Eco-friendly Biodegradable Polymers

What are eco-friendly biodegradable polymers?

The polymers which give no bad effects on the environment and degrade ultimately into the environment by interacting with microorganisms of the environment are called eco-friendly biodegradable polymers.

 Reasons for concentrating on biodegradable polymers:

Polymer s has been used for different purposes for years. But there is a huge load of waste management after dumping polymeric materials into the environment. In view of the polymeric waste management, scientists have concentrated on eco-friendly biodegradable polymers. Polymer researchers had been trying to make degradable polymers for years. From this perspective, they are focusing on natural polymers that are degradable. Along with the search for natural polymers, they are also trying to make synthetic polymers degradable by converting higher molecular weight polymers into lower molecular weight polymers. These polymers will be eco-friendly biodegradable polymers.

In recent years, there is a wide scope of polymer discussion that is the biodegradable polymer. Biodegradable polymers have emerged as a promising candidate for a wide variety of applications.

For example, they have major applications for biomedical applications, packaging’s as well as food supplements etc. That’s why scientists have emphasized on the promotion of bioproducts made from biodegradable polymers.

Classifications of biodegradable polymers:

Biopolymers can be classified in two ways: according to their renewability content (fully or partially bio-based or oil-based) and to their biodegradability level (fully or partially or not biodegradable) [Shen et al 2009]. An attempt to classify biodegradable polymers into two main groups has been developed [Averous 2004], these two groups being -(i) the agro polymers obtained by biomass fragmentation process (polysaccharides, proteins..) and (ii) the bio-polyesters obtained either by synthesis from bio-derived monomers (polylactic acid-PLA) or by extraction from microorganisms (polyhydroxyalkanoate-PHA) or by synthesis from synthetic monomers (polycaprolactone-PCL, aromatic and aliphatic copolyesters-PBAT, PBSA…).

About Md. Shafiul Islam

I have been working as an Assistant Professor since May 26, 2015.My research profile lies at the interface of biomaterial science, life sciences and engineering. I am particularly interested in the design of bionanocomposite materials for relevant clinical applications, e.g. in the context of fabricating and testing biocomposite materials to study the biocompatibility with human body to repair bone tissue. I joined as a lecturer at Noakahli Science and Technology University in May 26,2013. During my working as a Lecturer, I did research on waste water treatment. In connection to this, I applied nanotechnology to treat water as well as waste water. Prior to joining the Noakhali Science and Technology University , I joined as a Scientific Officer in Drug & Toxins Lab as well as Polymer Chemistry Lab at Bangladesh Council of Scientific & Industrial Research (BCSIR).Before doing scientific works, I did M.S. thesis work in the Institute of Polymer & Radiation Technology. I completed my undergraduate studies in Applied Chemistry & Chemical Engineering ( University of Dhaka, Bangladesh) and gained my M.S. in the same department, under the supervision of Professor Dr. Mohammed Mizanur Rahman (University of Dhaka, Bangladesh), where he investigated the effect of reinforcement of nano-materials into bio-polymer composite, morphology and the effect of bacteria in the bio-composite. . I achieved Dean's Award in recognition of my excellent academic and oerall performance in B.Sc. In Bangladesh,I was shortlisted for National Science & Technology (NST) Fellowship and was successful in securing funding from Ministry of Science & Technology, in collaboration with Professor Dr.Mohammed Mizanur Rahman, University of Dhaka, towards the manufacture of medical devices that are resistant to microbial colonization. I have authored 6 research papers and 1 conference paper (h-index: 2).
