The document provides an overview of hazardous wastes and their management. It discusses several key points:
1) Hazardous waste generation has become an international problem as industrialization has increased, with developing countries like India facing growing challenges in disposal.
2) Several landmark pollution episodes involving chemicals like DDT, mercury, and PCBs highlighted the health and environmental risks of hazardous wastes.
3) Hazardous wastes are defined based on their potential to harm human health or the environment. India generates around 7 million tons annually, with most disposed in landfills.
4) Major industrial sources of hazardous wastes include chemicals, metals, and other sectors. Rules and regulations aim to ensure
After China, India is the largest populous country in world it share 16% of world population and 2.5% of world’s land. Rapid industrialization last few decades have led to the depletion of pollution of precious natural resources in India depletes and pollutes resources continuously. Further the rapid industrial developments have, also, led to the generation of huge quantities of hazardous wastes, which have further aggravated the environmental problems in the country by depleting and polluting natural resources. Therefore, rational and sustainable utilization of natural resources and its protection from toxic releases is vital for sustainable socio-economic development.

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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

INTRODUCTION
While there is little doubt that humankind’s increasing of natural law has
brought us increased life expectancy and higher quality of life for more people
than ever known before.
This has brought the risk of global calamity and impairment of human health.
Hazardous waste management has become an international problem
The environmental and Human Health consequences of the residuals and
wastes: not understood and recognised
Developments in science, epidemiology, toxicology and analytical chemistry
enabled to recognise
LAND Mark Episodes
DDT : Residues in deep sea liquid, Antarctic penguins, and the fatty tissues of
Homo sapiens. High levels of DDT in aquatic birds
Mercury : As liquid mercury to cure constipation.
Mercury salts: results in neurological disorder Dutch Hat industry
Organic form Methyl Mercury: More Pernicious Minamata Japan episode

2. HAZARDOUS WASTE ?
A solid waste or combination of solid wastes that,
because of quantity, concentration or physical,
chemical or infectious characteristics, may cause or
significantly contribute to an increase in mortality or
an increase in serious, irreversible, or incapacitating
reversible illness or pose a substantial hazard to
human health or the environment when improperly
treated, stored, transported, disposed, or otherwise
managed. About 290 million tons of hazardous
wastes are generated in the U.S. each year. About
4% is recycled. The rest is treated, stored or
disposed.
Generally the term hazardous waste means a solid waste, or combination of solid
waste that, because of its quantity, concentration, or physical, chemical or infectious
characteristics may:
Cause or significantly contribute to an increase in mortality or an increase in
serious irreversible, or incapacitating reversible, illness; or
Pose a substantial present or potential hazard to human health or the
environment when improperly treated, stored, transported, or disposed of, or
otherwise managed.
Hazardous wastes come in many forms. They can be liquid, solids, semisolid, or
contained gases. They can be manufacturing process byproducts, sludges or spent
materials or simply discarded products.
Hazardous waste can be classify on the basis of
18
Physico-chemical properties
Toxicological properties
Environmental properties
Specific effects on human health
EPA lists wastes based on three categories:
Exhibits a hazardous characteristic
Ignitibility, Reactivity, Corrosivity, Toxicity

CLASSIFICATION OF HAZARDOUS WASTE
On the basis of various properties of the waste can be classified under the following
categories:-
Explosive, Corrosive, Oxidizing , Flammable , Infectious , Irritant, Toxic,
Toxic for reproduction, Harmful, Mutagenic, Exotoxic, Carcinogenic,
Residuary hazardous property
GENERATION OF HAZARDOUS WASTE
Sources of hazardous waste in the country include those from industrial
processes, mining extraction, tailings from pesticide based agricultural
practices, etc.
Industrial operations generate considerable quantities of hazardous waste and
in rapidly industrializing countries such as India the contribution to hazardous
waste from industries is largest. Since industrial units are spread all over the
country, the impacts are region-wide.
States such as Gujarat, Maharashtra, TamilNadu, and Andhra Pradesh, which
and have undergone relatively greater industrial expansion, face problems of
toxic and hazardous waste disposal far more acutely than less developed
states.

10. BASEL CONVENTION ON THE CONTROL OF TRANSBOUNDARY
MOVEMENT OF HAZARDOUS WASTE AND THEIR DISPOSAL
The convention is ratified by 35 countries, it entered into force on 5th May, 1992. The
main principle of the convention is to regulate the Transboundary movement of
hazardous wastes with prior informed consent of the importing country and to ensure
environmentally sound management of hazardous wastes. The convention seeks to
prohibited the export of hazardous wastes without the consent of the importing
country.
26
Basel Convention
Basel convention is an international environment agreement on “control of
trans boundary movement and disposal of hazardous waste” which was
drafed on 22nd March, 1989.
Basel BAN
On 31st Dec, 1997 a “total ban” on the trans boundary movement was
decided rather than “control” or the “partial transboundary movement” of
hazardous waste from OECD (Organisation for Economic Corporation and
Development) to non OECD.
GLOBAL SCENARIO
Large manufacturing industries like chemical, metal, electrical, petroleum,
transportation etc., generate hazardous wastes at the rate of more than 1000
kg/month/unit.
More than 80% of the world's hazardous waste is produced in the United
States and other industrial countries.
300-500 million tons of heavy metals, solvents, toxic sludge, and other wastes
accumulate every year from industry.
In developing countries, 70% of industrial wastes are dumped untreated into
waters where they pollute the usable water supply.
INDIAN SCENARIO
India has grown as 2nd fastest growing economy. It accounts for 20% of Asian
and 10% of global growth.
At the same time it is producing around 7.2 mt of hazardous waste out of
which, 1.4 mt are recyclable, 0.1 mt to be incinerated and 5.2 mt to be
disposed on land.
Country constitutes of :
Global population 16%
Global land mass 2.4%
Population growth 1.6%
Polluted surface water 70%
Diseases due to water 70%

wastes display on-line data outside the factory gate, on quantity and nature of
hazardous chemicals being used in the plant, as well as water and air emissions and
solid wastes generated within the factory premises. If such data is not made available,
the unit should be asked to show cause or even be asked to close down”.
National Policy Document to be made by the MoEF / CPCB:
“The policy document should emphasis a commitment to the recycling of wastes and
materials, and propose incentives for encouraging and supporting recycling. Industries
must be given a clear message that they must show tangible and concrete results as for
as prevention and reduction of wastes are concerned. If they do not, they should be
made to pay a waste regeneration tax------”

15. CONCULSIONS
The very real problem that hazardous waste has created and is creating is
compounded by the commingling of technological obstacles; limited financial
resources, a general with an inadequate understanding of basic scientific concepts
including risk analysis.
However, there has been continuous reduction in hazardous waste generation due to
regulatory enforcement, legal liability, exposure to public scrutiny, reputation and
image impacts
With Source reduction cleaner and greener production, material substitution a, reuse,
etc we can have sustainable development and we can all look forward to leaving a
smaller footprint for future generations.
While we are still in the process of effective implementation of the regulations
through creating awareness among the people especially among the waste generators
a move towards “Prevention is better than cure” by adopting waste minimization
technologies and management of the unavoidable waste in the environmentally sound
manner is the NEED OF THE HOUR
“Nature is essence of civilisation, to preserve it in its pristine glory
and magnificence becomes our priority”
