Global climate is changing and we’ve already seen its effects on the environment. For example, Glaciers have shrunk, ice on rivers and lake is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. These all are the effect that scientists had predicted in the past had now become reality. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists around the world, predicts that increases in global mean temperature of less than 1 to 3 degree Celsius will produce beneficial impact in some regions and harmful ones in others. It will create a chaos.

The greenhouse gases play an important role in global temperature increase. Co2 is also a greenhouse gas which is 0.04% of the whole atmosphere. And it is increasing exponentially as time passes. So to minimize the carbon dioxide from the atmosphere a Swiss company named Climeworks has launched its new venture. It will remove Co2 from the air directly and transform it into useful products.climeworks-technology

How does it work?

Co2 collectors

The whole project depends on the process that extracts the Co2 molecules from the air. For that, huge Air collectors have been installed on the garbage incineration plant’s roof with filters inside them. So when the air passes through it the Co2 molecules present in the air will chemically bound to the filters. Once these filters achieve its limit then they are heat treated at around 100 degree Celsius. The Co2 is then released from the filter and collected. Co2 free air is released back to the atmosphere. This cycle continues again and again. The filter can be reused many times.climeworks-technology

The collected Co2 can be used in food and beverage industries, commercial agriculture, the energy sector and automotive industry.

The first plant will be established outside of Zurich, Switzerland with 18 carbon dioxide collectors being installed on the roof of garbage incineration plant. The current plant has the capacity to capture 900 tons of carbon dioxide a year. To reach the goal of reducing the global Co2 level by 1% more than 2,50,000 additional plants would need to be installed.
