WASHINGTON — Today, the U.S. Environmental Protection Agency (EPA) is announcing that 86 U.S. manufacturing plants earned the agency's ENERGY STAR certification in 2022, a designation reserved for manufacturing plants in the top 25% of energy efficiency in their sector. Together, these plants saved over 105 trillion British …
The energy use among the 15 plants depicted in Figure 4 varies from a low of 3.68 to a high of 6.87 gigajoules per tonne of clinker. The average energy use for the 15 plants is 4.69 GJ/t. But the average for the four most energy-efficient plants (upper quartile) is …
assessments, (2) energy teams, (3) employee awareness, and (4) energy monitoring. 2.3 Plant Energy Assessments . Plant energy assessments determine where and how much energy is consumed,and identify steps to improve the facility's energy efficiency and save money. The assessment can f ocus on the whole site or specific systems and processes.
Operational advances, such as energy-efficiency measures, have already largely been implemented, and the emissions-reduction potential from alternative fuels and clinker substitution is …
Adding 5% limestone would reduce fuel consumption by 5% (or on average 0.35 GJ/t clinker), power consumption for grinding by 3.3 kWh/t cement, and CO2 emissions by almost 5%. Additional costs would be minimal, limited to material storage and distribution, while reducing kiln operation costs by 5%. Low-Alkali Cement.
Owing to the large increase in energy costs associated with the oil crisis of the 1970s, more than 85% of cement kilns now use energy-efficient dry methods, which do not require additional energy ...
n.e.c = not elsewhere counted. CIS = Commonwealth of Independent States. BAT = energy intensity covers the process up to the liquid steel stage, i.e. it does not include energy used in casting and rolling, or energy used by captive thermal utilities (which are included in reported energy intensity).
ENERGY STAR signifies that these cement plants perform in the top 25 percent nationwide for energy efficiency and meet strict energy efficiency performance levels set by the EPA.
Other than saving costs, they will have to be mindful about being energy efficient and using a robust and reliable solution to manage the operations in the cement plants. Professionals engaged in cement plants today want innovative solutions that will help improve plant utilization, optimize processes & reduce energy consumption. We …
The direct CO2 emissions intensity of cement production has been broadly flat over the last five years, and is estimated to have increased slightly (by 1%) in 2022. In contrast, …

These slides are from the first of a three part webinar series on America's most energy-efficient manufacturing plants. During this webinar two of the nation's most energy-efficient plants, a glass plant and a cement plant, presented on what they did to improve the energy efficiency of their opeartions and earn ENERGY STAR plant …
The cement industry is likely to play a role in reducing greenhouse gas emissions to combat anthropogenic climate change. Many decarbonization pathways suggest that direct specific emission levels of around 350 – 410 kg CO 2 /t cement will be required. However, increasing clinker substitution, alternative fuel use, and thermal energy efficiency can …
product of cement) produced by 47 cement plants in Vietnam was 3,698MJ/ton. The thermal energy consumption for clinker production with the best available technology is less than 2,930MJ/ton. The release of CO2 from coal combustion and thermal inefficiencies have made the cement industry one of the most air polluting industries in Vietnam.
