Alaskan for 30+ yrs -- What can you do? Don't burn it or dump it in the woods, use a bear-resistant trash can.  If your garbage pickup service doesn't offer them as an option, use a 55-gallon steel drum with a locking ring on the lid.  Lock the ring.  By the way, what does "sealed can" mean to you?  A twist-tie on a plastic bag?  A lid that my 4-year-old granddaughter could get off?  The final story on the lad in Seward was that he might have seen a bear but, if so, the bear didn't get close enough to touch him.
