Beer from food waste, goose droppings in Lahti, Finland

Lahti in Finland is the European Green Capital 2021 and a local brew house Ant Brew celebrates the same by creating a beer using food waste, wild herbs and goose droppings to share a message of waste less circular economy. 
Ant Brew uses left over bread, fruits, berries etc. They also use goose droppings collected from parks to smoke their malt. "This series of beers is our way to create important discussions about food waste, utilization of waste, urban farming, and local and wild food among beer enthusiasts. Working with the Lahti Green Capital has been great. We are constantly developing ways to utilize new ingredients in brewing, and are not afraid to think outside of the box" says Ant Brew’s Kari Puttonen.

The beers showcase how all waste can be utilized. City of Lahti aims to be completely wasteless circular economy city by 2050, and at the moment 99% of the city’s household waste is already repurposed. 
First to be released is a wit-style beer brewed with orange peels from a local market’s juice pressing station, and fruit purees that have exceeded their best before-date.
