Comparison of Microalgal Oil and Diesel
Rough Excavation Cost Need approx 25,000 of 980.0 square meters of 0.30 meter
deep trenches for raceway ponds. Is approx 10,337 cf of “dirt” removed for each pond.
Excavation includes machine excavation with front end loader or backhoe, two trucks with 30 minute trips per load. Dumping fee not included.
Have not taken into account any tree or rubble removal from site or any concrete laying etc. Only dirt dig and removal.
Rough Excavation Cost May be able to sell dirt from dig.
Labor cost is $1,156
Cost of removal of cf of “dirt” is $7,649
Total is $8,805 (per pond) X 25,000 ponds = $220,125,000
Estimated from online calculator “HomeTech Cost Estimator”
Plant Cost Algae Production
$220,000,000 Does not include cost of PBR tanks and FDSF
Extraction $24,000,000 Scaled from soy crush plant estimates
Biodiesel Production $183,564,777 Scaled from DOE data
Plant Cost Total Estimate
$427,564,777
