This work is focused on the upgrading olive oil pomace to obtain high environmentally friendly insulationmaterials for the construction and building industry. Upgrading of these wastes has been carried out by using the wet-laidtechnology in combination with different thermoplastic binder fibers both from natural and synthetic origin. After the wetlaidprocess, the obtained veils or non-wovens were subjected to different processes: a hot-press moulding process or acontinuous lamination process. The acoustic insulation properties were obtained by the Kundt’s tube while the thermalinsulating properties were obtained through determining heat transmission resistance (R) and heat absorption parameter (λ). These tests have revealed the excellent insulation properties of the olive pomace-derived materials, specifically, those basedon high surface density non-wovens. The complementary process that follows wet-laid, i.e. hot-press moulding orcontinuous lamination process has a remarkable effect on insulation behaviour. In particular, the hot-pressed materials fromolive pomace show better acoustic insulation while the continuously laminated materials offer the best thermal insulationproperties.
