Life Cycle Assessment and Other Assessment Tools for Waste Management and Resource Optimization
The waste streams of society contain a substantial potential of material and energetic resources. The benefits of its utilization, however, depend on the waste management strategy applied. The present study aims at environmentally optimizing the Swiss municipal solid waste (MSW) management system by using the combination of material flow analysis (MFA), life cycle assessment (LCA), and mathematical optimization techniques. MFA supports decisions in resource management providing an understanding of the waste management system, providing information about capacities of treatment options, and assists in priority setting (Brunner and Rechberger 2004). MFA does, however, not provide information on the environmental impacts associated …

CO2 Summit II: Technologies and Opportunities
Carbon dioxide (CO2) capture and storage (CCS) systems alleviate global climate change through the subsurface storage of CO2 emission. This CCS technology can be costly, but CO2 Capture, Utilization, and Storage (CCUS) approaches can decrease the cost of CCS, because sequestered CO2 is used to produce an economically viable commodity. In one CCUS application, CO2 that is sequestered in sedimentary basins during the CCS process can be used to extract geothermal heat that can then be used to generate a profit1,2. These CO2-geothermal systems rely on the temperature of …
