Sand is a big problem because we are slowly running out of it. And transporting suitable sand takes a lot of ressources, minimizing the use is good.
Plus why can't we tackle two problems at once?
The greater point I'm getting at is whatever aggregate you use to make more concrete, making the concrete with Portland is still 8 percent of CO2 emissions. You can protect local environments and maintain concrete production, but what use is that when you're cooking the planet with the concrete in the first place? Gotta stop liberating the CO2 from rocks, not green wash it.
Why is there CO2 in rocks why are they breathing

Okay yeah this is true.
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.

That article is sensationalist.
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.
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.
