Description

<p>Paper has an established recycling method, as its raw material, the wood, used to make pulp, takes about 10 years to grow. Its product life, however, is short. The process of removing the plastic coating of water-resistant paper during re-extraction of pulp while recycling is inefficient. Therefore, in this study, a fabrication method was devised to directly pulverize water-resistant paper and utilize it as a filler for plastic. The “crushability of water-resistant paper” and “compatibility of filler and resin” are important factors for using pulp as filler. Hence, we also evaluated the shape of pulp and conducted tensile tests on composite materials using the pulp. Results showed that pulp is less likely to form agglomerates and exhibited optimal tensile properties when subjected to the absolute, dry, blade-impact milling method.</p>
