Life Cycle Energy Consumption and Greenhouse Gas Emissions Analysis of Primary and Recycled Aluminum in China

چکیده
Aluminum production is a major energy consumer and important source of greenhouse gas (GHG) emissions globally. Estimation the consumption GHG caused by aluminum in China has attracted widespread attention because produces more than half global aluminum. This paper conducted life cycle (LC) analysis primary recycled for year 2020, considering provincial differences on both scale self-generated electricity consumed generation grid electricity. Potentials saving reductions were also investigated. The results indicate that there are 157,207 MJ fossil (PE) 15,947 kg CO2-eq per ton ingot China, with LC as high 1.5–3.5 times developed economies. PE very low, only 7.5% 5.3% aluminum, respectively. Provincial-level intensities main areas generally higher while those lower areas. can be significantly reduced decreasing consumption, management, low-carbon development, industrial relocation. Based this study, policy suggestions China’s industry proposed. Recycled restriction electricity, utilization, relocation should promoted they highly helpful reducing industry. In addition, it recommended central government considers among provinces when designing implementing policies.

Life cycle greenhouse gas emissions and freshwater consumption of Marcellus shale gas.
We present results of a life cycle assessment (LCA) of Marcellus shale gas used for power generation. The analysis employs the most extensive data set of any LCA of shale gas to date, encompassing data from actual gas production and power generation operations. Results indicate that a typical Marcellus gas life cycle yields 466 kg CO2eq/MWh (80% confidence interval: 450-567 kg CO2eq/MWh) of gre...

This study estimates the life cycle greenhouse gas (GHG) emissions from the production of Marcellus shale natural gas and compares its emissions with national average US natural gas emissions produced in the year 2008, prior to any significant Marcellus shale development. We estimate that the development and completion of a typical Marcellus shale well results in roughly 5500 t of carbon dioxid...
متن کاملLife cycle energy and greenhouse gas emissions of nuclear energy: A review
The increased urgency of dealing with mitigation of the looming climate change has sparked renewed interest in the nuclear energy option. There exists a substantial stream of research on the amount of embodied energy and greenhouse gas emissions associated with nuclear generated electricity. While conventional fossil fuelled power plants cause emissions almost exclusively from the plant site, t...
