Review on Recent Trends of Zero Waste Management in Mechanical Fields

Abstract

Resources which exist in abundant in nature are being wasted have made the researchers to focus on the
reduction of waste. The word waste refers to unused products or inefficient or non- essential goods.Large amount of
waste are produced every day which not treated properly. Lean Manufacturing conveys waste as any activity that
consumes resources but adds no value. Wastes are classified into 1.Over production: Producing more than demand
2.Waiting: Long cycle time 3.Transport: Unnecessary movement 4.Over processing: Poor product design consumes more
process which adds no value 5.Excess inventory: poor planning 6.Unnecessary movement of workers 7.Defective
product.
Zero Waste is a philosophy that encourages the redesign of resource life cycles so that all products are reused. The goal
is for no trash to be sent to landfills or incinerators. Recycling and reuse can be eliminated by zero defects. Expenditures
for both producers and consumers can be reduced with the help of zero waste. ZWM can be achieved with the use of
Lean optimization tools and Sustainable manufacturing theories. The review discusses the current trends in forming,
foundry and machining areas. Many references were made on the properties and applications have been cited in this
review.
