Plastic pollution is one of the most critical environmental challenges of the 21st century. With only 9% of plastic being recycled, the rest ends up in landfills, litters landscapes, and pollutes our oceans. While recycled plastic is being used innovatively across industries, it is a highly contested topic, with some viewing it as a form of greenwashing. Recycling plastic can reduce energy consumption and emissions, conserve fossil fuels, and save water. However, it is susceptible to human error, with much recycled plastic still ending up in landfills. Additionally, the recycling process can release microplastics and toxic chemicals, impacting human, animal, and environmental health. To make plastic recycling truly sustainable, we need to scale up established technologies, develop solutions for hard-to-recycle plastics, and reduce single-use plastic production.

Recycling plastic reduces energy consumption and greenhouse gas emissions
Plastic is a significant contributor to climate change, emitting greenhouse gases at every stage of its life cycle. The production, incineration, and landfilling of plastics all have significant environmental impacts. However, recycling plastic offers a more sustainable alternative by reducing energy consumption and greenhouse gas emissions.
The process of extracting and refining fossil fuels to create plastic is highly energy-intensive and emits significant greenhouse gases. Recycling plastic reduces the need for virgin plastic production, which requires crude oil extraction and refining. This process is not only energy-intensive but also releases methane, a potent greenhouse gas. By using recycled plastic, we can cut down on the amount of crude oil extracted from the earth, reducing energy consumption and emissions associated with oil drilling and refining.
Recycling plastic also reduces the energy required to create new products. For example, using recycled plastic to make new bottles uses 75% less energy than creating bottles from virgin plastic. This reduction in energy consumption translates directly into lower greenhouse gas emissions. Additionally, recycling plastic saves water, as the extraction and manufacturing of virgin plastic materials have a high water footprint.
According to the Association of Plastic Recyclers (APR), using recycled plastic products reduces energy consumption and greenhouse gas emissions. A study by Argonne National Laboratory supports this claim, finding that advanced recycling of post-use plastic can reduce greenhouse gas emissions by 18% to 23% compared to crude oil-derived plastics. Furthermore, a 2018 study estimated that increasing the global recycling rate for plastic packaging from 14% to 70% would reduce CO2 emissions by 3.5 million tons per year.
The transition to a circular plastic economy is not just an environmental imperative but also an economic opportunity. By embracing recycled plastic, we can reduce energy consumption, lower greenhouse gas emissions, and move towards a more sustainable future.

Recycled plastic reduces the need for crude oil extraction
The use of recycled plastic is a highly contested topic in the world of sustainability. While recycled plastic is being used innovatively across industries, it is not without its faults. However, one of the main benefits of using recycled plastic is that it reduces the need for crude oil extraction.
Crude oil is a fossil fuel, and most plastic is derived from oil drilling and/or fracking. When we use recycled plastic, we can cut down on the amount of crude oil that needs to be extracted from the Earth. This is beneficial because the extraction of virgin raw materials has an incredibly high carbon footprint. Recycling plastic saves 3.8 barrels of crude oil for every ton of plastic recycled.
A 2018 study found that increasing the global recycling rate for plastic packaging from 14% to 70% would reduce CO2 emissions by 3.5 million tons per year. Additionally, recycling plastic reduces energy consumption. Recycling one ton of plastic saves 5,774 Kwh of energy, and using recycled plastic to make new bottles uses 75% less energy than creating bottles from virgin plastic.
The transition to a circular plastic economy is an environmental imperative that can also create economic opportunities. Over 500 organizations have signed the New Plastics Economy Global Commitment, pledging to increase recycled content in their packaging. However, it is important to note that the recycling process for plastic is not perfect, and there are concerns about the toxicity of recycled plastic.
Overall, while recycled plastic may not be a perfect solution, it can help reduce the need for crude oil extraction and contribute to a more sustainable future.

Recycling saves water
The process of extracting virgin raw materials, such as oil drilling and fracking, requires a large amount of water. Additionally, the manufacturing process for creating single-use items from these materials also consumes water. Recycling reduces the demand for these water-intensive processes, leading to a more sustainable water footprint.
While it is important to consider the water used in the recycling process itself, such as rinsing out containers, the impact is minimal compared to the water saved by reducing the need for virgin materials. Proper rinsing techniques, such as using dirty dishwater or composting food waste, can further minimize water usage during recycling.
The benefits of recycling extend beyond water savings. Recycling plastic specifically helps reduce the extraction of crude oil, lowers energy consumption, and cuts down on greenhouse gas emissions. Every ton of recycled plastic saves a significant amount of energy, oil, and landfill space.
The transition to a circular economy, where recycled materials are prioritized over virgin ones, is crucial for sustainability. By increasing recycling rates and embracing innovative solutions, we can significantly reduce the amount of plastic pollution in our oceans and contribute to a greener future.

Recycling rates need to be scaled up worldwide
While recycling rates have been increasing slowly in many regions, there is a need for a more rapid and collective shift towards embracing recycled plastic as a sustainable solution. This includes encouraging consumers to pay attention to sustainability and environmental responsibility in packaging, as well as businesses and governments taking action. For instance, over 500 organisations have signed the New Plastics Economy Global Commitment to increase recycled content in their packaging, and more than 60 countries have introduced bans and levies to curb single-use plastic waste.
Europe, led by Germany with a 56% recycling rate, does a better job than most other parts of the world when it comes to recycling. South Korea is also a notable example, with a recycling rate of approximately 53.7%. However, other countries, such as the United States, are lagging behind. The recycling rate in the US was only 4.5% by 2019, according to OECD data.
To scale up recycling rates worldwide, a combination of strategies and efforts from governments, businesses, and consumers is necessary. This includes implementing regulations and policies that promote recycling, investing in recycling infrastructure, and educating people about the importance of recycling and how to recycle properly. Additionally, supporting innovations like chemical recycling, which can increase plastic packaging recycling rates, is crucial.
By increasing recycling rates, we can reduce the amount of plastic waste that ends up in our oceans and landfills, mitigate the environmental and health risks associated with plastic pollution, and move towards a more sustainable and circular future.

Recycled plastic is a contested topic
Recycled plastic is a highly contested topic. While some view it as the most sustainable option, others see it as a form of greenwashing, where corporations appear more eco-friendly than they are. The debate centres on the environmental impact of recycled plastic, with proponents arguing for its potential to reduce waste and emissions, while critics highlight the challenges of human error, toxicity, and the dominance of corporate interests.
Proponents of recycled plastic highlight its potential to address the global waste crisis. Recycling plastic saves energy, crude oil, and landfill space. Every ton of recycled plastic saves 5,774 kWh of energy, 3.8 barrels of crude oil, and 30 cubic yards of landfill space. Increasing recycling rates can significantly reduce plastic pollution in the ocean. For every 1% increase in recycling rates, 1.5 million metric tons of plastic are kept from entering the ocean over 20 years. Additionally, recycled plastic is more cost-effective and eco-friendly than mining for metals or producing virgin plastic, which has a high carbon footprint due to oil drilling and fracking.
However, critics argue that the recycling process itself can be toxic and detrimental to the environment and human health. Greenpeace, for example, warns that recycling plastic can increase its toxicity due to the concentration of toxic chemicals, posing risks to humans, animals, and the environment. The breakdown of plastics during recycling can release microplastics and scatter microplastic pollution. Additionally, the recycling process is vulnerable to human error, with "wishcycling" (consumers recycling items without knowing if they are recyclable) leading to additional plastic waste.
The debate also extends to the role of corporations and governments. Over 500 organisations have pledged to increase recycled content in their packaging, and more than 60 countries have introduced bans and levies to curb single-use plastic waste. However, Greenpeace cautions against corporate interests driving the narrative of plastic recycling as the solution to the plastic pollution crisis. They advocate for significantly reducing plastic production and implementing global controls on chemicals in plastics.
While recycled plastic has the potential to contribute to sustainability, it is not a perfect solution. The challenge lies in balancing the environmental benefits of reduced resource extraction and emissions with the risks associated with the recycling process and the continued dominance of corporate interests in the plastic industry.
