This presentation is brought to you by Bushra Umer, our team member and volunteer from Batch - V, 2023. It highlights the significance of bioplastics, which outshine traditional plastics in sustainability and performance, paving the way for a cleaner, greener, and healthier planet. Considering the ongoing environmental crisis, there is an urgent necessity to embrace such sustainable solutions to rescue Mother Earth from environmental calamities. #Bioplastics #SustainableLiving #GreenRevolution #WorldEarthDay Youtube Link: https://youtu.be/LFpYs_4N_1k

2. Objectives of the study:
➔ To study the sustainable approaches to replace plastic.
➔ To understand the importance of biomimicry.
➔ To delve deeper into the charms of nanotechnology and
its potentials in developing eco-friendly materials.
➔ To understand the best ways to use biological resources
in cost effective manner.

★ Can be obtained from plants or bacteria.
★ Have abundant hydroxyl and carboxyl groups on the
surface, making it an ideal biopolymer matrix.
★ Possesses high strength and heat resistivity.
CNF:
● Naturally occurring silicate mineral.
● It is coated with TiO2 nanograins to give the
biomimetic effect (as that of nacre) and beautiful color.
● TiO2-mica is pretreated by APTES (3-
aminopropyl)triethoxysilane to facilitate interfacial
interactions between TiO2-mica and CNF

➔ Simple method to assemble the
highly ordered brick-and-mortar
structure directly.
➔ The main reason behind the
formation of sustainable and
eco friendly biomimetic
compounds.
Ca+2 Crosslinking
➢ Defined as linking of polymer and mica by
means of covalent bonds by the help of
Calcium ions.
➢ This step aids in the toughness and stability
of bioinspired plastic replacement.

cellulose nanofibers or CSF.
★ Bacteria-based bioplastics e.g,
Synechocystis and Synechococcus
species, model unicellular cyanobacteria,
can produce succinate and lactate, which
are commodity chemicals used to
generate bioplastics.
★ Agar

treatment) : Approx 83 MPa
(After treatment): 281 MPa
2. Mechanical property:
Flexural strength (The ability of the
material to resist bending without
breaking) : 175 Mpa

Conclusion:
Plastics are threat to the environment. By developing eco
friendly approaches using advanced but cost effective
technologies, we can fight with this issue, and can promote
the idea of making plastic replacements along with the
degradation of plastics.
