What constitutes waste for you? Is it when you decide something is useless for you? Or when you throw out something? Where you dispose of them matters because it defines where it goes and it determines what happen to the materials or matter and if it is classified as waste. The overall psyche of our current populace is mostly driven by the out of sight, out of mind approach to waste.
We could change the very idea of waste so that there is better recognition of the value of the material. This helps reduce the waste and encourage reusing.
Or we can make it way easier to recycle. But recycling will have to be different from disposal. And the recycling activity needs to be valued differently.
