I compost them.
They also used slat water. You would think that they would do the same thing in Hawaii as they have a lot of both.
Whomever invents a way to separate garbage easily, where we dont have to separate anything and all the waste becomes reusable is going to become the wealthiest person on the planet.
Stop. End there. Next article.
"Inspiration for my research, from an Indigenous perspective, involves Caring for Country, ensuring there's a sustainable life cycle
Aww crap. I kept reading.
An organic product that will decompose over time. Will basically be aerated concrete which is already known to have limited lifetime.
You may want to consider keeping coffee grounds to burn in the winter for heat when the non-green power sources are completely phased out.
If climate freaks come for my coffee, I will not be--cannot be--held responsible for my actions.
As with the compost and roses fanciers' notions, we do both. A pot of filtered espresso a day provides a nice supply. I will garden today with them!
“…a staggering 10 billion kilograms of coffee waste”
You want staggering? I produce half of that all by myself.
It’s too much trouble
[[ “The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,”]]
The bs just never stops with those folks. The facts refute their ignorant claims- co2 isn’t anywhere near a large enough “greenhouse gas” to cause even a smidgen of movement o e way or the other climate-wise.
The pumice in the volcanic ash made the best concrete known to man. That is why Roman concrete has literally lasted 2000 years.
When I was a kid I remember my grand parents reusing the coffee grounds from the day before. They would add a little fresh coffee and a pinch of salt. They always kept their coffee in the fridge too.
So we need yet another container for coffee grounds to put out on trash day and we need to spend even more money for garbage removal. No thank you.
And pyrolizing the coffee grounds has no impact whatsoever.
I put them on my plants - get them from the local Starbucks that puts them in a basket for anyone to take. They are acidic so favorable for most plants.
Put several bags around my lemon tree before the last hard rain several months about - and the tree is now loaded with lemons.
Greenhouse gases such as methane and carbon dioxide. The coffee beans were carbon dioxide a year ago because the coffee plants make the beans from carbon dioxide in the atmosphere. The methane is from anaerobic decomposition but methane is way lighter than other atmospheric gases and rises to the top of the atmosphere before being carried away by solar wind. In other words, the carbon dioxide is not produced by coffee beans and the methane is only a temporary fleeting concern. Also, while carbon is the fourth most abundant element in the atmosphere universe, it is only the 14th most abundant element in the earth’s crust due to the fact that a lot has been lost over billions of years.
Coffee! Is there anything it can’t do?!
