Do you think Interface Carpets business model is infinitely sustainable, or will there come a time when they won't be able to continue making carpets in this manner $($think about the raw materials that go into making carpets $-$ is there an endless supply of raw materials for carpeting?$)$ Discuss the long term sustainability of other kinds of recycled materials like metals $($think aluminum cans$),$ paper $($think cardboard boxes$),$ plastics $($think soda and milk containers$)$ and the impact that recycling $($or lack of recycling$)$ will have on the industries and consumers that have historically relied on these materials.

How does Interface Carpet's manufacturing model give it a competitive advantage over the competition in terms of sales and profitability? Do you think this is a model that other companies could or should follow? Why or why not?
