**Abstract**

The manufacturing SMEs are facing the burden of non-equilibrium of the supply–demand chain along with the global change in the climate. Several SMEs are looking for a substitute that can create a balance between performance and the environment. In spite of numerous studies related to green and lean that has been evolved, none of them is able to clearly define the spheres of green and lean. Here in this chapter, there is an exploration of advancement of lean and green manufacturing and its impact on other sectors. It also highlights the methodology adopted in implementing the same. This chapter recognizes the commonalities between lean and green approaches, the collaboration and impact, techniques involved. Also, the impediments and perplexities confronted by the manufacturing sector are examined. Further, this gives a better understanding of the challenges before implementing lean with green. This chapter also recognizes possible gaps in the literature that will help to eliminate the barrier toward this Neo manufacturing.

## **1. Introduction**

Liberalization Privatization Globalization (LPG) has created market possibilities for manufacturing businesses around the Globe. This encourages competition worldwide for quality products, thereby leading to different ways to enhance their competency. A global phenomenon like financial instability, political imbalance, technology revolution, stringent regulation and global climate changes are affecting the competition [1]. Both energy and resources cost are always escalating due to non-equilibrium between supply and demand this is effecting the operation cost and economics of manufacturing directly. One vital strategy for SMEs to face competition to diminish the waste of resources by inefficient operation and production methods.

Numerous big Industries have implemented the lean-to step up competition worldwide [1]. This idea of lean is exceptionally well known and embraced in numerous businesses including Toyota, Boeing and Ford. With numerous elucidations for defining lean that have come to perplexity to recognize its effect. The description of lean itself is tricky. Some expressed lean has philosophy than a plethora of tools. On the other side, a viable and system approach depicts lean is an assortment of waste diminishment approaches. Also lean is a framework with the primary objective to dispense waste. In any case, the common lean plan centres on the diminishment of waste. The lean tactics offer technique, tools, practices, and methodologies which can be useful to the manufacturing framework resulting in fewer resources utilization and fewer wastes. Lean manufacturing is actualized within manufacturing facilities since the effective usage by the Toyota Production System (TPS). Lean Manufacturing is characterized as an approach that disposes of all non-value added activities in production. Whereas lean centres the operational part, green looks into environmental perspective. Green addresses ecological balance and includes distinctive apprehensions like a waste, air, water and land pollution along with recycling management to enhance productivity [2]. The European Commission expressed the principles and practice of green in liaison with other buffer zones thus creating green economy which enhances the product value with lesser utilization of environmental-friendly resources everyplace conceivable. The green economy is an imperative way to propel financial development in the advancement of reducing carbon emission in process and products. From the green development point of view, the World Bank (2012) characterized green growth as a development effective in utilizing normal resources, limit contamination and natural impacts and resilient towards normal risks. Green development underscores worldwide maintainability that empowers the world's poorest and most powerless to take advantage of proficient, clean and buoyant progress. Green also additionally branded as the modern Lean wherein businesses have begun to provide support [3]. It is proved that green component primarily centres on cutting down contamination by increasing the value using resources judiciously [4, 5].

Green manufacturing has numerous acknowledgements in the literature study. Green Manufacturing is a trading technique that centres on productivity by the responsive and active environmentally friendly process. It is also seen as a rejuvenation of the manufacturing sector [6]. It alludes to any Manufacturing unit which employs innovation and renewable sources of energy whereas "Green" refers to activity to decrease contamination and waste by the reduction in the resource. The study reveals that industries that have implemented innovative green management, not only progress but also fulfil the requests of the buyer to enhance reputation among controllers and the public [7].

The collaboration within lean and green will encourage and improve performance by creating valuable products and waste diminishment. This combination has blended and intrigued many analysts. Numerous rudiments drive the accomplishment of Lean Green Manufacturing are examined within this chapter. Its usage is a major challenge due to the want of a Lean green domain expert, thereby deferring its execution and decrease in industry competitiveness. This chapter surveys standard of Lean Green manufacturing and its execution strategies. Also covers their metrics and determinants, challenges and future prospectus about Lean Green manufacturing.
