Recycling of WEEEs: An Economic Assessment of present and future e-waste streams
Renewable and Sustainable Energy Reviews, 2015Co-Authors: Federica Cucchiella, Idiano D'adamo, S. C. Lenny Koh, Paolo RosaAbstract:Abstract Waste from Electric and Electronic Equipments (WEEEs) is currently considered to be one of the fastest growing waste streams in the world, with an estimated growth rate going from 3% up to 5% per year. The recycling of Electric or electronic waste (E-waste) products could allow the diminishing use of virgin resources in manufacturing and, consequently, it could contribute in reducing the environmental pollution. Given that EU is trying, since the last two decades, to develop a circular economy based on the exploitation of resources recovered by wastes, a comprehensive framework supporting the decision-making process of multi-WEEE recycling centres will be analysed in this paper. An Economic Assessment will define the potential revenues coming from the recovery of 14 e-products (e.g. LCD notebooks, LED notebooks, CRT TVs, LCD TVs, LED TVs, CRT monitors, LCD monitors, LED monitors, cell phones, smart phones, PV panels, HDDs, SSDs and tablets) on the base of current and future disposed volumes in Europe. Moreover, a sensitivity analysis will be used to test the impact of some critical variables (e.g. price of recovered materials, input materials composition, degree of purity obtained by the recycling process, volumes generated, and percentage of collected waste) on specific Economic indexes. A discussion of the Economic Assessment results shows the main challenges in the recycling sector and streamlines some concrete solutions.

An Open-Source Techno-Economic Assessment Framework for 5G Deployment
IEEE Access, 2019Co-Authors: Edward J. Oughton, Konstantinos Katsaros, Fariborz Entezami, Dritan Kaleshi, Jon CrowcroftAbstract:Optimal network planning is crucial to ensure viable investments. However, engineering analysis and cost Assessment frequently occur independently of each other. Whereas considerable research has been undertaken on 5G networks, there is a lack of openly accessible tools that integrate the engineering and cost aspects, in a techno-Economic Assessment framework capable of providing geospatially-explicit network analytics. Consequently, this paper details an open-source python simulator for integrated modelling of 5G (pysim5G), that enables both engineering and cost metrics to be assessed in a single unified framework. The tool includes statistical analysis of radio interference to assess the system-level performance of 4G and 5G frequency band coexistence (including millimeter wave), while simultaneously quantifying the costs of ultra-dense 5G networks. An example application of this framework explores the techno-Economics of 5G infrastructure sharing strategies, finding that total deployment costs can be reduced by 30% using either passive site sharing, or passive backhaul sharing, or by up to 50% via a multi-operator radio access network. The key contribution is a fully-tested, open-source software codebase, allowing users to undertake integrated techno-Economic Assessment of 5G deployments in a single geospatial framework.

Techno-Economic Assessment of a plant based on a three reactor chemical looping reforming system
International Journal of Hydrogen Energy, 2016Co-Authors: Mohammed N Khan, Tariq ShamimAbstract:Reforming by using chemical looping concept is an innovative and recent technology which is used to convert the hydrocarbon fuels into hydrogen (H2). The overall process produces separate streams of H2 and CO2. The present study conducts a techno-Economic Assessment of a three reactor chemical looping reforming plant. The cost data are used for the plant's location to be in the United Arab Emirates. The effects of key operating parameters on the technical performance of the plant are investigated. In addition, the thermodynamic data from the model are also used to perform an Economic Assessment for calculating the cost of H2 produced. The cost of H2 production with CO2 capture is 1.679 $/kg which is significantly low when compared to the case of steam methane reforming with CO2 capture (about 2.39 $/kg). Furthermore, the cost of H2 production in non-capture scenario is 1.404 $/kg which is comparable with the cost of H2 production from steam methane reforming technology.

Economic Assessment of energy systems with simulation and linear programming
2007 Winter Simulation Conference, 2007Co-Authors: Fermin Mallor, Cristina Azcarate, Rosa BlancoAbstract:Summary form only given. Energy systems based on some natural renewal sources have the drawback of a random input, making them a non reliable supplier of energy. The regulation of the produced energy requires the introduction of new equipment able to storage this energy. The advantage of these transformation-storage systems is that the energy can be sold when the demand is higher and then also the prices are higher. The disadvantages are two, the costs of the new equipments and the lost of energy because of inefficiencies in the transformation processes. Our purpose is to develop a simulation model useful to the Economic Assessment of this type of energy systems. We also consider the analysis of optimal management policies, which are obtained by solving linear programming problems.
