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.

The decay heat of fission products plays an important role in predictions of the heat released by nuclear fuel in reactors. In this contribution we present results of the analysis of the measurement of the beta decay of some refractory isotopes that were considered possible important contributors to the decay heat in reactors. The measurements presented here were performed at the IGISOL facility of the University of Jyvakyla Finland. In our measurements we have combined for the first time a Penning trap (JYFLTRAP), which was used as a high resolution isobaric separator, with a total absorption spectrometer. The results of the measurements as well as their consequences for decay heat summation calculations are discussed.
