Special Issue Information

Dear Colleagues,

Climate change is already a major challenge for today’s society, and we have to rush for the implementation of a sustainable bio-based economy where biofuel must play a leading role altogether with other renewable energies. Such a challenge involves the sustainable replacement of fossil-derived fuels and energy by sustainable biofuels in the transport sector but also in the generation of residential and industrial heat and power. This energy transition needs a major societal effort all along the energy and fuel chain value, from biomass generation, conversion in integral biorefineries into biofuels and other co-products, logistics and supply in order to satisfy society’s needs. In this context, the development of biofuels from renewable resources is crucial in terms of a holistic sustainability where different dimensions such as social, health, environmental, climate change, economical, scientific, and technology development are being taken into account with a suitable policy to accelerate a circular bioeconomy in the near future. With this in mind, sustainable biofuels would impact the society and boost circular bioeconomy with minor environment and climate change concerns but improve welfare. The success of such an energy transition requires, however, a completely change of paradigm and a focus on healing our planet and society welfare, where the sustainable production and use of biofuels and co-products must play a leading role.

This Special issue aims to show recent advances in the development of sustainable biofuels all along the chain value. Promising feedstocks, processes, integral biorefineries, and uses in the transport sector and heat and power generation will be provided and discussed to give an in-depth overview of the state of the art with a broad spectrum of sustainable biofuels. For the sustainability of biofuel development, the Special issue will also address lifecycle and sustainability analysis of different production technologies and social and political interest in promoting biofuels. These facts make this Special issue very valuable for all society, i.e., social communities, biofuel companies, the scientific community, and decision makers.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Biofuels are an attractive alternative from polluting activities to low carbon ones. In this understanding, biodiesel has the potential to replace fossil diesel. Density is a relevant parameter of biodiesel to work out its quality. Density models lead to reducing the costly and time-consuming experimental measurements. We compiled two databases to prove a group contribution approach. For this purpose, the first database contained 1231 densities of 58 alkyl esters, while the second covered 696 densities of 16 pure biodiesel samples and 8 biodiesel blends. The group contribution method based on the molar volume was used to estimate the alkyl ester densities, while the mixing rule proposed by Kay was used to predict the biodiesel densities. The method developed here is easy to apply and provides excellent results, because an average absolute deviation of 0.29% was reached on the biodiesel density prediction. Full article

In this study, lignocellulosic material derived from guava tree pruning was used to make pellets in a laboratory machine. The following experiments were conducted to identify the properties of the biomass samples before the pelletizing process: chemical analysis, proximal analysis, elemental analysis, ash microanalysis and thermogravimetric analysis (TGA-DTG). The following analyses were performed on the densified material: moisture content, particle density, bulk density, impact resistance and calorific value. The guava pellets evaluated, with respect to open fires, mitigate the CO2, CO, CH4, HCNM, EC, OC and PM2.5 emissions. Emissions per unit of consumed energy were reduced by 8 times for PM2.5, almost 5 times for HCNM, 3 times for CH4, 7 times for CO, 2 times for CO2, 6 times with respect to EC and almost 30 times for OC. The results of the physical and energetic evaluation of the pellets indicate good potential for its use as a solid densified biofuel. Full article

Currently, Mexico is facing an energy transition, therefore updated policy regulations pertaining to the sustainable use of biomass are needed. In particular, policy that favors the sustainable use of biomass to produce energy and bioproducts to privilege climate change mitigation is needed. This review describes the use of maguey (Agave spp.) and nopal (Opuntia spp.; also known as “cactus”) for biofuel production, especially in marginal areas. Emphasis is given on documented case studies discussing features of production and cultivation for both maguey and nopal, in addition to their potential for fuel production. Environmental and social sustainability issues in terms of waste value and new opportunities as bioenergy feedstocks and byproducts are also discussed. Although the paper does not deeply describe aspects of biomass transformation, such as bioprocess configurations, it gives characteristics of production in addition to cultivation. Agave and Opuntia species may represent a suitable feedstock for biofuels, bioproducts, bioenergy and biorefineries, especially in dry lands (semi-arid and dry sub-humid), deforested areas, agroforestry systems and agricultural semi-terraces known as metepantle in Mexico.
