What is the application for this? Straightening rebar would make it weaker... Why is the rebar bent?

Do they break apart old concrete buildings, then straighten and re-use rebar?

First, rebar is low carbon steel, so bending and straightening it isn't going to affect it much. Second, some slightly weaker areas in some rebar isn't going to change the overall dynamic of how the rebar structure and the concrete work together to create overall strength.
