　　An Australian pilot project taking carbon emissions and storing them in building materials aims to have a full­scale production plant by 2020.

　　Mineral Carbonation International(MCi)，an Australian company developing carbon­using technology will officially launch its technology and research program.The launch will include a presentation of the hour­long process bonding CO2-stored in large containers at one end of the warehouse-with crushed serpentinite(蛇纹岩) from the nearby islands，forever turning it into solid carbonates(碳酸盐).MCi said，"These carbonate by­products have the potential to be used in building products such as concrete to create green construction materials."

　　By 2020 MCi hopes to be producing 20,000 to 50,000 tonnes of the bonded material for building companies，and it also expects the process will be economically workable even without a high carbon price."There's a big demand among consumers for green building products.The interest around the carbon brick has been extraordinary，but we're going beyond that，" said Marcus Dawe，chief executive of MCi.And in May the federal government said it would lift restrictions on the Clean Energy Finance Corporation to allow it to invest in carbon capture technology.

Dawe said serpentinite was an easily available raw material to absorb CO2，found around the
