This document summarizes research on developing a biodegradable polymer from potato starch. The researchers prepared powder starch from potatoes and used it to produce a biodegradable plastic. Biodegradable polymers were defined as materials that degrade when exposed to microorganisms. Such polymers have properties like good mechanical integrity, non-toxicity and ability to degrade in the environment. The researchers mixed potato starch powder with glycerin, acetic acid and water to produce a plastic sample. The bioplastic produced from potato starch has benefits like being environmentally friendly and easily degradable. The global biodegradable plastics market was estimated to reach $3.5 billion in 2020, with packaging materials being the largest segment

3. Biodegradable Polymer
 Biodegradable polymers are defined as materials whose chemical and
physical characteristics undergo deterioration and completely degrade when
exposed to microorganisms, aerobic, and anaerobic processes.
 These polymers are found both naturally and synthetically made, and largely
consist of ester, amide, and ether functional groups. Biodegradable polymers
are often used to reduce the volume of waste in packaging materials.
Example: Nylon 2–Nylon 6, PHBV.

11. Merits of Using
Biodegradable Polymer
11
1 Simply generated in our homes.
2 Production doesn't want any higher supervising.
5 Environmentally friendly.
3 More suitable than petroleum-based plastics.
4 Bio plastics don't cause any health issues
primarily.
6 Easily degrade into the soil.
7 Degraded by Bacteria present in Soil.
8 Bio plastic takes most probably 6-7 days to
degrade into the soil.
