(1/14) So this is going to be my first true long post to Twitter and I am also covering the debate surrounding the banning of plastic straws. As such, I am rather nervous and I can only hope that this turns out alright! #StrawBan
(2/14) I want to focus on an alternative material used in drinking straws. This material is chitosan, which is also sold under the name of “REPA” amongst others. Chitosan is a biodegradable polymer made from renewable materials used to make flexible straws. #StrawBan
(3/14) Firstly, I shall cover the science. Chitosan is a modified form of chitin. Chitin is taken from renewable sources and deacetylated. This typically occurs through treating it with sodium hydroxide in an aqueous solution. #Chemistry #MaterialsScience
