Specific primary energy savings for each energy efficiency measure based on case studies of plants and references to technical literature are provided. If available, typical payback periods are also listed. The report draws upon the experiences of corn, wheat and other starch processing plants worldwide for energy efficiency measures.

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 only 4 GJ/t. In other words, there is a 15-percent difference between the

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 …
