Cement production also produces a high amount of CO 2 accounting for almost 5% of the world’s anthropogenic CO 2 emissions. 7 Approximately 337 billion tons of carbon have been emitted through cement production and the burning of fossil fuels since 1751. 8 The amount of carbon released from cement production has more than doubled since the 1970s. 9 A single ton of cement produces about 0.9 to 1.0 tons of CO 2 with 50-55% derived from the chemical reaction during the calcination of ...
Top 4 Environmental Compliance Issues at Concrete Plants
Regardless of your size product or organization structure there's some common environmental issues at every concrete plant I've ever been too. 1. Stormwater. By and large the concrete industry has figured out how to handle process water. We usually find our clients aren't having an issue with it so much as with stormwater.

Environmental impact of concrete - Wikipedia
The environmental impact of concrete its manufacture and applications are complex. Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth the topsoil. Concrete is used to create hard surf
Methods to Reduce Environmental Impact of Concrete
Cement Conservation to Reduce Environmental Impact of Concrete The conservation of cement is the first and most important step in decreasing both energy utilization and greenhouse gas emission. Resource productivity consideration stipulates the deduction of the utilization of Portland cement while meeting the future demands for more concrete.
ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION
Environmental impacts. The main environmental issues associated with cement production are consumption of materials and energy use as well as emissions to air. Waste water discharge is usually limited to surface run off and cooling water only and causes no substantial contribution to water pollution.
