If you want to be perfectly goody two shoes your local dump/transfer station should have an asbestos drop off, it costs a little more but for something that small you're talking pennies
be more concerned that it got missed by the previous removal, probably worth poking around to check if they missed more
like other anon said the material is safe it's the dust that causes problems, wear a mask and avoid breaking or sanding it and you'll be fine
