The production of cement results in significant GHG emissions. The emissions are caused by the decomposition of calcium carbonate $($limestone$)$ to calcium oxide $($lime$)$ and carbon dioxide. This process, known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns.

A large cement manufacturer uses a mix of coal, natural gas and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of Energy:

$205lbs$ CO$2/$MMBtu

$5lbsCH\frac{4}{M}$MBtu

$\mathrm{.}36lbs$ N$20/$MMBtu

Process carbon emissions from the calcination process produce $925lbs.$ of carbon dioxide per metric ton of cement. In addition, the plant uses $1\mathrm{.}7$ Million BTUs of energy per metric ton of cement. If the plant produces $180,000$ metric tons of cement annually, how many metric tons of $CO2e$ does it emit?
