Spotted on city trash cans throughout Berlin. The message: don’t throw your bottles in the bin. Instead, leave them outside on the ground.
Refunds for (beer) bottles supplement the livelihoods of many residents in the city. By leaving the bottles outside of the bins, people can make it easier for a second economy to thrive and, somewhat counter-intuitively, help keep the streets cleaner by supporting incomes of those less fortunate.
Interesting how public art (or public service announcements?) can endorse these norms and inform visitors of Berlin’s eccentric recycling policy.
