Our research aimed to repurpose non-recyclable wastepaper from Chulalongkorn University Press (CU Press) by incorporating it into the production of molded pulp at E. Molding International Co., Ltd. (EMI). By utilizing this underutilized resource, we assessed the impact on product quality, focusing on parameters such as surface smoothness, strength, and the overall performance of the final molded pulp products. This innovative approach is expected to reduce environmental impact by minimizing waste disposal and the carbon footprint associated with conventional production processes. The results demonstrated that the collaboration between EMI and CU Press establishes a novel model of up-circular economy. This partnership enables EMI to develop more environmentally sustainable products, while CU Press successfully reduces greenhouse gas emissions and progresses toward its Net Zero policy objective.
