Application

• This project offers a sustainable alternative to plastic by using avocado peel fibers to create biodegradable packaging materials. It could help reduce plastic waste and provide eco-friendly solutions in various industries.

Description

Researchers at South Dakota State University, led by Srinivas Janaswamy, are exploring the use of avocado peel fibers to create biodegradable films as an alternative to plastic. The films, made from cellulose extracted from avocado peels, are strong, transparent, and biodegradable within 30 days. This innovative material offers a potential solution to plastic pollution and food waste. The team is continuing to improve the properties of these films for broader application in sustainable packaging.

Pathway Description:

The process starts with extracting cellulose fibers from avocado peels, which are about 28% cellulose. These fibers are processed into a powdered extract, which undergoes a "green" chemical modification to improve its properties. The modified cellulose is then used to create transparent, strong biodegradable films. These films are designed to degrade within 30 days when exposed to soil moisture, offering a plastic alternative.
