Innovative particleboard material from the organic fraction of municipal solid waste

This study presents a challenging approach that addresses the efficient management of organic fraction municipal solid waste (OFMSW) by hydrothermal carbonization (HTC) for development novel sustainable low-CO 2 building materials. Mild HTC treatment at 180 °C h transformed low-grade OFMSW into renewable carbonaceous (hydrochar), which displays promising properties application in particleboards. Taking advantage presence extractives acting as natural binders, hydrochar particles with sizes <0.3 mm, 0.3–1 and 1–2 mm agglomerate successfully simple pressing 3 MPa 7 min room temperature (? 25 °C). The resulting binderless monolithic probes display density 838 883 kg/m finest coarsest grain sizes, respectively, approximately 30% porosity. mechanical resistance is enhanced use larger particle values modulus rupture tensile strength 21.64 18.99 are reached, respectively. thermal conductivity range 0.091–0.132 W/(m?K) suggests potential OFMSW-derived insulation panels. • Food precursor material.
