“…These results highlight the significance of the share of the energy sources; impacts could shift from one category to another. Other studies [89,90] reveal similar results in which the use of renewable energy sources in the electricity background of future scenarios significantly lessens the environmental impacts.…”

Thanks to food technology, the production of cold tomato soups such as salmorejo, a traditional Spanish dish, has become industrialised. Thermal treatments play an important role in ready-to-eat meals, prolonging their shelf-life. Radiofrequency (RF) heating is less energy-intensive than conventional heat exchangers and has been successfully used to pasteurise food; novel applications, however, provide results at laboratory or pilot scale, so conclusions might not be translatable to industry. In this study, a prospective Life-Cycle Assessment of salmorejo pasteurised using RF was performed to highlight the relevance of upscaling and to compare its environmental impacts with those of conventional pasteurisation. “Gate-to-gate” results show that the pilot has greater environmental impacts due to its greater energy consumption, as thermal energy is not recovered. The packing and landfill of organic waste exhibit the highest impacts at industrial scale. RF technology does not imply significant environmental improvements versus conventional pasteurisation. Potential changes in the energy background of future scenarios have relevant consequences in the environmental impacts. “Farm-to-factory-gate” analysis highlights ingredients and tomato valorisation as the most impacting stages. The prospective LCA of scaled up scenarios constitutes a tool for environmental screening in food ecodesign, contributing to Sustainable Development Goal 12.

“…In addition to bioethanol, there are also partial studies on the conversion of biomass into bioethanol and biobutanol processes. The studies cover the LCA of biomethanol [137,138] and biobutanol [139,140] from feedstock, pretreatment, production process, and application to assess the potential of alternatives for bioethanol production.…”

Energy consumption from transport has been increasing at a fast rate and become a major sector, which takes 29% of total global energy demand. Since transport energy consumption primarily relies on fossil fuels, it has resulted in serious carbon emissions and environmental degradation. Moreover, the volatility prices of fossil fuel and unstable international security have attracted keen interest for many developing and industrialized countries looking for sustainable and clean alternatives. Liquid biofuels, including but not limited to bioethanol, biodiesel, bio-jet fuel, are considered as the most promising alternative and more expansive role in powering sustainable transport, for its carbon neutral and low-emissions properties. Liquid biofuels contribute 4% of transport in 2020 and have been foreseen to continuously grow. Liquid biofuels can be produced by diverse technologies and commercialized in various ways, easy-adapt to technical and policy challenges. Major challenges include technical bottleneck, initial and operational cost, byproduct treatment, and associated environmental concern. This paper critically reviews: (1) Categories and production of different liquid biofuels; (2) Application scenarios of liquid biofuels; (3) Environmental impact assessment of liquid biofuels; (4) Opportunities and challenges of liquid biofuels; (5) Future perspectives. Each type of liquid biofuel requires specific production processes and has a strong correlation with biomass raw materials. Liquid biofuels find extensive applications in transportation, aviation, and other functional domains. In addition, the life cycle assessment of liquid biofuels is carried out from the numerous aspects of raw materials, pretreatment, production process, and application. Furthermore, this study analyzes the related policies, highlighting the challenges associated with the unstable supply of clean energy, raw materials, and quality control. Finally, the future perspectives of liquid biofuels were presented. This comprehensive review aims to provide a systematic understanding of liquid biofuels, covering their production and applications from multiple perspectives, while offering insights into future developments.

Biofuel production using cyanobacteria aims to maintain the sustainability of an ecosystem with minimum impact on the environment, unlike fossil fuels, which cause havoc on the environment. The application of biofuel as an alternative energy source will not only help in maintaining a clean environment and improving air quality but also decrease harmful organic matter content from aquatic bodies. Cyanobacteria are valuable sources of many novel bioactive compounds, such as lipids and natural dyes, with potential commercial implications. One of the advantages of cyanobacteria is that their biochemical constituents can be modified by altering the source of nutrients and growth conditions. Careful changes in growth media and environmental conditions altering the quality and quantity of the biochemicals and yield capacity have been discussed and analyzed. In the present review, the challenges and successes achieved to date in the commercial production of biofuel and its application in the transportation industry are discussed. The authors also focus on different types of feedstocks obtained from biomass, especially from cyanobacterial species. This review also discusses the selection of appropriate cyanobacterial species with merits and demerits in the post-harvesting process. In sum, the current review provides insight into the use of organic bioresources to maintain a sustainable environment.
