The University of Tennessee, Knoxville, is part of the BRIDGES Engine team that has won up to $160 million from the U.S. National Science Foundation (NSF) over 10 years. One of only 12 winning proposals selected from 300 pre-proposals and more than 70 full submissions, BRIDGES targets a major regional gap in advanced technology investment. The program is designed to convert research momentum into sustained economic outcomes for rural communities across Tennessee and Alabama.
BRIDGES will repurpose underutilized farmland by establishing specially developed perennial grasses and then upgrading the resulting biomass into biobased materials and finished goods. These outputs are aimed at high-demand markets including automotive components, construction products, and packaging. Instead of treating crops as a single-use commodity, the project emphasizes multi-application product pathways to improve market resilience.
From a technical standpoint, the initiative advances the full “farm-to-product” cycle. It supports research and development, commercialization planning, and scaling strategies, while building workforce capacity for technical, agricultural, and manufacturing roles. The goal is to create biomanufacturing pipelines that can operate reliably beyond early pilots and transition into durable supply chains.
UT highlights that biobased manufacturing is a long-term institutional strength. The award leverages an earlier $20 million, five-year investment involving UT and Oak Ridge National Laboratory initiated in 2024, intended to accelerate circular bioeconomy innovation. BRIDGES builds on this foundation to strengthen downstream conversion and integration with industry needs.
The coalition is led jointly by the University of Tennessee, HudsonAlpha Institute for Biotechnology, Auburn University, AGgrow Tech LLC, and long-standing UT partner Volkswagen Group of America. Volkswagen serves as a co-lead and brings industry requirements early, supporting the development of biobased materials aligned with real manufacturing constraints and product performance targets.
According to project estimates, BRIDGES could generate tens of millions of dollars in additional annual income for regional farmers. Bioproduct manufacturing is also projected to attract more than $2 billion in private capital investment and create thousands of higher-paying jobs across manufacturing and supply chains. More than 10,000 participants are expected to engage in workforce development and training activities.
NSF’s Regional Innovation Engines competition was created to spur transdisciplinary collaborations in areas that have not benefited significantly from recent tech booms. BRIDGES responds directly by connecting agricultural research capabilities to industrial commercialization and scaling efforts.
Tennessee’s support further strengthens the plan: the Tennessee Department of Economic and Community Development awarded $10 million from the Federal Innovation Grant Matching Fund to help the initiative compete for transformational federal investment. Together, the public-private framework is intended to make the innovation ecosystem self-reinforcing and locally rooted.
The BRIDGES network includes 85 collaborators spanning academia, stakeholders, commercialization partners, and industry. With 18 academic research institutions and 42 industry partners ranging from startups to established corporations, the engine model aims to keep research relevant while accelerating translation into deployable biobased products.
