How To Use Coffee Grounds To Produce Biodegradable Plastic
At Macquarie University in Sydney, Australia, Dominik Kopp, a Ph.D. student, has developed a method for turning coffee waste into biodegradable plastic coffee cups. Because of its properties, sugars are an efficient source that is often converted into biobased chemicals. According to this study, coffee grounds consist of 50 percent sugars that can be converted into lactic acid. Once this is done, lactic acid can be used to produce biodegradable plastics. “You could use such plastics to make anything from plastic coffee cups to yoghurt containers to compost bags to sutures in medicine,” Kopp highlights.
