One of my favourite examples of the use of waste material is by the dutch designer Piet Hein Eek. His use of basic manufacture waste material - wood, steel, etc. - is not for the climate change fight, i.e. to try to lower the amount of material going to landfill, but his goal is to be as different from what 'design' has become today.

"The scrapwood cupboard from 1990 was my reaction against the prevalent craving for flawlessness. I wanted to show that products that aren't perfect still can appeal to our sense of aestetic and functionality" (Piet Hein Eek)
