Most hombrewers who bottle are bottling, at least in part, in recycled beer bottles. They once held carbonated beer so they should be up to the task again. I bottle and all of my 400+ bottles are recycled. I have had only a single bottle bomb in about 8 months of brewing, a bottle of infected beer. I have overcarbed some cider so much that the bottle caps bulged outward but not a single bottle burst because of it (but I wouldn't suggest it as standard practice).
