Cleanup Day

Don’t bullsh*t, just brush!

Or, as we say here in the Netherlands: ‘niet lullen, maar poetsen’. And poetsen is what we will do. On saturday the 18th of September we’ll be rolling up the sleeves of our brewing jackets to tidy up the owls natural habitat: de Waarderpolder in Haarlem.

Everyone is invited

Come as you are and stay as long as you like. We will provide gloves, waste grabs and trash bags at the entrance to our brewery and reward every participant with a goodie bag when they’re done.

Trashbag Owl

Swap your trash for an Uiltje goodie bag!

We’re offering a swap: full trash bags for an Uiltje goodie bag. What’s in the goodie bag? Ah, that’s a surprise…

Recycle forever

We see World Cleanup Day as the perfect opportunity to clean the area up and upcycle all that trash into something interesting. To make sure that happens, all usable trash collected will go to the Beach Cleanup Foundation Stichting Juttersgeluk and will be upcycled into cool new products.
