Insted of disposing of their scarp tubes, STS Pack Holding decided to take the initiative of finding a new purpose for such waste. In general, the company recycles the "unsavable" tubes, but in some cases the packages have small defects which do not affect their usability. Therefore, STS together with RIC "Ambitious Gabrovo" came up with the idea of creating the Happy Tube. Every saved tube is a happy tube, especially when it has a purpose!
