Going green is becoming a new way of life in start-ups. After Prime Minister Modi’s announcement that government will wave off the taxes for first three years of startups, many entrepreneurs are now thinking of starting their business which eventually demands for new infrastructure for many corporate offices.

It is necessity to go for green offices or buildings which consumes less energy and hence less pollution to the environment. Now we can Reduce, Reuse, Recycle and Rethink to eliminate waste and protect our Environment. Waste, we create has to be controlled to be sure it does not harm our Environment.

There are some easy ways to lessen impact on environment by going green, i.e. developing good habits which will eventually end you up in saving some pennies as well.

Less Energy, Less bills

Nowadays in major cities, most of the employees work (hardwork!) on computers, laptops, devices etc. We can set our devices on power saving or energy saving modes so that it can consume less power. Letting them standby for longer duration draw considerable amount of power which can’t be measured.

Also switch off lights and equipments when not in use in offices especially at night. Opt for eco-friendly bulbs i.e. LEDs which currently is being pushed by Indian government. (Fact: Indian Government has saved 1000 Crore rupees by distributing 2 crore LED bulb in a year.)

Dare to be digital

We all have observed that last page of most of the documents has only email address or web address where printable space is wasted. We can reduce that waste by using “GreenPrint” and “EcoPrint2” softwares which are designed for identifying blank spaces in documents and removing them before printing.

Is it necessary to send meeting agenda or minutes of meeting to printout? Can’t we send emails? Also too much paper is wasted in printing monthly newsletter, manuals and distributing among employees. Instead can we put it online and distribute link to everyone, which can save lot of paper, so the trees.

Go for environment friendly paper

There are some times where we can’t avoid use of paper, we can use recycled paper which are environment friendly. Also look for paper which is made from bamboo, hemp (cannabis plant) or organic cotton. Try to use papers from both the sides i.e. buy printers or Xerox machines that can print on both the sides. Always use smaller fonts, it can save lot of papers each week.

3839120462?profile=original

It is very great idea to use cloth towels in bathrooms to save tissue papers.

Instead of using paper cups in office use your own mug so that paper use and waste can be reduced or eliminated.

Stay healthy, live longer

There is so much amount of fuel wasted in traffic every day in cities like Mumbai, Delhi etc. We can reduce this waste by maintaining our car, choosing fuel efficient car, carpooling (BlahBlahCar), Public transit, biking, walking etc. some of the companies giving bonus to the employees who commute to office on bicycle and car-poolers is ways to go green at office.

3839120379?profile=original

Use stairs instead of elevator.

Working from home

Instant messaging, emails, video conferences, screen sharing and other telecommunication options nowadays make effective communication with no necessity of physically presence. It can save lot of time and fuel. Bonus is you will get to work in your boxers.

Conserve Water

Please stop using bottled water. Use your own bottle or stainless steel bottle to drink water in office. It has been observed flushing toilets is largest water user in office building. We can use water hippos in toilet cisterns to reduce flush volume and save water

If possible reuse waste water for flushing in toilets, floor cleaning or for plants. So that amount of energy spent to make water to drinkable water can be saved.

That’s all from us about ways to go green at office. We encourage you to star implementing simple and small go green ideas in your office as well as daily life before implementing bigger ideas.

Implications for Cleantech of the Global Agreement in Paris

 
The following Blog is reproduced from my personal website at www.dougcrawfordbrown.co.uk. All of my blogs relate to the topic of collective action problems. Other blogs in the series are in the archives of my personal website.

 
The Paris Conference of the Parties (COP21) meeting is over. Or perhaps it is better to say that the formal meeting has ended and the long work to translate an ambitious statement into on-the-ground change has begun. Just south of 200 nations have agreed the wording of the proposal for the next step forward now that the Kyoto Protocol has expired. 

The key accomplishment is that this wording has been approved by all of the major emitters including the US and China; the UK and EU are no surprise because they were already leading globally on the Kyoto Protocol. However a significant hurdle remains, best shown in the case of the US: moving this agreement past Congress, which has become increasingly dysfunctional as the Republicans have swelled their ranks with climate change deniers (a step beyond a ‘skeptic’). We were here before with the Kyoto Protocol, only to have Congress refuse to sign on. Still, there is much stronger global political and scientific consensus this time. No nation’s politicians will find it easy to deny this consensus. 

To what actions are we now committed globally and here in the UK? Keep in mind that this is more a framework for moving forward rather than a concrete strategy. There is much to be done in completing that wording and turning it into actionable items. The target of limiting the global temperature increase to 2 degree C is more firmly set. And for the first time, there is a stated aspiration to remain below a 1.5 degree C increase. However, it is almost irrelevant which target is adopted. Both require striking reductions in the carbon emissions of developed nations almost immediately, and significant reductions in the rate of growth of emissions from developing economies. 

The result? A significant decline in global emissions beginning by 2030. Both spell the impending end of the fossil fuel era, unless carbon capture and storage moves forward quickly. From this point forward, fossil fuels are likely to lose their immense subsidies that have made them cheap for so long, and will begin to pay for their use of the global atmosphere as a dumping ground. With such a change, low carbon energy will reach ‘grid parity’ with coal, where their costs of producing energy are the same as those of high carbon fuels. The market for new energy investment should shift accordingly. Fifty percent of new energy generation capacity in the past few years has been in renewables globally. Watch as that percentage grows in response to Paris. 

What specifically has been agreed? 

1. Each nation will produce 'intended nationally determined contributions' or INDCs to this reduction in carbon, publishing these every five years from this point forward. These are accompanied by a specification of greater transparency and checking of claims. Nations will be held to account if they fail to deliver on these promises, although what exactly is meant by 'held to account' is not yet clear. Naming and shaming? 

2. These nationally determined contributions are intended to decarbonise the economies of the world with energy that has significantly lower emissions of greenhouse gases. To meet a 2 degree target, developed economies will need to reduce by 80% on average between today and 2050, with a steady decline. Developing economies have until 2030 to begin considering their decrease 

3. The need for this transformation of energy production is to be met by an equally ambitious improvement in energy efficiency of economies, buildings, transport and industrial processes. How ironic and unfortunate that it comes just as the national government has rung the death knell for the Green Deal. It is time to revisit that decision. 

4. A global fund (100bn dollars per year) has been written into the agreement, to increase after 2025. It will provide finance to developing and vulnerable nations both to assist them in moving onto a low carbon pathway of development, and to help them adapt to whatever effects climate change brings. 

5. The role of forests has been brought to the fore, with the REDD+ (Reducing Emissions from Deforestation and Forest Degradation) programme now an integral part of the global strategy. REDD+ will keep the carbon of vegetation locked into ecosystems rather than burned and sent into atmosphere as carbon dioxide. 

6. There is now formal recognition that there will be climate impacts requiring adaptation of cities, economies and infrastructure. The language used in the agreement is “enhancing adaptive capacity, strengthening resilience and reducing vulnerability to climate change”. Nations are to produce communications on their efforts periodically. 

7. Finally (at least for this thought piece), there is a role for ‘international transferred mitigation outcomes’. These are similar to cap and trade (at least the ‘trade’ bit). If a nation finds it more desirable and perhaps cost effective to help another nation create mitigation projects, this will count towards to mitigation goals of the donor nation. The caveat: no double counting of emissions reductions allowed! 

Much work is ahead, but the scientific and engineering consensus is that achieving these goals will require an almost balanced effort to increase energy efficiency, reduce the carbon intensity of economies, maintain forests, and assist developing and vulnerable economies to mitigate and adapt. 

What innovations are needed? Low cost, thin insulation for homes. Solar panels with lower embodied carbon, perhaps from self-assembling organic molecules. High efficiency vehicles and the logistics system to make them work together. ICT advances to turn cities into smart ones. The list is endless, but then so is the innovation capacity of the research and business community. Watch this space for details as these innovations move from the shed to the lab to field.

submerged arc welding and operation rules

Submerged arc welding (including submerged arc strip cladding and electroslag strip cladding)is a welding method that arc burns beneath the fluxes. Due to its advantages of stable welding quality, high welding speed, no arc exposure and small fume, submerged arc welding has been the main way to weld pressure vessel, pipelines, beam column in structural steel fabrication. In recent years, although new type, efficient, excellent welding methods have emerged, the application fields of SAW are not influenced. From the point of weld metal weight portion by different methods, submerged arc welding process accounts for 10%, and doesn’t change too much over these years.


Attention:

  • Wheels of automatic welding machine and electric wires should have good insulation. During working, electric wires should be kept in good position to avoid torsion and getting burnt by slag.
  • Control box and welder shell should be connected to ground to avoid electricity leakage. Keep wiring board covered.
  • Pay attention to intense welding flash caused by welding flux shortage. It would damage your eyes. A protection glasses is necessary.
  • Keep semi-automatic welder torch in fixed position to prevent short circuit.
  • Submerged arc welding flux contains manganese oxide which is toxic to human health. Although it doesn’t generate as much as fume as shield metal arc welding, harmful gas and steam is still produced. Fume extraction and ventilation system is highly recommended.

India’s food and agriculture sector has emerged as a high-profit sector that plays a vital role in its economy, with agriculture comprising one of the largest contributors to the country’s GDP along with fisheries and forestry.  The Indian food industry is poised for huge growth, increasing its contribution in world food trade every year.

The food industry is under tremendous pressure to ensure that their activities are eco-sensitive and contribute towards sustainable development in the long run, but there is also internal pressure to maintain or increase profitability in the face of fierce competition. Hence, it is very important that growing environmental concerns are addressed swiftly and smartly. Major areas of environmental concern caused by food, agro and food processing industries include water contamination, solid waste generation and energy consumption, requiring interventions such as the following:

  • Waste Minimization and waste to energy projects
  • Solid waste management
  • Water treatment technologies
  • Resource conservation for product design
  • Sustainable production and consumption
  • Energy conservation practices
  • Environmental compliance

OBJECTIVES: On completion of the course, the participant will be able to understand

  • The complexity of ecosystem resilience and its linkage with sustainable consumption and production of food
  • Ways to minimize water and energy consumption
    • Waste minimization techniques
    • Environmental and quality compliance
    • Scope for GHG  emission reduction to combat climate change risk and food security

ozone layer depletion

OZONE LAYER DEPLETION

 

What is Ozone Layer?

Ozone Layer is a deep layer in earth’s atmosphere that contains ozone which is a naturally occurring, highly reactive molecule that contains three oxygen atoms. It is constantly being formed and broken down in the high atmosphere, 6.2 to 31 miles (10 to 50 kilometers) above Earth, in the region called the stratosphere. This lower region of stratosphere containing relatively higher concentration of ozone is called Ozonosphere. The average concentration of ozone in the atmosphere is around 0.6 parts per million. The thickness of the ozone layer differs as per season and geography. The highest concentrations of ozone occur at altitudes from 26 to 28 km (16 to 17 miles) in the tropics and from 12 to 20 km (7 to 12 miles) towards the poles.

Why Ozone Layer is necessary?

The ozone layer forms a thick layer in stratosphere surrounding the earth, containing large amount of ozone. The ozone layer was discovered in 1913 by the French phycists Charles Fabry and Henry Buisson. It has a property to block solar radiations of wavelength less than 290 nm from reaching Earth’s surface. Thus, it can absorb about 98% of UV radiations which can produce long term harmful effects on human beings as well as plants and animals.

 

Causes of Ozone Layer Depletion

During the last several decades, human activities have resulted considerable reduction of ozone layer in the atmosphere. It occurs when destruction of the stratospheric ozone is more than the production of the molecule. It was first observed in early1970s and was found to be more prominent in Polar Regions.

Ozone hole refers to the regions of severely reduced ozone layers. The two regions where the ozone layer has depleted is the middle latitude and atmospheric regions over Antarctica

Natural causes of depletion of ozone layer

Ozone layer has been found to be affected by certain natural phenomenon such as sun spots and stratospheric winds. But it causes only 1-2% depletion and that is also temporarily.

Manmade causes of depletion of ozone layer

The main cause of depletion of ozone layer is CFCs (Chlorofluorocarbons),halons(methyl chloroform),carbon tetrachloride, methyl bromide, etc. These are categorized as ozone depleting substance (ODS). CFCs are used in freezers, air cooling component, dry-cleaning, etc. methyl chloroform in adhesives and chemical processing, carbon tetrachloride in fire extinguishers.

These substances remain in the atmosphere for quite a long time and is not recycled in the form of rain on the earth and thus transported into the stratosphere.

 The emission of ODS account for roughly 90% of total depletion of ozone layer . These gases are carried to the stratosphere where UV radiations from the sun break them to release chlorine (from CFCs) and bromine (from methyl bromide and halons). The chlorine and bromine free radicals react with ozone molecule and destroy their molecular structure, thus depleting the ozone layer. One chlorine atom can break more than one lac molecule of ozone, while bromine is 40 times more destructive than chlorine molecule.

Effects of the Ozone Hole

 Depletion of ozone layer and increase in UV rays can also cause DNA damage which can also be catastrophic. Thinning of ozone layer means getting direct in touch with ultra violet rays which can cause skin cancer or skin irritation which can lead to death. A decrease in 1% of ozone layer can cause 5% increase in cases of skin cancer.

Exposure to UV rays has also increased the cases of cataracts which in turn affects people’s vision and could also cause an increase in people becoming blind.

Aquatic plants and animals are also not safe. UV rays can penetrate through water and can kill small plants and animals. If ozone hole keep on expanding, there would be very few plants which means less food in the whole world.

The effect of the ozone hole and the damage done to the layer is still not very well understood. Apart from the gradual decrease of the ozone layer all over the world, there is little quantifiable evidence of new holes appearing any time soon. Even so, a number of countries have been working towards mitigating the damage.

CFC’s have been banned, especially in aerosol cans and various electrical appliances. There have been many conventions held to discuss the methods that will slowly phase out the use of the gases. However, this has been met with a great deal of resistance from industries that are based on the production and use of the gases.

One of widespread and long lasting effects has been the public awareness towards the environmental issues facing the planet. As one of the first major man-made problems to be discussed on a public forum, it set the ground for public opinion and action on issues such as pollution, greenhouse gases, global warming and the climate crisis.

It also sparked off renewed research about how weather patterns and natural phenomenon may be disturbed small changes in the atmosphere. Ozone depletion is not as serious as it once was, but nonetheless it has had an impact on the planet.

The ozone layer does not face rampant ozone depletion anymore, as most governments and environmental agencies have worked hard to reduce the emission of CFCs. This has proven to be a success and is the base for further work in reducing dangerous emissions.

 

 

  

Given that these risks exist even when the ozone layer absorbs about 98 percent of UV light, a future with an even thinner ozone layer is scary indeed. In the 1980s, this frightening prospect motivated the scientific community and policy makers of the world to address the issue of CFC production, which resulted in the 1987 Montreal Protocol. Policy makers from different industrialized countries signed this treaty as a pledge to reduce their CFC outputs. International Day for the Preservation of the Ozone Layer is celebrated each year on the anniversary date of the treaty, September 16th.

The efforts seem to be working. Reports show that by 2049, the ozone will recover to 1979 thickness, which is when scientists believe the hole began to form . Many scientists believe the Montreal Protocol is responsible for this joyous recovery.
