The concept of energy efficiency has gained importance worldwide due to decreasing energy resources and the increasing need for energy. Significant energy savings can be achieved in building heating and cooling via insulation applications. Biocomposite materials constitute the majority of research on developing new composite materials. Hemp-based biocomposites are still new, they are attracting attention because of their natural and light properties, economical advantages, and thermal performances. Although the thermal properties of this material have been more thoroughly investigated, its mechanical properties have been examined to a lesser extent. In this study, the effect of the properties of hemp shives obtained from different regions of the stem part of the male and female hemp plants on the compressive strength of hemp-based biocomposites was investigated. Hemp-based biocomposites were produced with the 0–0.5, 0.5–1, and 1–3 cm sized hemp shives from different stem regions and mixing them with lime, fly ash and slag based binder material. It was observed that the gender and the stem region of the hemp plant as well as the size of the hemp shives affect the compressive strength of biocomposites. It was determined that the compressive strength value of biocomposites containing female hemp shives in all mixtures was higher than that of biocomposites containing male hemp shives. Additionally, the medium sized (0.5–1) shives provided higher strength. In case of biocomposites production with large-sized shives, it is recommended to use shives obtained from the upper parts of hemp to obtain higher compressive strength.
