Paper bags are biodegradable, but plastic is non-biodegradable
Paper bags are biodegradable, addressing the concerns of consumers who are increasingly engaged in conversations about plastic and the litter problems it causes. However, plastic is non-biodegradable and can take between 400 and 1,000 years to decompose. This means that discarded and littered plastics can become a near-permanent part of the landscape.
Paper bags are also recyclable, and recycling paper is a simple process that does not rely on chemical reactions. Paper is the most recycled substance in the United States, and paper recycling rates consistently outrank those of plastic. In the US, 65% of paper is recycled, compared to only 9% of plastic.
However, the production of paper bags is more energy-intensive than that of plastic bags. Paper bags require more energy and resources to manufacture and transport, which can result in a larger carbon footprint. They are also less durable than plastic bags and may need to be replaced more frequently, increasing their environmental impact.
The choice between paper and plastic bags depends on personal preference and the specific situation. While paper bags are biodegradable and recyclable, their production and transportation can have a significant environmental impact. On the other hand, plastic bags are more energy-efficient to produce and transport, but they are non-biodegradable and challenging to recycle.
To reduce the environmental impact of carrier bags, the key is to reuse them as much as possible, regardless of the material they are made of. Reusable plastic bags, for example, become a more environmentally friendly option after four or more uses. Ultimately, the most eco-friendly option may be to use alternative bags such as backpacks or cloth bags that can be reused multiple times.

Paper is made from renewable resources, but plastic is not
Paper is made from trees, which are a renewable resource, whereas plastic is derived from fossil fuels, which are non-renewable. This is one of the reasons why many people believe paper bags are more environmentally friendly than plastic bags. However, the process of making paper requires a significant amount of energy, with some estimates suggesting that manufacturing 1,000 paper bags requires 3.4 times more energy than traditional plastic bags. Paper bags also weigh more than plastic bags, which means that transporting them requires more energy, further adding to their carbon footprint.
The Northern Ireland Assembly reported in 2011 that it "takes more than four times as much energy to manufacture a paper bag" compared to a plastic bag. The report also noted that paper bags are produced from forests, requiring the cutting down of trees, whereas plastic bags are made from the waste products of oil refining. The manufacturing process for paper bags also produces a higher concentration of toxic chemicals compared to single-use plastic bags.
Paper bags are more widely recyclable than plastic bags, and paper is the most recycled substance in the United States. Plastic bags can take between 400 and 1,000 years to decompose, whereas paper bags are biodegradable and can be recycled. However, paper bags are less durable than plastic bags and may need to be replaced more frequently, which can have a greater environmental impact.
The key to reducing the impact of carrier bags, regardless of their material, is to reuse them as much as possible. While paper bags are generally considered more environmentally friendly due to their renewability, recyclability, and biodegradability, they also have their downsides in terms of energy consumption and durability. Ultimately, the choice between paper and plastic bags depends on personal preference, the specific situation, and the ability to reuse and recycle the bags responsibly.

Paper is easier to recycle, but plastic recycling is time-consuming and costly
Paper bags are more widely recyclable than plastic bags, which can take between 400 and 1,000 years to decompose. However, paper bags are not as durable as plastic bags and may need to be replaced more frequently, increasing their environmental impact. Paper bags also require more energy and resources to manufacture and transport, resulting in a larger carbon footprint.
The recycling process for paper is simple and environmentally friendly. Paper is easy to repulp and can be turned into a 100% recycled paper product. Across the globe, the recycling rates for paper consistently outrank those for plastic. In the US, 65% of paper is recycled, compared to only 9% of plastic.
On the other hand, plastic recycling is a volatile process that produces lower-quality plastic than the original product. Unstable plastic resin can break the machinery used for recycling, and the recycled product must often be mixed with new plastics to create a usable final product. After two to three rounds of recycling, plastic can no longer be remade into a reusable material.
Additionally, the complexity of recycling plastic has led to a decrease in plastic recycling rates in some countries. Plastic recycling is time-consuming and costly, and certain types of plastic cannot be recycled at all. The process depends on the availability of specific machinery at recycling centres, and with seven different types of plastic, efficient sorting can be challenging.
While paper bags are more recyclable, the manufacturing process requires a significant amount of energy and resources. Paper production involves the harvesting of trees, resulting in fewer trees to absorb greenhouse gases. It also generates up to seven times more solid waste and consumes 25–3.5 times more water than plastic production. Therefore, when considering the environmental impact of paper vs. plastic, it is essential to look at the bigger picture, including manufacturing, transportation, and recycling.

Paper bags are less durable and may need to be replaced more often
Paper bags are less durable than plastic bags and are more likely to tear, especially if they get wet. This means that paper bags may need to be replaced more often, which could have a greater environmental impact. The key to reducing the environmental impact of carrier bags is to reuse them as much as possible.
The Environment Agency found that a paper bag needs to be reused at least three times to be considered environmentally friendly, compared to four times for a plastic bag. However, the Agency concluded that it is unlikely that a paper bag can be regularly reused the required number of times due to its low durability.
The durability of paper bags is particularly important when considering their environmental impact, as paper bags require more energy and resources to manufacture and transport than plastic bags. Paper bags are heavier than plastic bags, so transporting them requires more energy, adding to their carbon footprint.
Additionally, the process of making paper bags requires a large amount of energy and resources. Paper bags are made from trees, which are a renewable resource, but harvesting trees means there are fewer trees to absorb greenhouse gases. Paper production also uses significantly more water than plastic bag production and produces more solid waste.
While paper bags are less durable and may need to be replaced more often, it is important to consider the entire lifecycle of a bag when comparing the environmental impact of paper and plastic bags. Proper waste management and recycling practices can also play a significant role in reducing the environmental impact of both paper and plastic bags.

Plastic bags are produced from waste products of oil refining, paper requires forests to be cut down
Plastic bags are produced from the waste products of oil refining. Crude oil is extracted from underground and transported to the shore via tankers. It is then pumped through pipelines to an oil refinery, where it undergoes a refining process to transform it into different petroleum products. This process yields useful chemicals, including monomers, which are the basic building blocks of polymers. The monomers comprise double bonds, allowing carbon atoms to react and form polymers.
The production of plastic bags is linked to the use of petroleum. About 8% to 10% of our total oil supply is used to make plastic, with an estimated 12 million barrels of oil used annually in the US alone for plastic bag production. This equates to a significant amount of fuel, highlighting the environmental impact of plastic bag manufacturing.
On the other hand, paper bags require forests to be cut down. The demand for paper has led to a gradual increase in deforestation, resulting in the cutting down of 4 to 8 billion trees annually. Approximately 405 million tonnes of paper and paperboard are produced, accounting for around 13% to 15% of total wood consumption. The paper industry is a significant contributor to energy consumption and has a notable environmental impact due to its water usage and the release of stored carbon dioxide when trees are cut down.
The manufacturing process for paper bags also produces a higher concentration of toxic chemicals compared to single-use plastic bags. Additionally, paper bags require more energy and resources for manufacturing and transportation, resulting in a larger carbon footprint. However, paper bags are biodegradable and more widely recyclable than plastic bags, which can take between 400 and 1,000 years to decompose.
While plastic bags are made from waste products, they contribute to the demand for oil and have a long-lasting environmental impact due to their slow decomposition. Paper bags, despite their recyclable nature, also contribute to deforestation and have a higher initial environmental cost in terms of energy and resource usage during production and transportation. Ultimately, the choice between plastic and paper bags depends on various factors, including personal preference, durability, and responsible waste management practices.
