Economics of Energy and Green Growth
Published in Muhammad Asif, Handbook of Energy Transitions, 2023
Since the economic growth of the last century is inefficient because of the close and inverse relationship between the progress of humankind and the global environmental quality, anthropogenic pressures on the environment have increased, which in turn contributes to the problem of global warming. To face environmental degradation and to improve resource efficiency, 12th goal of the Sustainable Development Goals (SDG 12) aims to achieve sustainable production and consumption. Furthermore, target 8.4 of the SDGs aims to improve global resource efficiency in consumption and production and makes an effort to decouple economic growth from environmental degradation. It is obvious that a shift in policy-making is required toward acknowledging more the need for an integrated approach to production and consumption when environmental impacts are addressed. In this way, decoupling the economic growth from resource use and associated environmental impacts may be rendered easier (Sanyé-Mengual et al., 2019).

In the manufacturing industry, sustainability is becoming increasingly relevant. Progress in sustainable production is critical for reducing the negative environmental consequences [1]. Turning processes justify a significant approach to the industry's metal cutting activity [2]. From the primary cutting region and the cutting insert, the steady heat flux flows into the work piece, causing extremely higher temperatures and a significant thermal expansion for prolong cutting times [3]. High temperatures develop in the region of the tool cutting edge during machining process and further accelerate the tool wear of the cutting tool and the friction between the formed chip and the tool [4]. Despite various favourable characteristics, Ni-based super alloys are reckoned as reduced machinability materials [5]. Nickel-based super alloys provide higher strength, thermal stability and outstanding thermal fatigue properties [6]. Because of the poor machining characteristics of nickel-based super alloys generates from the work hardening effect, it becomes significant to control at machining conditions that further lead to prolonged tool life [7]. The important characteristics of Nimonic 90 i.e. one of the Nickel-based alloys have low thermal conductivity, higher strain hardening that minimises the machining characteristics. [8].
Material Resources in Sustainable Project Management

There is no doubt that the goal of sustainability engineering is to develop production processes that create as little waste as possible while depending on as few resources as possible (Cohen 2011: 21). Production carried out in an environmentally and socially responsible manner is called sustainable production or clean production. Clean production results in sustainable products, which are discussed in Section 4.5. Sustainable production is based on renewable, recycled, and rapidly and harmlessly degradable raw materials and consumables. For example, instead of using standard plastic to make disposable cups, a manufacturer uses biodegradable plastic (Ecovio). The raw materials and consumables used in sustainable production must meet high environmental and social standards. This requires the appropriate selection of suppliers. The products they supply in the form of raw materials, consumables, components, and parts should not contain harmful substances and should be manufactured in conditions that respect workers' rights and ethics. Organic farming of animal husbandry is a good example of sources of raw materials for sustainable food production.
A review on sustainable alternatives for conventional cutting fluid applications for improved machinability

Though conventional metalworking fluids are capable of reducing cutting temperatures, environmental constraints, economic demerits, and worker health considerations have compelled the industrial sector to shift to an environmentally friendly and sustainable machining technique. There are several non-governmental organizations (NGOs) and severe governmental regulations that protect the environment by enforcing industry regulations. Government legislation has prohibited companies from violating the law and discharging dangerous emissions into the environment. In such a conflicting situation, it is preferable to create a forward-thinking paradigm that may yield financial gains without sacrificing ecological preservation. Sustainable Manufacturing (SM) is one of these approaches, which incorporates environmental and economic elements of the industry. Sustainable manufacturing is the production of manufactured goods using cost-effective procedures that effectively limit negative impacts on the environment while preserving energy and natural resources. Sustainable production benefits the workforce, the community, and product safety. According to many researchers, the usage of cutting fluids in large quantities for machining will not be a sustainable way of manufacturing goods. Hence, there is a need for an alternative method of lubrication and cooling during the machining process (Chetan et al., 2015a; A. M. Khan et al., 2020; Sankaranarayanan et al., 2021) (Figure 3).
Key improvement decision analysis mechanism based on overall loss of a production system
Published in Journal of Industrial and Production Engineering, 2021
To reduce the negative influence of production systems on the environment, countries worldwide regard sustainable production as the ultimate goal. It largely involves resource and material conservation and practicing good waste management system. Issues of material waste and overall material usage efficiency in the manufacturing process influence both the environment and the profitability of businesses [2,4]. An example is the original equipment manufacturing industry of mid- to low-end hand tool products. Screwdrivers and pliers composed of steel blades and plastic handles are produced. The material used to manufacture steel blades is steel bars. The material attrition rate is high due to the physical properties of the metal as well as the requirement of various computer numerical control (CNC) processes and heat treatment. Consequently, in this age of small profits, manufacturing process loss and other problems require urgent solutions in the industry.
Reducing waste in manufacturing operations: bi-objective scheduling on a single-machine with coupled-tasks

Sustainable production is defined as ‘the creation of goods and services using processes and systems that are non-polluting; conserving of energy and natural resources; economically viable; safe and healthful for workers, communities, and consumers; and socially and creatively rewarding for all working people’ (Lowell Center for Sustainable Production 1998). In the recent years, more and more research has been devoted to it as a possible answer to the environmental issues affecting industrial companies, such as stricter regulations, highly volatile energy prices, shortage of raw materials and natural resources or customer demand for more environmentally responsible products (Giret, Trentesaux, and Prabhu 2015). As a key factor in production efficiency, operations scheduling is one of several levers that can be used in order to address those problems. In a literature review of sustainability in manufacturing operations scheduling, Giret, Trentesaux, and Prabhu (2015) show that concerns have been mostly focused on the reduction of energy consumption thus far; detailed reviews on energy-efficient scheduling can be found in Gahm et al. (2016) and Biel and Glock (2016). Giret, Trentesaux, and Prabhu (2015) also emphasise the need to address the consequences of scheduling implementation, notably waste, to design sustainable scheduling systems, since there are few works on this topic.
