“…Taking a look at the work done on the waste cooking oil to biodiesel technology, we come across a lot of work on the type of catalyst that should be used for transesterification [59,60]. Another area that the scientific community has contributed to the knowledge about the technology is the assessment of the fuel on whether it is suitable to be used in existing energy systems [35,43,61]. Such studies have established the foundation for the researchers to build on to experiment on the real life adaptability of the technology.…”

“…Use of different catalysts has been studied to improve the process to an extent that the FAME yields of over 90% have also been reported using different catalysts and conditions [38][39][40] The use of homogenous, heterogeneous, nanocatalysts has been studied but overall the performance of the process when catalyzed by alkali, alkoxides, hydroxides and alkaline metal oxides has been reported to be the most effective and if we compare the acid-base catalysts, the acid based catalysts have been found to be performing better under the higher alcohol to oil molar ratio exposure at moderate pressure and temperature [41,42]. Various studies have also been performed analyzing the properties of the produced biodiesel as a fuel in conventional internal combustion engines and the fuel has been reported to be very competitive in the fossil fuel dominated liquid fuel arena, used both in the form of blends and independently [43][44][45][46]. Studies to evaluate the economics around the waste cooking oil to biodiesel have also been carried out, most of which have concluded in finding the cost of biodiesel to be less than the petro diesel with the payback period for the biodiesel production reported to be around 4 years which can vary depending upon the country and the conditions put on in the model [47,48].…”

Techno-spatial assessment of waste cooking oil for biodiesel production in Pakistan

This study presents a take on employing the principles of waste valorization to solve the long-standing problem of finding sustainable resources for biodiesel production. The biodiesel production has always met with a competition with food security and land use. This has limited the scope of the technology to laboratory experiments only. This study aims to assess the geospatial availability of waste cooking oil in Pakistan to map its biodiesel production potential. Owing to the resource posing no land use or food security challenges, a resource assessment using geographical information systems was carried out. The waste cooking oil availability was estimated using the statistics on per capita edible oil consumption with a realistic consumption and collection factor applied to it. The available residual cooking oil was subjected to the transesterification with a rather conservative conversion to the biodiesel at 66.25% to keep the estimates realistic. The study results in heat maps of all the different regions and provinces of the country. The findings suggest that Punjab province is the highest potential province with 249,260 tonnes of biodiesel production annually. Karachi district is the highest potential district with a potential of 36,156 tonnes of biodiesel production in a year. The study paves ways for investment sector in the study area to identify highest potential regions to invest in. It also motivates the scientific community to step outside of experimental research on waste cooking oil's biodiesel production potential and perform resource assessments and techno-economic analyses on the technology for its widespread adoption.Graphic abstract PS-The callouts do not represent any geographical locations instead they represent the shade of the gradient they correspond to in terms of red being the gradient shade for the problems and the green being the gradient shade for the remedial contributions made by the study. The use of the map of the study area is because of the contextual important of the map in a resource and potential assessment that is geospatial in nature.

“…Over the past two decades, biofuels have gained continuous interest due to the renewable feedstock and their short life cycle [1]. Biodiesel and its blends with diesel are currently investigated as a viable solution to the problems of fossil fuels depletion and environmental degradation [2,3]. Biodiesel that is produced from Used Cooking Oil (UCO) has lately been tested in diesel engines, providing satisfactory results.…”

Quality Characteristics of Biodiesel Produced from Used Cooking Oil in Southern Europe

The potential of households’ used cooking oil (UCO) recycling for biodiesel production is massive. This study aims to promote the shift from UCO inappropriate disposal to sustainable recycling. UCO is classified as municipal waste under the code 20 01 25 (edible oils and fats), according to the European Waste Catalogue. Inappropriate UCO disposal increases the operating cost of wastewater treatment, the risk of groundwater contamination, as well as the greenhouse gas emissions that are associated with its biodegradation. Recycling UCO-to-biodiesel offers a sustainable solution in the exploitation of a problematic waste and its transformation into an energy resource, thus contributing to the reduction of environmental pollution and fossil fuel dependence. This paper includes critical recommendations in order to overcome bottlenecks to successfully promote the UCO-to-biodiesel chain. Quality control of the biodiesel—produced exclusively from UCO—was performed according to the European Standard EN 14214 and the results are presented in the paper. The analysis studies the outcomes from four Southern European countries (Spain, Portugal, Italy, and Greece), which hold the top four places in annual per capita olive oil consumption in the European Union (EU).

“…The results showed that using KOH and methanol gave better results than using NaOH and ethanol. Abed et al [9] researched the effects of cooking-oil biodiesel on engine performance and exhaust emissions of a Kirloskar make, single cylinder, four strokes, and direct injection diesel engine with a developing power of 5.775 kW at 1500 rpm. They have found that thermal efficiency of waste cooking-oil biodiesel were lower than that of diesel fuel and specific fuel consumptions were higher.…”

In this study, the biodiesel obtained from the waste olive oil by transesterification method has been mixed with a 30% of diesel fuel as volume and tested with a single cylinder direct injection diesel engine. The main purpose of this study is to obtain purer biodiesel from waste olive oil using methyl alcohol (CH3OH) and sodium hydroxide (NaOH) as catalyst in the transesterification method and research performance, combustion and emission characteristics in detail in a direct injection diesel engine. The combustion, engine performance and exhaust emission values have been also compared with diesel fuel. The test engine was operated at a constant speed of 2200 rpm and different engine loads such as 3.25 Nm, 7.5 Nm, 11.25 Nm, 18.75 Nm. According to the experimental results, the thermal efficiency of biodiesel is lower by about 1% to 5% than diesel. CO is lower about 37.5 % with biodiesel than that of diesel at 18.75 Nm. CO2 is higher 41% with biodiesel than diesel at 11.25 Nm. NOx was measured 9.5% higher than diesel fuel at 18.75 Nm. Soot emissions decreased by 37.5% compared to diesel.
