Green Chemistry and Engineering
Published in Matthew N. O. Sadiku, Emerging Green Technologies, 2020
GC is an integral part of GE since it provides the foundation on which to build GE. Sustainable engineering transforms current engineering practices to those that promote sustainability. The relationship between GC, GE, and sustainability is shown in Figure 3.1 [6]. Combining GC with GE at the earliest design stages will maximize efficiency, minimize waste, and increase profitability [6]. From design to disposal, GE is finding ways to balance environmental compatibility with economic profitability.
Sustainability in engineering design
Published in Riadh Habash, Green Engineering, 2017
Sustainable engineering is the process of utilizing energy and other resources at a rate that does not compromise the environment, or the ability of future generations to meet their life needs. Accordingly, SED is a product design where the resources used to make a product should not be depleted, and the usage and eventual disposal of the product should not damage the environment in which it functions.
Sustainable Engineering: Concepts, Principles, and Frameworks
Published in Toolseeram Ramjeawon, Introduction to Sustainability for Engineers, 2020
There is no universal agreement on a definition of sustainable engineering. However, in some specific areas, such as energy, some engineering-related sustainability definitions have been formulated, which emphasize some of the essential points of sustainable engineering. Rosen (2009) defines energy sustainability as the provision of energy services for all people in a sustainable manner, that is, in ways that, now and in the future, are sufficient to provide basic necessities, affordable, not detrimental to the environment, and acceptable to communities and people. Sustainable engineering may thus be defined asthe provision of engineering services in a sustainable manner, which in turn necessitates that engineering services be provided for all people in ways that, now and in the future, are sufficient to provide basic necessities, affordable, not detrimental to the environment, and acceptable to communities and people.(Rosen, 2012) The aim of this chapter is to present a framework for sustainable engineering, which builds on concepts and principles. A concept is the formulation of an idea how to achieve sustainability prior to actually creating it. Principles provide the rules to keep in mind when solving an engineering problem and give more precise guidance for action. We need to be able to set our choices and engineering decisions against these guiding principles for sustainability. Concepts and principles are built upon to construct frameworks. A framework, by definition, is a little loose. It is an approach to solving a problem that provides a rough outline of the methodology that will achieve a specific goal, but that does not identify the specific tools that may be used. A framework is powerful because it provides guidance while being flexible enough to adapt to changing conditions.
The engineering of food with sustainable development goals:policies, curriculums, business models, and practices

Engineering, entrepreneurial, and managerial implications: Sustainable engineering is the art of using various management tools and methods to design, practice, and continuously improve a product to achieve sustainability. This contribution can only be effective and fruitful if the different activities carried out in eco-innovation projects are constantly interrelated and if the local decisions are taken by participants through a systemic view of the project’s performance. For these conditions to be realised, it is essential for students to be trained and able to work in an interdisciplinary manner. This paper is meant to increase the understanding of engineers and teachers about how to practice and teach engineers and young managers about sustainable development practices and policies. This contribution can also encourage established firms and recently graduated food engineers to use their skills and knowledge to help address the growing economic, environmental, and social challenges in agricultural and food systems.
Friction and wear characteristics of vegetable oils using nanoparticles for sustainable lubrication

The ever increasing energy demands and environmental degradations have brought in stringent norms for emission control and energy efficiency. Efforts are being put in globally to reduce the carbon footprint due to industrialisation. The rapidly exhausting non-renewable energy sources, increased crude oil prices, growing environmental consciousness has forced researchers globally to look for sustainable engineering solutions. Around 18% of the contribution to green house effect is by the transportation industry itself [1]. Moreover, an increase in 37% energy requirements in transportation sector was reported from 1990 to 2005, which further poses a threat to the environment by way of harmful emissions [2,3]. It has been reported that 30% of the total energy losses are caused due to the combined effect of friction and wear only [4].
