The Feedstock Logistics team works on developing systems and strategies to enable sustainable and economic harvest, transportation, and storage of feedstocks. The team focuses on the development and evaluation of harvest and logistics systems that are easily adaptable, produce consistent and quality feedstock for conversion, and are economically, energetically, and environmentally efficient and sustainable.
The team is also investigating novel harvest and transport systems, demonstrating these systems at field-scale, and evaluating harvest and supply chain costs. The team also evaluates technologies for more efficient feedstock de-construction and drying.

Feedstock Logistics Resources
Our Feedstock Logistics team members have produced an extensive resource library with material for everyone involved in the harvest, storage and transportation of perennial grasses. Check out our Fact Sheets (3), Peer Reviewed Journal Articles (12), Instructional Videos and Webinars (3) and Frequently Asked Questions (4).
With project partner eXtension we have created an overview of our work in feedstock logistics: CenUSA Feedstock Logistics: Innovative Systems for Harvest, Transportation, and Storage of Perennial Grass Biomass. (Jan. 2017).
- Kevin Shinners (Agricultural Engineering, University of Wisconsin) explains the rationale behind best practices & equipment for harvesting perennial grass biomass.
Storing Perennial Grasses Grown for Biofuel (July 2015)
- Kevin Shinners explains that no matter how you store harvested perennial grasses grown for biofuel feedstock, be sure to minimize dry matter losses and maintain uniform physical and chemical properties.
- Stuart Birrell (Ag & Biosystems Engineering, Iowa State University) and Amy Kohmetscher (Distance Education Specialist, Agronomy and Horticulture, University of Nebraska-Lincoln) show there’s more to producing a crop like switchgrass for bioenergy than just growing it.
