GHG emission.

6 Reasons why biofuels should be used

1) GHG Emission Saving

43) Biogas Production Alternative to MSW Management
Germany: 6,650 GWh/yr of Electricity produced.UK: 2.5 Million
tonnes of MSW 0.7% of the countrys electricityBrazil: Sugar cane
bagasse 3 GW/yr of electricity ~ 3% of the total energy matrix
4) Biofuel from Algae Wastewater treatment
6 Reasons why biofuels should be usedStudy Case: Dalton Area in
North Central GeorgiaCarpet mills + sewage : 40-55 million m3/yr
wastewater produced15,000 tons of algal biomass 2.5-4 million L of
biodieselRemove 1500 tons of Nitrogen and 150 tons of Phosphorus

55) Energy Supply Safety
6) Degraded Land Recovery
Feedstock (Biogas production): Switch grassGrow on degraded land
and help restore its productivity.
