Sustitución Sostenible del Tablero de MDF-Melamina en Mesas Binarias Desechadas en Instituciones de Educación Superior
Summary
This study demonstrates a laboratory-scale process for manufacturing boards from recycled high-density polyethylene (HDPE) as a sustainable replacement for deteriorated MDF-melamine panels in university furniture. Using 5.6 kg of HDPE waste to produce 16 boards via compression molding, the approach shows recycled plastics can serve as a practical, lower-emission alternative to conventional composite wood products.
The improper management of plastic waste is a global problem due to its slow degradation, which pollutes the ecosystem. Recycling high-density polyethylene (HDPE) is a sustainable solution that reduces carbon emissions compared to the production of new plastic, benefiting both the environment and the economy. This study focuses on the laboratory-scale production of HDPE boards to replace deteriorated MDF-Melamine boards in the División Académica de Ciencias Biológicas (DACBiol) at the Universidad Juárez Autónoma de Tabasco (UJAT). The compression molding process includes eight steps: collection, washing, grinding, melting, molding, pressing, demolding, and finishing. A total of 5.6 kg of HDPE was used to manufacture 16 boards measuring 17x17x1.2 cm, with epoxy resin optionally used for the final finish. The results demonstrate that recycled HDPE is a viable alternative for reducing plastic waste and pollution, offering a practical solution for public and private institutions.
