Aresearch pilot plant in newcastle will trial world-first technology that turns carbon emissions into bricks and pavers for the construction industry. when it comes to global warming, human beings are stuck between a rock and a hard place. on one hand, greenhouse gasses are inevitably pumped into the atmosphere through industry, power generation, and natural processes. on the other, emissions that contribute to climate change destabilize the systems on which people rely to survive. this new facility will hopefully change that. the plant will be located at the university of newcastle, and mineral carbonation international (mci) is expected to spend $9 million over a period of four years to establish the facility. the bricks can be used as construction materials, and they act as physical carbon sinks. lan smith, the chief executive of orica, told abc news that he believes the technology could be used by power plants across the world. "so this would enable, not just us as a company, but all the coal fired power stations around the world to be retrofitted so they can capture their co, off-take. it's an alternative solution. if you look at just storing it underground that only works in certain geological formations. this can work wherever those power stations are." other applications include utilizing the rock for street pavement and green construction. with co2 levels having reached over 400 parts per million this year, this type of technology is critical to slowing the trend of global warming. fifty carbon capture plants around the world could potentially sequester over a billion tonnes of co2 annually. a) how many tonnes of co2 are currently in the atmosphere, using the most recent available measurement of 416 ppm? b) in discussion with a member of the public (friend, parent, sibling) who is a non-scientist, explain the relative amount of co2 that would be captured, using the scenario in the article, compared to the current co2 in the atmosphere. c) in discussion with a fellow scientist (e. g. a fellow first year chemistry student) and using the graph below, evaluate the impact of this carbon capture strategy on the annual carbon loading to the atmosphere.
