LA County just sent out its guidelines for dealing with O Trashenbaum. On Mackinac Island they use old Christmas trees to mark the ice bridge between the Island and Saint Ignace, the closest town on the mainland. Since they don't need buoys between the Port and Catalina, best refer to the news release below.
Holiday Greening is Easy - Recycle your Christmas Tree
Between Thanksgiving to New Year’s Day, Americans throw away 25 percent more trash than during any other time of year. This year, help reduce the trash load and take the work out of getting rid of your Christmas tree - recycle it!
Starting December 26, 2009 through January 16, 2010, residents can recycle their Christmas trees by placing them at curbside on their regular collection day or taking them to a collection site.
To enjoy the benefits of this special holiday recycling service, residents must remove all ornaments including tinsel, decorations, and metal and plastic tree stands from their trees before placing them at curbside or turning them in at a collection site. Trees over six feet tall should be cut in half for easier collection.
Residents who miss the curbside recycling dates can cut their trees into smaller pieces and place them in their green waste container. The trees collected by residential waste haulers will be recycled into compost, mulch, or ground cover. This helps preserve our natural resources and reduce waste too.
