The alternatives were evaluated according to the energy use, the environmental load, the waste generation, the mineral resource ...
Life cycle assessment (LCA) methodology is applied to assess objectively and quantitatively different C&DW management plans during the design phase and to identify the significant environmental aspects. ... They can be treated on site in mobile plants of crushing, concrete plants, gravel–cement plants, soil–cement plants, precast concrete ...
Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and …
Purpose The aim of this literature review is to investigate the role of the beneficiation stage in the Life Cycle Assessment (LCA) of metals and minerals with a focus on the flotation process. Methods The systematic literature search included LCA studies comprising the beneficiation stage in their system boundaries and resulted in 29 studies that met the criteria …
Life Cycle Assessment is an objective process to evaluate the environmental burdens associated with a product, process, or activity by identifying energy and materials used and wastes …
In particular, the life cycle assessment according to ISO 14040 ... The substitutive material that resulted after the crushing process, showed visual differences in the grain form. Anyhow, all m-sand alternatives showed sand …
The use of the ornamental stone wastes, such as the originated from granite or marble, has been the subject of technological studies that evaluated its application in ceramic and cement materials; however, some complementary assessments, such as its life cycle assessment, are still not well explored in the literature. Therefore, the objective of this study …
Through a Life Cycle Assessment study of a rock crusher, Landfield and Karra [3] have shown that the maximum environmental impacts can be attributed to the use phase of the rock crusher. Costic et ...
The end of life phase includes the excavation of the backfill and stone, the creation of the sanitary landfill, the demolition of the wall using a hydraulic breaker for 20 min per m 3 of concrete, the transportation of stone and soil to the sanitary landfill 5 km away and the concrete recycling using a portable crusher with a capacity of 10 m 3 ...
The route that the stone takes through the plant therefore depends on its physical state upon arrival, as well as the product to be produced. The first step of the process is a primary cutting …
This research addresses a critical gap in understanding the environmental impact of natural rock aggregate production in Sri Lanka. The study employs life cycle assessment (LCA) and SimaPro Software to simulate natural coarse aggregates' extraction and manufacture process. Key findings reveal significant environmental impacts, with human carcinogenic …

Nearly 40% of the world's construction industry reported for nearly 40%. Consumption of energy, 30 percent use of raw materials, 25 percent waste, 12 percent of land use and 33% of the world's corresponding GHG emissions [4].According to the latest Indian report, Environmental Change, India's net annual emission of CO2 during 2015 is soared to …
The primary objective of this research is to assess the carbon footprint associated with the production of crushed stone aggregate. Comprehensive data has been systematically gathered from diverse stone quarries and crusher units, encompassing various stages of the …
As the building was claimed to be sustainable on the basis of its outstanding energy-saving performance, an ex post life cycle assessment (LCA) was set up to understand whether, and to what extent ...
Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro LCA software as a case study. ... Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue ...
2. LIFE-CYCLE ASSESSMENT AND EMISSION FACTOR RESULTS The streamlined life-cycle GHG analysis in WARM focuses on the waste generation point, or the moment a material is discarded, as the reference point and only considers upstream GHG emissions when the production of new materials is affected by materials management decisions.2
stone aggregate production through a rigorous Life Cycle Assessment (LCA). By systematically examining each stage of the production process, from quarry operations to the final product, …
Life cycle impact assessment is to characterize the long list of life cycle inventory results into a limited number of environmental impact categories. ReCiPe is one of the most updated impact assessment methods (Huijbregts et al., 2017) and has been applied in many LCA studies (Dong and Ng, 2014). It aggregates the environmental issues at ...

The use of crushed stone aggregate and ...
Followed by the combination of screw crusher and secondary screening system for another three stages of the closed-cycle crushing-screening system. The larger crushed concrete particles from the jaw crusher can be further crushed and sieved with percentages of high-quality aggregates. ... and cement stone. Akbarnezhad (2010) and Akbarnezhad et ...
The life cycle inventory analysis was addressed by following the guidelines specified by the ISO 14044 ().2.1 Functional unit. The unit reference for estimating the inputs and outputs related to the granite production chain was defined as 1 m 2 of finished granite tiles with dimensions of 60 × 40 × 2 cm, which are standard pieces applied in construction.
1.2 Life Cycle Assessment Life Cycle Assessment is an objective process to evaluate the environmental burdens associated with a product, process, or activity by identifying energy and materials used and wastes released to the environment, and to evaluate and implement opportunities to affect environmental improvements.
