Disposable Batteries: Environmental and Social Impact
This paper traces the complete lifecycle of disposable batteries, beginning with their invention by Luigi Galvani and Alessandro Volta in the late eighteenth century and continuing through modern alkaline cell construction. It examines the environmental hazards posed by battery disposal, including mercury and cadmium contamination of groundwater and landfills, as well as the limitations of rechargeable alternatives. The paper also considers peripheral impacts such as packaging materials and transportation emissions, and concludes with a discussion of the social dimensions of battery use and disposal. The paper draws on sources in environmental health, archaeology of garbage, and consumer science to argue that both industry and consumers must take greater responsibility for reducing battery-related pollution.

What makes this paper effective
- The paper follows a clear cradle-to-grave structure, tracing batteries from invention through use, disposal, and recycling, which gives readers a logical and complete picture of the topic.
- It integrates specific statistical evidence—such as the statistic that batteries contribute to over 50% of mercury and cadmium in landfills despite making up less than half a percent of waste by weight—to ground its environmental claims in concrete data.
- The paper balances primary environmental concerns with secondary (peripheral and social) impacts, demonstrating breadth of analysis appropriate for an introductory college assignment.
Key academic technique demonstrated
The paper demonstrates the use of multiple source types—encyclopedias, scientific journals, and popular environmental publications—to build a converging argument. By synthesizing these sources across different sections, the author shows how a single product can be analyzed from historical, scientific, and sociological perspectives simultaneously.
Structure breakdown
The paper opens with a brief introduction stating its scope, then moves through seven sections: historical origins, common uses, environmental hazards of disposal, peripheral impacts (packaging and transport), and social implications. It closes with a call to action directed at both industry and individual consumers. Each section is relatively short and self-contained, making it a model of organized expository writing at the introductory undergraduate level.
Introduction and Purpose
Disposable batteries have transformed the way we live and the types of activities we engage in. The purpose of this paper is to provide the reader with a natural history of disposable batteries — from the time raw materials are extracted from the earth to the time they are recycled or placed in a landfill. It seeks to explain the environmental impact that batteries have along the path of creation, use, and disposal. This paper also discusses the peripheral impact of batteries, including how they are shipped, how much fuel is used, and how much pollution is created. Finally, it examines the social impact of batteries and considers the societies that make, use, and dispose of them.
Natural History of Disposable Batteries
The concept of batteries was first discovered between 1780 and 1786 by Luigi Galvani. Galvani found that connecting iron and brass created an electrical current. His ideas were expanded upon by Alessandro Volta from 1796 to 1799 with the creation of voltaic electricity. Voltaic electricity was produced when Volta experimented with stacking silver and zinc plates to form a pile, creating the first dry battery. Volta also created the first "crown of cups," which consisted of silver and zinc discs covered in a salt solution.
Since that time, the way in which disposable batteries — particularly alkaline batteries — are made has progressed remarkably. Today, disposable dry-cell flashlight batteries consist of an electric cell, while larger batteries are made up of a group of cells connected to act as a source of direct electric current at a given voltage. A cell consists of two dissimilar substances — a positive electrode and a negative electrode — that conduct electricity, and a third substance, an electrolyte, that acts chemically on the electrodes. A group of several such cells connected together is called a battery. The two electrodes are connected by an external circuit (such as a piece of copper wire), and the electrolyte functions as an ionic conductor for the transfer of electrons between the electrodes. The voltage, or electromotive force, depends on the chemical properties of the substances used but is not affected by the size of the electrodes or the amount of electrolyte (Battery, Electric, 2000).
Uses of Disposable Batteries
Disposable batteries are used to power a wide variety of appliances and consumer goods, including CD players, radios, clocks, portable televisions, toys, games, watches, and various electronic gadgets.
Batteries are also used to power vehicles. These batteries have longer lives and can be recharged, but ultimately they too must be disposed of.
Environmental Impact
The environmental impact of creating batteries is not as hazardous as the impact of disposing of them. The book Rubbish!: The Archaeology of Garbage explores the impact of pollution on the environment, discussing an experiment associated with the Garbage Project that began in 1971. The book examines the various ways in which disposable batteries can affect the world by leaking lethal substances into the ground. It also addresses the problems associated with landfills and explains that concerns about garbage disposal have existed for centuries. The authors contend that while this concern is well founded, American cities are cleaner today than they have ever been, owing in part to governmental policies and emission standards. Nevertheless, the book asserts that we must continue to seek ways to prevent the harmful materials found in batteries from seeping into the ground and harming both the environment and the public (Murphy & Rathje, 2001).
Indeed, the pollution caused by disposable batteries may prove to be a serious problem in the near future. According to an article entitled "Green Batteries: Powering Innovation":
"Americans go through 2.5 billion batteries per year, most of which wind up in local landfills. That boils down to about two pounds of batteries per household per year. And although batteries make up less than half of one percent of U.S. waste by weight, leaching and decomposing batteries contribute to more than 50% of the mercury and cadmium in landfills, according to a survey by the San Francisco Recycling Program. Such toxic heavy metals can contaminate groundwater, posing a risk to the communities served by the water source." (Carpi, 1994)
The article also asserts that the mercury used to create batteries may devastate the environment in the future. It notes a 71% decrease in the amount of mercury used to manufacture disposable batteries; however, it points out that if the casings of these batteries begin to erode, they will leak mercury into the ground.
Many experts believe that one remedy for pollution caused by disposable batteries is the adoption of rechargeable batteries. However, rechargeable batteries do not last forever and must eventually be disposed of as well. Their disposal can also be harmful because they contain toxic materials such as cobalt, which is believed to cause pneumonia and asthma. These batteries can also leak cadmium, a toxic substance capable of contaminating the water supply. According to an article in the journal Environmental Health Perspectives, "Inhaled cadmium, according to the Agency for Toxic Substances and Disease Registry (ATSDR), can cause lung damage and death, whereas long-term exposure can cause kidney disease. According to the Department of Health and Human Services, cadmium 'may reasonably be anticipated to be a carcinogen'" (Frazer, 2002).
Attempting to recycle these batteries can be extremely expensive. It is virtually impossible to purify mercury sufficiently to reuse it in new batteries. There are, however, programs that collect batteries and ensure they are sent to a hazardous waste landfill rather than a regular one.
Conclusion and Recommendations
It seems that in time these societies will discover ways to create batteries that are not harmful to the environment at all. In addition, they will discover ways to reduce the damage done by old batteries that have already been disposed of. Consumers must also begin purchasing rechargeable batteries, which would reduce the total number of batteries discarded each year. Citizens should also seek out programs that ensure their used batteries are taken to hazardous waste disposal sites, where they can be handled with greater care and less risk to the surrounding environment.
