活用する implies systematic or effective utilization, especially of skills or resources, while 役立てる is broader and used in everyday contexts.
利り用ようN4
利用する means to use or take advantage of something and can be neutral or self-serving, whereas 役立てる always implies putting something to a beneficial use.
生いかすN2
生かす means to make the most of something like experience or skill for good effect, similar to 役立てる but with a more personal, growth-oriented nuance.

無む駄だにする
無駄にする means to waste something, the opposite of 役立てる, which means to make good use of it.

Compound of 役 (role, use) and 立てる (to set up, to make stand). The combination yields the meaning 'to make something serve a role'.
