OUTPUTS: Benefits to forest health can be realized through development of innovative technologies and careful raw material selection in collaboration with forest managers. As forest and agricultural resource options change, and as waste-stream wood- and other natural bio-resources become available, as alternative non-wood materials become more economical and available, and as air and water quality regulations become more stringent, there is a need for us to address each of these issues. Research in this problem area focuses on developing information and providing service to public on how to use renewable material. FY 20 accomplishment includes: Comparing performance of cellulose nanofibrils and cellulose nanocrystals as flexible multilayer films for potential packaging applications; producing nanocellulose from hardwood; and transferring method for synthesizing graphene from encapsulated lignin particles. PARTICIPANTS: - FPL Staff and industrial partners - University of Wisconsin ⿿ Madison - Mississippi State University - Domtar Company - Ligwood Inc. TARGET AUDIENCES: Researchers, current/potential wood-based composite manufacturers, land managers, general public. PROJECT MODIFICATIONS: This problem area is fundamental and will be continued in our Research Work Unit Description. We will be reviewing and revising our Research Work Unit Description in 2021.
Impacts
The goals of this program are optimizing, both economically and environmentally, how we convert wood and woody biomass, reused or recycled biomass, and non-wood materials into durable, cost effective, high performing and long service-life products that are recyclable and otherwise environmentally friendly. To have the largest impact and address pressing needs, applications beyond traditional or emerging markets need to be developed. With suitable innovation in material, process, and performance development, novel composites with performance and functionality far beyond what is currently produced are possible. However, for the benefits of wood-based panels to be realized, research on new technologies and applications must be conveyed through new initiatives (e.g., green building), public outreach, technology transfer efforts, and interfacing with industrial leaders and user groups.
