A common factor for industrial production is energy, and the level of energy consumed is typically used to measure the growth and economic development of countries. However, as the industrial sector expands and makes efforts to gain competitive advantage, there is a growing concern regarding energy consumption and the ecological burden related to energy use. Thus far, industry has relied on the Lean manufacturing paradigm to gain the contemporary benefits of profitability, flexibility, and increased efficiency. More recently, the association of Lean manufacturing and environmental impacts has grown in both the industrial and academic fields. The main aim of this research is to investigate the correlation between lean tools and their effect on Green House Gas emissions, ultimately measuring environmental performance. The research is quantitatively based and entails the study of a weld process production line at Toyota South Africa Motors. The environmental impacts of the production process were observed and measured before and after the implementation of three lean tools: Value Stream Mapping (VSM), Total Productive Maintenance (TPM) and Standardized Work. Comparing the outcomes, the study found significant differences in the pre-test and post-test of each lean technique applied. VSM allows one to visualize and magnify the environmental performance of the process, which allows for simple quantifying of environmental metrics. TPM brings to light that equipment that is regularly maintained to operate at optimum condition reduces non-value adding energy usage. However, in contrast, Standardized Work has shown minimal benefits within the context of this research. The findings of this research are beneficial as they contribute to gaining a better understanding of the way lean tools affect environmental performance. While the study contributes to the current body of knowledge, it can also enlighten Small to Medium Enterprises, practitioners and larger organizations to rethink current strategy and allow for simultaneous implementation of Lean Green operations.

—In this paper, a conceptual framework to apply many techniques for implementing lean in the high-variety low-volume (HVLV) environment is presented. Lean production has increasingly being implemented as a potential solution for many organizations. Anyway, the lean formula is applicable directly only to the make-to-stock business, but the make-to-order (MTO) product environment has to adapt lean manufacturing principle. The method of this paper has a two-phase quantitative framework to transform small and medium enterprises (SMEs) to be lean. Phase 1 has three interrelated components: (1) re-engineering an organization by using the power of computer simulation combined with business process. (2) Value stream mapping (VSM) is used to create a map of both value and waste in a given process. This tool has also a main drawback for job shop facility because many value streams are composed of hundreds of industrial parts and products. (3) Integrative supplier relationship is one of the most critical factors to maintain an advantage in the increasing levels of competition. Phase 2 performs a just in time production schedule by using ant colony optimization technique combines with a simulation tool. The aims of this paper are to develop a suitable lean manufacturing system for SMEs and to study the performance of the system for improving effectiveness. The result shows how to combine lean concept with simulation optimization, the step of this framework to obtain the optimization solution.

Buildings are responsible for 40% of global energy use and produce over a third of global greenhouse gas emissions. These impacts are being acknowledged and addressed in specialist building design techniques and technologies that aim to reduce the environmental impacts of buildings. These techniques and technologies can be referred to collectively as green building technologies. This chapter describes green building technologies and shows why they are vital in addressing climate change and reducing the negative environmental impacts associated with built environments. A structured approach is presented which can be applied to identify and integrate green building technologies into new and existing buildings. By combining global implications with technical detail, the chapter provides a valuable guide to green building technologies and their role in supporting a transition to a more sustainable future.

The Relationship

Purpose – Industries differ in their environmental impacts, such as emissions, water and energy use, fuel consumption and hazardous wastes, which will have implications for how environmental performance translates to operating performance and market value at company level. By incorporating industry-specific differences of environmental impacts, this paper includes industry-level environmental risk as a moderating factor on the relationship between two indicators of corporate environmental performance (CEP) (management and policy) and corporate financial performance (profitability and market value). The paper aims to discuss these issues. Design/methodology/approach – Using panel data of US companies across all industries, the paper empirically tests a regression model, which includes an interaction effect representing both the form and strength of dependency of CEP on the environmental risk of the industry. The paper adopts the natural resource based theory to argue that financial returns are a decreasing function of CEP in high environmental impact industries, where environmental spending beyond compliance is costly and there is not much opportunity for consumer orientation. Findings – The results show that environmental management has different impacts on operating performance at high and low environmental risk of the industry (form of relationship) while environmental policy (reporting) has a stronger signal on market premium in industries with low rather than high environmental risk (strength of relationship). Differences in both form and strength of moderating effects are demonstrated. Research limitations/implications – Further research can introduce other industry-specific moderating factors, such as the disclosure maturity of the industry and the institutionalization of environmental disclosures across boarders in the industries, in order to explore the complexity of the relationship. Practical implications – The results of the paper are relevant to investors, company managers and a broad group of stakeholders when considering both industry- and company-level environmental risks. Originality/value – Previous studies have relied on controlling for industry membership. This paper uses an industry-specific environmental variable, environmental risk of the industry, to examine the form and strength of moderating effects.

Medium Enterprises

Micro, Small and Medium Enterprises (MSMEs) have been accepted as engines of economic growth to promote and accelerate equitable development worldwide. The major advantage of this sector is its enormous employment potential which constitutes around 90% at significantly low capital involvement. In recent years the sector has consistently registered higher growth rate as compared to the overall industrial sector. With its agility and dynamism, the sector has shown admirable innovativeness and adaptability to survive the recent economic downturn and recession. However, despite the significant contributions made towards various aspects of the nation’s socio-economic scenario, this sector too faces several critical issues that require immediate attention. One such factor that falls under this text is the prevalence of age old technologies across the sectors and inherent inefficiencies associated with resource and energy utilization. As a result of increasing awareness towards efficient usage of energy and other resources, there has been a visible reduction in energy intensity but still studies conducted on the MSME sector reveal that the energy intensity per unit of production is much higher than that of the organized large scale sector. Most foundry units which are highly energy intensive fall under MSME category in India. India produces 12.24% of global casting at present. If energy intensity per unit production of MSME is to be brought closer to that of organized large scale sectors then energy conservation is the only way that can do so with efficient use of energy and steep rejection of energy wastage without suppression of demand for energy use.

Lean manufacturing is one of the most popular improvement agents in the pursuit of perfection. However, in today’s complex and dynamic manufacturing environments, lean tools are facing an inevitable death. Industry 4.0 can be integrated with lean tools to avoid their end. Therefore, the primary purpose of this paper is to introduce an Industry 4.0-based lean framework called dynamic value stream mapping (DVSM) to digitalize lean manufacturing through the integration of lean tools and Industry 4.0 technologies. DVSM with its powerful features is proposed to be the smart IT platform that can sustain lean tools and keep them alive and effective. This paper specifically tackles the scheduling and dispatching in today’s lean manufacturing environments, where the aim of this research is developing a smart lean-based production scheduling and dispatching model to achieve the lean target through optimizing the flow along the VSM and minimizing the manufacturing lead time. The developed model, called the real-time scheduling and dispatching module (RT-SDM), runs on DVSM. The RT-SDM is represented through a mathematical model using mixed integer programming. Part of the testing and verification process, a simplified IT-based software, has been developed and applied on a smart factory lab.
