Electronics comprise one of the fastest-growing sectors of the solid waste stream in the U.S., and projections anticipate the stream will continue to grow in the coming decades. Electronics are increasingly complex and contain many valuable materials, including critical minerals and materials, that are lost from the economy if not recovered.

NIST is investigating the fate of critical minerals in electronics recycling processes to improve their recovery. The activity involves characterizing the elemental compositions of bulk-separated material streams from e-scrap recycling using various analytical methods, including inductively coupled plasma optical emissions spectroscopy (ICP-OES), X-ray fluorescence (XRF), prompt gamma activation analysis, and neutron activation analysis. Understanding how critical minerals are distributed during the initial shredding and sortation process could help identify opportunities for system improvements, such that recyclers can better assess the value of their e-scrap streams and recover more critical minerals.

Recovering value from electronic products before they become waste is a growing challenge. NIST research addresses that challenge with investigations into 1) integrated circuit (IC) reuse, and 2) design for circularity. In collaboration with partners, NIST is identifying opportunities and challenges surrounding IC recovery and reuse and developing criteria and a method for determining when IC reuse can be economically viable and environmentally benign. NIST is also partnering to identify attributes that enhance the circularity of consumer electronic products, with a goal of developing a method for applying these attributes in new designs to improve the recoverability of materials and components from future products.
