I know sand is actually a precious resource when you really learn about how much concrete we make and what kinds of sand there are and which are needed for concrete.
But still, it’s strange to think that this exotic bean which will only grow in certain climates can actually be easier to get than fucking sand.
A biochar of spent coffee grounds.
Not coffee grounds.
If you don’t know what biochar is, it’s high carbon material that’s left over after burning organic matter (think:wood) slowly under low-oxygen conditions.
Biochar requires energy and emitting gases.
It seems unfair to say that we’re saving on CO2 and methane from decomposition without also counting the cost of the biochar combustion.
One time I got into a who-gets-the-parking-spot competition with another vehicle. I was faster and I got it. The other vehicle was a monster truck bigger than this one. As I got out and walked away I heard it’s h loud horn blare and a voice shouted “hey!” It was the guy in the monster truck. I walked over to him. He remained inside, rolled down the window. He was smallll. Like probably not quite 5 feet tall small. And in a little squeaky voice he said “aw man! I was gonna get that parking space, bro!” I just said “you mean that one where my car is?” and walked away.
Carbon negative when applied to soil. Making it is still a carbon releasing combustion process
EDIT okay I’m wrong they are including the production in their calculations.
