Economic and Environmental Evaluation of design for active disassembly
Journal of Cleaner Production, 2017Co-Authors: Jef R. Peeters, Paul Vanegas, Wim Dewulf, Joost R. DuflouAbstract:Prior research has demonstrated that a disassembly based end-of-life (EoL) treatment for electronic products is characterized by the highest recovery rates for precious metals (PMs) and non-commodity plastics, such as flame retardant plastics. Nonetheless, EoL electronic products are nowadays also commonly recycled without disassembly in different types of size-reduction based treatments or in an integrated PM smelter-refinery. This disparity of recycling processes adopted worldwide resulted in a high uncertainty on the EoL treatment processes that will be adopted for discarded electronic products. As a result, governments, original equipment manufacturers and recycling companies struggle to determine the economic and Environmental value of design for disassembly. For this reason, a methodology is presented to calculate the Composite Rate of Return (CRR) on investing in design for disassembly and the resulting Environmental impacts. This methodology is applied to evaluate the economic and Environmental benefits of implementing three types of active fasteners for eleven electronic products which are available in both a product service system (PSS) and a traditional sales oriented business model. The performed analyses demonstrate that the preferred EoL treatment, as well as the economic and Environmental benefits of implementing design for active disassembly, strongly depends on several product properties and boundary conditions. Based on the performed sensitivity analysis, the application of active pressure and temperature sensitive fasteners is expected to be only economically viable for products placed on the market in a PSS context, in which they will be separately collected with a high collection rate. Furthermore, impulse sensitive elastomer based fasteners are characterized with the highest rate of return and considered to be suited for both products sold in a traditional sales oriented business model and for products used in a PSS.

integration of the calcium carbonate looping process into an existing pulverized coal fired power plant for co2 capture techno economic and Environmental Evaluation
Applied Energy, 2018Co-Authors: Angela Rolfe, Ye Huang, Martin Haaf, S Rezvani, D Mcliveenwright, Neil HewittAbstract:This work focuses on the techno-economic and Environmental Evaluation for an existing pulverised coal-fired power plant retrofitted with the calcium carbonate looping (CCL) process. The CCL process is an attractive technology due to relatively low efficiency penalties. To better understand the performance characteristics and benefits of systems integration, the steady-state model for the CCL process, developed in ECLIPSE, was used to perform a techno-economic analysis. The simulation results showed that the net efficiency for the selected 600 MW PC power plant equipped with the CCL process was 33.8% (lower heating value) at 94% CO2 capture ratio. With respect to the reference plant without CO2 capture, this resulted in a lower efficiency penalty (7.4% points). The capital cost and maintenance and operating costs were estimated according to a bottom-up approach using the information gained through the mass and energy balance. Specific investment was found to be €1778/kWe, which is approximately 21% higher than for the reference plant. The levelized cost of electricity would be €77.3/MWh with CCL CO2 capture. The CO2 capture cost and CO2 avoidance cost relative to the corresponding reference plant were €16.3/tCO2 captured and €22.3/tCO2 avoided, respectively. The SimaPro software was used to perform a life cycle analysis of the capture technology to determine its Environmental impact. The results illustrated that the overall climate change impact had been reduced by 75%, while the fossil depletion impact was increased by 22%.

active solar heating systems for energy efficient buildings in greece a technical economic and Environmental Evaluation
Energy and Buildings, 2014Co-Authors: Georgios Martinopoulos, Georgios TsalikisAbstract:Abstract The purpose of this study is the technical and economic Evaluation of a typical solar space and water heating system, utilized in an 88 m 2 detached house that is designed according to the latest Greek Regulation on the Energy Performance of Buildings as a means toward Nearly Zero Energy Buildings (NZEB). The analysis was conducted for each of the four climatic zones designated in the Greek Regulation. A financial analysis was performed and the Net Present Value and the Discounted Payback Period (DPBP) were calculated and correlated with the solar systems collector area and the storage tank volume. Furthermore, the annual avoided emissions from the substituted fossil fuels are estimated for the solar systems considered. The analysis demonstrates that the typical solar space and water heating system can provide a viable solution toward NZEB with solar coverage and DPBP being strongly influenced by the climatic zone of the building and the type of fossil fuel substituted. In all cases the solar system covers at least 45% of the total heating loads while the payback period is as low as 4.5 years with an annual abatement of more than 50 t of CO 2 in the worst case scenario.

an assessment tool for the energy economic and Environmental Evaluation of thermal insulation solutions
Energy and Buildings, 2009Co-Authors: D Anastaselos, Efrosini Giama, Agis M PapadopoulosAbstract:Abstract The paper discusses an assessment tool, used for the energy, economic and Environmental Evaluation of Thermal Insulation Solutions (TIS). The results of the assessment undertaken with this tool can take the form of a simple rating system in order to enable users to perform comprehensive comparisons amongst various building materials and TIS. A ranking expressed by A, B and C classes is used for energy, Environmental and economic parameters. By evaluating the materials, the tool supports the users to make decisions, depending on preferences or priorities such as the energy efficiency achieved, the total cost and the Environmental performance. The assessment tool is applied for the double cavity wall and the External Thermal Insulation Composite Systems (ETICS) as they are used throughout Europe, both in new constructions and in the renovation of existing buildings.
