Analysis of end markets for collected Minnesota household e-waste

PDF icon Analysis of end markets for collected Minnesota household e-waste

Minnesota's efforts to collect waste consumer electronics continue to impress, with annual statewide averages of over 6 pounds of "covered electronic devices" per person and 16 pounds per household. Old televisions and computer monitors make up the majority of the pounds; old CRT-based units are typically just unwanted as people upgrade to newer models that are smaller, lighter, and more energy efficient.

Knowing what comes out of consumer electronics is important in setting a fair and competitive market price for collection and recycling services.

Research was conducted for the Minnesota Pollution Control Agency under contract as a collaboration of Greeneye Partners and Reclay StewardEdge Inc. Recyclers that participated in the project, completing the survey of end markets and processing, represented over 90% of the total weight of covered electronic devices recycled at that time.
