The document discusses green manufacturing. It defines green manufacturing as implementing processes that reduce energy and resource consumption, waste, and water usage. It explains that green manufacturing aims to minimize the environmental impact of manufacturing through using renewable energy sources, reducing pollution and emissions, recycling and reusing materials. The document outlines the need for green manufacturing due to issues like climate change, depletion of natural resources, and waste generation. It presents examples of companies like Tesla and Nike that have implemented green energy, green processes, and green products into their manufacturing.

2. What is Green Manufacturing?
2
Implementing any kind of substitution in the manufacturing
process which leads to a reduction in energy consumption,
resource consumption, waste by-products and water usage
Green manufacturing is the renewal of production processes and
the establishment of environmentally-friendly operations within
the manufacturing field.
“Greening” of manufacturing
 Natural resources
 Reduce Pollution and waste
 Recycle and Reuse materials
 Harmful Emissions

3. What ‘Green’ means?
3
• Green stands for ecological sustainability and encompasses many different
concerns including, but not limited to, air, water and land pollution, energy
usage and efficiency, and waste generation and recycling
• Green initiatives aim to minimize the impact of human activities on the
environment

4. Need for “Green”
Emissions and
associated climate
change
•Accelerating Greenhouse gas emissions
•At the current rate, emissions will double by 2050, compared to the
2000 levels, a corresponding temperature rise of 4–6°C over pre-
industrial levels by the end of this century
Fast depletion of
scarce natural
resources
•With ever increasing population and industrialization, the
consumption of natural resources is rapidly on the rise, while their
availability is shrinking
•Periodic mismatches in demand-supply and highly fluctuating prices
Growing waste
generation and
pollution
•Increased industrialization have led to significant growth in waste
generation and environmental pollution
•Industrial waste with chemical composition can be potentially
dangerous to health, and its disposal without treatment is leading to
land and water pollution.

Transformation to Green Manufacturing
6
Green initiatives in the power sector have the maximum impact on reducing CO2
emissions followed by transportation and then the industrial sector
Green manufacturing involves transformation of industrial operations in three ways

7. 7
• Green energy comes from natural sources like wind, water, and sunlight
• Can be produced with little pollution, it’s far more environmentally-friendly than
other types of energy
• Does not contribute to climate change or global warming like traditional energy
sources
Green Energy

8. • Inexhaustible source of energy
• Reduce Energy-Related Costs
• Attract New Customers and Increase Sales
• Tax Incentives
• Boost Workforce Morale and Innovations
• Societal Impact

Benefits of Green Energy

9. 9
• The entire plant will run on renewable energy
from solar panels, a nearby wind farm, and
a geothermal electricity plant
• All electrical outlets will connect to the wind
farm to provide the building with energy along
with the geothermal plant
• With the reduced cost of operating the
manufacturing plant, Tesla plans to sell its car
battery packs for $3,000 less than the current
going rate.

10. • Seek to minimize the impact of the manufacturing process on the environment at
every stage
10
Goals Minimize emissions, effluents, and accidents
Minimize the use of virgin materials and
non-renewable forms of energy
Minimize the life-cycle cost of products or
services
Green Manufacturing Process

11. 11
• “Linear” economy is based on
large quantities of cheap, easily
available energy, water and
materials.
• Rapidly reading its limits as
materials, water and energy
become more inaccessible or, at
least, costly to obtain.
• take + process + make + distribute
+ and dispose
Traditional Product Life Cycle

12. Green Product Life Cycle
12
• Circular economy is
restorative in nature and
“regenerative by design”
• Maintains products,
components, and materials at
their highest utility and value
at all times - minimize down
cycling or conversion to
energy or disposal.

13. Circularity vs Linearity
13
Circular economy is in the context of
the return loop - including extended
use of the product, return to
consumer via secondary use, repair,
remanufacturing or, at least,
resource recovery.

Directions for circular model design

15. 15
• Reduce your waste: Monitor your inventory supply and look for ways to improve
your process
• Reuse what you can
• Recycle
Reduce Reuse Recycle

16. 16
Green Products
• Energy efficient, durable and often have low maintenance requirements.
• Free of Ozone depleting chemicals and don’t produce toxic by-products
• Often made of recycled materials or content or from renewable and sustainable
sources.
• Biodegradable or easily reused either in part or as a whole

17. Environmental Product Declaration
Depends on
• Material content
• Recycled content
• Service life
• Global warming potential
• Water consumption
• Emissions to air and water
• Waste generation
• Ozone depletion potential
• Respiratory effects
Knowing this information makes it possible for any interested party to determine
the environmental impact of any product or assembled group of products

• Diverted more than two billion plastic
bottles from landfills into recycled
polyester — enough to cover about 3,500
football pitches
• By using recycled polyester Nike is also
reducing the energy consumed in the
manufacturing process by up to 30
percent compared to virgin polyester.
