Thermal properties play a critical role in the compost used as a soil amendment for different agricultural applications especially for green roof buildings. Despite this importance, there remains insufficient information on thermal conductivity of composted olive cake (COC), K, and how it is influenced by bulk its density and water content. This shows how thermal conductivity (K) is affected by these two parameters and the potential use of COC as cheap padding in geothermal heat storage and green roof building applications. Thermal conductivities of 30 samples of (COC) were measured experimentally at different moisture contents and bulk densities using a hot wire technique. The results revealed that thermal conductivity exhibits a linear increase as both bulk density and water content increased. It increased from 0.10 to 0.60 W/(m K) at saturation levels ranging from dry to 90 %. The highest thermal conductivity of 0.60 W/m K was revealed at a water content of 90 %. Therefore, (COC) might be used as an inexpensive padding in geothermal heat storage applications and as an eco-friendly insulation pad in green- roof buildings, leading to passive energy savings. Overall, the study provides important insights into the thermal properties of COC and its potential as a sustainable insulation material.
热性能在用作不同农业应用（特别是绿色屋顶建筑）土壤改良剂的堆肥中起着关键作用。尽管具有这种重要性，但关于堆肥橄榄饼（COC）的热导率、K以及它如何受到堆积密度和含水量影响的信息仍然不足。这表明了热导率（K）如何受到这两个参数的影响，以及COC在地热蓄热和绿色屋顶建筑应用中作为廉价填充物的潜在用途。使用热线技术在不同含水量和堆积密度下对30个堆肥橄榄饼（COC）样品的热导率进行了实验测量。结果表明，随着堆积密度和含水量的增加，热导率呈线性增加。在从干燥到90%的饱和度水平下，热导率从0.10瓦/（米·开尔文）增加到0.60瓦/（米·开尔文）。在含水量为90%时，热导率最高，为0.60瓦/米·开尔文。因此，COC可在地热蓄热应用中用作廉价填充物，并在绿色屋顶建筑中用作环保隔热垫，从而实现被动节能。总体而言，该研究为COC的热性能及其作为可持续隔热材料的潜力提供了重要见解。
