When one considers the size of Anchorage ,and the small amount of problems with bears , the situation doesn't warrant the expense and trouble of people using bear resistant cans . Only 20 percent of customers who are under SWS's government forced rules can be forced to use these cans . They are also forced to have refuse service whether they want it or not.  The other  80 percent don't even have to have refuse service if they don't want it , so trying to get them to use these special cans in next to impossible.  The best solution is for people to keep their refuse stored in locked sheds or garages until the morning of collection day .  Unless everyone in Anchorage used these special cans---it's a waste of time and money getting a handful to go along . It's like forcing people to recycle---it's never going to happen in Anchorage .
