Startup Idea : Food Wastage reduction through donation

Across the world, there are restaurants that waste tons of excess food everyday. I would like to create a website/iphone/android app to establish a link between restaurants and the charity homes/needy households to enable excess food donation. We can also create a 'goodwill' points system for restaurants to get rewarded for such a noble deed which they can use for their own marketing efforts by being a responsible social business as well.
