“…This approach considers the impacts of the entire construction process, including material selection, transportation, construction activities and waste generation. By evaluating the entire project, LCA can identify opportunities to minimize waste generation and environmental impacts ( Jiang et al, 2023 ; Mesa et al, 2021 ; Stylianou et al, 2023 ).…”

As the demand for materials continues to increase and building lifespans shorten, the construction industry faces mounting pressure to reduce its material and environmental impacts. Mismanagement of construction and demolition waste (CDW) can have severe environmental consequences. To address this, material recovery and circular economy approaches offer significant potential for reducing construction waste through the sustainable use of resources. Existing circular economy and material recovery models that prioritize recycling and reuse efforts demonstrate a sustained commitment to supporting circular practices in the construction and demolition sector. The goal is to minimize waste production, which poses environmental challenges such as raw material shortages and sustainability concerns. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for recruiting relevant literature, this mini review aims to identify the obstacles to implementing circular economy practices in the construction industry, while exploring opportunities for material recovery and circularity. The ultimate aim is to facilitate a fair and smooth transition towards sustainable development, while addressing environmental, social and economic barriers. A more sustainable and circular approach to building construction and management can be attained by considering all the aspects of the CDW cycle, resulting in significant benefits for the environment and society as a whole.

“…Estos residuos se producen durante actividades como la limpieza del terreno, la construcción, remodelación, demolición, así como durante los desastres naturales (Pacheco-Bustos et al, 2017). Como ejemplos, en China se produjeron 2.5 billones de toneladas (t) de residuos de la construcción y demolición (RCD) en el 2020; India produce 750 millones de toneladas anualmente; en la Unión Europea se estimaron 850 millones de toneladas durante el 2022, cantidad equivalente a un tercio de sus residuos sólidos urbanos producidos ese año (Jiang et al, 2023). En Estados Unidos, el 29% de estos se compone por RCD; en Australia, 42% del volumen total equivalen a 9.4 millones de toneladas anuales de RCD.…”

“…La gestión adecuada de RCD por medio de su reaprovechamiento en la industria de la construcción puede favorecer su flujo en un círculo virtuoso en el que los residuos se convierten en un recurso (Véliz et al, 2023). Desde un enfoque sostenible, es importante aprovechar al máximo los materiales recuperados por medio de su reutilización o reciclaje al final de su vida útil (Jiang et al, 2023). Comúnmente, la disposición final de este tipo de residuos incluye desde su vertido clandestino o controlado, hasta su reciclaje en centros especiales o in situ, siendo esta última opción la más económica de todas, con un costo equivalente a 98.31 pesos mexicanos por cada tonelada recuperada (Liu et al, 2019).…”

La insostenibilidad del crecimiento urbano demanda gran cantidad de recursos naturales. Una opción para mitigar este gran consumo es el reúso de residuos de la construcción y demolición en sustitución del cemento y agregados. Se diseñó y construyó un muro verde con concreto ecológico; éste consistió en 10% de concreto triturado en sustitución del cemento y 30% de vidrio en lugar de arena. El relleno de sus macetas contiene suelo vegetal, concreto triturado que sustituyó a las gravas y tabique rojo triturado en lugar de arena. Se determinó que el muro verde ecológico es 7.37% más económico que uno fabricado con materiales naturales. El relleno de las macetas representó 72.08% de ahorro, mientras que el concreto ecológico sólo un 6.1%, dado que el cemento es el material más costoso y se sustituyó únicamente un 10% de la cantidad necesaria. Se concluye que los residuos de la construcción y demolición son una opción económicamente viable para reducir el consumo de recursos naturales como grava y arena a través de alternativas de infraestructura sostenible como los muros verdes.

Concrete waste (CW) recycling stands as a promising strategy to promote sustainable construction practices. This research aims to assess the feasibility of using recycled concrete aggregates (RCA) as a surrogate for natural aggregates (NA) in concrete applications and reduce the environmental impact associated with the depletion of natural resources and landfill space. To achieve these objectives, CW was segregated from debris mixes of construction and demolition waste (CDW), collected, crushed, and graded to generate RCA. Thirty-two concrete samples were prepared and categorized into four distinct groups with 0% (reference), 50%, 75%, and 100% substitution levels for both coarse RCA (CRCA) and fine RCA (FRCA), all utilized simultaneously. Concurrently, the environmental impacts of producing 1 m3 of concrete were evaluated using a life cycle assessment (LCA) approach, (cradle-to-gate) covering three phases, the raw material supply (A1), transportation (A2) and concrete production (A3). At the 50% replacement level, the mechanical properties of recycled aggregate concrete (RAC) demonstrated a 20.0% increase in splitting tensile strength, accompanied by marginal decrease in workability (15.0%) and compressive strength (6.0%). In addition, at that percentage, the average environmental effects were reduced by 31.3%, with specific reductions of 34.7% for A1, 40.3% for A2, and no change in A3.
