The reuse of products, materials, and parts can have significant environmental and economic benefits. Waste is not just created when consumers throw items away. Waste is generated throughout the life cycle of a product, from extraction of raw materials, to transportation to processing and manufacturing facilities, to manufacture and use. Reusing items or making them with less material decrease waste dramatically. Ultimately, less material will need to be recycled or sent to landfills or waste-combustion facilities.

Used goods are widely available to industries, businesses, institutions, and individuals. There are secondhand markets for entire industrial production facilities, such as breweries and chemical production plants, as well as for industrial, construction, and medical equipment. Used goods for individuals include cars, clothes, books, furniture, household items, sports equipment, and musical instruments. Sources of used goods include on-line auctions and markets, secondhand merchandise stores, classified advertisements, estate sales, auctions, rummage sales, yard sales, salvage yards, materials exchanges, trash salvaging or "dumpster diving."

Amount of Reuse

In the United States, several secondhand markets are $100 billion dollar industries, and several more fall in the $1 to $10 billion range. Each year 40 million used cars are sold in the United States, nearly three times the number of new cars purchased. Overall, secondhand markets are almost as large as consumer recycling in terms of the amount of material processed (approximately fifty million tons of paper and ten million tons of glass are recycled annually in the United States), and the economic value of secondhand markets is far greater than those for recycling.

A considerable percentage of secondhand goods are exported from the United States, especially clothing; automobiles; and industrial, construction, and medical equipment. In a number of countries, including the Czech Republic, Nigeria, Uganda, and Zimbabwe, imports of used clothing compete strongly with the domestic production of new clothes.

Theory of Reuse

Reuse can reduce the pollution and resource use associated with manufacturing a new item, and can delay or eliminate disposal of the item. In order to experience the greatest environmental benefits, reuse of an item needs to replace, at least partially, the purchase and production of a new item. In some situations, reuse may not incur any real benefits. For example, if a car owner sells or gives a car to someone who would not otherwise possess a car, and then buys a new car to replace the old one, the result is that there are now two operating cars rather than one. In other situations, the reuse of an item may
have zero effect on the production or purchase of new items. For example, if someone buys a "white elephant" at a rummage sale (perhaps a necklace or a used compact disc), that purchase will not in any way prevent or replace the purchase of a new item. However, even if reuse has no tangible environmental benefits, it can have economic and social welfare benefits. If the car example above is reconsidered, for instance, two people, not just one, now own a useful vehicle. In the compact disc example, the buyer acquires another disc for his or her pleasure, and the seller earns some perhaps much needed cash.

Reuse can replace the production and purchase of new items, especially when the first owner does not sell in order to be able to buy a new item. Examples of this sort include clothes and furniture, which are typically given away or sold at low prices by the first owners, and which second-hand buyers often buy instead of new items.

Role of Government and Industry

The U.S. government is one of the largest purveyors of used goods in the United States; it regularly sells surplus items through sealed bids, auctions, silent auctions, and fixed-price sales. On the other hand, government regulations largely prevent the purchase of used items by the U.S. government and require the labeling of products containing used parts in a way that may discourage the use of used parts by industry.

There are both incentives and disincentives for reuse by industry. Reuse, remanufacturing, repair, and refurbishment of products and parts can be economically beneficial for industry. For example, used copiers are often remanufactured and refurbished. A number of companies now sell modular, reusable carpet. On the other hand, firms in some cases have an incentive to discourage reuse of their products, in order to maintain and increase production of new goods.

Reuse by the Individual

Individuals can maximize the environmental and economic benefits of their own reuse efforts by carefully contemplating their reuse strategies, by developing the ability to make repairs, and by learning about local sources of used goods and replacement parts. The environmental and economic benefits of reuse typically increase as the size and cost of the item increase. For example, new furniture is both resource-intensive and expensive. Repair, repainting, and reupholstering of used furniture can replace the purchase of new furniture. The regular repair of shoes can considerably extend their life. Used clothing, ranging from designer clothes at consignment stores to basic items at rummage sales, is widely available. Used books, sports equipment, and musical instruments are also available at local stores and on-line. Used building materials (doors, windows, hardware, etc.) are increasingly available at salvage yards such as Urban Ore in Berkeley, California.

Reuse can have significant environmental and economic benefits by replacing the purchase of a new item. Secondhand items range from large industrial facilities and equipment to cars, sports equipment, clothes, and toys for individuals. Businesses can benefit from secondhand markets both by buying secondhand equipment and by selling surplus equipment for reuse. Individuals can make a valuable contribution to the environment and their own finances by learning to make repairs, by wisely shopping for secondhand goods, and by selling or donating their unwanted goods so that others may use them.

In March 2002, stores across Ireland began to charge an extra fifteen euro-cents for each plastic shopping bag, formerly given away to hold purchased merchandise. Before the "green" tax was implemented, Ireland's 3.9 million people used about 1.2 billion plastic bags each year. After just five months, this number was cut by ninety percent and 3.5 million euros had been raised by the tax program to be spent on environmental projects. Shoppers now bring sturdy reusable shopping bags along and enjoy the beautiful Irish countryside without the eyesore of plastic bags caught on hedgerows and blown into gutters.

Reuse, using a product more than once in its original form, is one of the preferred methods of solid waste management because it prevents materials from becoming part of the waste stream . It is a form of source reduction of waste.

Some products are specifically designed to be reusable while others are commonly reused as a matter of convenience. In the former instance, products such as canvas shopping bags and cloth napkins are meant to be used again and again, unlike their paper cousins. In the latter case, glass and plastic food containers are often reused for numerous household purposes, even though they are intended to be used only as food packaging.

Reuse of products is a basic component of diaper services and home bottled water delivery. Although neither of these services were originally created with waste reduction in mind, they do impact solid waste generation. A cotton diaper can be used 70 or more times, unlike a single-use disposable diaper. The three and five gallon bottles used by most bottled water services are picked up and taken back to the water plant for refilling, eliminating the need for consumers to buy individual gallon containers in supermarkets.

Deposit systems for beer and soft drink containers represent another form of product reuse. In these systems, consumers pay a nominal fee when they purchase beverages sold in specific types of containers. The fee is refunded when they return the empty containers to the retailer or other designated location. Virtually all beer and soft drinks used to be sold in returnable bottles. During the 1950s, the use of nonreturnable bottles and metal cans started to be more commonplace. By the mid-1980s, most beverages were packaged in nonreturnable bottles, cans, or plastic containers.

Nine states currently have legislation requiring deposits on beverage containers. The deposits are meant to be incentives to consumers to return the bottles. Where such legislation exists, between 70 and 90% of the targeted containers are returned. Litter control rather than solid waste reduction is sometimes the purpose of beverage container deposit legislation . Reduction in litter has been documented to be as high as 80%, but the impact on solid waste disposal is more difficult to calculate since beverage containers account for a relatively small portion of the waste stream.

Another type of product reuse is resale of used clothing and household items through thrift stores and garage sales. Although calculating the impact of such practices on waste generation would be extremely difficult, there is no doubt that they result in some reduction in waste disposal.
