На долю цемента приходится около 8% мировых выбросов CO2, что эквивалентно 1,6 миллиардам тонн углекислого газа ежегодно.
Сингапурские учёные разработали инновационный метод 3D-печати бетоном: в бетонную смесь возле печатающей головки вводят уловленный на предприятиях СО2 и водяной пар.
Углекислый газ карбонизируется, а бетон получается прочнее на сжатие. #технологии #вмире
