according to the needs of the conversion plant. Secondary compression of the
pelletized biomass may be an option to reduce the porosity and increase the bulk
density.
6. The transportation between the CSP and the conversion plant takes place in rail-
car containers for bulk goods. The traffic flow between the CSP and the conver-
sion plant is continuous, similar to current processing plants where a fixed
number of railcars arrive daily, eliminating the need for long-term storage at the
conversion plant. At the conversion plant, the pelletized biomass is dumped in a
large collection bin, after which the pellets can be either mechanically crushed or
dropped into a liquid for pretreatment.
