Session 5: Wood-based Foams and Packaging Films

Wednesday, November 4th • 11:00am – 12:00pm

Session Chair: Sudhagar Mani, University of Georgia

Strong, Lightweight Lignin‐based Foams

Technical lignin is obtained as a byproduct of the pulping process. Most technical lignins are burned for energy generation in the mills, with only 2% of the total production being used as value-added products. The intrinsic properties offered by lignin e.g. high stiffness, resistance to moisture and fungus, can potentially be exploited for use in packaging foams or insulating materials. However, foams made of lignin alone lack structural integrity and mechanical strength mostly due their low molecular weight and rigid structure.

Attendees will learn how combining lignin with cellulose nanofibrils (CNFs) i.e. nanosized cellulose particles obtained by high-shear mechanical treatments, can create composites useful as foam materials.
