OeTTINGER Returnable Month of May: Dispose of crown caps in the proper manner.

Crown caps are mainly made out of tinplate. Of course, this can be recycled and reused, but only if it is disposed of correctly. Given that tinplate is recycled differently depending on where you live, it is best to ask your local waste management authority if crown caps in your area go in the yellow bin, the yellow sack, or the recycling container.
