I like how the researchers thought, "hmm, I wonder what will happen if I mix my used coffee grounds with this batch of cement over here."

    Maybe they dropped old coffee grounds on their fresh concrete sidewalk while getting the trash out.

    I always have these kinds of thoughts when reading articles like this.

    On a serious note , I am pretty sure they find this stuff at the molecule level then match it to the closest item.

    This is an area where AI might actually be really useful in the future. If that's not already the case.
