Modular life cycle assessment approach: Environmental impact of rainwater harvesting systems in urban water systems.

The environmental assessment of urban water systems through life cycle analysis can be facilitated by using a modular approach. This study aimed to use such an approach to assess the impact of implementing rainwater harvesting systems in buildings in the urban environment during their lifespan, from manufacture to disposal. For this purpose, urban systems were divided into components (water treatment plant, potable water distribution, consumer water use, wastewater collection and wastewater treatment plant).

Life cycle assessment of green roofs: A literature review of layers materials and purposes.

Green roofs offer several environmental and social benefits to urban life. However, such roofs require a greater amount of materials than conventional roofs. The life cycle assessment (LCA) is an appropriate tool that has been used to obtain the potential environmental impacts associated with green roofs throughout their life cycle.

Effect of Ornamental Stone Waste Incorporation on the Rheology, Hydration, Microstructure, and CO Emissions of Ordinary Portland Cement.

The ornamental stone industry generates large amounts of waste thus creating environmental and human health hazards. Thus, pastes with 0-30 wt.% ornamental stone waste (OSW) incorporated into ordinary Portland cement (OPC) were produced and their rheological properties, hydration kinetics, and mechanical properties were evaluated.
