Recently, intensifying energy crises accompanying ecological due to the decline in fossil-fuel reserves and extensive greenhouse gas emissions have triggered exploration of renewable substitutes for petro-diesel. In this scenario, biodiesel is best alternative non-renewable finite conventional fuels its cost-effectiveness, sustainability, renewability, biodegradability, eco-friendly nature. Hence, current research was designed utilize scanning electron microscopy investigate identify micro-morphological characteristics selected seed-bearing crops. Light-microscopy (LM) indicated discrete variations macro-morphological characters such as seed shape (ovoid, ovate, oblong, semi-spheroid, or discoid), size (3.5–14 mm length 2.25 6.5 width), color (yellow black), number seeds per kilogram (from 6000 260,000). Chemical extraction via Soxhlet apparatus resulted estimation oil content within range 20.3–48.0% (wt./wt.), FFA (0.63–6.91 mg KOH/g), maximum product, i.e., 98% yield achieved. Multivariate analysis principal component (PCA) done using PAST 3 software similarities differences among factors/variables. SEM examination exhibited ultra-morphological distinct variation cell-wall ornamentation; hilum occurrence, position, level; wall-sculpturing ruminate, verrucate, wrinkled, striate; cell arrangement (anticlinal periclinal); margins. To conclude, could be an advanced technique disclose ultra-micromorphological oil-bearing crops providing a convenient way scientists determine correct identification, authentication, classification.

Membrane technology has been embraced as a feasible and suitable substitute for conventional time- energy-intensive biodiesel synthesis processes. It is ecofriendly, easier to run regulate, requires less energy than approaches, with excellent stability. Therefore, the present study involved application of highly reactive recyclable Titania-based heterogeneous nanocatalyst (TiO2) production from nonedible Azadhiracta indica seed oil via membrane reactor, since easily widely accessible rich content (39% w/w). The high free fatty acids (6.52 mg/g KOH) was decreased 1% two-step esterification. Following esterification, transesterification performed using TiO2 under optimum conditions, such 9:1 methanol–oil molar ratio, 90 °C reaction temperature, 2 wt.% catalyst loading, an agitation rate 600 rpm, yield optimized through response surface methodology (RSM). contains 68.98% unsaturated (61.01% oleic acid, 8.97% linoleic acid) 31.02% saturated (15.91% palmitic 15.11% stearic acid). These transformed into respective methyl esters, total up 95% achieved. analyzed advanced characterization techniques like gas chromatography–mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR), whereas characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive (EDX), (FT-IR). Due its physicochemical properties, Azadirachta recommended feedstock production. Moreover, it concluded that effective high-quality liquid fuel in which could be optional green route cleaner bioenergy, eventually leading sustenance, robustness, resilience will aid developing holistic framework integrated waste management.

Perspective Chapter: Sustainable Management and Utilization of Agricultural Waste – Innovations, Challenges, and Future Prospects

IntechOpen eBooks, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Agricultural waste (crop residues and animal manure) is a significant byproduct of farming activities. It holds potential for sustainable agriculture, renewable energy production, environmental conservation. However, traditional disposal challenges persist, leading to air pollution soil degradation. Innovative approaches include converting agricultural into bioenergy like bioethanol biogas producing biochar from residues, which improves health, water retention, nutrient availability while sequestering carbon. also finding applications in industries. Integrating industrial processes not only adds value but reduces reliance on raw materials fossil fuels wood. In livestock farming, crop are critical as feed bedding, particularly resource-constrained regions. While their nutritional content often low, treatment methods can improve digestibility. By integrating cutting-edge technologies supportive policies, it possible transform burden resource, paving the way more future.
