Printed Books: Pollution Or Progress?

The debate between the environmental impact of printed books and e-books has been ongoing for years. With the rise of technology, many people are switching to e-books, which can store thousands of books in one device. However, the production of e-readers also requires many natural resources and contributes to electronic waste. On the other hand, the publishing industry is one of the leading contributors to air pollution, with paper mills releasing carbon dioxide, carbon monoxide, and nitrogen oxides into the environment. So, do printed books cause pollution?

The carbon footprint of printed books

The environmental impact of printed books is a complex issue that depends on various factors, including the sources of paper and the printing process. While it is challenging to quantify the exact carbon footprint of printed books, there are several considerations to be made regarding their production, use, and disposal.

Firstly, the production of printed books involves the consumption of natural resources, such as trees and water. According to estimates, the publishing industry in the United States emits over 40 million tons of carbon dioxide and cuts down 32 million trees annually. Additionally, the printing industry uses about 8 liters of water per book and pollutes approximately 600 million cubic meters of water annually due to the use of toxic substances in the bleaching, coloring, and binding processes.

The use of paper in printed books has a significant environmental impact. Paper production often poses risks to old-growth forests, and the publishing industry's demand for paper contributes to deforestation. Deforestation not only disrupts ecosystems and biodiversity but also releases carbon dioxide and other greenhouse gases into the atmosphere as trees are cut down. Furthermore, the ink used in printing can release volatile organic compounds, contributing to smog and asthma aggravation.

The disposal of printed books is another factor contributing to their carbon footprint. When printed books are discarded and end up in landfills, they can release additional greenhouse gases as they decompose. This is particularly concerning given the significant number of books that are printed but never sold or are thrown away instead of recycled.

However, it is important to note that the carbon footprint of printed books is not just limited to their production and disposal. The transportation and storage of printed books also contribute to their environmental impact, as fuel is required to transport physical books to retailers and consumers.

In conclusion, while printed books do have a carbon footprint, the impact varies depending on the specific practices and sources used in their production, distribution, and end-of-life management. It is crucial to consider the entire lifecycle of a printed book to accurately assess its environmental impact and make informed decisions about the sustainability of this medium.

The environmental impact of paper production

The paper industry's impact on forests and trees is a major concern. While the industry often uses trees from working forests, which are continuously replanted, the act of cutting down trees disrupts ecosystems and releases carbon dioxide and other greenhouse gases into the atmosphere. It is estimated that it takes one entire tree to print just 25 books, and the US publishing industry alone cuts down 32 million trees a year. Greenpeace recommends that publishers replace virgin fiber with 100% post-consumer recycled paper to reduce their carbon footprint.

Water is also an essential part of the papermaking process, and the industry has been criticized for its water management practices. The printing industry consumes large amounts of water, with about 8 liters used per printed book. The industry is responsible for polluting about 600 million cubic meters of water per year due to the use of toxic substances in the paper bleaching, coloring, and binding processes. However, the US paper industry is taking steps to improve its water management, with members continuously innovating to reduce and reuse water.

The paper industry also contributes to air pollution, particularly through the release of greenhouse gases. The global print and paper industry accounts for about 1% of global carbon dioxide emissions, with emissions generated from fossil fuel combustion, wastewater treatment, purchased power, and transportation. The industry has taken steps to reduce its greenhouse gas emissions, with AF&PA members in the US committing to reducing emissions by 50% by 2030.

In addition to these direct environmental impacts, the paper industry also generates significant waste. Paper and paperboard make up a large proportion of solid municipal waste, and the industry has been criticized for its high level of consumption and waste. The rise of modern technology, such as the printing press, has made disposable paper a cheap and widely consumed commodity. However, efforts are being made to address this issue, with some publishers prioritizing printing only the amount of books that will be used and focusing on recycling and sustainability initiatives.

E-readers vs. printed books

The debate between e-readers and printed books is a complex one, with valid arguments on both sides.

Printed books consume natural resources and use toxic substances. The publishing industry cuts down millions of trees each year, with one source estimating 32 million, and uses large amounts of water (about 8 litres per book). The industry also pollutes water with the toxic substances used to bleach paper, colour it with ink, and bind pages. However, in recent years, a significant portion of the paper used comes from trees grown specifically for paper, and when these are cut down, new ones are planted.

On the other hand, e-readers also consume natural resources and produce waste. E-readers require rare elements such as cobalt and tantalum, and one source estimates that producing an e-reader uses 40 times more water than producing a printed book. E-readers also contribute to electronic waste, which is toxic and pollutes the environment. However, one e-reader can be used to read thousands of books, reducing the need for continually producing new books.

The environmental impact of each option depends on individual reading habits. E-readers have a higher carbon footprint than a single book, but if a prolific reader uses an e-reader for many years, they can significantly reduce their carbon footprint. The production, transportation, and storage of both books and e-readers also contribute to their environmental impact.

Digital reading is on the rise, with e-readers projected to make up 75% of the total market by 2025. However, print is still the most popular format, with 51% of total book sales coming from paperback purchases in the first half of 2021. Publishers are also rethinking book design, with certain fonts using less ink and paper, and offering recycling programs for old devices.

In conclusion, there is no clear winner in the debate between e-readers and printed books. Both options have environmental consequences, and the most sustainable choice depends on individual reading habits and preferences.

The waste produced by the publishing industry

The publishing industry produces a significant amount of waste, with the US publishing industry alone emitting over 40 million tons of carbon dioxide and cutting down 32 million trees annually. The environmental impact of the industry extends beyond the cutting down of trees, as the printing process consumes large amounts of water (approximately 8 litres per book) and pollutes water sources with toxic substances used for bleaching, colouring, and binding. This results in the pollution of about 600 million cubic meters of water annually.

The issue of waste in the publishing industry is further exacerbated by the number of books that go unsold or are thrown away. It is estimated that 640,000 tons of books, equivalent to around 320 million books, are discarded each year. This contributes to the growing problem of paper waste, which accounts for 26% of landfill waste worldwide. The production of unread books also leads to the unnecessary waste of an estimated 10 million trees.

While some publishers are taking steps to reduce their environmental impact, such as printing only the amount of books that will be used and partnering with local printers to reduce carbon emissions from shipping, the transition to sustainable practices in the publishing industry is challenging. The cost of sustainable printing methods and the limited availability of recyclable materials, such as recycled paper, present significant obstacles.

Additionally, the rise of social media influencers who showcase large "book hauls" on platforms like TikTok, Instagram, and YouTube, has contributed to the issue of book waste. These hauls, which can include purchases of over 40 books, may lead to an excess of unread books that eventually end up in landfills.

Overall, the waste produced by the publishing industry is a complex issue that requires efforts from both publishers and consumers to adopt more sustainable practices and reduce the environmental impact of book production and consumption.

The use of toxic substances in the printing process

The printing industry uses a variety of toxic substances and chemicals in its processes, which can have detrimental effects on both the environment and human health. These toxic substances are used to bleach paper, colour it with ink, and bind pages together.

One of the main toxic substances used in the printing process is ink. Inks can contain harmful chemicals such as perchloroethylene, ammonium hydroxide, and ketones, which can cause a range of health issues, including dizziness, drowsiness, and central nervous system problems when inhaled. In addition, ink misting during high-speed printing can lead to the inhalation of ink fumes, causing irritation of the respiratory tracts, occupational asthma, severe headaches, and nausea.

Another toxic substance used in printing is adhesives, which are used in processes like adhesive laminating. Isocyanate prepolymers, found in adhesives, can irritate the airways and lungs, leading to occupational asthma. Lacquers, used in processes like UV curing, contain reactive acrylates or methacrylates that can cause skin, eye, and mucous membrane corrosion.

Cleaning solvents are also commonly used in printing and can have negative health impacts. Alcohol, esters, and ketones, for example, can cause dermatitis, dizziness, and central nervous system issues. Nitric, sulphuric, and hydrofluoric acids, used in etching, engraving, and platemaking, can cause skin burns, eye damage, and blisters.

The use of these toxic substances in the printing industry has led to the implementation of regulations like the Control of Substances Hazardous to Health Regulations (COSHH) to protect workers' health and minimise exposure to harmful substances. Companies are required to identify hazardous materials, assess potential routes of exposure, implement preventive measures, and provide relevant training to staff to ensure compliance with COSHH regulations.
