@burcidi-- I know what you mean. I also experienced that when I visited a sugar manufacturing plant. It's due to the juice being clarified and then turned into froth before it evaporates into crystals.
I learned a lot from that visit to the plant. For example, I learned that the process doesn't end with sugar crystals. Some of the sugar crystals are then processed into syrups and sugar alcohol which are added to many processed foods in place of sugar.
The pulp that's left behind after the sugar cane has been pressed is transported to other manufacturing sites where they are made into paper. And I think that the pulp from sugar beets are fed to animals.
So while sugar is being made, nothing gets wasted. The entire sugar cane or sugar beet is being used.
