Obtaining biodegradable films through the management of organic waste containing starch and chitosan

In this research work a biodegradable polymer
is obtained from the mixture of potato starch with chitosan,
obtained from the squid pen. The proportion of chitosan and
starch was investigated by mixing different weight
percentages of starch and chitosan, to determine the
mechanical characteristics, such as the tensile and
biodegradability test.
Starch films and chitosan films were prepared to evaluate
their mechanical properties separately from which a
maximum result of 10.17 MPa for starch films and 46.766
MPa for chitosan films was obtained. While the starchchitosan compound had a maximum resistance of 24.59
MPa. With these results we can indicate that starch improves
the properties of chitosan films. The mechanical properties
of the starch-chitosan compound is superior to that of some
conventional plastics, such as in comparison to low density
polyethylene having a resistance of 17.3 MPa.
