3. INTRODUCTION:
 Glass is a sustainable, fully recyclable material which provides great environmental benefits such as
contributing to mitigating climate change and saving precious natural resources.
 It is also highly appreciated in many applications for its inert nature and its contributions to
safeguarding people’s health ad well being.
 Per capita glass consumption has increased significantly in India from 0.58 kg to 1.1 kg
 The glass consumption growth is expected in construction (10-12%), automotive (20), consumer
goods (15-20) and pharmaceuticals (15-18) sectors.

4. Safety issues in glass industry
It is very important for the glass industry to take into account the workplace related safety
measures of employees.
Pilkington India
Health & Safety Management System:
 believe that all accidents are preventable
 developed training programs and safety
education, and they carefully monitor the
safety statistics
 Safety performance is measured using two
key performance indicators. The Lost Time
Injury Rate (LTIR) keeps a record of the work-
related accidents or illnesses.
NSG Group
Health and Safety:
Emphasis lies on the importance of individuals and taking personal responsibility
for an appropriate safe behaviour, along with managers showing commitment and
taking the lead to key safety leadership behaviour
Safety organization and strategy
• The Sustainability Director of NSG Group reports to its Chief Operating Officer
and provides him the monthly safety updates.
• The Group follows a focus site approach that provides an additional support and
frequent regular reviews for sites that likely to have significant injuries.
Moving safety to the next level
• Conduct independent audits of safety tool
• Keep improving the level of proactive employee involvement
• To improve its overall level of the safety leadership, further development its first-
line supervisors are focused
NSG Safety Day: 15 October 2015

5. Use of cullet in glass manufacturing
By maximizing the amount of recycled glass in the production process, companies today are reducing their
environmental impact.
Cullet: Scraps of broken or waste glass gathered for remelting, especially with new material.
Benefits of using cullet in glass manufacturing
Energy Savings
Potential
As a general rule, every 10 % of extra cullet results in a 2.5 – 3.0 % reduction in furnace energy
consumption. Energy savings are estimated at around 8 MJ for every percent increase (by weight) in
cullet use
CO2 Emission
Reduction
Potential
Reduced CO2 emissions are brought about by:
(a) A reduction in fuel consumption; and
(b) Reduced usage of soda ash, limestone and dolomite, which are all carbonates giving off carbon
dioxide when melted.
Costs The use of cullet generally results in significant cost savings as a result of the reduction in both energy
and raw material requirements.
Each tonne of cullet used, saves around 1.2 tonnes of raw materials in the batch.

6. • U.S. Glass Recycling Coalition
• Primary goal is to make glass recycling a successful
industry
Glass Packaging Institute (GPI)
• Glass recycling rate in the EU had reached 73%.
• Advent of the circular economy phenomenon.
• Made Europe the continent with the highest glass
recycling rates in the world.
European Container Glass
Federation
• Used recycled glass in the manufacturing process
• Pursues a Zero-landfill status to be achieved by 2020
• In 2014, the Group’s overall recycling rate was 96.7%

7. Waste Heat Recovery System
Reasons to invest in Waste heat Recovery System

8. Waste Heat Recovery System
Reasons to invest in Waste heat Recovery System
Savings:-
 Reduction of energy
consumption costs
 Fast amortization within a few
years
 No additional personal
required in control room
Safety of investment:-
 Less dependency on external
sources of energy
 Less dependency on constant
rising energy costs
 Installation without influence on
the production process
 Installation during line operation
in many cases
 Use of standard components
Environmental protection:-
 Improvement of environmental
protection
 Gain in green image

9. Waste Heat Recovery System
Applications of WHRS for Glass Industry:-
 Heating of the heavy fuel oil (in case of heavy fuel fire furnaces)
 Electric power generation by Steam Rankine Cycle
 Electric power generation by Organic Rankine Cycle
 Chilling/Refrigeration
 Wastewater recycling
 Combination of all above
Siemens follows a system of highly advanced energy recovery with reliable control technology.
The company supplied automation technology for the plant and the turbines for energy recovery.
Osterweddingen is one of the first glass plants in the world to recover a large part of the process waste heat using a
modern heat recovery system.

10. Ethical issues in Glass Industry
 Glass industry in India especially Glass Bangle industry suffers from problem of Child Labor.
 This problem can be especially seen in Firozabad and Agra districts of Uttar Pradesh.
 Glass and Bangle industry of Firozabad employs more than 500,000 men, women and children. Large percentage of this
workforce is children.
 But situation is changing now.
 Many NGOs are creating awareness about this situation in Firozabad.
 Government has also become serious after media hue and cry.
 Recently, Rajya Sabha passed amendments to Child Labur act , which paves a way for complete prohibition of
employment of children below 14 years of age.
 Awareness about the bad condition of child laborers in glass bangle industry among consumers, has also forced
manufacturers to desist from employing children as laborers in their factories.

11.  Glass generates minimal environmental impact
 Transformative and disruptive advancements in operations
 Owen-Illiois aims
 to reduce
 energy consumption by 50%.
 total CO2 equivalent emissions by 65%.
 to increase the usage of cullet globally to 60%.
 Integral in designing truly sustainable and low energy buildings
