Biomass contains stored chemical energy from the sun that is produced by plants through photosynthesis. Biomass can be burned directly for heat or converted to liquid and gaseous fuels through various processes. Biomass was the largest source of total annual U.S. energy consumption until the mid-1800s.

The majority of the energy needed and the CO 2 emissions are products of the calcination process; the pre-calciner uses around 60% of the total energy and produces unavoidable "process" emissions, around 60% of the total CO 2 from the cement plant. 2, 3 Once the mixture leaves, it enters the rotary kiln, where reactions occur at 1,450°C ...

Biomass energy, or "bioenergy," is the energy from plants and plant-derived materials. Biomass has been in use since people first began burning wood to cook food and keep warm. Wood is still the largest biomass energy resource today. Other sources include food crops, grassy and woody plants, residues from agriculture or forestry, oil-rich algae ...

The type of biomass utilized by cement plants is highly variable, and is based on the crops that are locally grown. For example rice husk, corn stover, hazelnut shells, coconut husks, coffee pods, and palm nut shells are among the many varieties of biomass currently being burned in cement kilns (Murray & Price, 2008).
