On the market, there are many bioplastics made from plant material instead of petroleum. Most of them are made by extracting starch from corn and converting it into a plastic known as polylactic acid.<\/p>\n\n\n\n
Lately, researchers have been working on making plastics and chemicals from Cellulose, the main component that can be extracted from waste paper. One group made a transparent plastic from starch and Cellulose. In contrast, another group has reported a cellulose-based foam that is a better packing and insulation material than commonly used Styrofoam.<\/p>\n\n\n\n
Engineers at Yokohama National University<\/a> have used coffee grounds as a source for making Cellulose. Around ten percent of the dry weight of fields consists of Cellulose, they write in their research published in the journal\u00a0Cellulose<\/a>.<\/p>\n\n\n\n To extract the Cellulose from spent coffee grounds, the team used a catalyst that oxidizes and fragment the coffee beans\u2019 cell walls. <\/p>\n\n\n\n The resulting microscopic cellulose fibers were uniform in their structure. And they could easily be mixed in polyvinyl alcohol\u2014a polymer used to produce biodegradable plastics\u2014to make a composite plastic.<\/p>\n\n\n\n The results suggested that spent coffee grounds are a practical substitute for wood to make cellulose nanofibers. They could be used to make plastic composites for many products.<\/p>\n","protected":false},"excerpt":{"rendered":" Engineers at Yokohama National University have used coffee grounds as a source for making Cellulose.
