Best Ideas at Kaleidoskoop aim to Improve the Environment

Green mindset is the common feature of the teams S-Kub and Sorter, winners of the 14th Kaleidoskoop business ideas competition. Both have a bigger goal of saving the planet and promoting environmentally friendly behavior.

Sorter, an international team of the University of Tartu, won not only the possibility to participate in the all-Estonian STARTER finals but also received the monetary award from Tartu City Government. Team Sorter is developing an application that uses the barcode to help people sort waste correctly. The idea stemmed from waste sorters’ common concern that they are often not sure what waste goes to which bin. The team has already got much feedback from potential users who say that this app should have been on the market long time ago. Among others, also waste management companies have shown interest in this app since it brings them a cleaner waste stream. The team has succeeded in involving companies in the development process who are willing to provide financial support to accelerate the launch of this product.

The main prize at Kaleidoskoop and tickets to Latitude59 were given to the team of Estonian Business School students S-Kub, who produce solid shampoo cubes. According to S-Kub members, their product helps to save billions of liters of water and reduce the production of plastic bottles. Today their first products are ready and they are actively preparing for sales. Team leader Cathy Vivien Vahi said, “We applied for Kaleidoskoop to test the idea and get feedback, and the win was therefore a great surprise for us. Online pitching was also a new experience. Our team is sharing the common concern that is also our slogan – save the planet from plastic”.
