  Microalgae can be used in the packaging sector due to their ability to
synthesize bioactive compounds that are favorable in the production of
biodegradable packaging. In this work, to create an alternative to plastic
packaging, we studied microalgae Chlorella in the presence of k-Carrageenan to
form biodegradable packaging using various approaches such as gel formation,
film creation, and photometric analyses. Here we have measured Gel-Sol and
Sol-Gel energies by employing Arrhenius Law on photon transmission curves,
produced during these hysteresis-type phase transitions. The combination of
Chlorella, k-Carrageenan, NaCl, and water could form a gel that had a high
biodegradation rate with no photodegradation obtained from the experiments. At
the same time, our findings indicated that the material obtained from these
processes could be a considerable option that degrades much faster than
plastic.
