Come è noto i cementifici sono tra i più grandi consumatori di energia. Saranno infatti tra le prime aziende a poter beneficiare, in Sicilia e Sardegna, del “Decreto Legge Alcoa” approvato al Senato.
L’alta intensità energetica della produzione makes concrete and cement industries produce large amounts of CO2 : The figure shows a production amounting to 5-8% of national production in most industrialized countries.
Attempts to reduce the amount of carbon dioxide emitted from these plants is in progress for some time. Just in England Novacem presented a more sustainable product . Compared
the past few minerals are used as additives designed to produce cement at lower temperatures (less energy) and absorb CO2 during the curing product.
This will save energy and CO2 during production and it absorbs more CO2 when the cement is used. The idea is obviously attractive, even if some are not yet clear data as the amount of CO2 that is saved and the final cost of the cement.
Other ideas on sustainable cement "instead come from the United States, from Texas where study CHK Group would find a way to produce cement using also scraps of rice processing: taking the skin, it is cooked in special furnaces without oxygen (such as those of cement) and you get pure silicon, carbon-free, which can be added to the concrete. In this case is reused to make a difference a consumer product without any CO2 emissions.
finally arriving seems to be functional and innovative solutions to effectively reduce CO2 production.
