Can I use a semicolon to add more information at the end of a sentence?

I have a question on whether semicolons can be used to add information at the end of a sentence, something like this:

"This year, the university decided to deliver all courses online; rendering senior lecturers worried, since they are not quite adept with distance learning technology."

I’m also not sure whether "rendering senior lecturers worried…." is an independent clause.

Any help is appreciated!
Thank you in advance.
