“…Upstream, the selection, harvesting, collection logistics and pre-processing of selected biomass determines the size of the production facility which, in turn will affect the number and geography of the assets and the subsequent distribution networks and the increasingly important impacts of overall carbon-emissions [ 2 , 3 ], changes in land-use or agriculture systems [ 75 ], and consequences for global biodiversity [ 146 ]. Consequently, new microbial routes to biofuels should routinely be assessed by rigorous stage-appropriate life-cycle and techno-economic assessments (LCA and TCA, respectively) in which the benefits derived from each innovation and the potential costs or diverse impacts of its production and use are clearly stated and quantified [ 147–149 ].…”

Decarbonisation of the transport sector is essential to mitigate anthropogenic climate change. Microbial metabolisms are already integral to the production of renewable, sustainable fuels and, building on that foundation, are being re-engineered to generate the advanced biofuels that will maintain mobility of people and goods during the energy transition. This review surveys the range of natural and engineered microbial systems for advanced biofuels production and summarises some of the techno-economic challenges associated with their implementation at industrial scales.

“…There are many solutions for each link, so the economy of each production scheme is different [92]. With different raw materials, the equipment, raw, and subsidiary material consumption and detoxification methods of the pretreatment process are also different, and the utilization of glucose, xylose, and arabinose for alcoholic fermentation by yeast is also different [93,94]. However, it is very important for lignocellulosic ethanol industry to make a rigorous and rational economic evaluation under the scale of industrialization.…”

Lignocellulose is an abundant and renewable biomass that is mainly composed of cellulose, hemicellulose and lignin. The development and utilization of lignocellulosic ethanol is an effective way to solve the energy problem/crises, In addition, lignocellulosic ethanol industry can play a significant role in controlling environmental pollution and extending agricultural industrial chain; however, it has not been able to realize large-scale industrialization due to the limitation of both biotechnology and economy. This review first introduces industrialization status of lignocellulosic ethanol, and then focuses on the progress of practical technology and analyzing the economic feasibility of the second-generation bioethanol plant; finally, the future development trend of the industry was prospected. To summarize, continuous technological innovation is needed in vital steps such as pretreatment, enzymatic hydrolysis, and fermentation. Meanwhile, for making the cellulosic ethanol industry truly economically competitive, we also need to achieve interdisciplinary, cross-domain integration innovation, such as the construction of raw material collection and storage system, in situ producing special enzyme system, high-value utilization of raw material components, developing a closely integration of biomass refinery with mature equipment and overall industrialization programs, etc. It is hoped that this review can provide a useful reference for the industrialization of second-generation bioethanol.

“…Chloroplast biotechnology has the potential to help alleviate the main challenges of this century by lowering renewable biofuels cost, increasing food production, and increasing productivity per plant. Currently, the cost of renewable energy through biofuels is not competitive against fossil fuels ( Medipally et al, 2015 ; Mu et al, 2020 ; Lo et al, 2021 ; Scown et al, 2021 ). The current goal of the Bioenergy Technologies Office Advanced Algal Systems program within the Department of Energy is $2.5–3 gallon of gas equivalent for renewable algal biofuels by 2030, while current gasoline prices remain relatively low at $2.18 per gallon ( BETO Publications, 2020 ; Fuel Prices, n.d. ).…”

Photosynthetic organisms are sources of sustainable foods, renewable biofuels, novel biopharmaceuticals, and next-generation biomaterials essential for modern society. Efforts to improve the yield, variety, and sustainability of products dependent on chloroplasts are limited by the need for biotechnological approaches for high-throughput chloroplast transformation, monitoring chloroplast function, and engineering photosynthesis across diverse plant species. The use of nanotechnology has emerged as a novel approach to overcome some of these limitations. Nanotechnology is enabling advances in the targeted delivery of chemicals and genetic elements to chloroplasts, nanosensors for chloroplast biomolecules, and nanotherapeutics for enhancing chloroplast performance. Nanotechnology-mediated delivery of DNA to the chloroplast has the potential to revolutionize chloroplast synthetic biology by allowing transgenes, or even synthesized DNA libraries, to be delivered to a variety of photosynthetic species. Crop yield improvements could be enabled by nanomaterials that enhance photosynthesis, increase tolerance to stresses, and act as nanosensors for biomolecules associated with chloroplast function. Engineering isolated chloroplasts through nanotechnology and synthetic biology approaches are leading to a new generation of plant-based biomaterials able to self-repair using abundant CO2 and water sources and are powered by renewable sunlight energy. Current knowledge gaps of nanotechnology-enabled approaches for chloroplast biotechnology include precise mechanisms for entry into plant cells and organelles, limited understanding about nanoparticle-based chloroplast transformations, and the translation of lab-based nanotechnology tools to the agricultural field with crop plants. Future research in chloroplast biotechnology mediated by the merging of synthetic biology and nanotechnology approaches can yield tools for precise control and monitoring of chloroplast function in vivo and ex vivo across diverse plant species, allowing increased plant productivity and turning plants into widely available sustainable technologies.
