Sustainable Masonry Made from Recycled Aggregates: LCA Case Study

For a sustainable building industry, reusable construction with a low demand for primary resources is needed. Moreover, if we want to reduce the amount of construction and demolition waste, construction with recycled aggregate should be considered. To investigate the environmental impacts of such concrete construction, life cycle assessment (LCA) was used to compare the following types of concrete construction: Reusable blocks with recycled brick aggregate, reusable blocks with recycled concrete, reusable blocks with natural aggregate, and regular concrete wall. Firstly, the properties of new concrete with recycled aggregate were measured, such as physical, mechanical, and thermal properties. Then, different constructions were designed and assessed using the method of Institute of Environmental Sciences (CML2001) and the method of National Institute for Public Health and the Environment (ReCiPe 2016) as characterization methods. Unsurprisingly, the regular concrete wall had a higher impact on most of the impact categories, e.g., 113 kg CO 2 eq. (in the first scenario, using CML2001). In accordance with the circular principles, the reusability of blocks and recycling of aggregate are the main factors that affect the environmental impact of the constructions. Thus, the global warming potential (GWP) of construction with reusable recycled concrete blocks was only 53 kg CO 2 eq. (in the second scenario). Moreover, we show differences in the results of CML2001 and ReCiPe 2016, e.g., in the Photochemical Oxidant Creation category.

“…Within the LCA framework this is done by defining a "functional unit". In previous LCAs of the built environment in Malaysia the functional unit chosen has been per metre squared of habitable space (Jia Wen et al, 2015;Abd Rashid et al, 2017). This unit allows fair comparison between the significant difference in size of the buildings, expressing the environmental impact and energy consumption per metre squared.…”

The production of Portland cement is well acknowledged as having a significant impact on the environment, accounting for 8% of global CO2 emissions (4bn tonnes per annum). Concrete is the most widely used man-made material in the world and therefore has a vast potential to absorb high volumes of waste and by-product materials. These materials can act as partial replacements, i.e. supplementary cementitious materials, or total replacements and be the cement-like precursors for geopolymer concretes. The LowCoPreCon project brings together academic and industrial partners from the UK and Malaysia with the aim of identifying available waste streams with which to manufacture geopolymer concretes on a commercial scale. Initial laboratory work was conducted by academic partners to design geopolymer concretes that had both optimum strength and workability. These mixes were then used in factory trials to successfully cast structural elements, including building blocks, wall slabs and staircases. To determine the potential environmental benefits of geopolymer concrete, a detailed life cycle assessment will be conducted. Two demonstration projects using the novel material will be constructed in Malaysia; a domestic building and a FlexiArch bridge.

“…By considering impacts throughout the life cycle of a product, life cycle assessment (LCA) provides a comprehensive view of the environmental aspects of a product or process and a highly accurate picture of environmental trade-offs in product and process selection ( Khasreen, Banfill & Menzies, 2009 ). This method has been proven to be useful and has been widely applied in studies on the environment and waste management ( Abd Rashid et al, 2017 ; Finkbeiner et al, 2010 ; Ozkan et al, 2016 ; Rigamonti, Grosso & Giugliano, 2010 ; Singh et al, 2011 ). Several studies on LABs have focused on environmental performance and impacts from the perspective of product life cycle ( Abd Rashid et al, 2017 ; Finkbeiner et al, 2010 ; Ozkan et al, 2016 ; Rigamonti, Grosso & Giugliano, 2010 ; Singh et al, 2011 ).…”

BackgroundChina has the largest lead–acid battery (LAB) industry and market around the world, and this situation causes unavoidable emissions of Pb and other pollutants.MethodsOn the basis of a field survey on a starting–lighting–ignition (SLI) LAB plant in Zhejiang Province, this study applies life cycle assessment (LCA) and life cycle costing (LCC) methods to assess the environmental impacts and environment-related costs derived from the LAB industry during the life phases, including material preparation, battery assembly, transportation, and regeneration of the plant.ResultsMaterial preparation and regeneration phases contribute 3.4 and 42.2 g to Pb emission, respectively, and result in 3.29 × 108 CHY of environmental cost for each function unit (1 KVA h LAB capacity). The material preparation phase is the largest mass contributor to global warming potential (GWP, 97%), photo-chemical oxidation potential (POCP, 88.9%), and eutrophication potential (EP, 82.5%) and produces 2.68 × 108 CHY of environmental cost.DiscussionDecision makers in the Chinese LAB industry should replace the pyrogenic process in smelting with the use of clean energy, increase the lead recovery rate while producing the same capacity of LABs, and develop new technologies to reduce heavy metal emission, especially in the regeneration phase.
