Landfills
You have just finished your meal at a fast food restaurant and you throw your uneaten food,food wrappers,drink cups,utensils and napkins into the trash can.You don t think about that waste again.On trash pickup day in your neighborhood,you push your can out to the curb,and workers dump the contents into a big truck and haul it away.You don t have to think about that waste again,either.But maybe you have wondered,as you watch the trash truck pull away,just where that garbage ends up.
Americans generate trash at an Astonishing rate of four pounds per day per person;which translates to 600,000 tons per day or 210 million tons per year!This is almost twice as much trash per person as most other major countries.What happens to this trash?Some gets recycled or recovered and some is burned,but the majority is buried in landfills.
How Much Trash Is Generated?
Of the 210 million tons of trash,or solid waste,generated in the United States annually,about 56 million tons,or 27 percent,is either recycled or composted .The remaining trash,which is mostly unrecyclable,is discarded.
