- "The final resting place for all contraband within Hill Valley, the decycling bin ensures that socially toxic items will never find their way back into the hands of the general public in any way, shape or form."
- —Danny Parker Jr.
The decycling bin was a type of disposal system invented by Citizen Brown in an alternate timeline. It was located in the Hill Valley Courthouse Square near the base of the clock tower. Very few people knew where the decycling bin led to, as, underneath the stone bin, it was a large tube that traveled underground. It was assumed that things thrown inside were incinerated, but in fact they were stored in an underground chamber. The reason for this is unknown.
