Application of environmentally conscious manufacturing strategies for an automotive component

Application of appropriate environmentally conscious manufacturing strategies enables the sustainable development of products and processes. Automotive component manufacturers recognise the potential of applying appropriate strategies for attaining Triple Bottom Line benefits. In this context, three strategies such as eco-efficiency, waste minimisation and material efficiency are being applied to minimise environmental impacts associated with the manufacture of automotive products and its associated processes. A case study of an automotive component manufacturing firm has been exemplified. After conducting the study, the potential environmental impact was reduced by 20% and eco-efficiency was improved by 13%. Further, improvements have been observed in terms of overall resource consumption and material efficiency. The overall power consumption was reduced by 18% and weight of the component was reduced by 11%. The study aimed at improving the sustainable performance of product by incorporating green and environmentally friendlier manufacturing practices.

Transforming systems of consumption and production for achieving the sustainable development goals: moving beyond efficiency

The United Nations formulated the sustainable development goals (SDGs) in 2015 as a comprehensive global policy framework for addressing the most pressing social and environmental challenges currently facing humanity. In this paper, we analyse SDG 12, which aims to “ensure sustainable consumption and production patterns.” Despite long-standing political recognition of this objective, and ample scientific evidence both on its importance and on the efficacy of various ways of promoting it, the SDGs do not provide clear goals or effective guidance on how to accomplish this urgently needed transformation. Drawing from the growing body of research on sustainable consumption and production (SCP), the paper identifies two dominant vantage points—one focused on promoting more efficient production methods and products (mainly through technological improvement and informed consumer choice) and the other stressing the need to consider also overall volumes of consumption, distributional issues, and related social and institutional changes. We label these two approaches efficiency and systemic. Research shows that while the efficiency approach contains essential elements of a transition to sustainability, it is by itself highly unlikely to bring about sustainable outcomes. Concomitantly, research also finds that volumes of consumption and production are closely associated with environmental impacts, indicating a need to curtail these volumes in ways that safeguard social sustainability, which is unlikely to be possible without a restructuring of existing socioeconomic arrangements. Analysing how these two perspectives are reflected in the SDGs framework, we find that in its current conception, it mainly relies on the efficiency approach. On the basis of this assessment, we conclude that the SDGs represent a partial and inadequate conceptualisation of SCP which will hamper implementation. Based on this determination, this paper provides some suggestions on how governments and other actors involved in SDGs operationalisation could more effectively pursue SCP from a systemic standpoint and use the transformation of systems of consumption and production as a lever for achieving multiple sustainability objectives.     

Sustainable Everyday Life and Celebrity Environmental Advocacy in Hugh’s War on Waste

ABSTRACT

This study employs Hugh Fearnley-Whittingstall’s television program, Hugh’s War on Waste, to explore representations of sustainable everyday life and the functions of celebrity environmental advocacy. The analysis is located within broader understandings of the discursive and contested nature of sustainability and the representative functions of environmental celebrities who act as figures of both distinction and equivalence. It discusses Fearnley-Whittingstall within the context of the stable of celebrity chefs, and it demonstrates how Hugh’s War on Waste is an example of the burgeoning televisual genre based on forms of campaigning about food issues. The analysis specifically explores how Hugh’s War on Waste is informed by: narratives of self-transformation where individuals are marshaled into appropriate practices of waste management and sustainability, presentations of the pleasures associated with such practices, and revelations of the networks of food production, distribution and consumption across the contexts of domestic everyday life, farms, supermarkets, and other corporations.     

Towards integrating production and consumption to reduce consumer food waste in developed countries

Abstract

Literature analysing reasons for Consumer Food Waste (CFW) revealed that it cannot be reduced to consumer behaviour alone. In fact, CFW should not be conceptualised as the problem but as a symptom of a food system that oversupplies and encourages consumerism. This research focuses on preventing CFW in the United Kingdom (UK), as a representative of a developed country, by improving the traditional food provisioning system to better integrate production and consumption. To achieve this, five stages are identified to design a sustainable product service system (PSS) capable of supporting consumers to better manage their food operations: (1) strategic analysis of current food provisioning system, (2) exploring system level innovations leading to minimisation of CFW, (3) refinement and selection of PSS, (4) designing the most promising PSS from an environmental, economic and social perspective, and (5) evaluating designed PSS. This paper considers the first of these stages, reviews reasons for and existing solutions to CFW, and provides a strategic analysis of the current food provisioning system to identify characteristics that could be exploited within a new PSS. Initial investigations reveal applicability of PSS concept to the food provisioning system and potential for reduction of CFW if core causes are addressed.     

Sustainability risk identification in product development

Sustainability-related issues present significant financial, strategic, compliance and operational risks to manufacturers. Many of these risks directly or indirectly result from the way a product is designed and managed across its life cycle. Assessing sustainability risk (S _R) at the product design stage is crucial for the development of products that both minimise sustainability risk exposure and are environmentally sustainable. Managing the costs associated with these risks requires risk management intervention at the design stage before these costs are committed throughout the life cycle (production, use, end-of-life). The goal of the sustainability risk assessment (SRA) methodology is to provide an approach to comparing the financial cost of a ‘sustainable product’ vs. an ‘unsustainable product’, by factoring in the effects of S _R on life-cycle cost. The SRA methodology demonstrates that, in some cases, sustainable products cost less than unsustainable products when sustainability risk is considered in the costing analysis. This paper outlines the first step of the SRA methodology, which is a process for identifying S _R inherent in the product life cycle. Once key risks are identified, the subsequent steps of the SRA assess and prioritise these risks for treatment through changes to product design and materials composition.     

Circular Makerspaces: the founder’s view

Abstract

Makerspaces – open access design and fabrication workshops – provide new contexts for design practice through ‘distributed production’. The global community of makerspaces has evolved quickly and in turn, substantial hype is attributed to its potential for radical sustainable innovation. In this article, we explore this potential in the context of the new ‘circular economy’ agenda. We focus the research on the critical role of makerspace managers/founders who are recognised as gatekeepers to circular practices. The research method is action-led including expert interviews (academics and founders/managers) as well as two generative context-mapping workshops, run at selected makerspaces in collaboration with their founders/managers. We unearth everyday ‘how-to’ guidance to interweave circular practices within makerspaces from the outset by: fostering an enabling culture; building local connections; nurturing individual/community capacities; and stimulating practical know-how. However, while the research reveals immense opportunities to cultivate circular literacy from within makerspaces, the prospects to ask more profound questions about our economy, through makerspace practices, are found to be compromised by day-to-day concerns. The insights from this research can act as a starting point for future work in this emerging research area.     

Study on Management and Control of Nonpoint Source Pollution from Urban Surface Runoff

Abstract

Urbanization is the dominant form of land-use change in terms of impacts on water quality, hydrology, physical properties of watersheds and their nonpoint source (NPS) pollution potential at present. Urbanization has changed the source, process and sink of urban NPS pollution, especially raised the pollution load of urban runoff NPS in receiving water. Urban runoff pollution is a hot spot of research on NPS. This paper analyzed type, source and harm of the NPS pollutants of urban runoff and its influence on the receiving water. Through estimating NPS pollution load of urban runoff and summarizing the law and characteristics of urban runoff NPS systemically, study on management and control of urban runoff NPS pollution was focused on the application of BMPs (best management practices). It is a fresh methodology that management and control on NPS pollution from urban surface runoff was analyzed by methods of landscape ecology, environmental economics and environmental management. The paper provided a scientific reference for mitigating urban water environment pressure and an effective method for management and control of NPS pollution from urban surface runoff.     

SWOT Analysis and Challenges of Nile Basin Initiative: An Integrated Water Resource Management Perspective

Abstract

River Nile is one of the longest transboundery rivers and it is shared and used by Burundi, Democratic Republic of Congo, Egypt, Ethiopia, Eritrea, Kenya, Rwanda, Sudan, Tanzania and Uganda. As of today, the Nile is a crucial resource for the economic development of the Nile Basin countries and a vital source of livelihood for 160 million inhabitants as well as 300 million people living in the 10 riparian countries. The Nile Basin Initiative (NBI) is one of the international cooperative river basin management program and regional partnership where all the Nile Basin countries except Eritrea unite to pursue long-term sustainable development, improved land use practices and management. This review therefore focused on the challenges not faced on NBI in terms of integrated use of the river and conducted analysis of strengths, weaknesses, opportunities and threats (SWOT) based on secondary data. The result of the review revealed that for decades, the Nile Basin people have been facing many complex environmental, social, economic and political challenges that have made it difficult for the proper management and sustainability of Nile water. The initiative provides training to develop skills in government ministries, non-governmental organizations and local communities in each country. It is also working to raise awareness of critical environmental issues by strengthening networks of environmental education practitioners; developing curriculum in the education sector. The challenges of NBI include the involvement and funding of World Bank, lack of sufficient staff, procedural and policies conflicts, lack of coordination and linkage with other regional institutions and lack of recognition as river basin organization. Considering the complex nature of the project, it is recommended that the NBI should come up with a strong multi-disciplinary monitoring and evaluation team to follow up all implemented projects. The NBI should carry out participatory land use planning in communities along the river basin. Moreover, livelihood analysis should be carried out especially in communities along the Nile to come up with poverty eradication projects which are socially acceptable, applicable, economically viable and affordable.     

Integration of DFE and DFMA for the sustainable development of an automotive component

The recent developments in manufacturing organizations recognize sustainability as an important value addition for survival in the competitive scenario. The design engineers are in search of approaches for creating environmental conscious products. The purpose of this paper is to report a research carried out for ensuring sustainable product design by the integration of Design for Environment (DFE) and Design for Manufacture and Assembly (DFMA) methodologies. In this context, this paper reports a case study carried out in an automotive component. The candidate product is the charge alternator pulley. The existing pulley has been created using Computer Aided Design. Then sustainability analysis was conducted on the existing component for determining environmental impact. This is followed by the engineering analysis of the component using ANSYS. Then conceptual design changes were developed in the proposed product using DFMA concept. Then the environmental impact has been evaluated in terms of carbon footprint, energy consumption and air/water impacts on proposed product. It has been found that the optimized pulley design possesses minimal environmental impact. The result of the case study indicated that the integration of DFE and DFMA concept could initiate new developments in sustainable designs with minimal impact to the environment and it also reduces the product cost.     

Innovation for sustainable development: from environmental design to transition management

Society needs to adapt in order to provide the wealth that an increasing part of the world population is getting used to. We are on a track to ecological and resource collapse if actions are not taken soon. Technology will have to play a key role in the process of changing industrial society. But innovation has to be embedded in social and organizational innovation. We need sociotechnical change. Environmentally conscious design has been practiced in engineering design for more than a decade. Its merits are sometimes blamed as futile, as the world has not witnessed a significant contribution to the solution of the larger (global) problems. This paper first sketches a scheme of the various levels of technological change, ranging from: (1) incremental optimizations of single artifacts, to (2) major change of artifacts, (3) systems change, and (4) technological transitions (involving changes in production and consumption). It outlines the stakeholders involved in these types of innovations and the parties that could orchestrate the innovation process. In this paper, It is argued that the most encompassing level of technological innovation, the level of transition, is crucial for achieving long-term sustainable development, as it has the largest potential for improvement. However, transition is not very well manageable. The paper contains a review of the literature regarding the occurrence of technological transitions. After a transition has occurred, the new system is often not efficient. Its gains in terms of diminished resource consumption or pollution have to be enlarged by less encompassing innovation strategies, such as systems innovations and product optimization. Transitions for sustainable development are often impossible, as the new systems have to compete with fully developed and optimized systems that have far advanced at the learning curve, i.e., are optimized by various systems and incremental innovations. Less encompassing levels of innovation, even those that aim at more sustainability, can counteract transitions that have more potential for sustainable development by improving the competing (unsustainable) technology. The paper will give several examples of this dilemma and some guidelines for developing government policies as well as corporate strategies. On the policy level, it is argued that it is especially important to develop (scope for) market niches for new sustainable systems and products as they create scope for experiments that could lead to transitions.

Environmental Implication of Intensive Farming Practices on North China Plain

Abstract

The current pressure on production resources of North China Plain, such as land and water to feed the growing population, necessitates the assessment of the sustainability of farming practices. This study focuses on the sustainability of farming practices related to groundwater and soil fertility management. The assessment is based on selected site-specific key indicators and their established threshold limits. The current farming practices in the study area are clearly unsustainable. Only about 6% of the surveyed farm households practice sustainable farming. The study stresses that farming practice, which is economically sustainable, should not be promoted at the cost of environment. Holistic strategies need to be developed and implemented that aim at balanced use of inputs, which satisfy both productivity and environmental concerns.

CAD and DFM: enablers of sustainable product design

Sustainability has been regarded as an important concept for survival in the contemporary scenario. Modern design engineers are in need of approaches for creating sustainable products. In this context, this paper reports a case study carried out in an Indian modular switches manufacturing organisation. The existing handle of the switch has been modelled using computer-aided design (CAD). Then, the sustainability analysis has been carried out for determining the environmental impact. This is followed by the redesign of the handle using design for manufacturability (DFM) principles. The sustainability has been measured in terms of carbon footprint, energy consumption and air–water impacts. It has been found that the redesigned handle possesses minimal environmental impact. It could be inferred from the results of the case study that CAD and DFM could lead to the development of sustainable product design with minimal impact on the environment.     

Population and development: impacts on environmental performance

Population growth and development patterns have a significant impact on the environmental performance. The issue of concern is whether population growth or the consumption/production patterns are responsible for environmental deterioration. This paper is an attempt to capture the impact of technological development, affluence, and population on environmental performance index, while previous studies had captured the impact of these three factors on environment only through CO₂ emissions. The analysis reveals that technological development and population size have a negative impact on environmental performance, whereas measures to improve affluence have a positive impact. Technological development has increased the production of energy efficient products but at the same time consumption of these products has increased manifold leading to environmental deterioration. Demographic attributes need specific attention to improve environmental performance. This paper concludes on some policy reflections on slowing the population growth as well as persuades individuals and economies to relook to their consumption and production patterns and channelize their efforts to protect the environment.     

Cleaner production solution selection for paper making – a case study of Latif paper products Co. Iran

Abstract

The objective of this research is to design an approach for selecting appropriate solutions to efficiently and productively reduce environmental pollution and water, energy and raw material consumption in a recycled paper manufacturing facility, the paper mill in Latif, Iran. To reach this goal, we develop a decision-making model using the Analytic Hierarchy Process (AHP). The proposed model provides a framework for cleaner production implementation specific to the paper industry. Pairwise comparisons of the results of designed questionnaires resulted in the hierarchy model being divided into five major groups: production modification; process change; preventive maintenance; renewal; and manpower resources.These five groups include 31 sub-criteria and seven alternatives. The results showed that process change yields the highest priority among the main criteria and that industrial automation and its technology level gives the highest priority among sub-criteria. Regarding the alternatives, reduction of environmental pollution is the most important solution for cleaner production in the industry. Also, product modification is the most sensitive criterion affecting the alternatives priority.     

The ethics in balancing control and freedom when engineering solutions for sustainable behaviour

Research suggests that to allow for sustainable development, consumption patterns must be changed. Individual behaviour is central to society's impact on the environment. However, due to the complexity of environmental issues, much of the political debate and technology development is inaccessible to consumers and based on the values, interpretations and priorities of experts. User‐centred, user‐involved and participatory processes are fundamental in design disciplines such as interaction design and participatory design. Research into the possibilities for cross‐pollination of design for sustainability and user‐centred design has distinguished several strategies for design‐led behavioural change. The strategies differ with regard to the levels of control and responsibility that users are left with, ranging from empowerment through information about consequences of behaviour to blocking behaviour or forcing sustainable practices upon individuals. By considering technological behaviour‐steering strategies in the light of science and technology studies and theory on technological mediation, the paper addresses the ethical issues that arise and discusses how designers can contribute to more sustainable consumption patterns without compromising quality of life, individual freedom and democratic rights.     

Design concept for an ecological relaxing textile product using solar energy

We can enhance our quality of life and reduce environmental impacts by making improvements in textile product design. By thinking about the environment when we design, choose and use technology, we can play an important part in building a better world for the future. If we are going to live in a sustainable way, the technology that we use has to be sustainable.

This paper provides an insight into how the design of textile products could provide for a more sustainable future. It describes a design concept for an ecological relaxing textile that uses photovoltaic cells to collect and store solar energy and to power an electronic relaxing system. This design may help improve our quality of life now and in the future.

The raw materials and processes, the electronic devices and the dimensions of solar energy for this application are analysed from an environmental perspective. The solar relaxing textile can facilitate our daily life by providing increased comfort and well being, and also acts as an indirect message to use renewable energy within textile support, in order to preserve our ecology.     

Celebrity vegans and the lifestyling of ethical consumption

ABSTRACT

Veganism offers an important critique of unethical and unsustainable food production practices, yet vegans have been historically stigmatized in mainstream media. Given the recent prominence of celebrity vegans, this article asks, how might the cultural intermediary work of vegan celebrities make the ethical practice of veganism more accessible? And how do vegans’ ethical concerns about the exploitative production and consumption of animals as food and byproducts get reframed in the context of celebrity consumer culture? Bringing together philosophies of ethical veganism and eco-feminism with literature on ethical (food) consumption and celebrity culture, this article analyses the educational campaigning work on veganism by Hollywood actor, Alicia Silverstone and TV chat show host, Ellen DeGeneres. It finds that veganism is figured as a diet and lifestyle that foregrounds an ethics of care, compassion, kindness and emotion – about and for humans, animals and environment – consistent with ethical veganism. Yet these ethics are reworked through the commodity logic of celebrity culture to make it more marketable and thus consumable as a set of ideas and gendered lifestyle practices, where the individual choice is to be a healthy, happy and kind self. The tensions between ethical veganism as an intervention at the point of consumption within the production of exploitative and gendered human/animal/environmental relations, and the focus upon an individualized lifestyle politics through which celebrities maintain their commodity status, thus coalesce in the work of celebrity vegans.
