Cellulosic biomass operations require an extensive evaluation of availability, the harvesting and collection of the resource, and the means of transportation. These tasks demand significant time and complex research. Cellulosic biomass resource information is often limited, diffuse and difficult to obtain. Comprehensive, coordinated, and user-friendly sources of information are required. The BioSAT web-system allows you to assess logistical opportunities and create cost curves for cellulosic biomass supply.
