Most people assume that it is impossible to recycle milk cartons just because several curb-side recycling programs do not accept them. This is a big concern for people who wish to recycle and live a green lifestyle. A Green Luvin' blog post discussed that a National Geographic documentary entitled Human Footprint indicated that "America consumes 989,985,594,240 half gallons of milk over the course of a lifetime and it takes more than one trillion kilowatt-hours of energy to produce, ship and landfill the milk cartons. That amount of energy emits 740,674,244 tons of greenhouse gases." It is very understandable why many people want to know how to recycle milk cartons.
