Plastic is everywhere, and it's cheap to make and profitable. However, it is having a devastating impact on the environment. Despite the increase in recycling initiatives, less than 10% of plastic waste is recycled globally. Virgin plastic, which is made from fossil fuels, is cheaper and more prevalent due to the economic and infrastructural challenges of recycling. The process of recycling is complex, time-intensive, and expensive, and the resulting products are often of lower quality. This multi-step process involves sorting, cleaning, and reprocessing different plastic types to meet consistent quality standards, which incurs additional costs. The continuous production of virgin plastics poses a significant challenge to increasing recycling rates.

Less than 10% of plastic waste is recycled globally
Plastic is a significant contributor to global waste, and despite increasing recycling initiatives, less than 10% of plastic waste is recycled globally. This is due to a variety of factors, including the continued production and use of virgin plastics, the challenges of recycling, and issues with waste management.
Virgin plastics, which are new and pristine materials often used for manufacturing, have a competitive advantage over recycled plastics in terms of cost and consistency. They are made from fossil fuels, which are cheap and abundant, and have a sturdier molecular structure, making them ideal for precision manufacturing. However, the extraction and production of virgin plastics contribute to climate change through pollution and resource-intensive processes.
Recycling plastic, on the other hand, is complex and labour-intensive. It involves multiple steps, including sorting, cleaning, and reprocessing, which can be time-consuming and expensive. The quality of recycled plastics is often inconsistent, and they may contain toxins, making them unsuitable for certain applications. Additionally, the market for recycled plastics is limited, and they are generally more expensive than virgin plastics, hindering their broad market adoption.
The continuous production of virgin plastics poses a significant challenge to increasing recycling rates. Despite the environmental concerns, virgin plastics remain cheaper and more prevalent due to the economic and infrastructural challenges of recycling. This imbalance has long-term environmental impacts, as most single-use plastics end up in landfills, are incinerated, or pollute ecosystems instead of being recycled.
To address this issue, some countries have implemented regulations requiring the use of recycled plastics in the production of new products. There is also a drive to reduce reliance on virgin plastics by increasing the amount of post-consumer recycled content. However, these efforts are often not enough, and drastic cuts in the production of single-use plastics are needed to make a significant impact.

Virgin plastics are cheaper and more prevalent
Secondly, the process of creating virgin plastics gives them a competitive edge in terms of cost and consistency. Virgin plastic production begins with fossil fuel extraction, which is responsible for over 90% of the plastic in use today. This stage is resource-intensive and creates pollution that contributes to climate change. However, the subsequent availability of low-cost fossil fuels gives virgin plastics a pricing advantage over recycled plastics.
Additionally, the process of recycling plastic is complex and multi-step, requiring sorting, cleaning, and reprocessing to meet consistent quality standards. These additional steps incur costs, making recycled plastics more expensive than virgin plastics. The processing costs of poorly sorted or contaminated plastic loads can be particularly high, sometimes outweighing the profits from recycled materials. This issue is evident in projects that require extensive resources for sorting and purifying plastic waste, such as the Plastic Collective's initiatives in Indonesia and Ghana.
Furthermore, the continuous production of virgin plastics and the challenges associated with recycling contribute to an imbalance in the market. Even as recycling initiatives increase, less than 10% of plastic waste is recycled globally. The majority of single-use plastics bypass the recycling process, ending up in landfills, incineration, or polluting ecosystems. This imbalance poses a pressing issue with long-term environmental impacts, as it hinders the transition to a circular economy.
Lastly, the price trend for virgin plastics is on a downward path globally due to oversupply and declining prices. This trend further reinforces the prevalence and cost-effectiveness of virgin plastics compared to recycled alternatives. However, it is important to note that the adoption of a production cap on virgin plastics and the improvement in mechanical recycling technologies could spur a decrease in virgin plastic production and increase the adoption of recycled materials.

Recycling plastic is time-intensive and expensive
Despite the fact that all used plastic can theoretically be recycled, the reality is that recycling plastic is time-intensive, expensive, and often not economically viable.
The process of recycling plastic is complex and multi-stepped, requiring a significant amount of labour and resources. The plastic must first be sorted, cleaned, and reprocessed to meet consistent quality standards, which is a costly endeavour. For example, a project in Indonesia requires multiple sorting stages, followed by washing, crushing, de-watering, grinding, extrusion, and pelletisation. These extensive processes make recycled plastic more expensive than virgin plastic, which is made from cheap fossil fuels.
The high cost of recycling plastic can be attributed to the various steps involved in the process. The plastic must be collected, sorted, washed, chopped, dried, melted, filtered, formed into strands, cooled, and finally chopped again into pellets that can be sold. Each of these steps incurs costs, and the final product is often of lower quality than virgin plastic.
Additionally, the market for recycled plastic is limited due to its unpredictable and suboptimal additive combinations, as well as the degradation of quality that occurs with each cycle of recycling. This means that recycled plastic can only be reused a few times before it becomes unusable, further increasing the cost of recycling.
The economic challenges of recycling are further exacerbated by the low cost of virgin plastic. The cost of using oil to produce virgin plastic is extremely low, making it difficult to justify the higher cost of recycling plastic waste. This has led to a situation where, despite increasing recycling initiatives, less than 10% of plastic waste is recycled globally, with the majority of single-use plastics ending up in landfills, being incinerated, or polluting ecosystems.
However, it is important to note that the cost-effectiveness of recycling should not be solely based on financial profit. Recycling has numerous environmental and social benefits, such as reducing carbon footprints and creating jobs. As technology and infrastructure develop, the price of recycling is likely to decrease, making it more economically viable in the future.

Plastic waste often ends up in landfills or oceans
Despite global recycling initiatives, less than 10% of plastic waste is recycled worldwide. Virgin plastics, which are made from fossil fuels, are cheaper and more prevalent due to the economic and infrastructural challenges of recycling. This imbalance has severe environmental implications, as the majority of single-use plastics bypass recycling and end up in landfills, are incinerated, or pollute ecosystems and oceans.
Rejected recycling due to contamination is another factor contributing to plastic waste. Non-recyclable items and food waste can contaminate plastic loads, making them unsuitable for recycling. In some cases, it is more economically feasible to divert contaminated loads to landfills, further increasing plastic waste. Additionally, incineration of plastic waste, while reducing landfill volume, contributes to climate change and environmental pollution.
Careless and improper waste disposal significantly contribute to plastic waste in oceans. When plastic is thrown away, it can be blown away during transport to landfills and eventually clutter around drains, rivers, and seas. Litter dropped on streets is also carried by rainwater and wind into waterways, ultimately reaching the oceans. Microfibres from washing machines and flushed items like wet wipes and sanitary products further add to the plastic surge in oceans.
The mismanagement of plastic waste is a critical factor in plastic pollution. Mismanaged waste is not recycled, incinerated, or stored in sealed landfills, making it vulnerable to environmental leakage. This mismanagement is more prevalent in low-to-middle-income countries with inadequate waste management infrastructure. As a result, most plastic emissions come from middle-income countries, particularly in Asia.

The continuous production of virgin plastics impacts recycling rates
The continuous production of virgin plastics poses a significant challenge to increasing recycling rates. Virgin plastics are new and pristine materials, often used for manufacturing plastic products such as films and packages. They are produced directly from fossil fuels, which are relatively inexpensive, giving them a competitive edge in cost and consistency. This is particularly important for industries requiring reliable quality in packaging, electronics, and more.
On the other hand, recycling plastic is a complex, multi-step process that is both labour- and resource-intensive. Sorting, cleaning, and reprocessing different plastic types to meet consistent quality standards incurs additional costs. The rate of 'rejected recycling' due to contamination can be high, and even some plastic intended for recycling ends up in landfills. These factors make recycled plastics more expensive than virgin materials, creating a significant hurdle in their broad market adoption.
The global increase in plastic production, from 2 million tonnes in 1950 to over 400 million tonnes in 2021, has created a crisis. Despite increasing recycling initiatives, less than 10% of plastic waste is recycled globally, with the majority of single-use plastics bypassing the recycling process. The low demand for recycled plastics, coupled with the dominance of virgin plastics, undermines efforts towards sustainability and contributes to long-term environmental impacts.
To address this issue, some countries have implemented regulations mandating a minimum percentage of recycled plastic in new products, creating a built-in demand for recycled materials. For example, California has legislation requiring specific recycled content in plastic products. Additionally, community-based recycling models, such as those empowering female entrepreneurs in waste collection and processing, have shown potential for impactful change. However, scaling these initiatives to a global level requires broader support and systemic change.
