Cement production contributes significantly to anthropogenic greenhouse gas emissions GHG a major contributor to global carbon emissions The environmental impacts of cement production have grown in recent years and it is urgent to reduce its carbon footprint Systems dynamics SD is a simulation method used to understand the nonlinear behavior of
Cement is a widely used construction material globally Its manufacturing contributes to anthropogenic CO2 emissions significantly However its alkaline compounds can absorb CO2 from the surrounding environment and engage in a carbonation reaction thereby functioning as a carbon sink As a major cement producer and consumer China has an
There are about 2 894 cement plants in China Figure 3b excluding Taiwan of which 56 clinker only plants 1 631 grinding plants and 1 207 integrated plants The national cement production capacity is about 3 243 Mt/year the National Key R&D Program of China 2022YFE0208700 the Fine Particle Research Initiative in East Asia
There s never been a more important time to build resilience into the core of the cement value chain the cement plant The cement industry is being hit hard by the COVID 19 pandemic with global demand for cement expected to decline by 7 to 8 percent in 2020—though these declines have been unevenly distributed across regions 1 Paul Roger Impact of COVID
Cement is of course a key ingredient of concrete so an obvious solution would be to reduce the amount of concrete the world needs But concrete is the second most widely used material after water and its global annual production is forecast to grow from 14 billion m³ today to 20 billion m³ by mid century as human societies urbanize
