Abstract:

As we enter the 21st century, humanity faces enormous challenges in the sustainability of our 

current lifestyles and systems. There are a number of critical global environmental issues

including energy, pollution, transportation, agriculture, land use, construction, water access

and use, and ecological destruction. Green manufacturing is a subset of green engineering.

Environmentally friendly machining is a part of green manufacturing. It is included in the

concept of sustainable manufacturing, which considers economical and social concerns in

addition to environmental concerns.

Introduction:

"ver a decade, there has been a renewed focus on the impact of organi%ations and

manufacturing on the natural environment. Increasingly, sta&eholders including regulators,

customers, shareholders, board members, and employees are as&ing or re'uiring

organi%ations to be more environmentally responsible with respect to their products and

 processes. (esearch on the impact of environmental practices on organi%ational outcomes is

somewhat inconclusive. !ome researchers have found that environmental initiatives may

have a negative impact on company performance. Every day, engineers and scientists ma&e

technical decisions which have significant impact on the environment. These decisions can

either move us in the direction of sustainability or contribute to the growing problems.

What is Sustainable Manufacturing?

(ecently, the &eyword )sustainable manufacturing* has become very popular. !ustainable

manufacturing considers environmental, economic, and social aspects. The aim of the

sustainable manufacturing is to develop technologies for transforming materials withob+ectives of reducing emission of greenhouse gases, avoiding use of non renewable or toic

materials, and avoiding generation of waste.

In a &eynote paper, -est&amper et al. 2$$$/ have listed the following five critical

factors that the world is confronting0

1. A rising consumption of natural resources

2. The dramatic increase in world population

. Environmental impacts, i.e., limited natural resources energy, materials/

#. Global communication networ&s based on standards

. An unstoppable worldwide globali%ation

To overcome these factors, there is a need to switch over to sustainable manufacturing. The

term sustainability is often used to cover environmental issues. As a result of the 34 General

Assembly resolutions, the -orld 5ommission on Environment and 6evelopment was set up.

The commission published a report entitled )"ur 5ommon 7uture,* which is commonly

&nown as 8rundtland report.
