"Bottles Saved Today"

A Flow-Metered Refill Tap, Its Chalkboard Tally, and the Allocation Rule Adopted on Its Reading

A paper from the School of Emergent Priorities describes a flow-metered drinking tap, built by a precinct's refill-station steward, that converts dispensed volume into 600 mL bottle-equivalents and posts the running total on a chalkboard-style display. Across six foyer taps and one twelve-week term, the pooled median weekday tally rose from 181 to 469 once Facilities apportioned the term's plastics-reduction allocation by each nearest tap's reading, whether or not the tap carried a display, and Facilities has adopted the apportionment as a standing rule with no deduction and no in-term recalibration.
