Power hour/Glass and Pfand
The big room in K20 basement is overflowing with stuff. Take it out and sell or trash it.
Prepare a bike trailer or a hand cart.
Crates of glass bottles are exactly half the size of the foldable box, so they fit nicely on the trailers.
Place boxes on the vehicle, add loose bags filled with plastic bottles as needed, and secure it all with straps (cupboard near the entrance).
Be careful not to lose the load when going down the stairs - perhaps you want to load bags outside.
Destinations
REWE buys most kinds of bottles. Other shops like LIDL are closer but might refuse half of your load.
If you go inside a shop, lock your vehicle.
Some shops don't like it if you take the cart inside.
Items
First, sell all the sellable stuff by shoving it inside the machine in the shop. Whatever is left, throw into the nearby containers with glass outside the shop, or just throw in the appropriate trash container.
Receipts
Cash the receipt at the checkout of the shop. Put the money in the money box in The Office. KH Members have the key.
