You can do so much more with coffee other than drink it. Here are 6 other things to do with this common beverage



Every day, more than 2 billion cups of coffee are consumed around the world, and the basic material for making coffee is disposed of in landfill, which is estimated at around 6 million tons annually.


This is definitely harmful to the environment, as the decomposing coffee waste releases methane into the atmosphere, which is the second most prevalent gas in greenhouses and the cause of global warming with more than 86 times that of carbon dioxide.



In this article, we will show you five ways to reuse coffee waste:


1. Biofuels


If you leave your coffee cup for a while, you will notice the appearance of a shiny layer on which this layer appears, which is a group of oils in the coffee beans, of course, this amount of oils is not all the oils in the coffee, but large amounts of these oils are disposed of during the coffee brewing process. These natural oils can also be extracted from coffee and used as a biofuel, as in a recent experiment in the USA (US chain Dunkin 'Donuts) developed a subsidized and fully functional small home based on biofuels from coffee.


As these natural oils found in coffee are mixed with alcohol and subjected to a chemical reaction known as the transesterification process. The result of this process is biodiesel consisting of 80% of coffee and 20% of alcohol, in addition to glycerin as a by-product of this process. Biodiesel is also cleaned and purified and used as a final product through its use to generate electricity.



2. Capturing greenhouse gases


Instead of sending coffee to landfill sites, which in turn analyze the coffee and produce methane for the atmosphere, scientists have found a method that can store carbon dioxide and methane from the coffee waste.


A research published in the Institute of Physics’ Nanotechnology journal shows that heating coffee grounds with potassium hydroxide produces a substance that can store methane gas. This material from coffee processing can store more than 7% by weight methane gas and is stable at normal room temperature.



3. Use it as a natural fertilizer


One of the best ways to recycle coffee is to use it as a fertilizer, and many public cafes offer free coffee residues for users to reuse and recycle as a natural fertilizer for gardens.


It should be noted that recent studies show that to compost coffee residues, it is necessary to leave them for at least 98 days before applying them to plants. Because coffee contains high levels of caffeine, chlorogenic acid, and phytotoxic tannins.



4. In industries as a basic material


Coffee is now used as a building material used in the manufacture of furniture. Re-Work, which produced Curface: pronounces like Surface, is a composite material made from used coffee scraps and recycled plastic.



5. Children's games (Lego blocks)


The Japanese company (Color Tokyo) manufactured brick-like Lego bricks made of sawdust, cedar wood, tea leaves, and coffee grounds. Unfortunately, these Lego blocks are only available in certain colors and are somewhat faded, and a set of 50 pieces costs $ 30.


6. Clean hair


In addition, the fact that coffee is rich in natural compounds, oils, potassium and nitrogen, coffee contains a strong composition that can make it a substitute for various products at home!


It can be used to clean and treat hair from the chemicals that make it weak. Especially for people who use hair styling
