The world’s population continues to grow and in many countries, they’re racing to build more to accommodate that growth. But with more construction, comes more emissions.
Innovators are racing for solutions to incorporate biomaterials like algae, to reduce the environmental impact of in demand materials like carbon fibre.
Watch the full RAZOR episode on our YouTube channel to find out how scientists are trying to turn construction green. Just look for the RAZOR science show.
00:01There's a movement growing to develop alternatives, incorporating biomaterials found naturally into buildings.
00:11At the Technical University of Munich in Germany, they're developing a literally green alternative to one of the most in-demand building materials.
00:20The team take the algal biomass and process it to produce yeast oil, which is treated to produce glycerin, which is then converted into polyacrylonitrile, the basic material in the manufacture of carbon fibre.
00:42Every carbon atom that is in this fibre was formerly CO2, and with the process that we're currently practising, we're not only becoming carbon neutral, we're becoming carbon negative.
