Construction is an industry that contributes significantly to global pollution. Specifically, the production and use of cement alone emit 2 billion tons of CO2 into the environment every year, ranking third in the top 10 sources of industrial pollution.
🌟 In response to the global trend towards sustainability, a group of researchers from the University of Colorado Boulder, the University of North Carolina Wilmington, and the US National Renewable Energy Laboratory have developed a unique carbon-neutral method by using cement that can be produced from biological limestone.
🎯 It is known that the team cultivated Coccolithophore algae capable of producing biological limestone by forming calcium carbonate deposits during photosynthesis. What’s remarkable is that the biological limestone version of Coccolithophore can be produced in real-time, rather than taking millions of years to form naturally.
🎯 Finally, this biological limestone is used to produce cement. What’s special is that this cement not only neutralizes carbon but also removes carbon by having algae absorb CO2 from the environment and store it as calcium carbonate.
💖 The successful research on this biological cement is a very encouraging sign for a global sustainable construction industry. Researchers worldwide, including those in Vietnam, are making efforts to develop recycled building materials that protect the environment, all working towards a new era for the construction industry: the era of sustainable construction!
