Making Bagasse

Energy, Emissions and Water Comparison between Bagasse, Paper and Styrofoam

 

How does Bagasse compare with its Paper, Styrofoam and Recycled Paper counterparts?
Table 1: Resources (inputs) required to produce one pound of materials.


Table 2: Bagasse values are set at 100% for benchmarking.

Conclusions:


 

What difference does it make?
Assumption: Let's assume that the average person uses 5 disposable items per day for one year and that the average household consumes 29.19 kWh of energy per day.7


Choosing bagasse products over its paper and Styrofoam counterparts saves energy, reduces emissions and conserves water.

By choosing Bagasse products over Styrofoam, he will: By choosing Bagasse products over Paper, he will:

The energy (8.32 kwh for each pound of paper and 13.10 kwh for each pound of Styrofoam) is multiplied by 1.33415210, which is how much CO2 gets released when 1 kWh is generated.
Total CO2/Tot. Energy Produced=4,065 million MWh/2460 million metric tons = 1.33 lbs of CO2 per kWh

“A gallon of gasoline is assumed to produce… 19.4 pounds of CO2."
"For 2003, MOBILE calculates values of 23.9 miles per gallon (mpg) for passenger cars."
23.9 miles per gallon / 19.4 pounds of CO2 per gallon = 1.2320 miles per pound of CO2.
106.69 * 1.2320 = 134.44 miles
187.22 * 1.2320 = 230.6550 miles
