Coffee is one of the most popular beverages in this world. Have you ever imagined how many cups of coffee people around the world drink for each day?
We consume almost 2.5 billion cups of coffee a day !!! For every 100 grams of coffee we use in coffee machine, 91 grams of wasted ground coffee are generated. It is estimated that 32,000 tons of coffee we consumed per year. That means there are around 29,000 tons spent coffee grounds per year. [1]
We can recycle those spent coffee ground by feeding plants, chasing away snails, ants and cats, removing bad odors in your refrigerator or even scrubbing your face & body but basically most people just dumped those spent coffee grounds into garbage bin and sent to landfill where they emit methane being a greenhouse gas 30 times more potent than carbon dioxide and one of the primary causes of global warming. [2] However, many researches found that the potential in those spent coffee grounds containing 18% oil can be an eco-friendly, alternative feedstock for biodiesel. [3][4][5]
Last Feb 2020, KLM Royal Dutch Airlines and Lavazza (an Italian manufacturer of coffee products) just signed an agreement on creating the sustainable aviation fuel on a large scale which can reduce Carbon emissions by up to 85% compared to fossil fuels. [6] We can't wait to see the progress of their cooperation in aviation biofuel from coffee in the near future !!!
