Biodegradable bags are those types of bags that are capable of being decomposed by bacteria or other living organisms. Every year approximately 500 billion to 1 trillion plastic bags are used throughout the world (Aiken, 2009). Most bags that are manufactured from plastic are made from corn-based materials, for example, polylactic acid blends. Biodegradable plastic bags are nowadays as strong and reliable as traditional (mostly polyethylene)-bags. Many bags are also made from paper, organic materials, or polycaprolactone (Sam Wilder, 2006).

On 19th January 2020, a seminar was held in our department (Soil and Environmental Sciences, University of Barishal, Bangladesh) and an effective session regarding Biodegradable Materials was conducted by Mr. Saiful Paiker, A Navy Officer and Bio-Economist of Bangladesh. In the Youtube video, you may see that there was a biodegradable plastic bag in my hand that was brought by Mr. Saiful Paiker as a sample of biodegradable plastic bags. The bag is made from corn starch. If we dump the bag in soil, that will be decomposed within a very short time. On the other hand, if we dump the so-called plastic bag in soil, that will take many years to be decomposed, even more than 400 years can be taken to be degraded. I hope, the research, implementation, production, and use of Biodegradable Materials will be extended in our country, Bangladesh as well as throughout the world.
