With the rising awareness of environmental protection, more and more countries are implementing plastic restriction policies. Australian scientists have recently come up with a way to convert coffee grounds into coffee cups so that coffee residues can be recycled.

According to the comprehensive report, Australians consume 6 billion cups of coffee a year, producing nearly 3000 tons of coffee grounds each year, and usually 93% of the waste ends up in landfills. But scientists at Macquarie University University in Australia recently came up with a way to turn coffee grounds into coffee cups. The team successfully converted the most abundant mannose in coffee grounds into lactic acid, which can be used to make biodegradable plastics and then make environmentally friendly coffee cups.

And this kind of decomposable plastic made from coffee grounds can not only be used to make cups, but also can be made into all kinds of products, from beverage containers, composting bags and other household items to sutures for medical surgery. At present, scientists are trying to increase the conversion of lactic acid so that coffee grounds can be used more effectively.
