I read in an article that on an average indians changes mobiles for every 24months. May be because they wants to update or the existing device damged. Not only mobiles, Laptops, Pcs damaged devices turns into e-waste. Every gadget has rare earth metals and that can be recycleabe. Instead of opening another resturant or cafe, if someone works on it in an organised way, collecting and recycling turns into impactful startup.
