Short answer: You can't.

Long answer: most non-Nanopod units from the Barracks can be converted into Infected units if you have an Infection Test Facility. That could only be built around Halloween last year, though there is a good chance it will return at some point, likely around Halloween again. However, most units you would want to get rid of turn into Infected that are at least as useless.
