Recycling Quotes (5 quotes)

Aluminum has been called the sustainability nutrient of the world, and for good reason. Consider that 75% of all the aluminum made since 1886 is still in use. So from a sustainability standpoint alone, yes, [Charles] Hall really did become that benefactor to humanity—big time.
As quoted in 'Alcoa Co-Founder Charles Hall Smelt Success' (20 Jul 2012), article on investors.com website.

Most manufacturers take resources out of the ground and convert them to products that are designed to be thrown away or incinerated within months. We call these “cradle to grave” product flows. Our answer to that is “cradle to cradle” design. Everything is reused—either returned to the soil as nontoxic “biological nutrients” that will biodegrade safely, or returned to industry as “technical nutrients” that can be infinitely recycled.
In interview article, 'Designing For The Future', Newsweek (15 May 2005).

Mostly, I spend my time being a mother to my two children, working in my organic garden, raising masses of sweet peas, being passionately involved in conservation, recycling and solar energy.

The Pacific coral reef, as a kind of oasis in a desert, can stand as an object lesson for man who must now learn that mutualism between autotrophic and heterotrophic components, and between producers and consumers in the societal realm, coupled with efficient recycling of materials and use of energy, are the keys to maintaining prosperity in a world of limited resources.

What we call recycling is typically the product losing its quality. Paper gets mixed with other papers, re-chlorinated and contaminated with toxic inks. The fiber length gets shorter…and you end up with gray, fuzzy stuff that doesn't really work for you. That's downcycling. Michael Braungart and I coined the term upcycling, meaning that the product could actually get better as it comes through the system.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
