With mounting concerns over the state of our planet, there is continuing demand that chemists
and chemical engineers should develop greener chemical processes and products. In the 1990s, with the
growing awareness of the hazardous impacts of the chemical industry, the green chemistry revolution was
launched by American chemists Paul T. Anastas and John Warner. Green chemistry is the kind of chemistry that
seeks to minimize pollution, conserve energy, and promote environmentally friendly production. This paper
provides a brief introduction to green chemistry.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. Green Chemistry is the
utilisation of a set of
principles that reduces
or eliminates the use or
generation of hazardous
substances
in
the
design, manufacture and
application of chemical
products .
5. Chemistry is undeniably a very prominent part
of our daily lives.
Chemical developments also bring new
environmental
problems
and
harmful
unexpected side effects, which result in the
need for ‘greener’ chemical products.
A famous example is the pesticide DDT.
6. Green
chemistry looks at pollution
prevention on the molecular scale and
is an extremely important area of
Chemistry due to the importance of
Chemistry in our world today and the
implications it can show on our
environment.
The
Green
Chemistry
program
supports the invention of more
environmentally
friendly
chemical
processes which reduce or even
eliminate the generation of hazardous
substances.
This program works very closely with
the twelve principles of Green
Chemistry.
7.
8. “It is better to prevent waste than to
treat or clean up waste after it is
formed”
9. » Atom Economy
Synthetic methods should be
designed
to
maximise
the
incorporation of all the materials
used in the process into the final
product.
» Less Hazardous Chemical Synthesis
Wherever practicable, synthetic
methods should be designed to use
and generate substances that
possess little or no toxicity to
people or the environment.
10. Designing Safer Chemicals
Chemical products should be designed
to effect their desired function while
minimising their toxicity.
Safer Solvents and Auxiliaries
The use of auxiliary substances (e.g.,
solvents or separation agents) should not
be made unnecessary whenever possible
and innocuous when used.
Design for Energy Efficiency
Energy requirements of chemical
processes should be recognised for their
environmental and economic impacts and
should
be
minimised.
If
possible,
synthetic methods should be conducted at
ambient temperature and pressure.
11.
Use of Renewable Feedstocks
A raw material or feedstock
should be renewable rather than
depleting whenever technically and
economically practicable.
Reduce Derivatives
Unnecessary derivatization (use of
blocking
groups,
protection/deprotection,
and
temporary
modification
of
physical/chemical
processes) should be minimised or
avoided if possible, because such
steps require additional reagents and
can generate waste.
Catalysis
Catalytic reagents (as selective as
possible)
are
superior
to
stoichiometric reagents.
12.
Design for Degradation
Chemical products should be designed
so that at the end of their function
they break down into innocuous
degradation products and do not
persist in the environment.
Real-time Analysis for Pollution
Prevention
Analytical methodologies need to be
further developed to allow for realtime, in-process monitoring and control
prior to the formation of hazardous
substances.
Inherently Safer Chemistry
for Accident Prevention
Substances and the form of a
substance used in a chemical process
should be chosen to minimise the
potential for chemical accidents,
including releases, explosions, and
fires.
13. The major uses of GREEN CHEMISTRY
Saving Energy
Minimum Global Changes
Minimize the Depletion
of Resources
Food Supply
Releasing Non-Toxic
in the Environment
13
14. 1.Saving Energy
Green Chemistry will be essential in
Developing the alternatives for energy
generation (photovoltaic's, hydrogen, fuel
cells, biogases fuels, etc.)
15. WHAT IS HYDROGEN ECONOMY ?
The hydrogen economy describes a
system in which our energy needs
are
predominantly
met
by
hydrogen, rather than fossil fuels.
This type of economy would rely on
renewable resources in the form of
hydrogen gas and water, drastically
changing pollution , electricity
sources, infrastructure, engines,
and international trade, without
impacting our quality of life. In a
hydrogen economy, vehicles like
cars
and
airplanes
use
hydrogen fuel
cells for
power,
rather than petroleum distillates.
16. USES OF HYDROGEN
Hydrogen is a very useful gas.
1) It is used as a fuel
2) It makes ammonia, NH4
3) It is used to make plastic (PV)
4) It also turns liquid vegetable
oils into margarine (vegetable
ghee)
Hydrogen Gas filling in Car
17. ADVANTAGES OF HYDROGEN
•Waste product of
burning H2 is water.
•Elimination of fossil fuel
pollution.
•Elimination of
greenhouse gases.
•Elimination of economic
dependence.
•Distributed production.
18. 2.Resource Depletion
Due
to the over
utilization of nonrenewable resources,
natural
resources
are being depleted
at an unsustainable
rate.
Fossil fuels are a
central issue.
19. Minimize the Depletion of Resources
Renewable
resources can be
made
increasingly
viable
technologically and economically
through green chemistry.
Biomass
Nano science & technology
Solar Energy
Carbon dioxide
Waste utilization
20. 3.Minimum Global Changes
Concerns for climate change, oceanic
temperature, stratospheric chemistry
and global distillation can be addressed
through
the
development
and
implementation of green chemistry
technologies.
21. 4.Food Supply
While current food levels are sufficient, but the
distribution is inadequate
Agricultural methods are unsustainable
Future food production intensity is needed.
Green chemistry can address many
food supply
issues
22. Green
developing:
Pesticides
chemistry
is
which only affect
target organisms and degrade
to innocuous by-products.
Fertilizers
and
fertilizer
adjuvant that are designed to
minimize
usage
while
maximizing effectiveness.
Methods of using agricultural
wastes for beneficial and
profitable uses.
23. 5. Releasing Non-Toxics in the Environment
Substances
that
are
toxic to humans, the
biosphere and all that
sustains it, are currently
still being released at a
cost of life, health and
sustainability.
One
of
green
chemistry’s
greatest
strengths is the ability
to design for reduced
hazard.
24. Business benefits of green chemistry
include: improved resource efficiency
and lower raw material and utility bills
Reduced waste treatment and disposal
costs.
Ability
to
capitalize
on
the
environmental technology marketplace
by designing new, 'greener' products
Improved health and safety for staff
and customers
Environmental benefits include: fewer
raw materials and natural resources
used.
Lower levels of chemicals released to
the environment
Cleaner production technologies
Reduced emissions and product impacts
25.
26. DRY CLEANING OF CLOTHES
Tetra
chloroethene(C2Cl2) was earlier
used as solvent for dry cleaning but these
compound contaminates the ground water
and suspected carcinogen.
The process using this compound is now
being replaced by a process where
liquefied carbon dioxide with a suitable
detergent is used .
Replacement of halogenated solvent by
liquid Carbon dioxide (CO2) will result in
less harm to ground water .
27. BLEACHING OF PAPER
Chlorine
gas was used
earlier for bleaching of
paper .
These
days
hydrogen
peroxide
with
suitable
catalyst which promotes
the bleaching action of
hydrogen peroxide is used .
28. SYNTHESIS OF CHEMICALS
Ethanal (CH3CHO) is now
commercially prepared by one
step oxidation of Ethene in
the presence of ionic catlyst
in aqueous medium with a
yield of 90%
