“…There is abundantly available waste everywhere: domestically, in municipalities, in industry, and the natural environment, and many more sources are yet to be discovered. The most studied wastes include banana peels, 39 coco‐pod husk, 14, 17 plantain peels, 40, 41 oil palm trunk, coconut husk, 42 coconut shell, 43 sugarcane bagasse, wood ash, 44 Lemna perpusilla Torrey, 45 rubber seed shell, 46 palm kernel shell, 47 banana peduncle, 48 Enterolobium cyclocarpum pod husk, 49 kola nut pod husk, 50 and tucuma peels 51 …”

“…It is therefore necessary to develop a database of biomass waste materials with effective catalytic potentials with a view to harnessing them for the development of heterogenous catalysis for biodiesel synthesis. The chances of soap formation during transesterification with biogenic generated catalysts are reported to be insignificant due to their high basic strengths 17, 51, 59 . To obtain improved catalytic strength of biogenic waste catalysts, calcination at high temperature is an important objective.…”

Biodiesel has the potential to contribute significantly to the elimination of the present global energy and climate change logjam, but its production and commercialization have been hindered by the diverse nature of the feedstocks used for production. This paper reviews the effectiveness of applying various types of crop and animal waste-derived catalysts together with innovative feedstock hybridization as an economically viable technique for biodiesel production. Feedstock challenges, availability, and sustainability for large-scale applications are addressed with a view to bridging the existing gaps. Challenges in the use of edible oils and algae oil sources and development remain, but the technique of feedstock hybridization appears to be very promising, innovative, and cost-effective for biodiesel production. The present state of biodiesel production could be improved by the application of simple and cost-effective technologies in the feedstock system. High free fatty acid (FFA) content is the major hurdle to the use of most oils, especially low-grade/advanced oil feedstocks, in biodiesel production. This could be addressed through technological application of feedstock hybrids and biogenic waste-derived heterogenous catalysts, and their biochemical modifications. Conventional technology for the large-scale application of inorganically derived catalysts in biodiesel production with various characteristic differences is presented. Heterogenous catalysts derived from biogenic wastes and their modification could be used to overcome associated problems with the use of inorganic catalysts in biodiesel production. Biogenic waste-derived heterogenous catalysts are renewable, available, eco-friendly, and cost-effective. Technological applications of heterogeneous catalysts derived from biogenic waste are outlined and reviewed, considering various materials and different modification techniques to identify appropriate options for scaling up development. This review also discusses fundamental considerations for the Review

“…Recently, the catalysts used have been replaced with more environmental friendly heterogeneous ones (Caetano et al, 2013;Mendonça et al, 2019). The catalysis process using heterogeneous catalysts is great interest because it has beneficial characteristics such as high selectivity, long catalyst life, easy recovery, repeatability, and temperature stability; the catalyst can also be easily separated from the reaction mixture (Climent et al, 2012;Santos et al, 2015).…”

A nanocomposite comprising cellulose and nanomagnetite based on rice husk cellulose was used as the catalyst for the formation of methyl esters from oleic acid as an alternative method for biodiesel production. The resulting nanocomposite properties supported by FTIR, XRD, SEM and TEM characterization revealed that nanomagnetite Fe3O4 had impregnated the acetylated nanocellulose. The nanomagnetite Fe3O4 obtained had an average size of 30 nm. The best conversion of oleic acid to methyl esters for the catalytic application of the nanocomposite was 89.21%, which was achieved at a reaction temperature of 60°C, reaction time of 5 hours, catalyst concentration of 1.5 wt.%, and ratio of oleic acid to methanol of 3:1. Kinetic analysis at different temperatures (40, 50, 60 and 70°C) was performed, and a low activation energy of 16.56 kJ/mole was obtained. These results indicate that the biopolymer-based nanocomposite utilizing nanocellulose from rice husks composited with inorganic Fe3O4 nanoparticles has good potential for use as a green biocatalyst, and the proposed reaction can be used as an innovative new method to produce biodiesel in the future.

Biocides Used as Additives to Biodiesels and Their Risks to the Environment and Public Health: A Review

et al. 2018

View full text Add to dashboard Cite

One of the advantages of using biodiesel and its blends with diesel oil is the lower levels of emissions of particulate matter, sulfur dioxide, carbon monoxide, among others, making it less harmful to the environment and to humans. However, this biofuel is susceptible to microbial contamination and biodeterioration. In this sense, studies on the use of effective low toxicity biocides are being carried out, and this work aims to present the latest information (2008–2018) available in the scientific databases, on the use of biocides in biodiesel, mainly concerning their toxicity to the environment and public health. The results showed that in relation to the control of microbial contamination, the current scenario is limited, with seven publications, in which the most studied additives were isothiazolinones, oxazolidines, thiocyanates, morpholines, oxaborinanes, thiocarbamates and phenolic antioxidants. Studies regarding direct experiments with humans have not been found, showing the need for more studies in this area, since the potential growth of biodiesel production and consumption in the world is evident. Thus, there are need for more studies on antimicrobial products for use in biodiesel, with good broad-spectrum activity (bactericidal and fungicidal), and further toxicological tests to ensure no or little impact on the environment.
