This study investigates the thermal and acoustic insulation properties of composite panels produced from recycled waste paper fibers through a low-energy, binder-assisted compression molding process. Panels are fabricated using shredded office paper and newspaper as primary feedstock, combined with minimal amounts of natural starch binder and fire-retardant additives. Thermal conductivity is measured using the guarded hot plate method, yielding values between 0.038 and 0.045 W/m·K—comparable to commercial mineral wool and superior to expanded polystyrene in moisture-rich environments. Acoustic absorption coefficients, determined via impedance tube testing, range from 0.6 to 0.9 across the 500–4000 Hz speech frequency band, with peak performance at mid-frequencies due to porous fiber entanglement and air cavity resonance. The panels exhibit low density (120–180 kg/m³), high recyclability, and compliance with building fire safety standards when properly treated. These findings establish waste paper insulation as a sustainable, high-performance alternative for energy-efficient and acoustically comfortable buildings.
