Abstract

The need for renewable and sustainable resources is increasing like an avalanche every day in order to take measures against the decreasing oil resources on earth and the crises that will be experienced in the related industries. Lignin, a natural biopolymer, is abundant in terms of renewable resources. Nowadays, very intensive efforts are being made to evaluate the wastes of biological resources and to produce upcycled materials. In this study, we synthesised polyurethane by polycondensation reaction by obtaining lignin from corn cob wastes and chitosan from shrimp shells. The effects of temperature, pressure and time on the synthesis process were investigated and the optimum process conditions were determined. It was concluded that the production efficiency increased with the effect of catalyst and the water output rate improved accordingly. It is stated that the adhesion process of polyurethane with metal cans is compatible with the adhesion process of polyurethane to be used in the filter sector.
