    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.



    For more studies on SCG and Lignin, refer to the publications below:

    • Engineering Poly(lactide)–Lignin Nanofibers with Antioxidant Activity for Biomedical Application
    • Lignin-Incorporated Nanogel Serving As an Antioxidant Biomaterial for Wound Healing
    • Recycling of spent coffee grounds for useful extracts and green composites
    • Reinforcement of aligned cellulose fibers by lignin-polyester copolymers
