After drinking that coffee, we ask you: what do you do with the coffee grounds left in the strainer? If you are throwing it in the trash, then we have a lot to talk about.
And do you know why? Coffee grounds can be used for many things, from aesthetic treatments to plant compost.
We will tell you all of this (and a few more things) below, follow along.
Why reuse coffee grounds
According to data from the Brazilian Coffee Association, ABIC, we Brazilians consume no more, no less than 1 million tons of coffee per year, which is equivalent to 4.8 kg of coffee per person, on average.
It is no wonder that we are the largest coffee producing country in the world and the second largest consumer market, second only to the United States.
The result of all this consumption is the annual production of about 800 thousand tons of coffee grounds. And do you know where it all ends up most of the time? In landfills and dumps.
And this is an environmental problem that impacts the whole of society. The coffee grounds when decomposed in these places generates methane gas, a highly toxic and harmful gas to the ozone layer, 20 times more polluting than carbon dioxide.
Coffee grounds are rich in nutrients that can be used by our skin and hair. But it is not limited to that!
This leftover coffee from every day is still very beneficial for plants, for cleaning and deodorizing the house and even for your pets.
This is because coffee grounds contain nutrients such as caffeine, a natural stimulant, as well as lipids and phenolic compounds that, among other things, guarantee the typical color and aroma of coffee and still work as an astringent.
This combination of substances makes coffee grounds an excellent ally in the home for the most diverse functions.
