Paper or plastic? That is the question. With growing environmental concerns, many companies are switching from plastic to paper packaging to become more sustainable. However, the answer to which is better for the environment is not so clear-cut. While paper is biodegradable and easier to recycle, its production can be more resource-intensive, requiring significantly more water and energy. Plastic, on the other hand, is derived from fossil fuels, lighter, and more durable, but it has contributed significantly to environmental damage due to improper disposal and its reliance on finite natural resources. So, when it comes to the strength of paper versus plastic, the answer lies not only in their physical properties but also in their environmental impacts and recyclability.

What You'll Learn
Paper is easier to recycle than plastic
Paper is also more widely recyclable, while plastic bags can take between 400 and 1,000 years to decompose. Paper bags require fewer reuses than bags for life to make them more environmentally friendly than single-use plastic bags. However, paper bags are less durable than other types of bags. So if customers have to replace their paper bags more frequently, it will have a greater environmental impact. The key to reducing the impact of all carrier bags is to reuse them as much as possible.
Recycling programs concentrate on printed paper and packaging. That's 86% of the paper we use versus only 41% of plastic. If every single plastic package were collected for recycling versus only half of the printed paper and paper packages, paper would still have a higher recycling rate. Paper is also the most recycled substance in the United States.
Paper is made from a renewable resource, can biodegrade, and is recyclable. However, scientific research shows just the opposite. Paper products take substantial amounts of energy to make, and paper and cardboard are the third-largest industry in energy use on the planet. Paper bags are anywhere between six to ten times heavier than lightweight plastic carrier bags and, as such, require more transport and associated costs. They would also take up more room in a landfill if they were not recycled.
Plastic bags generate 39% less greenhouse gas emissions than uncomposted paper bags and 68% less than composted paper bags. Plastic bags consume less than 6% of the water needed to make paper bags. It takes 1,004 gallons of water to produce 1,000 paper bags and 58 gallons of water to produce 1,500 plastic bags. Plastic grocery bags consume 71% less energy during production than paper bags.

Paper is biodegradable
While paper is biodegradable, its production can be more resource-intensive than that of plastic. For instance, cardboard production is water-intensive, generates emissions, and poses the risk of encouraging deforestation if not sourced sustainably. Paper is made from plant materials, and most plant materials are biodegradable. Biodegradable materials can be broken down naturally and safely in a short time, which is better for the environment and for us. Paper can be recycled up to 6 or 7 times before the paper fibres become too short for paper production, making it more sustainable than plastic.
However, paper's environmental impact can be higher than expected without sustainable sourcing or effective recycling systems. For example, paper recycling centres may not accept paper contaminated with food or other waste. Similarly, paper that is glossy or laminated may take longer to decompose due to added coatings or chemicals.
The environmental impact of paper if disposed of or littered is much less than that of plastic. Paper will naturally degrade and be absorbed harmlessly into the local ecosystem. On the other hand, plastic tends to poison the soil and anything around it. Biodegradable plastics are designed to degrade in landfills, but they will not break down any faster than regular plastic if littered in the open air or in the sea.
Many companies are switching to paper packaging instead of plastic to become more sustainable, especially with the new plastic tax regulations. However, biodegradable paper can only be made more eco-friendly if waste paper is recycled, and paper is sourced in a sustainable fashion.

Paper production is more resource-intensive
Paper production is the third largest industry user of energy on the planet. In comparison, plastic is lighter and more durable and less energy-intensive to manufacture. Traditional disposable plastic bags are produced from fossil fuels, but the total non-renewable energy consumed during their lifecycle is up to 36% less than paper bags.
The 2005 Scottish Report states that paper bags have a more adverse impact than plastic bags for most of the environmental issues considered. Paper bags scored particularly badly in terms of water consumption, atmospheric acidification, and eutrophication of water bodies. Paper bags are anywhere between six to ten times heavier than lightweight plastic carrier bags and, therefore, require more transport and associated costs.
Paper production also emits air pollution. According to certain studies, manufacturing paper emits 70% more pollution and 80% more greenhouse gases than the production of plastic bags. Paper production also results in 50 times more water pollutants than plastic bag production.

Plastic is lighter and more durable
Plastic is also more durable than paper. Plastic containers do not break easily when dropped or knocked over, unlike paper, which is more likely to split or tear, especially if the package gets wet. Plastic also protects vulnerable products from contamination or damage caused by moisture, humidity, gases, insects, microorganisms, and light.
However, it is important to note that plastic has attained a bad reputation for being detrimental to the environment. Plastic takes centuries to decompose and pollutes both land and oceans. On the other hand, paper is biodegradable and generally breaks down faster than plastic. Paper is also recyclable and is made from renewable resources.
While plastic may be lighter and more durable, the environmental impact of its disposal must be considered. The proper reuse and recycling of plastic containers can help reduce their environmental impact.

Paper promotes sustainable forestry
Plastic has contributed to significant environmental damage, particularly due to its improper disposal and reliance on fossil fuels. Many companies are now switching to paper packaging instead of plastic packaging to become more sustainable, especially with the new plastic tax coming into force. However, switching to paper also has its environmental issues. For example, cardboard production is water-intensive, generates emissions, and risks encouraging deforestation if not sourced sustainably.
Paper is biodegradable and generally breaks down faster than plastic. However, its production can be more resource-intensive. Paper is also easier to recycle, and some types of plastic cannot be recycled at all. Paper recycling is a simple and environmentally friendly process, whereas plastic recycling is volatile and produces a lower-quality product than the original.
Paper is a natural resource that is renewable, recyclable, and compostable. Paper is also the most recycled substance in the United States, with 65% of paper recycled compared to only 9% of plastic. Sustainable forestry, which paper promotes, balances harvesting with planting and ensures that forested habitats are not lost. Through sustainable forestry, trees are replanted, making them renewable.
The paper and wood products industry is a leader in promoting sustainable forest management. The American Forest & Paper Association (AF&PA) serves to advance public policies that foster economic growth, job creation, and global competitiveness. AF&PA members are committed to sustainable forest management and sourcing wood from responsibly managed forests. More than 1 billion trees are planted each year in the U.S., and one-third of the country is forested, totaling nearly 766 million acres.
Private landowners provide more than 90% of wood and paper products, which is essential to ensuring the long-term health of U.S. forests. Private foresters and family tree farms are incentivized to engage in smart, sustainable harvesting practices. Sustainable forests have recreational, aesthetic, and climate benefits. For example, forested lands are used for biking and hiking.
