This pizza box is designed by environmentally conscious organization, inc. which produces innovative green packaging solutions.
They claim that the pizza box design has remained unchanged for the past thirty years. They add that for the customers, the box is too unwieldy to store uneaten pizza and takes up too much space in the trash can and is totally environmentally unfriendly. The Green Box is manufactured from 100% recycled material and is environmentally friendly.
Here is the video introducing the Green Box.
