What are the global projected quantities that could be realised for producing Biodiesel "from algae and wastewater"? ... a tenth of current diesel use; a hundredth? - It's not so simple when looked at in these terms.
That's the 'well' part of the equation; what about the 'wheel'? - nice clean methanol (of what ever source) sloshing around in a fuel tank has the potential (via the tech above) to turn (I'd estimate) three-quarters of it's chemical energy into driving (via a fuel-cell/e-motor) the wheels -full cycle- ... biodiesel is only suited for an ICE and will be lucky to return one quarter chemical efficiency full-cycle; plus it does nothing to encourage wider changes in infrastructure, etc.
