Spent Coffee Grounds: From Food Waste to Bioplastics

While you sip on your morning cup of coffee, learn a little-known fact about the Spent Coffee Grounds (SCG). They contain various functional compounds, such as lignin, a polymer with excellent anti-UV, antioxidant and antibacterial properties. See how IMRE scientists explore the endless possibilities of upcycling these food waste and convert them into bioplastics that can replace petroleum based plastics.
