#Coffee Grounds

[mindblowingscience]

We could be producing concrete that's 30 percent stronger by processing and adding charred coffee grounds to the mix, researchers in Australia discovered. Their clever recipe could solve multiple problems at the same time. Every year the world produces a staggering 10 billion kilograms (22 billion pounds) of coffee waste globally. Most ends up in landfills.

"An estimated six million tonnes of used coffee grounds are created annually. Most go to landfill, generating methane and CO2, or are incinerated for energy.

It’s an obvious waste of a byproduct still rich in compounds (if not flavour). On a domestic level, try directing your cafetiere contents to your garden, not your bin: used coffee grounds are excellent as an addition to home compost bins and wormeries, a mulch for roses and a deterrent to snails. And on a global scale, science might have the answer.

A new study in the Journal of Chemical Technology and Biotechnology suggests that used coffee could hold the key to a pressing environmental problem: agricultural contamination.

How could old coffee grounds solve agricultural pollution?

Scientists from Brazil’s Federal Technological University of Paraná found that leftover coffee can absorb bentazone, a herbicide frequently used in agriculture.

When old coffee grounds are activated with zinc chloride, their carbon content becomes 70 per cent more efficient in removing the herbicide.

The study’s tests involved bentazone dissolved in liquid and treated with activated carbon from used coffee grounds, to see how it affected onion root tissues called meristems. All plants grow from meristem tissue and a plant’s development is disrupted when its meristems are damaged.

If the test can be replicated on an industrial scale, it would be an environmental double whammy: diverting coffee waste from landfill and preventing damage to wildlife and nature from herbicides.

Why is bentazone a problem?

...The UK’s Environment Agency cites bentazone as having the potential to affect long-term water quality and lead to an increased need to treat the UK’s drinking water sources. The herbicide has been shown to impact human health if it is inhaled, ingested or absorbed through the skin.

While this is only preliminary research and more studies are needed to determine efficacy of activated coffee grounds on a global scale, it’s a promising start. The authors of the study say their results “suggest a circular economy solution for spent coffee grounds that are currently discarded without any recycling or reuse system”. We can all drink to that."

⏳📘☕ (late) Day 4 of @deadboystims's 300-follower event: my favorite book right now is Before the Coffee Gets Cold by Toshikazu Kawaguchi :P

God, I recently finished this book and it's SO good. I have no words to explain it, just trust me. The character writing was my favorite part, but I always just pay close attention to how characters are written over anything else subconsciously...I don't know why. But I still thought the idea and plot of the book was cool!

And yeah...I don't care for horror movies...so I did this :-) I'm not a wimp or whatever, I swear, I just don't really care for them!

Having a normal one over this scene as one does. The way they’re like swaying and the simple “I'm here for you” “I know” is just everything to me.

One of my neighbours came over today. She's not a gardener but knows I am. She said she now has a home coffee machine and it generates coffee ground waste. This picture is a week's worth. She wanted to know if I would like the grounds for my garden.

So I will now have my own regular little supply of coffee grounds. Yay!

The Deception of SDGs (prose)

I've been hearing the term Sustainable Development Goals a lot lately. As a word, sustainability and its opposing concept of development coexist in one word. On the TV show I watched yesterday, a consumer was featured who said, "I recycled coffee grounds." ...But this is a deception. They are just self-satisfied that they have done something environmentally friendly by recycling this kind of thing. These people are the ones who use flush toilets without any doubts. This is the problem.

Flush toilets are one of the worst things humans have ever invented. They contribute to environmental pollution without taking any responsibility for their own waste. In that sense, SDGs are a stone in the sand. Composting toilets are better than flush toilets. Disposing of feces and urine probably impacts the environment more than kitchen waste. A senior of mine from university, a sanitary engineer, used to work for the United Nations. Still, when it came to water treatment, he was doing work reminiscent of flush toilets. This won't do.

SDGsの欺瞞（散文詩）

Sustainable Development Goals（持続可能な開発目標）という言葉で、最近よく聞くようになった。言葉としては持続可能ということと、それに相反する開発ということが、ひとつの言葉のなかに共存している。昨日見たTV場組では、「コーヒーの搾りカスをリサイクルしました」、とかいう消費者が取り上げられていた。・・・でも、これは欺瞞だ。この種のリサイクルをやって、なにか環境に優しいことをやったと、自己満足に浸っているに過ぎない。こういう人に限って、水洗トイレをなんの疑問も抱かず使っているだろう。ここが問題なのだ。

水洗トイレは、人間が発明したものの中で、最悪のものの一つだ。自分の出した排泄物に、なんの責任も負わずに、環境汚染の片棒を担ぐのだから。SDGsは、その意味で、ツマズキの石である。水洗トイレではなくコンポストトイレのほうがまだマシだ。厨房ゴミより糞尿の処理のほうが、環境に与える影響が大きいだろう。大学の先輩の衛生工学者は、国連で働いていたが、こと水処理では、水洗トイレをイメージした仕事をやっていた。これではダメだ。

All right, who reads coffee grounds someone read these and let me know what they say

How the hell do you do it.

I need coffee!
