Straws made from mango peelings are biodegradable

More than fifty million tons of mangoes are grown annually worldwide, but until now, their shells are often abandoned or used very rarely.

More than fifty million tons of mangoes are grown annually worldwide, but until now, their shells are often abandoned or used very rarely. Two college students in Mexico won the top spot at the university science fair with an innovative method of turning fruit peels into biodegradable straws.

Straws from the mango shells are made by students.

Itzel Paniagua and Alondra Montserrat Lopez say their motivation is their desire to protect the environment and prevent damage to the world's ecosystems caused by plastics.

Mango skin and some types of leaves are finely ground.

For more than a year of research and implementation at the School of Science and Humanities (CCH), they have found a way to blend, research, and deal with leaves.

The end result is a thin, dry sheet of powder that can be rolled into the tube wall and sealed, creating a straw.

Alondra Montserrat Lopez said: 'It's like a normal straw just a little thicker, colored between yellow and brown. It smells like mango but when used with drinks it has no flavor '.

The end result is an oral straw that can be used (pictured) and will decompose naturally in the environment.

'We had to do some investigations and tests; We had a lot of difficulties, but in the end we were successful, ' the UNAM students said. 'And now we want the school to support the project so it can continue to be commercialized.' UNAM, Autonomous University of Mexico, founded in 1910, is a public research university located in the capital, Mexico, Mexico. UNAM is a UNESCO world heritage site.

Plastic waste and straws are a threat to the environment, with their ability to biodegrade in nature, ensuring they exist in nature for hundreds of years. Terrible images show animals struggling to cope with the human waste stream. Turtles and other sea creatures are eating plastic straws and bags after mistaking them for food, dolphins and sharks are dying after being caught in an old fishing net, and birds are making plastic nests .

Change is underway widely to find ways to minimize human impact on the natural world, including alternatives such as biodegradation and seeking to increase recycling efficiency.
