Updated: Jul 29, 2019


Tallinn urban challenge is city-driven approach to innovation. Estonia’s capital defined its problem: insufficient biowaste recycling due to poor separate collection on spot. The challenge was for startups, companies and scientists with a wise idea on how to improve biowaste separate collection. Helping hands with a plan for pilot project were welcomed from all across the world. Many of the presented ideas will be available soon in Tallinn.​

Today biowaste makes up at least 1/3 of municipal solid waste. Around 30% of biowaste is recycled in Tallinn. Biowaste could be valuable raw material, but this is underused according to present system. Unfortunately, there has been no simple way to inspire biowaste separate collection at homes and in food processing facilities (canteens, restaurants etc). Biowaste treatment is usually unpleasant, smelly and “yucky”.

The main reasons citizens bring out as obstacles in waste separate collection are lack of space for different bins in the kitchen and the long distances from the nearest biowaste container. Luckily, there are great solutions ready to be taken into your everyday habits - that was also the goal of Tallinn urban challenge project to create implementation plan for improving biowaste separate collection on spot.
