USLCI Quarterly Release: Fall 2025 Update

The USLCI Fall Quarter 2025 release is ready. The new release is available through NREL’s USLCI repository on the Federal LCA Commons (FLCAC). The update in openLCA zolca and JSON-LD formats can also be downloaded from the USLCI GitHub Support Content Downloads page.

Overview of USLCI 2025 Fall Quarter Changes:

  • Added industrial wastewater treatment processes
    • 16 unit processes - 7 with broad applicability and 9 specific to the cement, concrete and flat glass industries. Processes include sludge drying beds, settling lagoon, pH neutralization, granular media filtration, filter press, chlorination, dichlorination, chemically enhance clarification, and effluent release.
  • Added end of life processes
    • Landfilling and combustion of mixed municipal solid waste (MSW) and landfilling of construction materials (steel, glass, asphalt, concrete). Processes were adapted from the Waste Reduction Model (WARM) by connecting Technosphere flows to USLCI and mapping elementary flows to the Federal Elementary Flow List (FEDEFL).
    • More information about the data formatting process can be found here.

  • Filled in data gaps by mapping flows and adding bridges to USEEIO

     

More details are available in the USLCI Press Release brief. The Change Log is here and USLCI Content Support is available at the USLCI Content Wiki page, which includes access to archived versions of the USLCI.
