“…Problematisch mit Biodiesel aus Pflanzenölen sind neben der Nahrungsmittelkonkurrenz auch die hohen Rohstoffkosten, die diesen Biodiesel oft unwirtschaftlich machen (Canakci 2007;Math et al 2010). In den letzten Jahren wurde jedoch eine Vielzahl verschiedener Verfahren zur Biodieselerzeugung entwickelt: homogen oder heterogen katalysierte Prozesse, einstufige und mehrstufige Verfahren, enzymatisch katalysierte Prozesse und überkritische Prozesse (Banković-Ilić et al 2014;Guldhe et al 2015;Gumba et al 2016 Getrennt erfasste Altspeiseöle sind aufgrund der geringen Rohstoffkosten zur Biodieselerzeugung wirtschaftlich interessant (Kulkarni und Dalai 2006) und es existieren verschiedene entsprechende Systeme wie in Tirol das Altspeiseöl-Sammelsystem Öli (Ortner et al 2016).…”

“…These second generation feedstocks are generally produced from non-edible food crops or non-edible vegetable oils such as wood, waste, etc., in order to avoid the conflict associated with the first generation feedstocks. Included in the second generation feedstocks is waste or used cooking oil [13][14][15]. Numerous works have reported the potential of non-edible vegetable oils due to its physicochemical properties, its environmentally friendliness, and availability; allowing the production of biodiesel in a sustainable manner.…”

Abstract:The use of non-edible, second-generation feedstocks for the production of biodiesel has been an active area of research, due to its potential in replacing fossil diesel as well as its environmentally friendly qualities. Despite this, more needs to be done to remove the technical barriers associated with biodiesel production and usage, to increase its quality as well as to widen the choice of available feedstocks; so as to avoid over-dependence on limited sources. This paper assesses the feasibility of using a local plant, Reutealis trisperma, whose seeds contain a high percentage of oil of up to 51%, as one of the possible feedstocks. The techno-economic and sensitivity analysis of biodiesel production from Reutealis trisperma oil as well as implementation aspects and environmental effects of the biodiesel plant are discussed. Analysis indicates that the 50 kt Reutealis trisperma biodiesel production plant has a life cycle cost of approximately $710 million, yielding a payback period of 4.34 years. The unit cost of the biodiesel is calculated to be $0.69/L with the feedstock cost accounting for the bulk of the cost. The most important finding from this study is that the biodiesel from Reutealis trisperma oil can compete with fossil diesel, provided that appropriate policies of tax exemptions and subsidies can be put in place. To conclude, further studies on biodiesel production and its limitations are necessary before the use of biodiesel from Reutealis trisperma oil may be used as a fuel source to replace fossil diesel.

“…Used cooking oil is one interesting feedstock, with costs typically two or three times lower than that of virgin vegetable oil (Math et al, 2010). It has been reported that0.7 to 1 and 0.2 million tons of used cooking oilis annually produced in European countries and the United Kingdom, respectively (Hamze et al, 2015).…”

-The biofuel production from used palm oil (UPO) using supercritical ethanol (SCE) at low molar ratio was investigated in order to produce an entirely renewable fuel. The effects of the reaction time and ethanol to oil molar ratio were considered from 0.5 to 10 min and 6:1 to 18:1, respectively. The optimal parameters were 10 min and a 12:1 molar ratio, representing a remarkable reduction from 42:1 for the conventional SCE process. Because of the high operating temperature, the triglycerides conversion rate reached 99%, and the glycerides content met the international specification for biodiesel. However, an ester content of 70% was obtained at optimal conditions. The side reaction between glycerol and ethanol demonstrated a positive effect in increasing fuel yield by 8.15%. The product can be considered an alternative biofuel instead of biodiesel.
