Scientific studies: drinking coffee saves the planet
- Every year around the world, 6 million tons of coffee grounds are landfilled where they ferment and emit a greenhouse gas, methane which is "25 times more powerful than carbon dioxide".
- Although coffee is a superfood rich in antioxidants that reduces the risk of cancer, diabetes, Parkinson's and a number of other health problems, it is considered one of the main causes of climate change.
- After a great effort, scientists have found ways to recycle used coffee, which is consumed by millions around the world and considered one of their favorite morning and evening drinks.
- Recently, three of the most important studies that have resulted from these efforts have emerged, the first of which was the Royal Institute of Technology in Melbourne in 2021 that found that coffee grounds could reduce a building's carbon footprint.
- It was published in the study that the used coffee residue has an initial use as a building material aggregate that is widely used in civil engineering applications. In a related context, a recent study this year conducted by Tianjin Shengjian University of China revealed that coffee grounds produce very pure water. The study pointed out that used coffee residues are very effective in removing pollutants in wastewater.
- She said, "In order to produce ultra-pure water, the results showed that the catalysts and the oxidizer have a very effective effect." And third, a study by Turkey's Erciyes University this year also reported that coffee grounds can be a highly effective biofuel.
- She wrote, "The merging with bio-refineries in general, and the pyrochemical process in particular, is one of the most successful solid waste management strategies for used coffee grounds."
