Does anyone have suggestions for effective shapes and colors for compost and trash openings to discourage contamination in a student dining hall?
There is ample room for signs and displays depicting proper sorting, but we are wondering if certain shapes and colors have been shown to be more effective for helping people choose the right bin with minimal effort.
Any suggestions would be most helpful, thanks.

Hi Honore,
At the University of Winnipeg we have a four box system - garbage is black or grey, recycling is blue, and composting in brown. All of the bins are rectangular is shape, and the compost bin has a turning lid flap.
I don't know if the colours or shapes of the bins have affected the success of our system. We have found that advertising the program, educating students, staff, and campus visitors, having signage directly above the compost station areas, and having the garbage, recycling, and composting bins side by side to have made the largest difference in terms of decreasing the amount of contaminated compost bins.
Good luck with your compost program!
