The Water Pyramid

I was shocked to read the Newspaper Headline "Fill your water buckets today". The Bangalore water supply is shutting all valves to link the new water supply to provide 100 million liters of drinking water to the Bangalore city.

The Big Question is "How far can we survive like this?". It was then I stumbled into Acumen Fund's monthly report & the projects they support.

Aqua Aero Water Systems (AAWS) is project supported by Acumen, that has patented a technology the “Water Pyramid".

Aqua-Aero WaterSystems has developed the WaterPyramid concept for tropical, rural areas. The WaterPyramid combines state of the art technology, capacity building and local entrepreneurship in order to achieve a long lasting (financial) sustainable situation. The WaterPyramid makes use of simple technology to process clean drinking water out of salt, brackish or polluted water. Most of the energy needed to clean the water is obtained from the sun. The application is designed for tropical or subtropical regions around the world, where flat ground space is available together with abundant radiation from the sun.

Benefits:
  • Drinking water made easily available
  • For remote and local application
  • Low operational/maintenance costs
  • Can be used for income generation
  • Workforce can be locally recruited and trained
  • WaterPyramid can be locally produced
  • Based on Appropriate Technology

Garbage City to Garden City: NGO's on a mission

Huff, finally I have managed to post my first blog after innumerable reminders from Anand and co :) Let me add on to what Anand has already made a point about waste management and the efforts of various NGOs.
It really hurts to realize that Bangalore, what was once termed as the Garden City is now being termed the Garbage City. What hurts even more is the attitude of the so called educated people with absolutely no civic sense. Even when there is a trash can in plain sight (outside fast-food restaurants, for example), no one bothers to use it. Wrappers are strewn on the sidewalk, banana peels fly out of rolled-down widows of cars, straws are dropped nonchalantly on the streets as are plastic drinking cups, empty sites are promptly co-opted to be garbage dumping sites ("flip that garbage over the fence, no one is watching").It's definitely not the case that Bangaloreans are not clean. They all keep their houses clean, the fronts of their houses clean, their backyards clean. But this attitude towards cleanliness just doesn't translate to keeping the streets clean, keeping the community clean, not dumping garbage in the neighbor's empty site, not dropping garbage on the streets wherever one feels like it. And here I'm talking about people with education and with good jobs. The ones that are supposed to know better.
You speak to them, and they hit back “Why should we bother? The Municipal Corporation will take care of it”. Let’s not debate about whether it’s possible to change the mindset of such irresponsible … (Use whatever term for such people.).
Well, I do agree that there’s a sizable population who do care about the surroundings, the environment, and have civic sense. Most of us know the difference between bio-degradable and non-degradable substance and the ill-effects of non-degradable substances like plastic. What lacks among people is the awareness of how to safely dispose the garbage we generate. The simplest solution is to hand over the garbage to the doorstep garbage collectors. As responsible citizens, we should know that the waste we throw adds up to huge piles outside our cities and therefore polluting our surroundings. Most of the waste is just burnt - expelling toxic waste into the air, or just strewn around at certain places, which are far off from the city - but with current pace of development how far is it gonna go is anyone’s guess! Its time we make a difference – starting from home.


There are a lot of NGO’s, individuals who have put in a tremendous amount of effort to make a difference towards waste management. Below mentioned are just a few of them.

SAAHAS
--------------
Anand has already mentioned about this organization in the previous post.

DailyDump
--------------
http://dailydump.org/us.htm

A novel concept of composting your kitchen waste at home. Hats off to Poonam, the Brain Child of this product, for the amount of effort she has put into this. DailyDump offers a variety of compost pots named Gamla, Patta Kamba, Leave-it pot, Kamba etc for various needs of your home.

The compost that results can be directly added to the plants. No other fertilizer can substitute this manure. You can enjoy watching your plants bear fruits like never before.
I picked up one of the kambas last week and I must say each and every one must pick up one of these. These terracotta pots are so well designed; they can be used as a decorative piece!! Priced at Rs 500 for a non-painted and Rs 600 for a painted, it’s definitely worth it.
All you have to do is put the kitchen waste into these pots and leave them to decompose.

KK Plastics
-------------

Everybody knows the ill-effects of plastic. But what do we do with it? How do we dispose it? Well, Mr K Ahmed Khan has the perfect solution to end this menace. He has come up with the concept of mixing plastics with bitumen to lay roads.
His company KK Waste Management Pvt Ltd [KKWM] now offers Rs 6 per kg of plastic!! Barring rigid plastics, they accept all manner of film waste without the need for sorting. Considering that Bangalore generates 30 MT of waste per month, the potential of the idea to clean up the city is clear. Also, the money will be going into the pockets of our game rag-pickers and housewives. In fact, needing almost 2 MT per km of road laid, KKWM would be running short of waste!!
More on this.. http://www.goodnewsindia.com/index.php/Supplement/article/plastics-recycling-is-out-in-the-streets/P0/

So what next??

Now that we are aware of some of the organizations that work towards waste management, it’s our turn to do our bit. Segregation at source (home) is one of the most important and wish will be followed at every household. Waste can be segregated as
1) Bio Degradable and
2) Non Bio Degradable.

Bio Degradable waste include organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves from the garden, and paper.

Nonbiodegradable waste can be further segregated into:a) Recyclable waste – plastics, paper, glass, metal, etc.b) Toxic waste – old medicines, paints, chemicals, bulbs, spray cans, fertilizer and pesticide containers, batteries, shoe polish.c) Soiled – hospital waste such as cloth soiled with blood and other body fluids.Toxic and soiled waste must be disposed of with utmost care.

Lets just make a rough analysis of the kind of waste generated from a household and how we can handle this:
1) Kitchen waste: (Organic and bio degradable).
Kitchen waste contributes more than 50% of the daily waste. Bangalore produces about 3000 tonnes of waste everyday. The centralized government composting plant is capable of handling only about 500 tonnes per day. The rest reaches dumps that are illegal. If each one of us has a composting pot (dailydump) at home, I’m sure there would not be any need for an alternate solution. If you cannot buy one, atleast separate this waste and hand it over to the door-door garbage collector.

2) Newspaper
Now I’m sure nobody would throw away their daily newspapers!!Every1 would definitely find some space, under the cot, on an attic, cupboards, you name it and there will be space to store your old newspapers. This is cos, we have paid for these newspapers and we can gain back at least part of it by selling it to the kabadiwalas or the man who buys old newspapers.

3) Milk/ curds packets
When you can find place to store your newspapers, it should not be hard to store your milk and curd packets too. These too fetch decent money.

4) E-waste like dry cell batteries, electrical wires, non functional electronic/electrical items.
Saahas has a solution to manage your e-waste. They have placed recepticles at various locations in Bangalore. Find one closest to your place and drop them there. (http://www.saahas.org/ewasteprogramme.pdf Page 9).

5) Plastic covers ( Food packaging covers, Shampoo packets etc)
KK plastics pays Rs 6/Kg. If you cannot give it to them atleast hand it over to the nearest kabadiwala.
6) Bottles
PET bottles, glass bottles do fetch money. Hand it over to the nearest kabadiwala.

Apart from these I cant think of anything else that can add to the waste substantially. I really don’t see any reason why one should face problem in segregating their wastes. Now if you are wondering why you should take all this pain in segregating, when the pourakarmikas, or the people who collect the garbage door-door can segregate and in turn sell what ever is valuable, well the truth is they pick up only those items which are of high value and can fetch some decent money (Like PET bottles etc). Most of the other low value wastes which still can be recycled are not picked and find a place in the landfill.
Its time for each one of us to be responsible citizens and spread the word about these NGOs and ACT NOW.

Nanosolar - The Sun power at your Doorstep

Sun always has been the most energy provider source for Earth & Nanosolar is tapping the right source. Nanosolar is a developer of solar power technology. Based in Palo Alto, CA, Nanosolar is developing and commercializing an extremely low cost printable solar cell manufacturing process. Nanosolar coatings are as thin as a layer of paint and can transfer sunlight into power quite efficiently.

Nanosolar was started in 2001 by Martin Roscheisen and Brian Sager, who met through their friend Reid Gershbein, and is headquartered in Palo Alto, California. The company has received financing from a number of technology investors including Benchmark Capital, MDV, and Larry Page and Sergey Brin, the founders of Google. Nanosolar received the largest amount in a round of Venture Capital technology funding, amongst United States companies during Q2 2006, with 100 million USD of new funding secured.

Solar powered buildings and homes might just become standard in the future, thanks to this innovative technology by Nanosolar Inc. Nanosolar has developed proprietary process technology that makes it possible to produce 100x thinner solar cells 100x faster. The underlying technology for these solar cells is nothing new, having been around for decades, but Nanosolar has created the actual technology to manufacture and mass produce the solar sheets. The solar cells are produced by a solar printing press of sorts rolling out these aptly named PowerSheets rapidly and cheaply. The machines apply a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil reducing production costs to a mere tenth of current solar panels and at a rate of several hundred feet per minute. The first commercial cells for consumer use are scheduled to be released this year.

These solar cells successfully blend the needs for efficiency, low cost, and longevity and will be easy to install due to their flexibility and light weight. In order to compete with the energy produced from coal solar has been in need of finding a way to shrink its costs down from $3 per watt to $1 per watt. Nanosolar's cells use absolutely no silicon as is the standard for current solar production and the efficiency of the PowerSheet cells are competitive with the traditional systems as well. The golden kicker, the cost to produce these solar coatings is a mere 30 cents per watt!!

Nanosolar has built what is soon to be the largest solar plant in world in San Jose and once full production begins early next year the facility is capable of producing a whopping 430 megawatts per year, more than the combined total of every other solar manufacturer in the U.S. The biggest problem for Nanosolar is keeping up with the impending solar boom. California recently launched the Million Solar Roofs initiative providing tax breaks and rebates to encourage the installation of $100,000 solar roofs per year for a solid decade. Thanks to the innovative approach Nanosolar is poised to launch the solar revolution and we the consumer stand to benefit greatly as the result.

It's time the Sun shines real bright!!!

Saahas - The Waste Management People

As you drive around Bangalore you get to see lot of things – Beautiful Trees, Buildings under construction, heavy traffic & above all lots of garbage.

Talking about garbage we still see rag pickers segregating the waste to pick up the best of the scrap, however in this exercise they spread the garbage more. Some years ago many localities decided to adopt home garbage pickup model – where the garbage is collected from the doorstep instead of the person throwing it in the garbage bin. This works fine for a residential locality but the commercial or the areas where the pickup is not adapted still suffers. Bangalore generates 3,000 tonnes of waste everyday from households and commercial establishments. Around 50% of this waste is organic. The balance is accounted for by inorganic and hazardous waste.

Bangalore City Corporation has come up with a new scheme where they will pay plastic waste Rs.6 per kg directly to whoever gives it at their collection point. The plan is to set up around 120 collection points.

Saahas is a Bangalore based voluntary organisation are committed to finding solutions to problems related to solid waste management in the city. Saahas is ready to adopt one of the 120 collection points with the support of the Bangalore City corporation to make JP nagar 6th phase a plastic free zone. The initiative plan is being drafted & is being presented to the Bangalore City commissioner soon.

Saahas also work with Corporates on waste management. Project Satyam – they are composting their organic material in the same campus. They also work with Lalbagh Botonical garden on the same purpose.

Citizens E-Waste Recycling Initiative
Over the last two years, Saahas has worked closely with the Hazardous Waste Management, Programme Karnataka (HAWA), to study the various issues related to generation of e-waste as also its flow, recycling and final disposal.

Bangalore generates around 4,00,000 dry cell batteries from households and commercial establishments. Earlier there was no possibility of recycling this material safely. However, E-Parisaraa has come forward to ensure safe recycling and disposal by retrieving the metal and plastic components which in turn are recycled into secondary products. The hazardous content is then extracted and stored for disposal in the hazardous waste facility which is currently being set up close to Tumkur, near Bangalore.


Saahas is working in partnership with WeP Peripherals and E-Parisara. They have setup the first ever city wide collection programme for household e-waste like batteries, cds & floppies. One of the centers is in the State Bank of India branch. They have also setup these collections points in more than 20 schools around Bangalore. Hope this effort really pays of in making a bangalore a better place.

The COMPOSTABLE Water Bottle.

At last my first post on this blog :-)

Water:
A common chemical substance that is essential to all known forms of life. We all know the importance of it, I need not explain more.

I still remember 10 years ago people used to talk “who will buy water? When we get it for such a cheap price”, but life has changed today. Day in & out we buy water without a second thought. Quality is what we look at. The supposed to be corporation clean tap water is made to run through all kinds of Water purifiers before drinking at homes. But the point I am driving today is not about water it the way it is sold.

Packaged water in India is sold in Plastic bottles in all kinds of sizes starting from ½ liter, 1 liter & 2 liters.

Municipal solid waste in India contains 1-4 per cent by weight of plastic waste. India’s rate of recycling of plastic waste is the highest (60%) in the world as compared to other countries (China 10%, Europe 7%, Japan 12%, South Africa 16% and USA 10%) but is a much unorganized sector.

Today I want to talk about this wonderful organization called "Belu Water". This is a UK company providing mineral water in the UK. They are first company to provide UK's first COMPOSTABLE bottle made of corn and their profits go to clean Water projects in UK, Mali & India right now. They plan to take up projects similar to this around the world. They are also a Penguin Approved - They are anti-Global Warming.


To talk about their Bio-bottles - they are made from corn but could equally well be made from potatoes, rice, beetroot, bio-mass or pretty much any carbohydrate or sugar. The corn goes through a fermentation and distillation process similar to making corn whiskey and is reduced to a monomer called lactic acid (which you can also find in ice cream and pickles). This lactic acid is then spun, linked into polymer chains and molded into bottles.


Even though their bottle is compostable their cap is not. They request to reuse the same.

Read more about them on http://www.belu.org/

I wait for their launch in India & hope it makes a difference.

As Ed Rendell quotes Bottled water was, at best, a temporary solution for this community,but we have made it now a permanent solution.
