Recycling Myths

MYTH 5: WE SQUANDER IRREPLACEABLE RESOURCES WHEN WE DON'T RECYCLE.

In fact, available stocks of most natural resources are growing rather than shrinking, but the reason is not recycling (Foster and Rosenzweig 2003).
Market prices are the best measure of natural resource scarcity. Rising prices imply that a resource is getting more scarce. Falling prices imply that it is becoming more plentiful. Applying this measure to oil, we find that over the past 125 years, oil has become no more scarce, despite our growing use of it. Reserves of other fossil fuels as well as other natural resources are also growing.

Thanks to innovation, we now produce about twice as much output per unit of energy as we did 50 years ago and five times as much as we did 200 years ago. Optical fiber carries 625 times more calls than the copper wire of 20 years ago, bridges are built with less steel, and automobile and truck engines consume less fuel per unit of work performed. The list goes on and on. Human innovation continues to increase the amount of resources at our command.

MYTH 6: RECYCLING ALWAYS PROTECTS THE ENVIRONMENT.
Recycling is a manufacturing process with environmental impacts. Viewed across a wide spectrum of goods, recycling sometimes cuts pollution, but not always. The EPA has examined both virgin paper processing and recycled paper processing for toxic substances and found that toxins often are more prevalent in the recycling processes…

MYTH 7: RECYCLING SAVES RESOURCES.
It is widely claimed that recycling "saves resources." Proponents usually focus on savings of a specific resource, or they single out particularly successful examples such as the recycling of aluminum cans.

But using less of one resource generally means using more of other resources. Franklin Associates, a firm that consults on behalf of the EPA, has compared the costs per ton of handling rubbish through three methods: disposal into landfills (but with a voluntary drop-off or buy-back recycling program), a baseline curbside recycling program, and an extensive curbside recycling program.

On average, extensive recycling is 35 percent more costly than conventional disposal, and basic curbside recycling is 55 percent more costly than conventional disposal. That is, curbside recycling uses far more resources. As one expert puts it, adding curbside recycling is "like moving from once-a-week garbage collection to twice a week" (Bailey 1995, A8).
