“…There is no LCIA study of mineral processing industries that consider national emission inventories, which are publicly available emission databases. The national pollutant inventories have been shown to provide a source of data that can be used to estimate environmental impacts of power generation technologies 21 . This work presents for the first time LCIA study of environmental and economic impact assessment of Australian metal production industries using the emission data of the Australian national pollutant inventory to determine the relative performance of different industries, as well as reveal the areas which require further improvement and control by the industrial processes in order to reduce their emissions and environmental impacts while still contributing to the national economic development.…”

Metal production industries are associated with positive economic benefits, however their activities are significantly resource and energy intensive, contributing to emission of pollutants and greenhouse gases to the environment. The balance between the economic inputs and environmental footprint of the metal production industries determines their contribution to sustainability. This work provides environmental impact assessment of the production of aluminium, copper, gold, iron and steel, lead, nickel and zinc, and considers their contribution to the economy. The emissions of selected representative industries in Australia were sourced from public national emission inventories and used as input parameters in the openLCA software. ReCiPe midpoint and endpoint hierarchist impact assessment methods were used to investigate the environmental impacts of the selected industries. The results indicate that lead, followed by aluminium and nickel production had the largest environmental impacts. The work further revealed the specific emissions for better control for each industry taking into consideration their relative environmental and economic impacts. For instance, adoption of renewable energy sources would significantly decrease the greenhouse gas emissions and the associated environmental impacts of the copper, zinc, gold, and iron and steel production industries. Improvement of sustainability of the production of lead would require further control of trace metal emissions, while for aluminium and nickel production, improved control of emissions of particles and the acidic gases SO2 and NOx.

“…Previous studies have shown that the effect of mixed combustion of biomass fuel and fossil fuel is better than that of combustion alone (Khorshidi et al, 2013). Strezov and Cho (2020) used ReCiPe2016 as an impact evaluation method to assess the environmental J o u r n a l P r e -p r o o f impact of direct emissions from combustion-based electricity generation systems fueled by hard coal, lignite, diesel, natural gas, coalbed methane, sewage gas, landfill gas and bagasse on air, water and soil in Australia. This study claimed that lignite, anthracite and diesel had more serious impacts on human health and ecosystems, while renewable fuels such as bagasse, landfill gas and sewage gas showed relatively small impacts on human health and ecosystems (Fig.…”

“…The energy policy focuses on developing renewable energy sources, reducing dependence on fossil fuels, and reducing energy consumption. So, the landfill is considered a renewable energy source as it has the potential to be an important source of human methane emissions, it is also a viable source of landfill gas (LFG), which can be used to produce heat and electricity [2,3]. There are two main types of landfills design namely traditional and bioreactor.…”

Landfills are a cheap alternative to municipal solid waste (MSW) disposal at present in upper Egypt where the desert is spread. It is worth mentioning that, After the treatment process, around 20% of MSW will be disposed of in landfills. This paper aims to compare the different types of landfills design, namely traditional and Bioreactor, investigating the amount of gas collected, the period of gas generation, the potential life cycle cost of the landfill, and the usage of landfill area after closure. The data relating to the MSW such as waste generation, waste characterization, and collection efficiency were measured in four Egyptian governorates named Luxor, Aswan, Minya, and Suhag which are in upper Egypt. A commercial software named Land GEM was used to calculate the amount of generated landfill gases (LFG) from each landfill design for each governorate. Furthermore, a mathematical model is established to calculate the power generated from the gas produced in each design. It will be noted that the generation of LFG is the highest for bioreactor design compared to traditional design according to the high level of waste decomposition which leads to a decrease in the period of gas generation and operation cost. Many technologies have been used to produce electricity from LFG before exportation to the grid, such as internal combustion engines (ICEs), turbines, and microturbines according to the production rate of the LFG. For example the amount of methane accumulated in this landfill in the Suhag site (Q = 8415000 m3 / year) for the bioreactor (the maximum power generated from the collected LFG using ICE, turbines, microturbines generator reaches 10 MW, 9MW, and 8.4 design in 2024 respectively, and for the traditional (Q=1143000 m3/ year) and power is 3.2 MW, 2.7MW, 2.9MW, respectively, in 2042.
