What is green manufacturing ?
is about implementing any kind of substitution in the
manufacturing process which leads to a reduction in energy
consumption, resource consumption, waste by-products, and
The design, processing and commercial use of materials
processes and products, which are economical and
sustainable while minimizing pollution and risk to human
health and the environment.
Need of green manufacturing
Customers are environment conscious.
Environmental protection is a top agenda for everyone.
Reasons for environmental care
running out of fossil fuel supply (energy crisis) global
depletion of the ozone layer
loss of trees and forest
Green manufacturing is a challenge for today but as Business
opportunities for tomorrow
Green Manufacturing’s Goal
goal is to achieve sustainability.
Every company when it comes to green
manufacturing should be conserving natural
resources for future generations.

Benefits Of Green Manufacturing
a great reputation to the public
Saves useless cost.
Promotes Research and Design
E-waste treatment in guangdong ,China

Process of Green Manufacturing
Lead-Free Soldering for electronics
Reduce Emission of Pollutants
Use of environment-friendly chemicals
Use the lead-free solders to manufacture the products and don’t
allow any intentionally added Pb in the products, then the
products can be defined as lead-free products.
Packaging Materials – Disposal and Environment-friendly
No release of toxic substances in product life
End of Life Treatment – Recycling of Components, Collection of
Use of Biodegradable materials .
Different Aspects in green manufacturing

Example of Green Manufacturing
Ohio Manufacturing Company Wanted to
develop ways of reducing scrap metal.
Scrap metal was created because of the depth of the draw
on the metal sheets and since the machines created severe
deep draws it would tear and mar the metal sheets.
Murray Ohio Manufacturing Used a chlorinated oil with
an additive of graphite to create heightened lubricity.
Oil was used as a stamping lubricant
Looked at two different chemicals
*Dry Coating Product
Products of Murray Ohio
Fig no : 7
Required machinery needed 400ft in length.
Teflon coating that the product left made the sheets
Cost of machinery was high.
System was 10ft in length.
Cost of machinery had a payback of six months.
Coldkote the winner
The benefits of Coldkote
scrap metal went from 9% to 1/10 of 1%.
Tool life increased 30-50%.
Polish time went from 3-4days to once a day.
Coldkote Green Manufacturing
removal of Coldkote was used with a warm alkaline bath.
Coldkote becomes a solid compound once its applied therefore
reducing the amount of spilling and dripping.
Non-oil lubricant reduces toxicity of company’s waste stream.
A warm alkaline bath eliminates the need for any hazardous
Decreased spilling and dripping allowed for cleaner facilities.
Green manufacturing is the elimination of waste through the
Companies must step up and take responsibility for their actions.
Green manufacturing promotes innovative design.
Processes such as JIT and zero emission should be exercised by
