    A comparison of biodiesel purification methods 

    Schabort, C.J.; Van der Walt, P.J.; Marx, S. (ETA-Florence Renewable Energies, 2013)
    The purification of biodiesel is of cardinal importance to ensure the final product meets industry standards. This final step in the production stage contributes a large portion of the cost attributed to biodiesel production. ...

    Waste butter and margarine as feedstock for biodiesel production 

    Schabort, C.J.; Visser, H.P.; Hartzenberg, A.; Venter, R.; Marx, S. (ETA-Florence Renewable Energies, 2012)
    The resulting bio-waste from butter and margarine factories should be disposed of in an environmentally friendly manner. Currently the bio-waste is either flushed into the municipal sewerage system or moved to landfill ...

    Conceptual cost of an integrated micro-algal biomass-to-liquids facility 

    Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)
    An order­of­magnitude cost estimate was conducted on a new integrated biomass­to­liquids (BtL) process that produces 2.6 million litres of biodiesel per year from micro­algal biomass harvested from the Hartbeespoort Dam. ...

    In-situ biodiesel production from sunflower seeds using liquefaction 

    De la Rey, Jaco; Marx, Sanette; Venter, Roelf (ETA-Florence Renewable Energies, 2015)
    One of the most expensive steps in the bio-diesel value chain is the extraction of oil from the seeds. Simultaneous extraction and transesterification will lower the overall capital costs of the process while enhancing ...

    In-situ biodiesel production from municipal waste water treatment plant clarifier effluent stream 

    Schabort, C.; Van Tonder, G.C.; Venter, R.J.; Marx, S. (ETA-Florence Renewable Energies, 2015)
    The natural occurrence of micro-algal species in water treatment plants introduces many operational problems. If one, however, considers the high lipid, protein and carbohydrate content, micro-algae become attractive as ...

    Conceptual design of an integrated micro-algal biomass-to-liquids process 

    Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)
    A new integrated biomass­to­liquids conceptual process was developed to produce 2.6 million litres of biodiesel per year from harvested micro­algal biomass. Three unconventional harvesting methods, a thermochemical ...

    Feasibility of cultivating Hartbeespoort Dam microalgae 

    Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)
    Three cultivation experiments were conducted to grow microalgae in three consecutively scaled-up laboratory systems, which consisted of one, five and 135-litre bioreactors. The highest productivity achieved under optimum ...

    Four novel methods for the harvesting of micro-algal biomass 

    Brink, Jaco; Marx, Sanette (ETA-Florence Renewable Energies, 2011)
    The harvesting of micro-algal biomass is one of the most inefficient and costly steps in the whole biomass-to-liquids (BtL) value chain. Harvesting costs may contribute between 20–30% of the total cost of micro­algal BtL ...

    Ultrasonic assisted biodiesel production 

    Schabort, C.J.; Marx, S.; Hövener, D. (ETA-Florence Renewable Energies, 2014)
    One of the biggest hurdles in the production of biodiesel is the high production cost compared to petroleum-derived diesel. Even though the mechanical agitation utilised during biodiesel production is effective, it is ...
