Environmentally Sound Innovation To Make NZ Company Rich


I have mentioned before that countries that come up with innovations to mop up poisonous, polluting gases from our atmosphere, our waters and soil, will be wealthy. Very wealthy.

Well, what do you know? New Zealand's  Lanzatech has come up with affordable technology to mop up carbon monoxide from the atmosphere and produce ethanol. Who wants this technology? India, China and the US of A for starters! They have already signed deals with the company.

Why are such huge volumes of carbon monoxide (and carbon dioxide) spewed into our atmosphere in the first place? They are the end product of human activities like transportation, oil refining, chemical production and manufacturing industries. Our mountains of garbage also release these gases. (links to why these gases are poisonous for our health are at the end of this article.)  That is why mopping them up from the atmosphere is of the utmost importance. 


Morning Glory
Countries the world over have strict regualtions about the quantities of carbon monoxide allowed into the atmosphere. They are aware of how poisonous it is to anything living (like human beings or this beautiful flower, Morning Glory by Netalloy downloaded from open clipart) and of the need for these regulations. Companies have had to take that one extra step of converting carbon monoxide their factories spew out into something less harmful. Yet others, although environmental laws are in place, have simply continued spewing carbon monoxide into the atmosphere as the enforcement of these laws in their countries have been lax.

Many companies convert carbon monoxide into ethanol. Ethanol is a reusable and clean end product that doesn't poison our atmosphere. It has many uses. If used as fuel in transportation, for example, it wouldn't release carbon monoxide as its end product. The Americans already sell cars that use either petrol or a mix of 85% ethanol and 15% petrol   

The technology for converting these poisonous gases into ethanol has been available for years. Put simply, this is what happens.

Carbon monoxide with the formula CO has no hydrogen (H) in it.
Ethanol (C2H5OH) has a total of 6H. 2C and 1O

Hydrogen would have to be added to carbon monoxide to form ethanol.

In many industries the unwanted end products are exactly the above two - hydrogen, carbon monoxide - plus other gases. In steel mills the end product is carbon monoxide but no hydrogen. Many steel companies to date have converted carbon monoxide from steel mills to ethanol by adding the hydrogen required. Lanzatech has developed a microbe that can circumvent this step of introducing hydrogen altogether. Its microbe can actually produce the hydrogen required by using the carbon from carbon monoxide and the hydrogen from water. The process is so efficient that a lot of the water they use is returned to the reactor for reuse. Whatever the industry, whatever the proportion of carbon monoxide and hydrogen, the Lanzatech microbe can convert it to ethanol. Also, the process is tolerant to any number of contaminents (other gases) present in the reactor.

The production of ethanol thanks to the L-microbe (whatever Lanzatech decides to call it) will now be commercially viable, extremely affordable and socially / environmentally sound.


There are some companies that convert animal and human waste in our sewage to ethanol. But where Lanzatech promises to be different is that its microbe is as harmless as brewers yeast and its process affordable and efficient. I have no doubts that the three countries that have signed up with Lanzatech - India, USA and China - would have done their due diligence because not only are they all astute and business savvy, they have scientists equal to the best in the world.

To conclude I'd have to say -

Why some gases are Deadly Dangerous-CO

The last post asked what we'd do if we had to make a choice between the environment and some of our life giving activities. It is a tough choice to make. At a certain point in time will we have to make that choice? Not if we modify our activities to benefit both - us and the environment.

To be able to do that we first need to understand what exactly human activities have been responsible for. To date what we've done is, taken a resource from the earth, used it to make whatever's useful and ended the process there. We haven’t had to think about what by-product we’ve created.

All too often this has been a pollutant that poisons our air, waters and soil and damages our health.

1. This article tells us why certain gases like carbon monoxide are deadly dangerous for our health. It helps us understand why these gases shouldn’t be the end product of our activities.


CARBON MONOXIDE (CO)

How do human activities like burning coal emit carbon monoxide?
Ideally, burning coal should give carbon dioxide and water.
If you have a camp fire in the open air, there will always be enough oxygen to make the fuel burn completely, so you don’t have to worry about carbon monoxide. But, if you share the oxygen you breathe with too many appliances and people – for example, in an enclosed, crowded place, there isn’t enough to go around.
That is when coal or wood burns inefficiently; there is partial oxidation and instead of carbon dioxide or CO2, Carbon monoxide or CO is one of the end products.
CO is also naturally produced in volcanoes and forest fires.

============
Who is at risk? 
============

Anyone who works or lives in a very small or enclosed space, sharing it with many others, is exposed to harmful levels of carbon monoxide. People who work in factories, blast furnaces, who are in their vehicles in traffic - like drivers and traffic police, fire fighters and people who use coal and wood burners are at risk. In short, everyone in India is exposed to dangerous levels of carbon monoxide.

  • When it enters the bloodstream, CO reacts with the haemoglobin in our blood and forms carboxyhaemoglobin. This reduces the ability of haemoglobin to transfer oxygen to various parts of our body.

CO causes
  • headaches, fatigue, dizziness, drowsiness, or nausea.
  • Exposure to elevated carbon monoxide levels can cause impairment of visual perception, manual dexterity and learning ability

Carbon monoxide (CO) poisoning may occur sooner in those most susceptible - young children, elderly people, unborn babies, people with lung or heart disease, people at high altitudes, or those who already have elevated CO blood levels, such as smokers.
