I have a suggestion but am not a Lego guy. Maybe you can do a few things now that the sorter works, potentially using it to automate or minimize order fulfillment.

The idea is that if you can get a dataset of Lego packs / models you can use your inventory to make them. You can offer sales of the kits based on dynamic info. You can also provide inventory dynamically to users to purchase parts or upload a build manifest which will be filled.

I think the 2 huge assets you have are sorting for processing AND fulfillment, and real-time inventory levels of verified authentic parts.

Also, I would make some sort of contest, auction fun game where a person can win the whole pile of discarded stuff. Idk what's in there but I bet someone would want it.
