Horizon Sustainability Scanner
The Horizon Sustainability Scanner, as you can probably guess, is a barcode scanner that will teach you how to dispose of your waste. You can also use it at the store, so you know which products you should buy and which ones you should avoid.
The app also teaches you more about the products and how wasteful their ingredients are. For instance, when you buy food, you can see the ingredients used and how positively or negatively they impact the environment.
Another cool feature is that it also shows you how to store your food properly so it lasts longer.
