This is very cool actually! Human bodies take so many resources from the Earth to grow, the very least we can do is recycle what's left when we die. Body composting ("green burial") is an increasingly popular option today, but I wouldn't mind if my bones were used in manufacturing either. (Actually my biggest objection would be who's profiting off my bones. I've spent almost my whole life so far enriching billionaires, and it would be cool if that could end at my death.)

I think what's most surprising to me is that I didn't realize battlefield mass graves were actually so common in the past. At this scale it makes sense, but I had an idea from antiquity studies that war dead were expected to be brought home for burial. (That could also be untrue of antiquity tbh; burial was always an incidental topic.)
