Waste in the United States recognized the environmental issue that landfills create, and has been creating bans on U.S. landfill. Although this may create more environmental stability in the United States, it has become a major environmental and health issue in the countries to which the electronic waste is being shipped. Waste in the United States As a nation, Americans generate more waste than any other nation in the world, officially with 4.4 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, with another study estimating 7.1 pounds per capita per day.

Radian per second Radian per second The radian per second (symbol: rad·s or rad/s) is the SI unit of rotational speed (angular velocity), commonly denoted by the Greek letter "ω" (omega). The radian per second is also the unit of angular frequency. The radian per second is defined as the change in the orientation of an object, in radians, every second. Since the radian is a dimensionless unit, the radian per second is dimensionally equivalent to the hertz—both are defined as s. This may lead to confusion between the quantities angular frequency "ω" and frequency "ν". A use of the "unit radian per
