Diseño de aislación termoacústica con bioplásticos cítricos en estación intermodal

Abstract

This research addresses environmental pollution related to construction and the lack of effective thermoacoustic insulation in high-traffic urban spaces, using the La Cisterna Intermodal Station in Santiago de Chile as a case study. It develops and validates a bio-based composite material made from orange peels and natural binders as a sustainable alternative to expanded polystyrene (EPS). The methodology focuses on experimental formulation, specimen fabrication, standardized physical, thermal, and acoustic tests, and the design of a modular prototype for platform application. Results demonstrate insulation properties comparable to or exceeding those of EPS, with added benefits in biodegradability, cost-efficiency, and productive viability using agro-industrial waste. These findings support the proposal of this material as a viable solution for small and medium-sized enterprises, fostering environmental linkage and enabling its presentation as a public policy initiative eligible for sustainability and entrepreneurship funding. Originating from a master’s research project, this work contributes technically and environmentally to the construction sector, aligning with Sustainable Development Goals 9, 12, and 13.
