ENVIRONMENTAL HEALTH: Green Apples - Macs Impacts On The Environment‏

In planning the design of the MacBook line of personal computers, Apple set out to make it the greenest, most environmentally friendly computer in the world. Their goal was to ensure that every new MacBook would be built using recyclable materials while at the same time avoiding many of the harmful chemicals and other substances that are present in other computers.

Some of the formidable goals Apple computer set out for itself was eliminating the toxic mercury used in CCFL backlights and the arsenic that is present in the glass of traditional LCD displays.

To do this, the engineers at Apple replaced these outdated and dangerous toxins by choosing mercury-free LED technology and arsenic-free glass. Other toxins in personal computers included polyvinyl chloride (PVC) that is commonly used in circuit boards, connectors, insulators, internal cables and even more components. Another toxin the computer company wanted to eliminate was brominated flame retardants.

And the company has been completely successful. The MacBook laptop computers are produced without any of these toxins and the same is true for the Apple iPod family - the iPod touch, iPod classic and iPod Nano. The iPhone 3G and the Apple Mac LED Cinema Display are also free of those toxic elements.

The components in this computer are also highly recyclable. The enclosure - or body - is formed from a single piece of solid, recyclable aluminum. This single sheet technology replaces dozens of extraneous parts. The laptop computers' displays are made of recyclable glass and can be recycled yet again. The raw materials used in the new MacBook computers can be reused again and again in other products.

But the company didn't stop there in their environmental commitment. To reduce the energy consumed by the laptop, the new hard-drive spins down automatically when inactive. The new LED-backlit display uses 30 percent less power than conventional LCD displays and the laptop's display is designed to automatically dim when the user is working in a darker environment. When it comes to final energy consumption, the MacBook can run on one-quarter of the power of a single light bulb.

In addition, the battery in the 17-inch MacBook Pro can last up to five years - that equals roughly 1000 recharges with normal use. This means the laptop computer uses one battery during the time other companies' notebooks use three. Longer battery life equals fewer spent computer batteries in our landfills, and that's good news for the environment. specializes in finding used apple laptops, Apple laptop articles, and used macbook pro.
