Appendix XII
Water hyacinth composition percentage 2 %
C P Petioles 43.78
C L Leaves 17.68
C R Roots 38.54
The weight of the different parts of the plant, both
fresh and dry, were sought for in order to see how
many kilograms of each part could be obtained from
one square meter of water hyacinths. Due to the
variation of the areal density of the plant, a minimum
and maximum weight was calculated. This was done
with the following equations:
Wet Weight:
W P = ∂ * C P
Dry weight:
W P = ∂ * C P * 0.05

W PL Weight of petioles and leaves [kg/m 2 ] 24.58 104.48 1.23 5.22
After having weighed the Jani-pad, the number of pads
that would be able to be made from one square metre
could be calculated. The calculations were done with
the dry weight of the water hyacinth, as it is only the
solid matter of the plant that can be turned into paper.
Number of pads to be obtained from petioles per square
meter
N pad1 = W P / W pad
Number of pads to be obtained from petioles and leaves
per square meter
N pad2 = W PL / W pad
