We’ve been hearing a lot about eco-friendly biodegradable plastics made from nanocellulose. Although those fibers are usually obtained from wood chips, according to a study by Japanese scientists, we can get that fiber from coffee grounds. And the best news is that the supply of this material is very abundant.
There is currently no accurate statistics on the supply of coffee grounds. But according to the International Coffee Organization estimates, more than 6 million tons of coffee grounds are discarded in the world every year. Some of the residue is composted as fertilizer while others are used in carbon capture materials, biofuels or road building materials. Those are just a few though, and most coffee grounds are often wasted.
This waste makes many scientists question, including scientist and professor Izuru Kawamura at Yokohama National University, Japan. He decided to study whether this “junk” of coffee could be used as a source of cellulose nanofibers. As a result, coffee grounds show great potential for capturing cellulose nanofibers. Specifically, about half their weight and mass can be used to make cellulose nanofibers .
The researchers used a process called catalytic oxidation, in which a catalyst is used to oxidize the cell walls in ground beans.
More than 6 million tons of coffee grounds are dumped in the world every year.
After obtaining the cellulose nanofibers in the coffee grounds, the scientists continued to analyze and found a homogeneous structure. These fibers fuse very well with polyvinyl alcohol (CH2CHOH) , a water-soluble synthetic polymer obtained by polymerization of vinyl alcohol. This polymer is commonly used in the production of biodegradable plastics.
From there, the team came up with the idea of using coffee grounds to make biodegradable plastic.
“Now more and more restaurants and cafes have banned single-use straws. And following that movement, we aim to create a transparent coffee cup and straw,” Kawamura said. is made from a number of additives including cellulose nanofibers made from used coffee grounds”.
