ABSTRACT
A manually operated paper-recycling machine was designed and fabricated. This was done to enable waste paper conversion into useful product. The fabricated plant consists of six major component units that include the disc refiner, the hydropulper, the head box, the felt conveyor, the driers and the rollers. From the results of experimental analysis carried out on the study, it was discovered that for every 0.1kg of used paper fed into the refiner, about 7000ml of water is required to defibre it, and about 0.2 kg of starch adhesive is required. The calculated volume of the refiner, hydropulper and head box is 11795.62cm3, 62930.47cm3 and 60979.096cm3 respectively. The fabricated machine is capable of producing 7.6 kg of recycled paper from 10 kg of used paper.
