In search of sustainable improvement in the construction field, this investigation explores innovative alternatives that promote more environmentally friendly and economically viable practices. The study focuses on the evaluation of plastic wood as a potentially sustainable construction material, compared to traditional natural wood. Standardized and experimental tests, including shear, bending, compression, fire resistance, and wear tests, were conducted to evaluate the mechanical behavior and durability of both materials. The experimental methodology incorporated the exposure of samples to simulate environmental stressors, such as immersion in fresh and saltwater, burial, and outdoor exposure. This approach allowed for an assessment of the materials' responses to different environmental scenarios, providing valuable data on their performance in real-use conditions. This study focuses on the analysis of the environmental impact and sustainability of both materials. To achieve this objective, the Leopold Matrix method was used. Plastic wood, manufactured from plastic waste, represents a prime example of a circular economy, significantly contributing to waste reduction and resource reuse. In contrast, the sustainability of natural wood is critically examined, considering the negative effects of deforestation and unsustainable logging practices. The research aims to provide information to motivate the adoption of more sustainable materials and techniques, showing practical applications where the use of each type of wood is intended to be simulated.
Mass movements detection from UAV images analysus

Biophysical conditions, the lack of governance and the weak applications of planning and territorial planning policies are aggravating factors of affections caused by natural disasters in Latin America. In Ecuador, landslides have caused not only material but also human losses, which shows the lack of immediate actions to avoid human settlements in risk areas or more controlled evacuations protocols, in case of early detection of risk areas due to this type of events. This article is part of an applied research project for the City of Cuenca allowing to take advantage of the information provided by citizens with a PPGIS. Furthermore, remote sensor images are analyzed, in order to identify in a semi-automated way, risk areas due to mass movements problems. Two approaches for semi-automated detecting areas where mass movements happen have been explored, i) Temporal images obtained by a LiDAR; and ii) Temporary images obtained by flights of an unmanned aerial vehicle, UAV. This paper present the procedure followed by comparison of image outcomes. The resulting analysis clearly presents the applicability of the two techniques thus allowing the determination of maps and early detection of landslides.
