The choice between paper and plastic bags has been a long-standing debate. Plastic bags are cheaper to produce and buy, and are generally more durable and produce less pollution during manufacturing. However, they are non-biodegradable and pose a threat to marine life. Paper bags, on the other hand, are biodegradable and recyclable, but they cost more and require more energy to manufacture and recycle. They also take up more space in landfills and contribute to greenhouse gas emissions. With the environmental concerns surrounding plastic bags, some countries have banned or taxed their use, leading to a resurgence in paper bag usage. This discussion weighs the costs and benefits of each material, considering economic and environmental factors, to determine which option is more costly.
| Characteristics | Values |
|---|---|
| Cost of production | Plastic bags are cheaper to produce. A standard plastic grocery bag costs about a penny to produce, while a paper bag costs 4 to 5 cents. |
| Environmental impact | Plastic bags require 50% less energy to produce and cause less pollution during manufacturing. Paper bags are made from trees, a renewable resource, but their production generates more air and water pollution. Paper bags are recycled more often but take up more space in landfills, where they are slow to degrade. Plastic bags are made from non-renewable resources and are non-biodegradable, but they can be recycled and take up less space in landfills. |
| Consumer preference | Paper bags are seeing a resurgence, particularly at upscale grocers. However, reusable bags are touted as the best alternative to disposable bags. |
| Government regulations | Some countries and cities have banned or taxed plastic bags to discourage their use, including San Francisco, Bangladesh, and Bhutan. |

What You'll Learn
Plastic bags are cheaper to produce and buy
The production of paper bags generates significantly more air and water pollution, and manufacturing and recycling them requires more energy than plastic bags. Paper bags are also more expensive to recycle than plastic bags, and they have a limited recyclable lifespan as the fibres break down too much after continued re-pulping.
The higher cost of paper bags is reflected in the price that stores pay for bags, which represents the direct cost involved in production. As a result, most grocery stores and retail businesses do not use 100% recycled paper bags.
While plastic bags are cheaper, they are non-biodegradable and are made from crude oil and natural gas, both non-renewable resources. They have been banned or taxed in several countries to discourage their use. However, the Natural Resources Defense Council still recommends plastic bags to everyone unable to use a reusable bag, citing the environmental impact of paper bags.

Paper bags cost more and use more energy to manufacture
Plastic bags are cheaper to produce and buy, and are generally less than a cent per bag. According to the plastics industry, a standard plastic bag costs about a penny to produce, whereas paper bags cost between 4 and 5 cents. Paper bags are also larger and heavier, with a paper bag weighing almost a quarter of a pound, compared to a plastic bag weighing two-tenths of an ounce. This means that more paper is required to produce a single bag, and the manufacturing process requires more energy.
Paper bags are made from trees, a renewable resource, but the production process generates significantly more air and water pollution. They are also recycled more often, but they take up more space in landfills and are slow to degrade. Paper also has a limited recyclable lifespan as the fibres break down too much after continued re-pulping.
Plastic bags, on the other hand, are made from crude oil and natural gas, both non-renewable resources. They are non-biodegradable but can be recycled, although they are often simply discarded. Plastic bags are also easily blown about, meaning they often end up as litter and can endanger marine animals.
Despite the environmental concerns around plastic bags, on most counts, they come out ahead in terms of cost and convenience. The Natural Resources Defense Council recommends plastic bags to everyone unable to use a reusable bag, and paper bags only for those living on the coasts to protect marine wildlife.
However, it is worth noting that the true cost of plastic bags may be higher than it seems. Plastic bags do not "down-cycle", meaning that they can be recycled into new plastic bags indefinitely, whereas paper can be recycled into fillers and lower-grade materials at the end of its recyclable life. Additionally, as more local governments require compostable plastic bags, the cost of these bags will likely drop, making them a more affordable option.

Plastic bags require 50% less energy to produce
The Natural Resources Defense Council recommends plastic bags to those who are unable to use reusable bags and suggests paper bags only for those living in coastal areas to protect marine wildlife. Plastic bags are also recommended because they take up 90% less space in landfills, where over 85% of paper bags and 97% of plastic bags end up. However, plastic bags are criticized for endangering marine animals and for being easily blown away, often ending up as litter.
While plastic bags may require less energy to produce, they are not without their environmental concerns. To discourage the use of disposable plastic bags, some countries have implemented bans or taxes on plastic bags. For example, San Francisco has recently approved measures to reduce plastic bag use, and California has proposed a mandatory charge for plastic bags.
On the other hand, paper bags are seeing a resurgence, with some upscale grocers, such as Trader Joe's, adopting them as their standard bags. Paper bags are also recycled more often than plastic bags, although it is important to note that neither type of bag biodegrades in modern landfills, which are managed for stability rather than decomposition.
Overall, the debate between paper and plastic bags is complex, and there are valid arguments and concerns on both sides. While plastic bags may require less energy to produce, other factors such as recycling rates, environmental impact, and consumer preferences must also be considered when determining the true cost of these bags.

Paper bags are recycled more often but take up more space in landfills
Plastic bags have been a topic of debate for a while now, with many countries banning or taxing them to discourage their use. The main argument in favour of this is that plastic bags contribute to litter, garbage in landfills, ocean pollution, and harm to marine life. Paper bags are often considered a more environmentally friendly alternative. However, paper bags are six to ten times heavier than plastic bags, requiring more fuel and transportation costs. They also take up more space in landfills.
Paper bags are recycled more often than plastic bags, but they still have a greater per-bag impact on landfills. This is because they are bigger and bulkier. The recycling process for paper also involves multiple steps, each requiring huge machines and intensive energy use, which rely on fossil fuels. Paper bags are made from trees, a natural resource that is otherwise carbon-fixing. The production of paper bags thus adds waste to the world and kills one of our greatest tools for fighting pollution.
The production of paper bags consumes vast amounts of water and energy, leading to higher carbon emissions and environmental degradation. It takes four times as much energy to manufacture a paper bag compared to a plastic bag. Paper bags also generate 70% more air pollutants and 50 times more water pollutants than plastic bags. However, paper bags are biodegradable and easier to recycle than plastic bags.
The environmental impact of paper bags can be mitigated if they are reused multiple times. Reusable bags, in general, can significantly reduce waste if used consistently and properly cared for. Cotton bags, for example, are made from a renewable resource and are biodegradable, strong, and durable. However, the production of cotton bags requires water, pesticides, and fertilisers, and if not reused enough, can result in a larger carbon footprint than single-use plastic bags.
In summary, while paper bags are recycled more often, they take up more space in landfills and have a greater per-bag impact. The environmental impact of paper bags is further exacerbated by their production and recycling processes, which consume more resources and energy. Reusable bags are a better alternative to both paper and plastic bags if they are used consistently and properly.

Plastic bags are non-biodegradable and endanger marine life
Plastic bags are non-biodegradable and pose a significant threat to marine life. They are often ingested by marine animals, leading to fatal consequences. Turtles, for example, frequently mistake plastic bags for their natural prey, jellyfish, and can ultimately starve due to a false sense of fullness. This issue extends to other marine creatures as well, including whales, dolphins, and porpoises, who may also become entangled in plastic debris.
The impact of plastic pollution on marine life is devastating and widespread. An estimated 300,000 whales, dolphins, and porpoises die annually from entanglement in ghost gear, which includes abandoned fishing nets and other plastic debris. Plastic ingestion is also a critical issue, with a whale found in 2019 having ingested 40kg of plastic, primarily plastic bags. This ingestion of plastic can lead to severe inflammation of abdominal tissues and intestinal injuries, causing immense suffering and death.
Seals and other marine mammals are also at risk from plastic bags. When filled with water, these bags can closely resemble the prey of these marine creatures, such as squid. As a result, they may inadvertently consume plastic, leading to health complications and mortality. This problem is not limited to large marine animals, as fish in the North Pacific ingest a substantial amount of plastic each year, transferring it up the food chain to larger fish, marine mammals, and eventually humans through seafood consumption.
The presence of plastic bags and other plastic debris in the oceans is a pressing issue that endangers marine life. While paper bags may be recycled more frequently, plastic bags are recommended by organizations like the Natural Resources Defense Council for those who cannot use reusable bags. This recommendation is based on the reduced environmental impact of plastic bags during production, requiring 50% less energy and causing less pollution. However, the critical task is to prioritize reusable bags over disposable options to minimize the overall environmental footprint.

Frequently asked questions
Plastic is generally cheaper to produce than paper due to lower material costs and more efficient production processes. Paper production requires a lot of energy and raw materials, which can make it pricier.
Paper packaging is bulkier and heavier than plastic, which increases transportation and storage costs. Paper is also more susceptible to moisture, mould and water, limiting its use and requiring careful storage.
Paper is generally considered more environmentally friendly than plastic because it is made from renewable resources and is biodegradable. However, paper production requires a lot of energy and water, and harvesting trees means fewer trees are available to absorb greenhouse gases. Plastic has a long degradation process and relies on non-renewable resources for production, but it is lightweight and durable.
