A great post from my Emma Wharton on the Life at HOK blog. Here's what she says:
Herman Miller’s iconic Aeron chair today has received the McDonough Braungart Design Chemistry (MBDC) Cradle to Cradle Silver certification for environmentally friendly design. The design is already 94 percent recyclable and made up of up to 64 percent recycled materials. The seat frame and back contain over 60 percent recycled content, made from approximately 36 recycled two-liter plastic beverage bottles per chair. Aeron is also assembled with 100 percent renewable energy and is GREENGUARD certified.
