Abstract
In Reunion Island, agricultural waste from pineapple cultivation and Furcraea Foetida (a pestilence alsoknown as choka) are not currently valorized. In the construction sector, non-biosourced thermal insulation has asignificant environmental impact, despite being essential for reducing the energy consumption of buildings. In this study, we are interested in the valorization of these waste products through fibers extraction for the production of loose-fill thermal insulation. The objectives are (i) to characterize choka leaf fibers, (ii) to evaluate the thermal conductivity of an insulator produced from choka fibers and (iii) to evaluate the thermal conductivity of a loose-fill insulator produced frompineapple leaf mash as a function of density. The minimum thermal conductivities obtained are 0.066 W/m.K for choka fiber insulation (density 0.022) and 0.058 W/m.K for pineapple leaf mash insulation (density 0.159).
