While the majority of Americans believe that plastic waste is a serious problem requiring immediate political action, some practical challenges need to be addressed to reduce our reliance on plastic. Plastic is an inevitable part of consumer behaviour, and it is difficult to cut out completely. Plastic packaging supports the safe distribution of food over long distances, minimises food waste, and provides a barrier against bacteria. It is also challenging to recycle because there are seven types of plastic, and contamination and mixing of polymer types can lower the economic and technical value of the secondary plastic being made. Furthermore, companies that use plastics have a pivotal role in changing this unsustainable dynamic, and they are responding to public pressure to address the plastics problem. However, some companies are investing in risky emerging chemical conversion recycling technologies that offer false hope and lock in demand for plastic packaging.

Plastic packaging supports food safety and reduces food waste
Plastic packaging has been a topic of debate, with many companies facing pressure to address their plastic pollution. However, plastic packaging plays a crucial role in food safety and waste reduction, which are essential aspects of modern life.
Plastic packaging is instrumental in ensuring food safety during transportation, storage, and at the point of sale. Its inert and non-toxic nature prevents contamination by acting as a barrier against bacteria. This helps preserve the taste, nutritional value, and physical properties of food, keeping it fresher for longer. For example, plastic film wrapping a cucumber can extend its shelf life from three to 14 days, while selling grapes in plastic bags or trays has reduced in-store wastage by 20%.
The lightweight and durable nature of plastic packaging also contributes to sustainability and cost reduction. Lighter shipments increase fuel efficiency, reducing the environmental impact and costs associated with transportation. Additionally, plastic packaging is more affordable than alternatives like glass or aluminum, making food more accessible and economical for consumers, especially in rural areas and food deserts.
While plastic pollution is a pressing issue, it is important to recognize the benefits of plastic packaging in food safety and waste reduction. However, this should not detract from the need to address plastic waste. To mitigate the negative impacts, companies and researchers are exploring innovative solutions, such as compostable materials, biodegradable packaging, and improved recycling technologies. These efforts aim to balance the benefits of plastic packaging with environmental sustainability, ensuring that plastic waste does not end up in nature.

Plastic is inevitable due to consumer behaviour and convenience
Plastic is an inevitable part of consumer behaviour, and the plastic waste problem has become a mainstream part of public consciousness. The packaging sector is responsible for almost half of the plastic in the world, and plastic packaging supports the safe distribution of food over long distances, minimising food waste by keeping food fresher for longer. For example, 1.5g of plastic film wrapping a cucumber can extend its shelf life from three to 14 days, and selling grapes in plastic bags or trays has reduced in-store wastage by 20%.
However, 40% (or 9 million tonnes) of all food packaging ends up in landfills. The current waste management system and recycling infrastructure cannot properly manage the volume of virgin plastic. Only 8.7% of plastic waste in the US is recycled, and globally, only 9% is ever recycled, with only one-tenth of that amount recycled more than once in the last 50 years.
The reality is that reusable bags would have to be used 3000 times to neutralise the carbon footprint of a disposable bag. In the age of convenience, it is not that simple to rely less on plastic. Plastic packaging cannot be recycled infinitely because it degrades in quality, and contamination and mixing of polymer types can lower the economic and technical value of the secondary plastic being produced.
To reduce plastic waste, companies need to rethink how products are delivered to consumers and invest significantly in reusable and refillable delivery systems. However, companies are investing in risky emerging chemical conversion "recycling" technologies, which offer false hope and lock in demand for plastic packaging. They are also obscuring the true impacts of packaging behind confusing marketing terms, sustainability language, and industry alliances, hoping that consumers will continue to believe the false promise that plastic can be improved.

Plastic production is projected to increase, so reducing it is counter-intuitive
Plastic is an inevitable part of consumer behaviour, and it is deeply embedded in our daily lives. Plastic packaging, for example, supports the safe distribution of food over long distances, minimises food waste by keeping food fresher for longer, and provides a barrier against bacteria. A 2020 report by Earth.org illustrates this with the example of 1.5g of plastic film wrapping a cucumber, which extends its shelf life from three to 14 days. Similarly, selling grapes in plastic bags or trays has reduced in-store wastage by 20%.
However, the problem of plastic waste is a serious one, with plastic waste flowing into nature at an alarming rate. In the US alone, the annual volume of plastic waste produced is over 42 million metric tons, with only 8.7% of it recycled. The rest ends up in landfills or the environment, polluting the air, water, and soil that both people and nature need to survive.
Despite the growing public awareness and concern about the plastic pollution crisis, plastic production is projected to increase in the coming years. Between 1950 and 2017, global plastic production increased 174-fold, and it is expected to double by 2040. This is largely due to fossil fuel companies investing billions of dollars in building new plastic-making factories in the United States. As a result, plastic production is forecast to grow by 40% in the next decade.
This projected increase in plastic production presents a challenge to efforts to reduce plastic waste. While some companies have made commitments to reduce plastic pollution and improve recyclability, these efforts may not be enough to keep up with the increasing production. For instance, while Nestlé has pledged to make all its plastic packaging 100% recyclable or reusable by 2025, it is one of the companies that profit from single-use models and continues to expand its plastic use.
Therefore, to effectively address the plastic pollution crisis, a multi-faceted approach is needed. Companies must rethink how products are delivered to consumers and invest significantly in reusable and refillable delivery systems, as well as alternative materials and technologies. At the same time, regulation will play a crucial role, with producers being held accountable for the materials they use and encouraged to design products with the end of life in mind.

Recycling is not enough; companies must rethink product cycles
Plastic is an inevitable part of consumer behaviour, and the plastic waste problem has become a mainstream part of the public consciousness. While recycling is a step in the right direction, it is not enough to solve the plastic crisis. Companies must rethink their product cycles and embrace innovative solutions to address this issue effectively.
Recycling has become second nature for many people, reflecting a shared commitment to cleaner communities and a healthier planet. However, the current waste management systems and recycling infrastructure struggle to keep up with the volume of plastic waste. In the US, only 8.7% of the annual volume of plastic waste, estimated at over 42 million metric tons, is recycled. The recycling process also faces challenges due to the various types of plastic, contamination, and the degradation of plastic quality over multiple uses.
To truly tackle the plastic crisis, companies must go beyond recycling and focus on reimagining their product cycles. This involves shifting attention to the front of the process and exploring fundamentally different flows of materials to meet consumer needs. Compostable materials, such as seaweed-based packaging, offer promising alternatives to traditional plastics, with the added benefit of carbon sequestration.
Additionally, companies should prioritise reuse and refillable delivery systems. For example, start-ups like Loop, a supermarket delivery service using only reusable containers, are gaining momentum. By embracing reusable solutions, companies can reduce their reliance on single-use plastics and contribute to a more sustainable future.
While some companies have made voluntary commitments to reduce plastic pollution, public pressure and regulatory action are crucial in driving systemic change. Consumers are increasingly voting with their feet, favouring businesses that address their plastic usage. Regulatory initiatives, such as Extended Producer Responsibility measures, aim to hold companies accountable for reducing their plastic footprint and promoting sustainable alternatives.

Plastic alternatives may harm the planet in other ways
In addition, most plant-based plastics are identical to their fossil-fuel-based counterparts on a molecular level, and last just as long in the environment. Other substitutes require many of the same toxic chemical additives as conventional plastics to keep them waterproof, flexible, durable, and colorfast.
Furthermore, the production of bioplastics is limited in scale and more expensive than conventional plastic. There is not enough global supply of alternative materials to replace the amount of single-use plastic being produced today.
Finally, it is important to note that plastic alternatives are not a perfect solution to the problem of plastic pollution. They are a start, but alone will not be enough. The root of the problem, our throwaway society, must be addressed.
