Food waste, its impact, and what this means for sustainable business.

Saw this article on Treehugger the other day, its about the impact of food waste.

I've worked for a number of food service places and I was always surprised how much food gets thrown out due to spoilage or "bad" quality. This seems like a "low-hanging fruit" where a business, especially a small business, could save money and have a positive impact easily. Proper food waste management isn't extremely difficult but many restaurants do a poor job at it.

This is an important and easy way for a green branding agency to reduce a businesses environmental impact and show how sustainable practices can save a business money. I wonder if anyone out in the advertising world has addressed this problem?
