Recently, four 11th grade students of Tallinna 32. Keskkool have been seen working in the bioengineering laboratory. The aspiring girls Grete-Liis Tammaru, Maia Tžikanov, Luisa Aleksejev ja Mari-Ann Rõuk decided to start a student company as part of their 11th grade research project and solve a problem that occurs in everyday life. Their student company PopZip is developing 3D printed reusable lids for resealing aluminum beverage cans. The girls described that the idea was born out of a personal need, because it is not always possible to drink the entire drink at once. However, the lid created by the girls makes it possible to close the can again and put it in a bag if necessary.
The girls reached the Bioengineering research group when they turned to Tallinn University of Technology to get advice on using suitable materials. From there, they were put in contact with Kerit-Lii Joasoon, a master’s student working under senior researcher Rahul Kumar in the Bioengineering research group and Tommaso Tagliani, who have been helping PopZip with the prototype. In cooperation, a prototype has been developed and different materials have been tested. Silicone was chosen as the material for the product, since is suitable for contact with food as it is inert and has good properties for 3D printing as well as elasticity, water resistance and durability.
Inna Lipova was one among the finalists in Science in Three minutes competition
On 18th October The Science in three minutes competition found it´s end during an official gala. The competition initiated by Estonian Academy of Sciences was held in English for the first time. Bioengineering doctoral student Inna Lipova was one among the nominees and gave a powerful presentation about how food waste is being valorized into high value-added carotenoid astaxanthin through bioprocess.
