The papers were subjected to five disintegration durations at four temperatures, thus yielding 20 experimental groups. The analysis encompasses pivotal parameters such as basis weight, surface smoothness, and brightness. The findings indicate that a 30-minute disintegration time at 40 degrees Celsius provides optimal conditions, yielding high brightness (L*=90.43), low air permeability (6.11 µm/min), and uniform surface properties (3,887 µl/min). The commencement of a 60-minute disintegration period resulted in a decline in optical quality, brightness (L*=87.54), and gloss (33%). It has been demonstrated that an increase in temperature of up to 40 degrees Celsius has a beneficial effect on fibre distribution. It was demonstrated that at 60 degrees Celsius, there was a negative impact on surface characteristics. The study hypothesises that 30–40 minutes of disintegration at 40 degrees Celsius is optimal for the production of recycled paper. The efficacy of these parameters in enhancing energy and resource efficiency in recycling processes has been demonstrated. Further exploration is recommended, with different fibre blends and chemical additives to enhance material performance.}, publisher={Gazi Üniversitesi}
