Recycling assists with trash management. Since most of our planes have limited space in trash receptacles, the cans will take up less space if they are returned to an insert.
We all have a global responsibility to be Green and help our environment. Consider that an aluminum can placed in the trash will find its way to a landfill and will not decompose for over 500 years. A can that is recycled will be back on the shelf as a new commodity in as little as 60 days! 500 years or 60 days? Which should you choose?
