When individual organic molecules are joined together in long chains, polymers are formed which have distinctly different characteristics in comparison to the smaller starting materials. The most important bio-polymers are DNA and RNA, proteins and polysaccharides. The building blocks for these molecules are respectively nucleotides, amino acids and carbohydrates

•  Biomolecules
• Polynucleotides
• Monomeric
• Polysaccharides
• Polypeptides

Degradable plastic are plastic materials produced from sustainable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. Some bio plastics are obtained by processing directly from naturals.

Degradable plastics and its applications:

• Packaging
• Food-services
• Agriculture/gardening
• Consumer electronics
• Automotive
• Consumer goods and household appliances

Advanced thesaurus method composite materials have obtained popularity in high-quality structure applications such as automobile, marine, and aerospace structures.

• Molecular design technique to combine  advanced thesaurus for use in electronic devices
• devices such as solar cells and natural field-effect transistor
• The applications of advanced thesaurus or related composites used in electric devices such as solar cells and natural field-effect transistors
• Fundamental mechanisms of the application of Advanced thesaurus  method  composite materials have obtained popularity in high-quality structure  applications such as automobile, marine, and aerospace structures.

This is human-made polymer Nylon and polyethylene are two famous example of synthetic polymer. The polymers which can be formed with the aid of linking monomer gadgets, without the any trade of fabric, are recognized to as addition polymers or additionally called as chain-boom polymers.

• Synthetic fibers
• Elastomers
• Vulkanization
• Inorganic polymers
• Bakelite

Bioplastics are used as alternatives to standard fossil fuel based plastics and are increasingly more being used in meals contact materials (FCMs).Biomass used for the production of bioplastics may be extracted from plant life (starch, cellulose) or produced by using microorganisms in fermentative processes. It is able to also be produced by further chemical changes and aren't always biodegradable.

• Oxidation
• Rancidity
• Enzymatic browning
• Carbon footprint
• Carcinogenic

In the modern era, there's a burgeoning call for easy, pollutants-unfastened environment and excessive urgency for minimizing fossil fuel. This ends in an increasing call for manufacture of excessive performing cultured products from organic and renewable resources. Polymer biocomposites are the precise exchange to fulfil such alarming urgency. Those have residences of high mechanical resistance, thermogravimetric, oxygen barrier, biodegradation and chemical resistance. There may be no single material that could obtain such huge variety of residences for which layout of composites, mainly with biopolymers, is an strive for significant improvement of residences. The biopolymers can be functionalized for higher compatibility throughout guidance of composites.

• Natural fibers
• Cellulose fiber
• Green composites
• Hybrid composites
• Biorefinery
