems keep much of it out of the natural environment. In contrast, lower-income countries often have poorer waste management infrastructure, resulting in higher rates of plastic emissions relative to their consumption. Most plastic emissions come from middle-income countries, where plastic usage is increasing, and inadequate waste management systems struggle to keep up with the rising consumption.
To address this issue, those who produce plastics need to be held accountable for the damage they cause, and the world needs to reduce its plastic production and improve recyclability. Developing sustainable alternatives and increasing circularity by keeping products in use for longer are crucial steps towards a more sustainable future. Local policies can also play a significant role in encouraging recycling, as seen in states like Maine and Oregon, which have achieved high recycling rates for PET bottles.

Mechanical recycling involves grinding, melting and reforming plastic
While the recycling rate for post-consumer plastic was just 5% to 8.7% in 2021, mechanical recycling is the most prevalent form of recycling plastic. This traditional method has been used for decades and is responsible for the majority of plastic recycling globally. Mechanical recycling involves grinding, melting, and reforming plastic.
The process begins with plastic being collected from homes, businesses, and local recycling centres and sent to Material Recovery Facilities (MRF) or Plastic Recovery Facilities (PRF). These facilities separate plastic and non-plastic items and sort plastic by type. Sorting is done manually or with specialised equipment like optical sorters. Non-recyclables are removed, and the remaining plastic waste is washed, shredded, and sorted further.
Shredding or grinding is a critical stage in recycling plastic. It involves breaking down the plastic into smaller flakes or pieces using methods like Hammer Mills or Shear Shredders. After shredding, the plastic is melted and extruded into new recycled plastic pellets or reformed into other products. This process is called extrusion, where the melted plastic is forced through an extruder and cut into pellets as it exits. These pellets are then sold to manufacturers to be used in new products.
Mechanical recycling is an important step in reducing plastic waste and promoting sustainability. However, it is time-intensive and expensive due to the need for proper sorting and cleaning. Additionally, many types of plastic can only be recycled once without acquiring defects and contaminants, and recycled materials may contain unwanted toxins. As such, there is a growing emphasis on developing better recyclable products, finding sustainable alternatives, and increasing the circularity of plastic products.

Plastic producers need to pay for the damage caused by plastic pollution
Plastic is everywhere. It is a cheap, versatile, and sterile material used in construction, home appliances, medical instruments, and food packaging. However, when plastic waste is not recycled, incinerated, or disposed of in sealed landfills, it becomes an environmental pollutant. The world produces around 350 million tons of plastic waste each year, and an estimated 1 to 2 million tons of plastic end up in our oceans annually. That's just 0.5% of plastic waste. However, this plastic waste affects wildlife, ecosystems, and even human health.
The true cost of plastic can be seen in the natural environment. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or non-existent. Even in parts of the developed world, plastic waste is ubiquitous, with organized waste management and recycling systems struggling to cope. Once in the ocean, it is difficult, if not impossible, to retrieve plastic waste. Mechanical systems can be effective at picking up large pieces of plastic from inland waters, but once plastics break down into microplastics, they are virtually impossible to recover.
Microplastics have been found in human livers, kidneys, and placentas, and the chemicals in plastic products can leach into tap water, potentially causing developmental, reproductive, neurological, and immune disorders. More than 1,500 species of marine and terrestrial animals are known to ingest plastics, with some tests confirming liver and cell damage and disruptions to reproductive systems. This damage, caused by the proliferation of plastic, should be accounted for by the producers.
To address plastic pollution, those who profit from its production must take responsibility for its negative impact. This includes investing in better waste management infrastructure, especially in poorer countries, and developing more recyclable and sustainable products. By increasing what ecologists call circularity, we can keep products in use for longer and find ways to reuse their materials. Plastic producers must be held accountable for the damage caused by plastic pollution and take an active role in mitigating its effects.

The world needs to reduce plastic production and increase circularity
Plastic is everywhere. It is cheap to make and profitable, but we are all paying the price. The world is facing a plastic crisis, and it is getting worse. The vast majority of plastic is not recycled, despite people's best efforts to put it in the correct bins. In fact, a Greenpeace report found that almost none of the plastic that people put into recycling bins is actually recycled. The United States, the world's largest plastic polluter, recyles only 5% of its household plastic waste. While the situation is slightly better globally, a shocking 91% of plastic waste is still incinerated, landfilled, or mismanaged.
The recycling system is deeply flawed. Most plastics are incompatible, making sorting costly and inefficient. Only a few types of plastic are widely recycled, and even these are not recycled at a high enough rate. For example, the recycling rate of PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3% in the same year. This is far below the 30% threshold needed to be considered "recyclable". The national average for recycling PET materials is 30%, but this could be much higher, as 100% of PET bottles can be recycled. In states such as Maine and Oregon, which have invested in recycling programs, up to 80% of PET bottles are recycled.
The problem is not just with the recycling system but also with plastic production. Plastic production is ramping up, and an even smaller percentage of it is being recycled. The industry plans to triple plastic production by 2050, which will only worsen the crisis. Plastic is also becoming more difficult to recycle due to the rise of flexible packaging. These lightweight packets for snacks and food are convenient but incredibly difficult to recycle due to contamination and complex composition.
To address this crisis, the world needs to reduce plastic production and increase circularity. Circularity refers to keeping products in use for as long as possible and finding ways to reuse materials. We need to develop better, more recyclable products and find sustainable alternatives. This will require a fundamental shift in our relationship with plastic, driven by policy and innovation. Local policies can make a huge difference in encouraging recycling, and global policymakers, innovators, and companies are paying renewed attention to these issues. Additionally, those who produce plastics need to be held accountable and pay for the damage plastic causes.

Plastic recycling is costly, time-consuming and rarely reaches 30%
Plastic recycling is a complex and costly process that involves multiple steps and high economic costs. The recycling journey of a plastic bottle exemplifies this complexity: after being discarded in a recycling bin, the bottle is sent to a collection facility where it is inspected for contaminants like rocks or glass. It is then washed, chopped into flakes, dried, melted into plastic lava, filtered for impurities, formed into strands, cooled, and finally chopped into pellets that can be sold on the market. This intricate process incurs significant expenses, including the costs of operating collection facilities, machinery, and labour.
The economic viability of plastic recycling is further challenged by the fluctuating costs of raw materials and recycling processes. The cost of producing plastics is closely tied to the cost of petroleum and natural gas, which have been on an upward trajectory. While recycling can offer cost advantages by utilising cheaper recycled pellets, the overall expense of the recycling process itself can be substantial. This is particularly true when considering the vast quantities of plastic waste generated annually, with billions of plastic water bottles produced and consumed in the United States alone.
The recycling rate for plastic, despite efforts and advancements, remains discouragingly low. According to reports, the recycling rate for post-consumer plastic was a mere 5% to 6% in 2021, falling far short of the 30% threshold required to be considered "recyclable" by standards set by initiatives like the Ellen MacArthur Foundation New Plastic Economy Initiative. This alarming disparity between the amount of plastic waste generated and the meagre recycling rate underscores the rarity of plastic recycling.
The challenges of plastic recycling extend beyond economic considerations. The process is incredibly time-consuming, requiring a lengthy journey from the recycling bin to its eventual transformation into something new. This journey involves multiple steps, including collection, inspection, washing, chopping, drying, melting, filtering, forming, cooling, and chopping into pellets. Each of these steps takes time and contributes to the overall time-consuming nature of the recycling process.
Furthermore, the sheer variety of plastics poses a significant obstacle to effective recycling. With thousands of different types of plastic in existence, the task of sorting and processing them becomes immensely difficult and costly. This complexity in sorting and the inability to melt different plastics together hinder the efficiency and feasibility of plastic recycling, contributing to the low recycling rates observed globally.
