Seven Billion Dreams. One Planet. Consume with Care.





The well-being of humanity, the environment, and the functioning of the economy, ultimately depend upon the responsible management of the planet’s natural resources. Evidence is building that people are consuming far more natural resources than what the planet can sustainably provide.
Many of the Earth’s ecosystems are nearing critical tipping points of depletion or irreversible change, pushed by high population growth and economic development. By 2050, if current consumption and production patterns remain the same and with a rising population expected to reach 9.6 billion, we will need three planets to sustain our ways of living and consumption.
The WED theme this year is therefore "Seven Billion Dreams. One Planet. Consume with Care." Living within planetary boundaries is the most promising strategy for ensuring a healthy future. Human prosperity need not cost the earth. Living sustainably is about doing more and better with less. It is about knowing that rising rates of natural resource use and the environmental impacts that occur are not a necessary by-product of economic growth.

Environmental Problems

Our environment is constantly changing. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing.
Global warming has become an undisputed fact about our current livelihoods; our planet is warming up and we are definitely part of the problem. However, this isn’t the only environmental problem that we should be concerned about. All across the world, people are facing a wealth of new and challenging environmental problems every day. Some of them are small and only affect a few ecosystems, but others are drastically changing the landscape of what we already know.
Our planet is poised at the brink of a severe environmental crisis. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. We are in a state of planetary emergency, with environmental problems piling up high around us. Unless we address the various issues prudently and seriously we are surely doomed for disaster. Current environmental problems require urgent attention.

15 Major Current Environmental Problems

1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.

5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.

6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.

8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial purpose.
9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.

11. Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known  environmental problem that can have serious effect on human health, wildlife and aquatic species.
12. Water Pollution: Clean drinking water is becoming a rare commodity. Water is becoming an economic and political issue as the human population fights for this resource. One of the options suggested is using the process of desalinization. Industrial development is filling our rivers seas and oceans with toxic pollutants which are a major threat to human health.
13. Urban Sprawl: Urban sprawl refers to migration of population from high density urban areas to low density rural areas which results in spreading of city over more and more rural land. Urban sprawl results in land degradation, increased traffic, environmental issues and health issues. The ever growing demand of land displaces natural environment consisting of flora and fauna instead of being replaced.
14: Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-vascular problems. High temperatures encourage the spread of infectious diseases like Dengue.
15. Genetic Engineering: Genetic modification of food using biotechnology is called genetic engineering. Genetic modification of food results in increased toxins and diseases as genes from an allergic plant can transfer to target plant. Genetically modified crops can cause serious environmental problems as an engineered gene may prove toxic to wildlife. Another drawback is that increased use of toxins to make insect resistant plant can cause resultant organisms to become resistant to antibiotics.

SUMMARY OF GLOBAL PROBLEMS AND CRISES

Note:  All these crises are interdependent and interrelated.  One crisis cannot be dealt with without dealing with them all.  Yet the last crisis (no global planning or regulation for the future) shows that the present institutions of the world (global capitalism -- as it exists today -- and the nation-state system) are incapable of saving the planet for future generations or even ensuring human survival.  This is why we need non-military democratic world government under the Constitution for the Federation of Earth.


A. The global environmental crisis Multiple forms of destruction leading to a possible collapse of the planetary ecosystem that supports life through global warming and other massive disruptions.

             1) Global destruction of forests and phytoplankton in the oceans (these capture carbon dioxide - 59% land, 41% oceans – hold moisture and soil, preserve species, moderate the environment and give off oxygen).
             2) World wide soil erosion and desertification (the world has lost 1/5 of its arable land in the last decade). Causes:  raising beef, lumbering, use of word for fuel, clear cutting for crops or profit).
             3) Worldwide burning of fossil fuels, primarily oil and coal, and burning of wood in the third world.
             4) Harming of forests, lakes, and their ecosystems by acid rain (including Alaska, Canada, Norway, Eastern U.S., Germany, etc.)
             5) Proliferation of nuclear waste hazards, and massive amounts of other toxic waste.
             6) World wide shrinking of fresh water supplied through pollution and diminishing aquifers.
             7) Spreading ozone holes resulting from long lasting chlorofluorocarbon gases.
             8) Massive extinction of species worldwide connected with the above factors.
             9)  Flooding of coastal areas world-wide as the ocean levels rise: displacing hundreds of millions of people and burying a large portion of the world's prime agricultural lands.

B. Global militarism and wars Extremely destructive of the environment, human rights, causing massive refugee problems, destruction of cultures, and civilized living for millions.

            1) Spread of nuclear and hi-tech weapons; wars and threat of wars in many places.
            2) Close to one trillion U.S. dollars per year and immense human resources wasted world-wide.
            3) World-wide sales of "conventional weapons" breeding conflicts, terrorism, dictatorships, and wars.
            4) International instability, danger of nuclear, chemical, or biological weapons.
            5) Global destruction of the environment through both massive military production and wars.

C. The population explosionSome scientists predict 9 - 10 billion people by the year 2025.

            1) In 1900, the earth had 1 billion people, in 1950, 2 billion, in 1990, 5.2 billion, today: over 7 billion.
             2)  80 million new people added to the population of the Earth every year.
             3)  Every person alive impacts the worlds resources and environment – first world people use 10-20 times more resources than third world people.
             4) Massive migrations, starvations, wars, refugees, and economic chaos result from overpopulation.
             5) Malnutrition and hunger in children leads to physically stunted and retarded human beings.

D. Global poverty and miseryCurrently U.N. figures estimate 1.5 billion persons or 20% of the earth’s population are living in "absolute poverty," with hunger, malnutrition, and no hope.

            1) Most of the world’s population lives in the global south while 6-10 % of the world population live in the "first world" countries leading to global conflict between rich and poor.
            2) Massive international debt of the poor countries to first world lending institutions.
            3) Social and economic chaos in "third world" countries and exploitation by first world countries and their corporations.

E. Global human rights abusesworld wide use of political murder, torture, massacres, brutality, disappearances, death squads, and dictatorships.

            1) This contributes to ethnic, religious, political intolerance, hatred, refugees, wars, and oppression.
            2) No global means of safeguarding democracy, cultural diversity, or human rights.
            3) No global means of educating people to live in an interdependent world, with social responsibility.
            4) No global means of protecting human rights or achieving equal opportunity for all.

F. No global regulation or planning regarding the futureglobal competition between nations and huge corporations for resources, military advantage, cheap labor, and avoiding environmental regulation.

               1) Systematic economic and military domination of the third world by the first world.
            2) Domination of the U.N. by first world nations. The U.N. impotent to address any of the above crises.
            3) Global competition among corporations and nations for resources, ascendancy, and profits.
            4)  The result is an utterly unsustainable world, heading toward ever greater cataclysms and disasters, unable to solve any of the above global crises, and living at the expense of future generations.
            5)  What group can possibility accomplish global regulation or planning for the future?   Only democratic world government under the Constitution for the Federation of Earth.

Water Crisis


Ensuring Clean Drinking Water
– A Global Challenge
It’s a growing global crisis, and it’s getting worse every day: more than one billion people on our planet lack access to fresh drinking water. Almost half of them are children — and 125 million of them are under the age of 5. If present global water consumption patterns continue, two out of every three people on Earth will suffer from water-stressed conditions by the year 2025.
Ongoing pollution, industrialization, deforestation, wasteful agricultural practices, global climate change and other environmental pressures are shrinking the planet’s clean water supply. Around the world, more people and communities are searching for clean, safe drinking water than ever before. And many of them are searching in vain.
Each year 3.5 million people die from water-related diseases. Each and every day, more than 4,000 children die of water-borne illnesses, which are now the second leading cause of death for children under the age of 5. Compounding these staggering numbers are the unpredictable effects of increasingly frequent natural and man-made environmental disasters. These devastating events render safe water undrinkable in a matter of hours or even minutes.
 
Addressing the Problem
– Reversing the Cycle
Bringing safe, clean drinking water close to people’s homes and to victims of disaster — in short, to anywhere it is needed around the world — is the key to reversing the endless cycle of misery that affects so many people. Making clean water accessible is the key to transforming communities and preventing large-scale catastrophes.
The mobile purification units World Solutions provides to those in need have been designed for both immediate use and ongoing service. Simple to operate and very reliable, they require little maintenance. Yet they can provide a continuous supply of safe drinking water within minutes of arrival. Their versatile, self-sustaining design functions reliably and repeatedly in the most difficult water conditions in both remote and urban locations. These innovative and highly effective mobile purification systems can be moved among multiple sites to provide drinking water to several areas.

Feed Water Treatment - Avoiding Corrosion

Feed Water Treatment - Avoiding Corrosion

The make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems

Corrosion is a major problem in steam systems with high consumption of make-up water. Fresh water contains dissolved oxygen. Oxygen together with the high temperature is highly corrosive for the carbon steel piping used in steam systems.
To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger chemicals and/or deaeration towers.

Scavenger Chemicals

Some commonly used scavenger chemicals are
  • Sodium Sulfite - common in low and medium pressure systems
  • Hydrazine - common in high pressure systems
  • Sodium erythorbate

Sodium Sulfite

Sodium Sulfite is a white crystalline or powder soluble in water. Sodium Sulfite decomposes on heating and is prepared from sulfur dioxide and sodium carbonate or caustic soda.
Sodium Sulfite is an effective scavenger for use in systems operating below 1,000 psi. For pressures above 1,000 psi breakdowns may form corrosive Hydrogen Sulfide and/or Sulfur Dioxide. Sodium Sulfite may also increase the amount of dissolved solids and the conductivity of the boiler water.

Hydrazine

Hydrazine efficiently eliminates the residual oxygen by reacting with the oxygen forming water and gaseous nitrogen.
Since hydrazine is a toxic chemical it must not be used in steam plants supporting food processing systems

Sodium Erythorbate

Erythorbic acid and its sodium salt can replace Sodium sulfite and Hydrazine as oxygen scavengers. Sodium Erythorbate is a non toxic oxygen scavenger that can be used also in food processing systems.

Adding Scavenger Chemicals

For best performance the chemical should be added in a storage tank before the feed tank. The efficiency of a scavenger is increased with longer reaction time. Adding to the make-up directly to the make-up water feed line is not recommended due to the short reaction time.

Deareation Tower

The make-up water should always be fed to the feed tank through a deareation tower on the top of the tank. The high temperature in the tank will reduce the ability of water to keep oxygen (and gases in general) dissolved. The oxygen will be forced out of the water and vented away from the system.

Supercritical Units, Power Plants

Condensate Polishing is an important aspect to power plant chemistry control of contaminants that can lead to corrosion and deposition in downstream components. For supercritical power plants polishing is absolutely a critical component to ensure the integrity of steam turbines.
A modern power plant that employ condensate polishing has ferrous metallurgy benefits from the presence of oxygen in the feedwater. The corrosion rate of carbon steel is dramatically reduced when operating with a positive potential (dissolved oxygen > ~50 ppb) versus what can be obtained with fully dearated water.
Provided the feedwater is relatively contaminant free the oxide formed when oxygen is present (>50 ppb) is several orders of magnitude less soluble than the oxide formed under dearated, reducing conditions. Modern once-through supercritical units operates under an oxidizing treatment without the addition of an oxygen scavenger and in most cases with the addition of oxygen to the feedwater. During operation these units either operate with their deaerator vents closed or equipped with oxygen feeders at the deaerator outlets.

Types of Corrosion

$

Types of Corrosion

Uniform, pitting, galvanic, crevice, concentration cell and graphitic corrosion

Corrosion can be categorized in some common types
  • uniform corrosion
  • pitting corrosion
  • galvanic corrosion
  • crevice corrosion
  • concentration cell corrosion
  • graphitic corrosion

Uniform or General Corrosion

The metal loss is uniform from the surface.
Often combined with high-velocity fluid erosion, with or without abrasives.

Pitting Corrosion

The metal loss is randomly located on the metal surface.
Often combined with stagnant fluid or in areas with low fluid velocity.

Galvanic Corrosion

Occurs when two metals with different electrode potential is connected in a corrosive electrolytic environment.
The anodic metal develops deep pits and groves in the surface.

Crevice Corrosion

Occurs at places with gaskets, bolts and lap joints where crevice exists.
Crevice corrosion creates pits similar to pitting corrosion.

Concentration Cell Corrosion

Occurs where the surface is exposed to an electrolytic environment where the concentration of the corrosive fluid or the dissolved oxygen varies.
Often combined with stagnant fluid or in areas with low fluid velocity.

Graphitic Corrosion

Cast iron loosing iron in salt water or acids.
Leaves the graphite in place, resulting in a soft weak metal.


Metals and Corrosion Resistance

Common metals and their corrosion resistance to aggressive fluids as acids, bases and more

A major problem in the process industry is the corrosion of metals in pipes, valves and other parts of the constructions. This guide indicates acceptable combinations of more or less aggressive fluids and commonly used materials.
Note! Remember that corrosion is a complicated issue, depending on the combinations of materials and the fluids, the fluid temperatures, the surrounding environment and the galvanic currents in the constructions. The table below must be used with care. Always check with the producer of the material.

A step towards sustainability - converting Waste to Energy
Giving a fillip to Swachh Bharat Mission conceived by Hon'ble Prime Minister Narendra Modi, our government has chalked out a plan to convert municipal solid waste (MSW) into energy.
For this, we will promote MSW to Energy in Andhra Pradesh by setting up such projects for an aggregate capacity of 130 MW at locations identified by our MA & UD department.
We will select the project developers for the identified locations through a Swiss Challenge (competitive bidding) process. One such plant will be set up in each district.
Recently, I visited the Timparpur Okhla Waste to Energy plant in New Delhi operated on a PPP basis by Jindal Group. This 18-MW project processes 2,000 – 2,500 tonnes of garbage per day and sells 50% energy generated to BRPL (BSES Rajdhani Power Limited) and balance in open market.
Currently, the installed capacity of Solid Waste to Energy projects in Andhra Pradesh is only 6 MW as against the estimated potential of 140-160 MW and are currently non-functional. A 1-MW plant requires around 50-60 tonnes of MSW daily.
Some of the technologies to convert MSW to Energy are Thermal conversion, Thermochemical conversion, Biochemical conversion and Electro chemical conversion.
Countries like China, Japan, Singapore, USA have recognised the importance of MSW to energy projects and have set up projects like Beijing Gaontun project (30 MW), Nakata Waste Management project, Keppel Tuas (22 MW), Covanta Lee County project (18 MW), respectively.
The reason why we are considering Waste to Energy Projects are:
a. Emphasis of National Action Plan on Climate Change (NACPP) on MSW processing
b. Emphasis given by The Electricity Act, 2003 and National Tariff Policy, 2006 on promotion of MSW to Energy projects
c. Twin benefits from MSW to energy projects of MSW disposal and Electricity generation (thereby reducing dependence on coal and gas as fuel)
In Andhra Pradesh, nearly 8,000 tonnes of MSW is generated every day but the disposal mechanism of this huge amount of MSW is not developed and faces numerous challenges.
To reap the dual benefits of converting waste to energy and by achieving objectives under the Swachh Andhra Mission, the government has embarked on a journey to make this fruitful.
I strongly believe that this is a step towards sustainability and sustainable living is the only way forward.

WHAT IS ENVIRONMENTAL COMPLIANCE AND ENFORCEMENT AUTHORITIES REQIRED TO CONTINUOUS AWARENESS

20 power plants directed to comply with environment standards

l   | Last Updated: 05 May 2015, 18:20
New Delhi: The Central Pollution Control Board ( CPCB) has not conducted any specific assessment of pollution caused by thermal power plants around their sites, but has so far asked 20 of them to comply with environment standards, Lok Sabha was informed on Wednesday.
Representational picture
Replying to a question in Lok Sabha, Environment Minister Prakash Javadekar said CPCB issued directions to the power plants on the basis of the findings of inspections carried out by its Environmental Surveillance Squad (ESS).

"Directions under Environment (Protection) Act, 1986 have been issued to 14 power plants, while under Air (Prevention and Control of Pollution Act), 1981 and Water (Prevention and Control of Pollution) Act, 1974, concerned State Pollution Control Boards were asked to direct six power plants to comply with the environmental standards," Javadekar said.

The power plants which have been issued directions include Paras and Koradi thermal power stations in Maharashtra; Patratu, Tenughat, Chandragupta power plants in Jharkhand; Kutch Lignite in Gujarat; Durgapur and Kolaghat in West Bengal; Rayalseema power plant in Andhra Pradesh, and Chhabra thermal power station in Baran district of Rajasthan.

The thermal power plants also include the ones at Korba (East), Korba (NTPC), Korba (West), Amarkantak (Lanco Power) in Chhattisgarh; Talcher (NTPC) in Odisha, Parichha, Anpara and Obra power stations in Uttar Pradesh, as well as, Muzaffarpur and Kahalgaon Super Thermal (NTPC) power plants in Bihar.

Javadekar said the directions were in different phases of compliance. He also informed the Lower House about steps taken by the Central government to contain pollution from the power sector.

Among them is stricter emission limit for particulate matter at 50 mg per Nm3 (Normal Cubic Metre) against the notified limit of 150 mg/ Nm3 for new power plants to be located in critically polluted area, urban area and ecologically sensitive area.

Tougher pollution laws soon, vows Environment Minister Prakash Javadekar

We plan to introduce amendments this session, Environment Minister Javadekar says; he is optimistic about land bill too.

The government will soon bring in changes to the law to provide for tougher punishments for pollution-related offences, Environment Minister Prakash Javadekar has said.
In an interview to The Indian Express, Javadekar said his ministry has finalised proposals to amend the Environment Protection Act, 1986, and plans to introduce these in the ongoing session of Parliament itself. The proposals have been submitted to the cabinet for approval, he said.

Javadekar also said the government would get the land bill passed in the current session of Parliament. “There is one week to go, and three more days for the Rajya Sabha. Many things can happen in eight days. Many things will be cleared,” he said.
Asked why he thought the opposition will change its stand on the land bill, he said, “Logon ko sadbuddhi aati hai (People are visited with good sense). So let us wait for the final days of the Parliament session.” Although the bill was not mentioned in its list of business for the week beginning Tuesday, the government said on Friday it would like to bring in the bill before the Lok Sabha concludes on May 8.

About the changes to environmental laws, Javadekar said, “Today, you can issue directions, you can register a violation, you can register a criminal case which never gets completed in a time-bound manner. So nobody gets punished in that process. Or, otherwise, you can only close the shop. But that is not the way. You cannot close thousands of industries. So there has to be a third thing. That means, you have to create a mechanism where we increase the penalties.”

(Source: PTI)Offences under the Environment Protection Act are punishable by a fine up to Rs 1 lakh, imprisonment up to five years, or both. The minister did not specify what the new ceiling of fines would be.
Javadekar conceded that there was “pressure” on India’s land and forest resources because of development needs. “We have only 2.5 per cent of the world’s land mass and have 17 per cent of the human as well as 17 per cent of the cattle population. Therefore, there will always be pressure but still we have to protect our environment and increase the forest cover. How can we do that? The answer is technology,” he said.
The Environment Ministry has been working on making “comprehensive amendments” to six green laws, including the EPA, to bring them in line with current requirements. Javadekar said the work will take about six months to be finalised.
“The T S R Subramanian Committee has given its inputs. Then all the states have given their inputs. All experts and others too have given their inputs. All of them have been put together and we have appointed a law firm to draft the laws. That will take about six months,” he said.
But a law on creating an authority to deal with compensatory afforestation funds, which was cleared by the cabinet recently, will be introduced in the current session itself, Javadekar promised. “CAMPA (Compensatory Afforestation Management and Planning Authority) is a major step.”
Javadekar said the Narendra Modi government has performed “miracles” on the environment front in its 11 months so far. “We have made processes transparent. We have started taking decisions. The ministry, which was seen as a speed-breaker and a tax ministry, we have converted into a facilitating and a very transparent ministry, where we are accountable for all our actions.,” Javadekar said

Neem Coated Urea
Indigenous manufactures/producers of urea are allowed to produce Neem Coated Urea (NCU) upto maximum of their total production of subsidized urea and to restrict the extra MRP to be charged by the companies selling Neem Coated Urea to the extent of 5% of the existing MRP of urea i.e. Rs. 5360/- per MT.

Further, it has been made mandatory for all the indigenous producers of urea to produce minimum 75% of their total production of subsidized urea as NCU for the year 2015-16.


Research on NCU by Indian Agricultural Research Institute, New Delhi indicated increase in the rice grain yield by 6.3% to 11.9% over normal urea.

NCU reduces consumption of urea by 10-15%. As far as environment is concerned, normal prilled Urea use-efficiency is 30% (Paddy crop) to 50% (Wheat crop) i.e. 50%-70% urea is lost/leached down resulting in nitrate pollution in underground water. In case of NCU, this loss is significantly reduced by about 10% – 15%, thereby resulting in less pollution of underground water. Moreover, the usage of NCU is environmental friendly.

Naphtha Based Fertilizer Plants
The Government has not given any assurance to the Naphtha based urea/ other fertilizer manufacturing plants that these plants/ would not be closed down. As per the Modified New Pricing Scheme (NPS)-III for existing urea units notified on 2ndApril, 2014, “the production of the high cost naphtha based urea units namely Southern Petro-chemicals Industries Corporation (SPIC) -Tuticorin, Madras Fertilizers Limited (MFL)-Manali and Mangalore Chemicals and Fertilizers Limited (MCFL)-Mangalore was to continue till the gas availability and connectivity is provided to these units or June, 2014 whichever is earlier, beyond which subsidy for naphtha based plants was not be paid.

The Cabinet Committee on Economic Affairs (CCEA), in its meeting on 27th August 2014, approved the operations of these three Naphtha based urea plants in the southern states, from 1st July 2014 to 30th September 2014 and subsequently in its meeting on 10th December, 2014 for 100 days from date of notification of its decision i.e. 7th January 2015. The CCEA Note for continuation of these three naphtha based urea units beyond 16th April, 2015 has been approved by the competent authority and will be sent to the CCEA after inter-ministerial consultations.

As directed by the CCEA in its meeting 10th December 2014, the Department of Fertilizers convened a meeting of all stakeholders to explore the other alternatives to supply gas to these Naphtha based urea manufacturing units and also review the status of conversion of these three naphtha based urea manufacturing units, availability of gas and gas pipeline connectivity on 09th March, 2015.

In view of analysis carried out by Department of Fertilizers, operation of these three plants on gas supply through Floating Storage & Regasification Unit (FSRU)/ gas tankers is technically not feasible. The commencement of supply by tankers and FSRU needs at least 24 months period after getting all necessary clearances. So gas supply through pipeline is the best option.

At present, MCFL-Mangalore and SPIC-Tuticorin are continuing urea production using naphtha as feedstock as per the direction of Hon’ble High Court of Delhi. However, MFL-Manali has shut down their plant from 17th April, 2015.

Environment ministry passes buck on vehicle emissions



NEW DELHI: The ministry of environment, forest and climate change has submitted to National Green Tribunal (NGT) that its role in curbing vehicular emissions is "limited" and confined to framing of air quality standards.

"The role of MoEFCC is limited to evolving/framing air quality standards under the mandate of the Environment (Protection) Act, 1986. In the present context, it is submitted that the ministry of road transport and highways is the authority concerned, as per business allocation rules, administering the Motor Vehicles (MV) Act and the rules framed for vehicular emission standards under the MV Act, 1988," the ministry said.

The submissions came in an affidavit filed by MoEFCC special secretary Shashi Shekhar in a case against high air pollution levels in the city. NGT had directed Union ministries and Delhi government departments to submit their views on banning of more than 10-year-old diesel vehicles, hiking parking fee, capping the total registration of vehicles in the city and other interventions.

The ministry said the revised National Ambient Air Quality Standards had been notified by it on November 16, 2009 under the Environment (Protection) Act, 1986, based on the studies undertaken by Central Pollution Control Board in association with IIT-Kanpur.

"The ministry had consulted the state governments of NCR...on April 6 and April 13 under environment minister Prakash Javadekar and prepared a plan. The plan says vehicles without PUC certificate will be challaned, lane discipline will be maintained, congestion due to breakdown of vehicles will be minimized, U-turns be provided at entry of interstate borders and congestion due to waterlogging will be curbed," the affidavit said.

Fourth strong quake rattles Papua New Guinea this week; local tsunami threat lifted


A powerful earthquake rattled Papua New Guinea on Thursday, the fourth strong quake to hit the South Pacific island nation in a week. The temblor prompted officials to issue a local tsunami warning, but it was lifted shortly afterward with no immediate reports of damaging waves.
The 7.1-magnitude quake struck about 150 kilometres southwest of the town of Panguna on Bougainville Island at a depth of 23 kilometres, the U.S. Geological Survey reported.
The Pacific Tsunami Warning Center said tsunami waves of up to 1 metre were possible within 300 kilometres of the epicenter on the coast of Papua New Guinea. The agency lifted the warning about an hour later.
There were no immediate reports of damage, said Chris McKee, assistant director of the Geophysical Observatory in the capital, Port Moresby. Because the epicenter was so far offshore, the chance of serious damage on land was less likely, he said.
“It’s not a particularly strong earthquake in global terms, but it could still have generated a tsunami, so it’s a bit too uncertain at this stage to be sure,” he said.
Thursday’s quake was located in a different area of Papua New Guinea than the previous three temblors that rattled the region over the past week, and was therefore an unrelated event, McKee said.
Gumu Pala, an officer with the National Disaster Center, said staffers were trying to reach their colleague in Bougainville for an update from the ground. So far, they had not made contact with anyone from the region, as communications were spotty.
Papua New Guinea sits on the Ring of Fire, the arc of seismic faults around the Pacific Ocean where earthquakes are common

Copper + Nitric Acid

Copper + Nitric Acid

 

Copper + Nitric Acid


Copper is a reddish-brown metal, widely used in plumbing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny.  (Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies.)  Copper is oxidized by concentrated nitric acid, HNO3, to produce Cu2+ ions; the nitric acid is reduced to nitrogen dioxide, a poisonous brown gas with an irritating odor:
Cu(s)  +  4HNO3(aq)  ——>  Cu(NO3)2(aq)  +  2NO2(g)  +  2H2O(l)
When the copper is first oxidized, the solution is very concentrated, and the Cu2+ product is initially coordinated to nitrate ions from the nitric acid, giving the solution first a green, and then a greenish-brownish color.  When the solution is diluted with water, water molecules displace the nitrate ions in the coordinate sites around the copper ions, causing the solution to change to a blue color.
In dilute nitric acid, the reaction produces nitric oxide, NO, instead:
3Cu(s)  +  8HNO3(aq)  ——>  3Cu(NO3)2(aq)  +  2NO(g)  +  4H2O(l)

In the following demonstration, a balled-up piece of thin copper wire is added to about 100 mL of concentrated nitric acid; once the copper is added the evolution of nitrogen dioxide occurs quickly.  Once all of the copper has reacted, the solution is diluted with distilled water, changing the solution from a dark brown to a pale blue color.
This demonstration can be done with copper in the form of shot, pellets, thicker wire, or bars, but is a great deal slower than with copper wire.




A Historical Sidelight:  Ira Remsen on Copper and Nitric Acid
Ira Remsen (1846-1927) founded the chemistry department at Johns Hopkins University, and founded one of the first centers for chemical research in the United States; saccharin was discovered in his research lab in 1879.  Like many chemists, he had a vivid "learning experience," which led to a heightened interest in laboratory work:
While reading a textbook of chemistry I came upon the statement, "nitric acid acts upon copper." I was getting tired of reading such absurd stuff and I was determined to see what this meant. Copper was more or less familiar to me, for copper cents were then in use. I had seen a bottle marked nitric acid on a table in the doctor's office where I was then "doing time." I did not know its peculiarities, but the spirit of adventure was upon me. Having nitric acid and copper, I had only to learn what the words "act upon" meant. The statement "nitric acid acts upon copper" would be something more than mere words. All was still. In the interest of knowledge I was even willing to sacrifice one of the few copper cents then in my possession. I put one of them on the table, opened the bottle marked nitric acid, poured some of the liquid on the copper and prepared to make an observation. But what was this wonderful thing which I beheld? The cent was already changed and it was no small change either. A green-blue liquid foamed and fumed over the cent and over the table. The air in the neighborhood of the performance became colored dark red. A great colored cloud arose. This was disagreeable and suffocating. How should I stop this? I tried to get rid of the objectionable mess by picking it up and throwing it out of the window. I learned another fact. Nitric acid not only acts upon copper, but it acts upon fingers. The pain led to another unpremeditated experiment. I drew my fingers across my trousers and another fact was discovered. Nitric acid acts upon trousers. Taking everything into consideration, that was the most impressive experiment and relatively probably the most costly experiment I have ever performed. . . . It was a revelation to me. It resulted in a desire on my part to learn more about that remarkable kind of action. Plainly, the only way to learn about it was to see its results, to experiment, to work in a laboratory.
from F. H. Getman, "The Life of Ira Remsen"; Journal of Chemical Education: Easton, Pennsylvania, 1940; pp 9-10; quoted in Richard W. Ramette, "Exocharmic Reactions" in Bassam Z. Shakhashiri, Chemical Demonstrations: A Handbook for Teachers of Chemistry, Volume 1.  Madison: The University of Wisconsin Press, 1983, p. xiv:


!!!  Hazards  !!!
Nitric acid is extremely corrosive.  Handle with care.
The nitrogen dioxide produced in this reaction is poisonous.  This reaction must be done in a fume hood!
