Economic and environmental strategies for process design

This paper first addresses the definition of various objectives involved in eco-efficient processes, taking simultaneously into account ecological and economic considerations. The environmental aspect at the preliminary design phase of chemical processes is quantified by using a set of metrics or indicators following the guidelines of sustainability concepts proposed by . The resulting multiobjective problem is solved by a genetic algorithm following an improved variant of the so-called NSGA II algorithm. A key point for evaluating environmental burdens is the use of the package ARIANE™, a decision support tool dedicated to the management of plants utilities (steam, electricity, hot water, etc.) and pollutants (CO2, SO2, NO, etc.), implemented here both to compute the primary energy requirements of the process and to quantify its pollutant emissions. The well-known benchmark process for hydrodealkylation (HDA) of toluene to produce benzene, revisited here in a multiobjective optimization way, is used to illustrate the approach for finding eco-friendly and cost-effective designs. Preliminary biobjective studies are carried out for eliminating redundant environmental objectives. The trade-off between economic and environmental objectives is illustrated through Pareto curves. In order to aid decision making among the various alternatives that can be generated after this step, a synthetic evaluation method, based on the so-called Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) (), has been first used. Another simple procedure named FUCA has also been implemented and shown its efficiency vs. TOPSIS. Two scenarios are studied; in the former, the goal is to find the best trade-off between economic and ecological aspects while the latter case aims at defining the best compromise between economic and more strict environmental impact

Developing an approach to assess the influence of integrating disaster risk reduction practices into infrastructure reconstruction on socio‐economic development

Purpose – Disasters provide physical, social, economic, political and environmental development windows of opportunity particularly through housing and infrastructure reconstruction. The reconstruction process should not be neglected due to the opportunistic nature of facilitating innovation in development. In this respect, post‐disaster “infrastructure” reconstruction plays a critical role in development discourse and is often essential to sustain recovery after major disasters. However, reconstruction following a natural disaster is a complicated problem involving social, economic, cultural, environmental, psychological, and technological aspects. There are significant development benefits of well‐developed “Disaster Risk Reduction (DRR) Strategies” and, for many reasons, the concept of DRR can be more easily promoted following a disaster. In this respect, a research study was conducted to investigate the effects of integrating DRR strategies into infrastructure reconstruction on enhancing the socio‐economic development process from a qualitative stance. The purpose of this paper is to document part of this research study; it proposes an approach that can be used to assess the influence of the application of the DRR concept into infrastructure reconstruction on socio‐economic development. Design/methodology/approach – The research methodology included a critical literature review. Findings – This paper suggests that the best way to assess the influence of integrating DRR strategies practices into infrastructure reconstruction on socio‐economic development is to assess the level of impact that DRR strategies has on overcoming various factors that form vulnerabilities. Having assessed this, the next step is to assess the influence of overcoming the factors that form vulnerabilities on achieving performance targets of socio‐economic development. Originality/value – This paper primarily presents a framework for the concept of socio‐economic development and a modelled classification of DRR practices

Design for manufacture and sustainability in new product development

Design for manufacture is well recognised by industry and is about optimising design to aid production. Today there is a significant and growing trend of recognising what happens to a product once its user phase has finished. Post-consumer processes are now an important consideration during the ab-initio stages of design. Rather than a focus limited to design for manufacture or (more recently) design for assembly now the pressure is on for post consumer design. Companies need to do this because legislative pressures are increasing and consumers are becoming ever more aware of, and concerned about, environmental issues. End-of-life processing and design for the environment are therefore areas of growing of interest. This conference paper investigates with industry practitioners their experiences regarding for both the environmental and economic advantages of product life-cycle planning. Legislative pressures and consumer awareness are driving businesses to develop sustainable product design strategies (Jones et al, 2001 p. 27). Changes within the law, to protect our environment, cause companies to pay attention as they begin to affect profitability. The first British Standard to address design for end-of-life processing, and therefore support industry, is BS 8887-1. Over 60 UK manufacturing and design companies that had bought BS 8887-1 contributed to this by being interviewed or providing a written response. The research investigated multiple aspects of sustainable design in practice however, in this conference paper the focus is its application within the design process

A financial social accounting matrix for the integrated macroeconomic model for poverty analysis : application to Cameroon with a fixed-price multiplier analysis

Cameroon is engaged in the Poverty Reduction Strategy Paper (PRSP) process, which emphasizes increased focus on poverty reduction in the design and implementation of growth and adjustment strategies. The Integrated Macroeconomic Model for Poverty Analysis (IMMPA) recently developed at the World Bank provides an analytical structure for supporting the PRSP process and quantifying poverty reduction strategies. Drawing on that framework, the authors provide a detailed financial social accounting matrix (SAM) for the Cameroonian economy to serve as input into the construction of an IMMPA model for Cameroon. An analysis of this financial SAM shows that the dramatic fall in investment during the crisis period persisted in the post-devaluation growth period in the late 1990s. Continued low investment has implications for ongoing high unemployment rates and poor welfare indicators. The authors illustrate this with simulations based on fixed-price multiplier analysis that highlight the potential growth and welfare benefits of increased public investment, following hypothetical debt relief and reduction of external debt servicing within the framework of the heavily indebted poor countries initiative.Economic Theory&Research,Labor Policies,Health Economics&Finance,Environmental Economics&Policies,Banks&Banking Reform,Environmental Economics&Policies,Economic Theory&Research,Poverty Assessment,Achieving Shared Growth,Banks&Banking Reform

Beyond sustainable buildings: eco-efficiency to eco-effectiveness through cradle-to-cradle design

Sustainable building development focuses on achieving buildings that meet performance and functionality requirements with minimum adverse impact on the environment. Such eco-efficiency strategies are however not feasible for achieving long-term economic and environmental objectives as they only result in damage reduction without addressing design flaws of contemporary industry. The cradle-to-cradle (C2C) design philosophy which has been described as a paradigm changing innovative platform for achieving ecologically intelligent and environmentally restorative buildings appears to offer an alternative vision which, if embraced, could lead to eco-effectiveness and the achievement of long-term environmental objectives. Adoption of C2C principles in the built environment has however been hindered by several factors especially in a sector where change has always been a very slow process. From a review of extant literature, it is argued that the promotion of current sustainable and/or gree n building strategies - which in themselves are not coherent enough due to their pluralistic meanings and sometimes differing solutions - are a major barrier to the promotion of C2C principles in the built environment. To overcome this barrier to C2C implementation, it is recommended that research should focus on developing clearly defined and measurable C2C targets that can be incorporated into project briefs from the inception of development projects. These targets could enable control, monitoring and comparison of C2C design outcomes with eco-efficient measures as well as serve as a guide for project stakeholders to achieve eco-effective “nutrient” management from the project conceptualization phase to the end of life of the building

Design for Sustainable Healthcare in a European context. A comparative analysis of Sustainable Healthcare and Design strategies in three European case studies.

In recent years, interest in Sustainable Healthcare has grown globally: many environmental issues are attracting great interest because they also represent a high cost for National Health Services. Resource consumption and waste production have huge environmental and economic impacts, deeply affecting the costs of medical treatments. Much research in recent years has focused on education and policy strategies to face these issues, but Design research could play a key role to integrate them, acting upstream the production process. This study aims to provide an overview on different European approaches to Sustainable Healthcare and Design for Healthcare, defining potentials and limitations to their development. The developed methodology combines two different levels of analysis, including macro (region) and micro (hospital and wards) environmental issues. The analysis has been applied to three different European case studies (from Italy, Sweden and Denmark). This allowed to highlight pros and cons of current international scenarios in regards of Sustainable Healthcare and Design strategies and their implementation

Design strategy of a compact unglazed solar thermal facade (STF) for building integration based on BIM concept

This paper discusses the specific design strategy of a novel compact unglazed Solar Thermal Facade (STF) for building performance research in architectural practice. It identifies the basic role of such STF in the building performance simulation and analysis. A dedicated design strategy based on the BIM (building information modelling) concept for application of the proposed STF is then developed in details. This research work clarifies the necessary steps in ensuring that the environmental/economic factors and energy-efficiency strategies of the STF are integrated with the building design and analysis process at the early stage

Weighting with Life Cycle Assessment and Cradle to Cradle: a methodology for global sustainability design

Sustainable product design uses methodologies focused on eco-effectiveness and eco-efficiency for the proposal of innovative technological solutions and for the control of environmental impacts during the product life cycle. One of the main drawbacks of such techniques is their qualitative nature, associated with a decision-making process that is sometimes arbitrary, or with unverifiable data; this means that several complementary tools are currently being used to reduce the error in the results obtained. This situation makes the unification of procedures necessary. In this context, this research develops a methodology for the sustainable design of industrial products that integrates life cycle assessment (in its environmental, economic and social application) and cradle-to-cradle techniques. For this purpose, a new assessment process is proposed, based on damage, developing LCA+C2C endpoint indicators. The methodology is subsequently verified in a case study of products for sustainable mobility (city trike electric). The results show that an integrated LCA+C2C assessment can help to propose more balanced sustainable strategies and would be a suitable method to measure tradeoffs between economic, social and environmental results, for practical purposes and future redesigns. The unified method provides a procedure to design a solution with a trade-off between eco-efficient and eco-effective criteria; it also simplifies the design phases, facilitates the interpretation of the results and provides a quantitative scope to the cradle-to-cradle framework

Sustainability Assessment & Energy Efficiency Oriented Simulation

Sustainability assessment is considered as one of the crucial strategies to realize sustainable design and manufacturing process. In this talk, I will present a modular design methodology for achieving sustainable design as well as fulfilling functional requirements with a novelty 6R concept (reuse, recycle, reduce, recover, redesign, and remanufacture). For the sustainable assessment of machining process, a new approach was proposed on the consideration of environmental, economic, and social criteria for selecting the optimal machining strategy from sustainable manufacturing viewpoint. Then, an energy consumption modeling was developed to characterize the relationship between machining process variables and energy consumption for material removal processes based on thermal equilibrium and empirical modelling. Face milling test was conducted on CNC machining center to illustrate validity of the proposed method to define sustainability performance of machining process, and optimize the energy-saving of a machining worksho

Climate Policy and Economic Growth in Developing Countries

Although developing countries face a drastic increase in their greenhouse gas emissions, mitigation actions against climate change do not rank high among their priorities. The obvious reason lies in the necessity for them to continue the development process, which is characterised by pressing needs other than emission control. For developing countries the real problem is thus not emissions but economic growth. Therefore the key question is whether or not the Kyoto Protocol provides an opportunity for growth and thus for their economic development. The only way to accelerate the participation of developing countries in climate agreements - and therefore to come closer to the goal of a global climate control - is to design strategies which enable their economic development. The dilemma of reducing emissions on a global scale while ensuring growth in the poorer regions can only be solved if there are possibilities embedded in the agreements which can contribute to the sustainable development of those regions. As a consequence, greater emphasis must be placed on the economic development dimension of the Kyoto Protocol as far as the impact on developing countries is concerned.Climate Policy, Environmental Modeling, Integrated Assessment, Technical Change
