About this file
This is an Addendum to Request for Proposal (RFP) No. 6-S176-Q-00258-00 issued by Argonne National Laboratory's Procurement Department on May 18, 2026. The addendum extends the offer deadline from May 19, 2026 to May 29, 2026 at 3:00 PM CDT and provides clarifications to technical requirements through responses to seven offeror questions. Offerors must acknowledge receipt of this addendum by signing and returning the letter via email to the Procurement Department.
The addendum clarifies that the X-ray transmission (XRT)-based sorting system will be used as a flexible research platform across multiple separate experimental campaigns rather than processing a single mixed feedstock. Target materials include lithium-ion batteries (with emphasis on distinguishing between battery chemistries such as NMC, LFP, and NCA), minerals, and metals—with plastic sorting limited to separation of plastics from metals only. Particle size ranges and material specifications remain largely undefined as the system must accommodate varying feedstocks across different research projects. Performance priorities are ranked as detection limit, purity, and recovery, with throughput as a lower priority; offerors should provide estimated performance metrics. The base proposal should include XRT capability, with optional inclusion of color, NIR, and laser sensors if cost-effective; XRF sensor capability as a future addition is preferred but not required. Argonne requires access to all raw detector data, corrected X-ray images, dual-energy maps, Z-effective maps, and classification metadata to support external analysis and custom algorithm development.

05/18/2026 This addendum is being issued to modify the subject REQUEST FOR Proposal (RFP) 6-S176-Q-00258-00 as follows:
· Offer deadline extended to 3:00pm May 29, 2026.
· Provide responses to questions below:
1. Please define the target mineral and ore species and their particle/object size ranges.
a. This is largely unknown at this point since this will be used as a research tool on an array of feedstocks and will change depending on project. It would be good to know approximate particle size ranges that would work for the system.
2. Please define the target plastics: color sorting, polymer sorting, PVC/non-PVC, density-based sorting, or contaminant detection?
a. We will not be targeting plastics sorting for this application. So that is not needed. Using XRT to separate plastics from metals should be sufficient for this purpose.
3. Please define the target metals: ferrous/non-ferrous, Al/Cu/Ni/Co/Fe, alloys, foils, wires, housings, or mixed scrap?
a. Please see the answer to 1. The battery sorting example can serve as a guide here, where we would like to distinguish among Li-ion battery chemistries, e.g., NMC, LMO, NCA vs LFP. If the system can distinguish between those chemistries, it should be able to handle the majority of the other applications
4. Are batteries, minerals, plastics, and metals expected to be processed as one mixed feedstock or as separate experimental campaigns?
a. No, these will all be separate campaigns when using the system. This system is largely a research device, so it should be flexible enough to switch between models and adjust across campaigns.
5. What minimum performance metrics are expected for each material group: throughput, purity, recovery, detection limits?
a. I would prioritize in this order: detection limit, purity, recovery. Throughput is lower on the priority list. We do not have hard numbers for this category, but an estimate for the categories presented would be helpful. Using a battery or a mineral-sorting application to illustrate these numbers would be ideal.
6. Is XRT-only sorting acceptable for non-battery materials, or should optional color/NIR/laser/XRF sensors be included in the base proposal?
a. We mainly want XRT, but if it fits within the cost to also have color/NIR/laser, we would also like to explore the option. Flexibility to add XRF later would be nice, but not completely necessary.
7. Does Argonne require access to raw detector data, corrected X-ray images, dual-energy maps, Z_eff maps, or only classification metadata?
a. Yes, access to all of the above would be the ideal case.
