Life Cycle Assessment of the Separation and Recycling of Fluorinated Gases Using Ionic Liquids in a Circular Economy Framework.

ABSTRACT: The stricter regulation regarding the use of fluorinated gases (F-gases), as a consequence of their high Global Warming Potential (GWP), represents a challenge for the refrigeration industry. The design of alternatives requires the recycling of the low to moderate GWP compounds from current refrigerant blends. However, there is not a developed and standardized technology available to recover them, and once the life cycle of the refrigeration equipment has ended, most gases are incinerated. Fluorinated ionic liquids (FILs) can effectively perform as absorbents to the complex separation of F-gas mixtures. In this work, a methodology based on the COSMO-RS thermodynamic package integrated into an Aspen Plus process simulator was used to evaluate the performance of an FIL to recover difluoromethane (R-32) from the commercial blend R-407F. The environmental sustainability of the recovery process (circular economy scenario) was analyzed with a life cycle assessment (LCA) approach, comparing the obtained results with the conventional R-32 production (benchmark scenario). The results reveal a 30% recovery of 98 wt % R-32 suitable for further reuse with environmental load reduction in the 86-99% range compared to the R-32 production. This study can guide the development of new F-gas recovery technologies to improve the environmental impacts of these compounds from a circular economy perspective.

Project description:Municipal Solid Waste (MSW) management has been a long-standing problem for many cities in developing countries. Urbanization, population growth, and excessive demand for resources caused significant waste related environmental and socio-economic problems in cities. Integration of policy decisions with actionable targets and management of economic and environmental extremes were common challenges to achieving sustainable waste management strategy. Circular economy is a concept that has been evolved with sustainable resource management perspective adopted in this study to support scientific decision-making process for urban planners and policymakers. Life Cycle Assessment (LCA) is a framework to assess the environmental impacts of waste life cycle ranging from waste generation, transportation, treatment, and end disposal. This study used the LCA framework to evaluate the impact of MSW management of a selected local authority in Colombo, Sri Lanka, to identify the environmental impact of four (04) proposed scenarios in comparison with the Business-As-Usual (BAU) scenario. Environmental impacts were calculated using global warming potential in terms of greenhouse gas emissions and short-lived climate pollutants. The results revealed that management of MSW within the local authority boundary by integrating recycling, incineration, and sanitary landfill (3:8:1 ratio) offered the highest positive impacts (- 121.84 kg of CO2 eq./ton) while BAU scenario caused the highest negative impacts (250.97 kg of CO2 eq./ton) in comparison with selected scenarios. Moreover, incineration, sanitary landfill, recycling, and anaerobic digestion contributed to emission savings and energy generation. LCA framework was used to identify the composition of MSW for suitable technologies as well as to evaluate the efficiency of existing management mechanisms within a local authority. Evaluation was used to understand the holistic picture of multiple management options to support policymakers in the decision-making process. This framework can be used as a benchmarking tool and bridging concept between the waste management policy and local action plans, which is an important step towards achieving a circular economy for developing countries.Supplementary informationThe online version contains supplementary material available at 10.1007/s43615-022-00200-x.
