Two bulk samples of air dried rice husks, and corn cobs, as well as
a sample of starch were sourced and collected from local farms and
milling sites in Niger State, Nigeria. Rice husks were used as received
from the milling site, since they have a particle size of b2 mm, which
can readily undergo densification. The mass median diameter
(“D50”) of the rice husks was 0.7 mm.
