Researchers discovered that waste from your morning brew could revolutionize construction materials, making concrete dramatically stronger while solving a global disposal crisis.
The wrong “shape”. That is a misnomer and only matters to some applications. And even that is easily overcome by an added manufacturing step that would arguably be a lot easier than collecting/baking coffee grounds.
The silica is not going anywhere. In concrete and silicone, it is recapturable and re-usable.
Add on to that, the amount of used coffee grounds don’t even come close to making any impact at all.
Sure you can replace 15% of sand, in a mix, with these grounds, but good luck finding enough grounds to even cover that for one building.
Uh, more than half of the earth’s crust is made from silica.
How are we running out?
Coffee grounds are better used in compost. Less work and takes advantage of its actual content.

Should I trust BBC or a random dude from the internet? It’s a hard choice.
I don’t give a shit if you trust me or not.
You shouldn’t depend on either of us. If it’s important to you, do your own fuckin research.
Someone shows up that disagrees and your like, “I don’t know who to believe!”
FFS, you are part of the problem. Grow a fucking spine.
Yeah im part of the sand problem. Lol
I’m going to trust the bbc on this one sluggo.
