The diverse properties of rare earth elements have seen broad and growing applications in clean energy technologies, hybrid vehicles, pollution control, optics, refrigeration, and so on. This study presents a “cradle-to-gate” life cycle assessment of the energy use, resource depletion, and global warming potential resulting from the production of rare earth elements (REEs) using the Bayan Obo rare earth operation in Inner Mongolia, China, as a representative system. The study aggregates data from the literature, LCI databases, and reasonable estimations. A novel economic value-based allocation method for the multiple coproducts of the process is proposed. It is found that four of the high priced REEs scandium, europium, terbium, and dysprosium have very high GWPs from production relative to the rest. A mass-based allocation is also provided for comparison. Impacts on immediate local environment from waste streams that can be toxic are not included in this study.

Sustainable development is a concept, which involves social, ecological and economic objectives, and requires to sustain the integrity of resources exploitation, the direction of investments, the orientation of technological development and institutional change. Although there is still much confusion and conflict about exact meaning of sustainable development, many agree that sustainable development is about satisfying social, environmental, and economic goals. While the concept is generally accepted and relatively easy to comprehend, the difficulty arises in trying to apply the principles of sustainable development in practice. One of the difficulties is need to measure the “level of sustainability”. The desirable characteristics for sustainability indicators have to include: simple to calculate, useful for decision making, and robust in indicating progress toward sustainability. The exergy analysis approach based on full life cycle assessment (LCA) of the materials and technologies is a useful metrics to evaluate mitigation of greenhouse gas (GHG) emissions associated with industrial eco materials and technologies. The metrics is used for reducing dimensionality on the input side by combining material and energy streams and output side reducing different characterisation factors to a single “unsustainability” indicator in a theoretically rigorous manner. The adopted approach has been illustrated on a few examples associated with Australian aluminium industry.
CONFERENCE-ARTICLE 4 Reads 0 Citations Evaluating Sustainability of Using Natural Gas as a Transport Fuel in Comparison of Two Countries: a Life Cycle Assessme... Published: 30 October 2012
For reasons of sustainability, greenhouse gas emissions, and energy security, it becomes necessary to properly evaluate all of possible options for powering transportation fleet for a particular country. When doing this it is equally important to understand all the costs (economic, social, and environmental) and emissions during the fuel extraction, refining and distribution stages as well as the final combustion stage. All steps in the full pathway contribute to the final economic and environmental profile of any given fuel. The natural gas (NG) family of fuels has to be seriously considered as providing for large-scale transportation. From a combustion point of view, NG derivatives have a lower carbon-to-hydrogen ratio than oil-based fuels and should therefore be cleaner, but the upstream emissions of the fuels need to be properly understood. The supply pathways of gaseous fuels are more diverse than the oil-based fuels pathways, because the sources of gas are varied and can imply substantially different emissions profiles. It is therefore important to understand these various pathways for the country under consideration, so that profiles for each country can be documented and policy formulated accordingly. This preliminary study is conducted based on a life cycle assessment (LCA) approach to evaluate potential sustainability of using gaseous fuels (CNG/LNG) for light commercial and passenger vehicles based on conditions in Australia and Ukraine, which are quite different, taking into account information on the production, distribution and use of gaseous fuel. Data for this study are mostly sourced from published literature. The results of the study reveal a significant opportunity for Australia, as well as for Ukraine to increase sustainability of the transport fleet if it takes gaseous fuels on as major source for transport vehicles.
