“…Además, se ha evidenciado la necesidad de gestionar desperdicios a partir de contemplar políticas, tales como: caracterización e infraestructura de desperdicios y reutilización de materiales, donde se destaca la economía circular (Rondón et al, 2022). Una vez detectados los faltantes e indefiniciones del proyecto, se realizó una evaluación de la información disponible en el proyecto ejecutivo para determinar la conveniencia de seguir o no con la ejecución del proyecto, así como decidir si seguir con el plan de método "Fast Track" o implementar una metodología de gestión diferente.…”

Within lean manufacturing applications, its contextualization in construction processes is found as lean construction. This approach aims to reduce non-value-adding activities by optimizing processes to maximize efficiency. Thus, the objective of this research was to propose a procedure for adopting the lean construction methodology to contribute to the optimization of building projects. A mixed-method study was conducted with a cross-sectional, descriptive focus based on the case study: construction of a recreational theme park for terminally ill children. A procedure structured in six steps was designed, allowing the adoption of the lean philosophy in project management and the design of a tool to assess the project team's competencies in integrated management systems. The results enabled the definition, design, and delivery of project assets with the highest possible value generation, where lean methodology principles were applied. Likewise, the integrated project systems, stemming from incorporating lean methodology principles, optimized project productivity in building construction.

Municipal solid waste (MSW) management in Spain, particularly in the Valencian Community, heavily relies on mechanical–biological treatment (MBT) plants followed by landfill disposal. These MBT facilities utilize mechanical processes like shredding, screening, and sorting to segregate recyclables (metals, plastics, paper) from organic material and other nonrecyclables. While public funding supports these plants, private entities manage them through complex, long-term concession contracts. This structure restricts access to crucial data on the sale prices of the byproducts generated during MBT. Publicly available information on relevant company and administration websites is typically absent, hindering transparency surrounding byproduct revenue. This study addresses this gap by analyzing 2012’s available data on revenues obtained from byproduct sales following mechanical treatment at MBT plants within the Valencian Community and comparing them with Spanish national data. This research revealed a significant finding—the statistical distribution of average prices obtained from Ecoembes auctions in the Valencian Community mirrored the corresponding distribution for prices calculated from auctions conducted in other Spanish regions. This suggests a potential uniformity in byproduct pricing across the country. It has also been found that none of the analyzed price distributions exhibited a normal (Gaussian) distribution. The findings also highlight the need for alternative pricing models that move beyond simple averages and account for regional variations and outliers. As actual prices are not available after 2012, this lack of transparency poses a challenge in comprehensively evaluating the economic viability of MBT plants. Furthermore, it raises concerns regarding whether the revenue generated from byproduct sales reflects fair market value. Limited public access to this information can potentially indicate conflicts of interest or inefficiencies within the waste management system.
