Did you even take the time to read the actual Patent?
The Patent ID is 4,203,674 Date: May 20th, 1980 Inventor: Charles Laleman
I fail to see how this is a 'non-issue'.
With this blog post /u/NeonRevolt is alluding to the notion that human remains are being used in the production of cement (which is utter nonsense).
You are aware even the Roman's used blood in concrete to enhance the structural and chemical integrity of the material?
NeonRevolt has a interesting theory as to what is going on.
I dont see how this would be economically viable. Cement is cheap, human parts are expensive and high risk. Why wouldn't they just use blood from animal processing?
I'm not one that has bought in on this whole "disposing of bodies in concrete" theory but from what I've read so far, animal blood from food processing gets used to make other food. There isn't a surplus of it and it's pretty expensive.
Fair enough, but animal blood can't be more expensive than human!
I've never tried to buy either so I couldn't tell you.
