Elliot's idea for sustainability was to install consistently color-coded recycling bins in front of every type of dwelling all over the country. White bins were for paper, yellow for plastic, red for cans, green for bottles, violet for clothing and shoes, and blue for all toxic waste. The idea was to send color matching trucks to collect the content of the beans of the same color as the trucks were. This way the yellow truck would collect the yellow bins, the red one, red ones, etc. Trucks picking up the regular trash were to be painted grey. At this point the waste companies protested the change of the color of their businesses.
