As of now, there are two factories which help in filtering air and turn it into useful products. A Canadian and a Swiss company helps filter carbon dioxide from the air and convert it into pellets and fertilizers.
In 2015, a Canadian start-up company started a pilot project that would capture carbon dioxide from the air and turn it into a more beneficial product, pellets, Sciece Alert reported. The idea of turning carbon dioxide into pellets and restoring it underground and be later used as fuel was introduced by Carbon Engineering, a Vancouver-based company.
During its test facility, the company was able to extract 10 tons of carbon dioxide and is expected this year to help in the construction of a $200 million commercial plant. By this year, the company is expected to raise one million tons per day of carbon dioxide to supply 100 cars off the road annually. And on the year 2018, the company aims to start selling CO2-based synthetic fuels.
Chief Executive Adrian Corless said, "Removing carbon dioxide from the air and use it as a feedstock is a beneficial project. And with hydrogen, it can produce net zero emission fuels." On the other hand, this year, a Swiss company, the Climeworks announced its project to be capture carbon dioxide from the air and turn it into a useful product, according to Business Insider.
The Climeworks was based near Zurich, Switzerland and is the world's first company to commercialize the idea of capturing carbon dioxide and turning it into a fertilizer to grow crops in greenhouses. Its long-term goal is to capture one percent annual carbon dioxide emissions by the year 2025.
The technology to capture carbon dioxide from the air would cut fossil fuel use to zero and literally will reduce carbon dioxide emissions resulting to "negative emissions." However, Climeworks state it clearly that they would be permanently storing carbon dioxide upon capture, but there will be no negative emissions to be generated.
