Biodegradable bunch covers

Wednesday, 25 January 2017

Chemistry students at the University of Costa Rica developed biodegradable bunch covers, for which they won a prize at the Feria de Emprendimiento Desarrollo e Innovación. The main components are plant cellulose, cassava starch and chitin extracted from shrimp shells. The covers are five times more resistant than the conventional ones and are equipped with a system to gradually release pesticides. They take 18 months to disintegrate.
