Comparative Review

Recent interest in alternative energy sources, particularly biofuels from biomass, is becoming increasingly evident due to energy security and environmental sustainability concerns, such as depletion of conventional energy reserves and carbon footprint effects, respectively. Existing fuels (e.g., biodiesel and ethanol) are neither sustainable nor cost-competitive. There is a need to integrate the recent advanced manufacturing approaches and machine intelligence (MI) techniques (e.g., machine learning and artificial intelligence), targeted on the midstream segment (i.e., pre-/post-conversion processes) of biomass-to-biofuel supply chains (B2BSC). Thus, a comparative review of the existing MI approaches developed in prior studies is performed herein. This review article, additionally, proposes an MI-based framework to enhance productivity and profitability of existing biofuel production processes through intelligent monitoring and control, optimization, and data-driven decision support tools. It is further concluded that a modernized conversion process utilizing MI techniques is essential to seamlessly capture process-level intricacies and enhance techno-economic resilience and socio-ecological integrity of B2BSC.

The recent boom and collapse of the corn ethanol industry calls into question on the long-term sustainability of biofuels and traditional approaches to biofuel systems design. Compared with petroleum based transportation fuel production, biofuel production systems are so closely connected and heavily influenced by natural systems that they have to deal with high degrees of complexity, variability and unpredictability. Accordingly, a fundamental change in design philosophy is necessary for long-term viability of biofuel production. The new approach requires the system to be designed not for a narrowly defined efficiency (both economic and ecological), but for resilience (indicated by characteristics such as diversity, efficiency, cohesion and adaptability) to absorb unexpected disruptions and changes. Also, biofuel systems must be endowed with transformability to allow for “creative destruction” when current transportation fuels are eventually supplanted by new vehicle technologies and/or mode of transportation. This paper addresses important concepts in the design of coupled engineering-ecological systems (i.e. resilience, adaptability and transformability) that determine future system trajectories at multiple scales. In addition, several emerging biofuel conversion technologies are examined from a resilience perspective. It is suggested that the thermo-chemical conversion technologies may be preferable for biofuel production from resilience aspect. However, multiple technologies may increase the diversity and flexibility of the entire industry. This paper calls for the development of quantitative metrics for resilience assessment (similar to life cycle assessment for environmental sustainability) of industrial system, which are critical for integrating resilience into technology development and system design.

Microalgal Biomass

Subcritical water extraction (SWE) technology has been used for the extraction of active compounds from different biomass materials with low process cost, mild operating conditions, short process times, and environmental sustainability. With the limited application of the technology to microalgal biomass, this work investigates parametrically the potential of subcritical water for high-yield extraction of biochemicals such as carbohydrates and proteins from microalgal biomass. The SWE process was optimized using central composite design (CCD) under varying process conditions of temperature (180–374°C), extraction time (1–20 min), biomass particulate size (38–250 μm), and microalgal biomass loading (5–40 wt.%).Chlorella vulgarisused in this study shows high volatile matter (83.5 wt.%) and carbon content (47.11 wt.%), giving advantage as a feedstock for biofuel production. The results showed maximum total carbohydrate content and protein yields of 14.2 g/100 g and 31.2 g/100 g, respectively, achieved under the process conditions of 277°C, 5% of microalgal biomass loading, and 5 min extraction time. Statistical analysis revealed that, of all the parameters investigated, temperature is the most critical during SWE of microalgal biomass for protein and carbohydrate production.

The abundance of nutrient accumulation in rhizosphere soils has placed the rhizosphere as an “epicenter” of bacterial concentrations. Nonetheless, over the years, little attention has been given to bacterial inoculants and soil-like substrates. The reason is that many farmers and experiments have focused on chemical fertilizers as an approach to improve plant growth and yield. Therefore, we focused on assessing the application of rhizosphere soil and its associated bacteria for biotechnological applications. This review has been structured into major subunits: rhizosphere soil as a treasure trove for bacterial community concentration, biodegradation of lignocellulose for biofuel production, rhizosphere soil and its bacteria as soil amendments, and the role of rhizosphere soil and its bacteria for bioremediation and biofiltration. Hence, the efficient use of rhizosphere soil and its bacteria in an environmentally friendly way can contribute to healthy and sustainable environments.

ABSTRACT The pursuit for waste recovery has been the best way to contribute to environmental sustainability. The mix of sewage sludge (SS) from Sewage Treatment Plant with diatomaceous material containing oil (DE), used as a filter in biofuel production, can form a substrate rich in minerals and organic matter through vermicomposting. Therefore, this study aimed to produce vermicompost using worms, Eisenia foetida, from a pre-compost (PC) of sewage sludge and garden pruning residues mixed with different proportions of DE in relation to PC: 0; 7.53; 15.06; 22.59; and 30.12% v/v. The design was randomized complete blocks with five treatment replicates. The chemical characteristics of the vermicompost were analyzed after a period of four months. The proportion of up to 30.12% v/v of DE met the criteria established for agriculture uses, registration and marketing of the product as organic compost in accordance with the Normative Instructions SDA 27/2006 and 25/2009 from the Ministry of Agriculture.

The high quantity of nutrients accumulated in termite mound soils have placed termite mound as a ‘gold mine’ for bacteria concentrations. However, over the years, not much attention has been given to the bacteria present in termite mound soil. This is because many studies have focused on approaches to manage termites which they see as menace to agricultural crops and buildings. Therefore, we aimed to evaluate the potential application of termite mound soil material and its bacteria for biotechnological purposes. This review has been grouped into four key parts: The termite mound as hotspot for bacterial concentration, the degradation of lignocellulose for biofuel production, termite mound soil as a soil amendment, and the role of termite mound soil and its bacteria in bioremediation and bio-filtration. Therefore, the effective usage of the termite mound soil material and its bacteria in an ecofriendly manner could ensure environmental sustainability.

Environmental sustainability requirements and rising energy demands, as well as the depletion of conventional energy resources and environmental deterioration as a result of abrupt climate change, have redirected scientists' focus. For sustainable development, look for renewable sources of green and clean energy. Bioenergy is a great alternative because it may be used to meet a variety of energy needs with the right conversion technology. This overview covers all aspects of biofuels (bioethanol, biodiesel, and butanol) and the criteria for their long-term viability. The focus is on the most recent breakthroughs in biofuel production, emphasizing the role of nanotechnology. In addition, a slew of studies is being conducted on developing strategies for process optimization, such as integration methodologies, less energy-intensive distillation processes, and microbe bioengineering talked about. This can assist in making biofuel production in a real-world market more economically and environmentally viable.
