“…Solís-Guzmán et al, (2009) desarrollan un modelo de éxito implementado en la Comunidad Alcores (Sevilla) en España donde se calcula los volúmenes totales y subgrupos de los residuos: demolido, restos y desechos de empaque, mediante una clasificación sistémica de los materiales utilizados y cálculo de desechos esperados. Además, se observa en la literatura diversas metodologías de cuantificación, a saber: Inspección en Obra; Cálculo de tasa de generación; Análisis de Ciclo de Vida; Clasificación por Sistemas de Acumulación; Modelamiento Variable; entre otras, cuya elección dependerá de los recursos y nivel de detalle que se desee en la investigación (Wu et al, 2014y Subramaniam et al, 2018. Por otro lado, en un estudio preliminar de residuos de la construcción en Antofagasta (Chile) se calculó que en edificación habitacional en altura por cada m 2 construido se generan 0,220 m 3 de residuos (Cámara Chilena de la Construcción, 2013).…”

Este artículo presenta un estudio de evaluación económica y clasificación de residuos de construcción y demolición (RCD) en un proyecto real ubicado en la Región Metropolitana, Chile. Chile genera más de cinco millones y medio de toneladas de RC&D al año y afectan de múltiples maneras el medio ambiente. A su vez, los RC&D son un síntoma de problemas de productividad. Una adecuada gestión de los residuos requiere una cuantificación de los mismos. Sin embargo, se observa una carencia en la literatura relacionada a la cuantificación de los volúmenes de residuos y su impacto económico (generación, transporte y disposición final). Se encuentra que el volumen de residuos generados por superficie construida para este caso de estudio es de 0,186 m 3 /m 2 de RCD con un costo total de 188.234,44 US$ correspondiente al 1,19% del presupuesto. Así mismo, el costo ponderado de la gestión del RCD se estimó en 75,47 US$/m 3 .

“…Moreover, the approximate waste generated rate from Malaysia residential project was determined by calculating the total GFA of the project (7,895,147.461 m 2 ) as adopted by numerous researchers [107][108][109]. This can be calculated as Equation (3).…”

Modeling of 3R (Reduce, Reuse and Recycle) for Sustainable Construction Waste Reduction: A Partial Least Squares Structural Equation Modeling (PLS-SEM)

et al. 2021

There is a lack of awareness and knowledge among the Malaysian construction industry about waste management reduction. Numerous nations worldwide have understood and have incorporated the concept of the 3R (reduce, reuse, and recycle) in waste management, and it has worked out well. This study investigated construction waste issues and developed a model for sustainable reduction by applying 3R using a partial least squares structural equation modeling PLS-SEM in Malaysia. The research methodology adopted the quantitative and qualitative approaches by sending a survey questionnaire to the relevant stakeholders to obtain their views or perceptions and interviewing an expert in the related field about waste reduction in the Malaysian construction industry. Three hundred thirty questionnaires were collected within six months of submission. The significant factors are determined using mean ranking for the reduce, reuse and recycle elements. Based on the results, the exploratory power of the study model is considered sustainable with R2 values of 0.83%. At the same time, the results of relationships between improving factors, policy-related factors, construction waste generated, and sustainable construction waste reduction were significant. Also, the findings revealed that the top factors for waste generation on reducing, reusing, and recycling are lack of design and documentation, and lack of guidance for effective construction waste-collecting. The paper will explore different and dynamic practices, such as recycling, reuse of construction waste management cost reduction, enabling stakeholders and managers to estimate and quantify the actual size of CWM costs and benefits for sustainable development goals.

The service industry sector is one of the livelihoods in Indonesia. This sector has increased from year to year. This study aims to identify and determine the amount of dominant waste in consulting service companies based on the concept of lean service and provide recommendations to minimize the occurrence of dominant waste from the causal factors. The results of the identification of waste using the value stream mapping show that there are activities that are non-value-added with a total time of 200.52 minutes of a total time of 839.01 minutes or 23.90% in the process of public training services. Based on the future state from value stream mapping after processed improvements there was founded that the time of activities that non-value-added reduced by 136.36 minutes, from 839.01 minutes to 702.65 minutes or reduced by 16.25%. The proposed improvements provided based on the analysis of critical waste causes to minimize waste dominant in the form of waste waiting are the addition of new employees for marketing, making Standard Operating Procedure, setting training price standards, and increasing bandwidth to increase internet speed in the work environment.
