whats the reason for using titanium dioxide in bioplastic if it is costly? is there any reason to justify it ???
TiO2 is NOT that expensive compared with other metal oxides with similar properties. It is used in several white paint, coatings, inks, sun screen blocker, toothpaste and so on. Actually, almost everything that has white color employs titanium dioxide in its composition. It is a balance between properties and cost, and TiO2 is one of the best ceramics that are in our day-to-day basis.
"As a ripple effect, the CFR USGC discussions for Titanium Dioxide Rutile grade settled at USD 3840 per tonne in March 2022" So it is around 3.84 USD per Kg of TiO2. Cheaper than McDonalds.

Gustavo Henrique de Magalhães Gomes if the synthethic plastic is cheaper then why someone else used this bioplastic with an such expense .. suppose if the price of synthetic plastic is 1dollar and the bioplastic which are made from gelatin and TiO2 sales 3dollar then why would someone buy this
@Maham Khan bioplastic is biodegradable, so people pay more to reduce the threat to the environment. There are a lot of non-biodegradable plastic wastes in the oceans, a lot of microplastics in surface water and soils. It is significant ecological problem.
