Variability in the porosity of natural rocks and waste have been investigated in relation to the influence on the
permeability of gases and water. The samples were of sedimentary or igneous rocks, carbon-rich rocks, and solid
porous waste material after thermal conversion. Using mercury intrusion porosimetry, porosity values and pore
size distribution varied with the origin of materials. These results have been compared and a connection between
the origin and porosity of material was observed. Total porosity values of selected samples ranged from ca. 0.2%
for granite to 55% for waste porous material. Lower porosity values demonstrate the connectivity between
mesopores or micropores and are related to the capturing of greenhouse gases, while higher porosity is caused
predominantly by the presence of macropores and coarse pores, which serve as pathways for permeability of
gases and liquids.
