A biodegradable polymer is a type of polymer that, when used for its intended purpose, breaks down into by-products such as carbon dioxide, nitrogen, water, biomass, and inorganic salts with the help of bacteria. These polymers are found both naturally and synthetically made with help of polyester. Fillers and other polymers can enhance the mechanical properties of biodegradable polymers.
In recent years, there has been an increase in interest in biodegradable materials for their practical applications in packaging, agriculture, medicine, and other sectors in India. In medicine the biodegradable polymer is used as:
Surgical sutures– A growing market for biodegradable polyester fiber (monofil) is in resorbable surgical sutures, which slowly dissolve and do not need to be removed afterward.
Medical wipes– Biodegradable yarn/fibers are also used for disposable items such as wipes and are super are environmentally friendly.
Tissue engineering– Polylactic acid fiber (PLA) silk is used as an implantable suture and as a scaffold for ligament tissue engineering.
Orthopedic fixtures– When implanted, these fixations gradually break down in the body after healing, so a second surgery isn’t necessary.
In addition to medicine, biodegradable polymers are often used to reduce the volume of waste in packaging materials. This represents an important step in replacing materials derived from petrochemicals with biodegradable materials.
