    Development of a new insulation material from hazelnut shells (hazelnut shell insulation board - HSIB)
    (Polish Society Magnesium Research, 2023) Ozocak, Murat; Sisman, Can Burak
    Environmental pollution caused by waste is constantly increasing. In this context, waste disposal efforts have gained importance. Among possible solutions, the disposal of waste by converting it into a new product stands out. In addition to preventing environmental pollution, it is also possible to obtain a new product by utilizing wastes, especially generated by agricultural production. A new insulation material (HSIB) has been developed from hazelnut shells used in different proportions. The aim of this study has been to produce insulation boards by using the shells released as waste after hazelnut production. For this purpose, 5 mm thick insulation boards were made by gluing very fine-grained (0-4 mm) hazelnut shells with epoxy and pressing. Two separate types of board were formed, composed of 80% and 90% of the hazelnut shells and 20% and 10% epoxy as binder, respectively. Thermal conductivity, sound transmission, water absorption, unit volume and compressive strength tests were carried out on both board types. The results showed that the unit volume weights of the boards were 1.543-1,592 g cm - 3 , thermal conductivity coefficients were 0.136-0.148 W(m.K) -1 , and sound transmission velocities were 1196-1270 m s -1 . Thermal conductivity and sound transmission values have a strong linear correlation with volume. Within the scope of the research, it can be said that the insulation board (HSIB) developed by using hazelnut shells, which are agricultural waste, can be used to improve thermal insulation in different parts of buildings, such as walls and ceilings.
