For briquetting tests, sufficiently mature dry soda weeds
were collected from the fields within the university campus,
then the weeds were chopped with a local thresher having
finger type beater. Chopped materials were screened using
a sieve of 10 mm diameter. Because approximately half of the
materials were greater than 10 mm size, these materials
consisting of firm fractions of the weed were further processed
in a hammer mill with 6 mmsieve. Resulting materials
obtained from both the thresher and the hammer mill were
mixed homogenously and used for briquetting.
