What is the purpose of this question? Do you want to know about the technique and technology involved or do you want to research on the social factors involved in the consumption of bioplastics?

Thanks for reply. I am willing to know how to synthesize and characterize it.

Hello Sunil,

It is a broad question and the answer could be very general. bioplastic as you know can be based on natural polymers such as lignin, protein, natural rubber, polysaccharides and other sources (e.g. cyanophycins).

talking about vegetables I think would come under polysaccharides and lignin, which then divide into structural PS such as cellulose or storage PS such as starch. to make starch based plastic, the strach crystals need to be destroyed and gelatnise, because you eventually want a melt processable material. there are methods such as jet cooking or extrusion to do this task. re cellulose also there are many details such as cellulose crystal and molecular structure, degree of polymerization and so on. there are techniques such as vicose, carbamate, Lyocell and sodium hydroxide to dissolve cellulose and regenerate it in the form of fiber. Please narrow down your keywords and you will find a lot of information to read.

Dear Sunil Kumar,

By considering your question which is quite general, I suppose that you need a first/preliminary information (about main biopolymers, production, properties and commercialization).

I assume that some books, chapters or Reviews will help you, thus I will give only some selected examples. However, the terms "bioplastics" and "biodegradable plastics" have been used interchangeably, but there are important differences between the two categories of polymers. Bioplastics - such as polylactide (PLA), thermoplastic starch (TPS), polyhydroxyalkanoates (PHA), polybutylene succinate (PBS), bio-polyamides, bio-polyethylene, etc., are polymers that are made from renewable resources, such as food crops or biomass. Some of these bioplastics, but not all, are also biodegradable. Even that a generally recognized definition of the concept “biopolymers/bioplastics” does not exist, generally it is accepted that they are mainly as follows: (a) based on renewable resources and biodegradable; (b) based on renewable resources but not biodegradable; (c) based on fossil resources and biodegradable. Please consider bellow some pieces of information...

Good luck and best regards,

Marius
