Goose droppings in beer brewing – this Finnish Green Capital takes circular economy to the next level

This summer Finns can drink beer brewed with wild herbs, food waste and even goose feces. The new beers by a local microbrewery Ant Brew celebrate the European Green Capital year of the city of Lahti and share an important message of a wasteless circular economy.

The Finnish city of Lahti is known for their pioneering environmental action, and for their open-minded co-operation with local people. Now the European Green Capital 2021 joins forces with the local microbrewery Ant Brew by crafting a new beer series. The Wasted Potential beers are brewed with wild herbs, local food waste, like bread, berries and fruits – and even goose droppings.

The poop is used in a food-safe way to smoke malt to create a unique stout beer. The goose droppings are gathered from local parks, where geese are causing a messy problem. Now, the local parks get cleaner and the special edition summer beverages are perfect for a picnic in the park – a true two birds with one stone type of solution.

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.

A taste of potential that was not wasted

– A sustainable future demands effective use of resources and innovative ways of recycling. Lahti has several well-known breweries, so what would be a better way to celebrate our environment this summer than locally brewed beers, says Saara Piispanen, Head of Communications of Lahti European Green Capital.

The beer that uses goose droppings in the malt smoking process will be released later in the summer. First to be released is a wit-style beer inspired by waste-free circular economy: brewed with orange peels from a local market’s juice pressing station, and fruit purees that have exceeded their best before-date.

– 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.

– Our environment and circular economy are important for us, and we want to discuss these topics in interesting ways. Together we can create solutions that are eco-friendly and represent sustainable consumption, says Piispanen.
