Oregon on Friday became the 12th state to ban the disposal of certain electronics into landfills.
The second phase of the state's electronics recycling law makes it illegal to trash televisions, computers and monitors and could lead to a $500 fine.
Oregon's e-cycle law was passed in 2007 to slow electronics waste and the toxins released as they break down.
The first phase was launched a year ago and required electronics manufacturers to pay for a permanent statewide program with free, convenient recycling.
In the first eight months, Oregon collected more than 14.3 million pounds of TVs, computers and monitors.
