One method of the active transport is the bulk transport - using the endocytosis or exocytosis for the process of moving bigparticles through the membrane.
Another example would be with the use of special transport proteins in plasma membrane. These proteins to change their shapes thanks to ATP (Adenosine triphosphate).This is how they manage transport materials from low to high concentration.

Active transport methods:
- symport - across one protein, two molecules are transported in the same time and direction
- antiport - across one protein, two molecules are transported in opposite directions, which one enters into protein and one leaves it.

I hope I helped :D
