ColorThrow / Concept of Recycling

Garbage sorting has always been a major problem, due to people won’t always throw their waste and garbage in the right way.Even they do want to, sometimes it’s still confusing.
Our government spent millions of dollars on re-sorting these garbage every year, what if improving the way we throw garbage by only using simple elements like colors?

Printing lines with colors under every product’s bar code.Each color represents a catagory of garbage, so products with multiple materials might have it’s line composed in multiple colors.
Making this easier and more intuitive to organize are waste and garbage.
