Abstract

The accumulation of plastic and industrial waste presents significant environmental challenges. This study explores the upcycling of polypropylene (PP) and polyethylene terephthalate (PET) from local plastic waste sources, along with ceramic waste (CW) and gypsum plaster waste (GPW) from the ceramic industry, into alternative construction materials. Fifty-two formulations were developed and evaluated for their physical and mechanical properties. Formulations with 90 % industrial waste achieved compressive strengths of 15–20 MPa, bulk densities of 1.4–1.7 g/cm³, and water absorption rates of 3–6 %, demonstrating structural viability. Acid resistance tests indicated minimal weight loss, confirming chemical durability. Regression analysis revealed a strong correlation between compressive strength and bulk density (R² = 0.57 for PET composites). A cost analysis estimated production costs at 619–633 THB per square meter, indicating economic feasibility. These results demonstrate the feasibility of repurposing ceramic and plastic waste into durable, low-cost construction materials, demonstrating material efficiency and potential for waste utilization.

将陶瓷工业和当地塑料废物升级为可替代的建筑材料，重点是性能和材料利用

塑料和工业废物的积累对环境构成了重大挑战。本研究探讨了从当地塑料废物来源中升级回收聚丙烯（PP）和聚对苯二甲酸乙二醇酯（PET），以及陶瓷工业的陶瓷废物（CW）和石膏废物（GPW），作为替代建筑材料。开发了52种配方并对其物理和机械性能进行了评估。含有90%工业废料的配方抗压强度为15-20 MPa，容重为1.4-1.7 g/cm3，吸水率为3-6%，具有良好的结构可行性。耐酸测试表明，重量损失最小，证实了化学耐久性。回归分析显示，抗压强度和体积密度之间存在很强的相关性（R2 = 0.57）。成本分析估计生产成本为每平方米619-633泰铢，表明经济可行性。这些结果证明了将陶瓷和塑料废物转化为耐用、低成本建筑材料的可行性，展示了材料效率和废物利用的潜力。

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
