This study aimed to experimentally acquire evolution profiles between depth, bulk density, Free AirSpace (FAS), air permeability and thermal conductivity in initial composting materials. The impact oftwo different moisture content, two particle size and two types of bulking agent on these four parameterswas also evaluated. Bulk density and thermal conductivity both increased with depth while FAS and airpermeability both decreased with it. Moreover, depth and moisture content had a significant impact onalmost all the four physical parameters contrary to particle size and the type of bulking agent.
