The activity of hydration and energization of the athletes during their sport activity is mainly represented in the consumption of hydrating drinks and energy gels. Most of these products have single-use sachets that are commonly disposed at roadside ditches because of the limitations of the activity. Also these packages are made of materials which by their composition are almost never recycled.
As a solution we propose to pack the gel within alginate bubbles which can be accumulated in the quantities of up to 5 bubbles inside a small portable tube. The tube can be adapted to different sports activities and allow to be filled after each session.
Gel bubbles can be purchased in specialized stores and presentations of several units (20, 50 and 100).
