Can any suggest a good idea for a computer science project in my college?

I  am a computer science student. Regarding the project  any good idea that can help the poor with my project and my ideas are

1. On any  occasion, the food will be wasted by us  because of food left in large amounts 

So. any app or website if u send ur location then server boy come to u and take that food to any nearby ashrams within 2hours. It is like a service based app

2.Waste management. 

anyone can  reply to any new ideas to make a good project
