ERCC compiles the average weights from several state electronics recycling law programs where the number of units, unit weight, and product device type is recorded. Currently, these data are only tracked under the Maine, Oregon (sampling) and Washington (sampling until 2014) programs. Below is the change over time in average weights for 2010-2014. (All numbers are in pounds.)
*Maine average monitor weight for 2015 includes laptops and all-in-ones and is not included on these charts: 21.88 pounds (2016 data not yet available).
