The present study investigates the different approaches of biodiesel production by exploiting low cost feedstocks such as organic wastes of frying oils (WFO) and wastes of beef fats (WBF). The aim was to compare not only two different sources of waste raw materials but also different approaches of biodiesel production. Biodiesel which refers to fatty acid methyl esters (FAME) was produced by both chemical and enzymatic transesterification. The characterization of the biodiesel produced by both approaches was performed according to the European standard EN 14214. The results showed that the biological method gave a richer FAME biodiesel through the catalysis of whole-cell lipase. However, for the chemical method, better biodiesel physicochemical properties were observed for the two raw materials. Therefore, it would be interesting to compromise by optimizing the biological biodiesel production approach in order to obtain a better quality in coherence with EN 14214 requirements.

Abstract Hermetia illucens L. (the black soldier fly) has received increased attention because of its great potential in converting organic waste into a renewable resource. The prepupae have high proportions of proteins and fats and can serve as feedstuff for livestock and as feedstock for biodiesel production. With the goal to upgrade the conversion of low-value organic wastes into high-value proteins and fat on a large scale, the effects of the feedstuffs food waste, pig manure, chicken manure, and cow dung on the reproductive potential and nutrient composition of H. illucens were evaluated. The intrinsic rate of increase of H. illucens fed food waste (0.1249 d−1) was significantly greater than the rate of those fed pig manure (0.1167 d−1), chicken manure (0.1154 d−1), and cow dung (0.1049 d−1). The ash content of H. illucens fed food waste (30.8 g·kg−1 lyophilized prepupa matter (LPM)) was significantly lower than that of those fed chicken manure (37.6 g·kg−1 LPM) and cow dung (49.5 g·kg−1 LPM). The contents of crude fat, 372.4 g·kg−1 LPM, and protein, 436.9 g·kg−1 LPM, in prepupae fed food waste were the highest among the four treatments. The reproductive performance and prepupal nutrient composition indicated that food waste was the most suitable feed for H. illucens. The results from this study further demonstrate that the prepupae of H. illucens have great potential for use as a protein and fat source in animal feeds and as biodiesel material.

The conversion of organic wastes into biodiesel has become an attractive solution to address waste surplus problems and energy depletion. Oleaginous insects can degrade various organic wastes to accumulate fat-based biomass, thus serving as a potential feedstock for biodiesel production. Therefore, the use of insects fed on organic waste for biodiesel production has increasingly attracted considerable investigations. In recent years, different insect species have been studied for their efficiency in converting various organic wastes and for producing biodiesel from their fat. Several methods have been developed for biodiesel production from insects to improve yields and reduce production costs and environmental impacts. This review summarizes the latest findings of the use of insects for converting organic wastes into biodiesel. The production processes and fuel properties of biodiesel produced from insects are also discussed.

The limited fossil reserves, spiraling price and environmental impact due to usage of fossil fuels leads the world wide researchers’ interest in using alternative renewable and environment safe fuels that can meet the energy demand. Biodiesel is an emerging renewable alternative fuel to conventional diesel which can be produced from both edible and non-edible oils, animal fats, algae etc. The society is in dire need of using renewable fuels as an immediate control measure to mitigate the pollution level. In this work an attempt is made to review the requisite and access the capability of the biodiesel in improving the environmental degradation.

Glycerol as a byproduct of biodiesel production was approximately formed 10% of the biodiesel weight. Impurities which contained in the glycerol such as catalyst, soap, methanol, water, salt, and matter organic non glycerol (MONG) have a significant effect on the glycerol concentration. So, it is necessary to treat the impurities. The purpose of this study is to know the effect of chloroform to glycerol purification process with acidification method using hydrochloric acid as pretreatment process. This research was begun with acid addition to the glycerol to neutralize the base content and to split the soap content into free fatty acid and salt, that are more easily separated from glycerol. Then the process was continued with extraction by the solvent chloroform using the variable of test volume ratio (v/v) (1:1, 1:1.5, 1:2)  and the extraction time (20, 40, and 60 minutes). The results showed that the more volume of solvent used, gave less extraction time to produce high purity of glycerol. The highest purity produced in this study amounted to 90,9082% is obtained at the ratio of the volume solvent (v/v) 1:1 with extraction time 60 minutes.
