Biogas is obtained from the breakdown of biomass by microorganisms and bacteria in absence oxygen. considered a renewable source energy, similar to solar energy wind energy. can be produced or bio-waste; thus, it environmentally friendly. suspended monoxide decomposition process anaerobic fermentation decomposable materials such as agricultural manure, sewage, municipal waste, green waste (gardens parks), plant material products. natural that leaves effective effects on nature industries. This gas organic materials, including animal food sewage. Fertilizers produce biogas through digestion (ie without presence oxygen). mixture gases generated decaying biodegradable Its main contents are 50–70 % methane (CH4) volume, 30–50 carbon dioxide (CO2), traces other gases, like hydrogen sulfide (H2S) water vapor (H2O). CO2, H2S, content may affect performance life conversion devices; consequently, their removal before end-use essential for improving quality biogas. combination an ideal option making The most important advantages (production reduction amount discarded pathogens, containing matter into high fertilizer, protection vegetation, soil, water, increasing productivity field livestock agriculture) It also one disadvantages (incomplete small technologies, impurities, effect temperature production, unsuitable urban dense areas, not affordable). For economical use biogas, carried out under controlled conditions relatively simple device called reservoir. review summarizes current state-of-the-art presents future perspectives related production. Moreover, historical retrospective sector early years its development till recent advancements give outlook opportunities opening up optimization.

Abstract Rising fuel security challenges can be addressed by utilizing potential and renewable energy feedstocks such as microalgae. This study focuses on biodiesel production from Desmodesmus armatus NCIM 5583 optimizing biomass productivity lipid content. Independent optimization experiments were performed to key growth parameters, viz., light intensity, photoperiod, NaNO 3 concentration. Growth conditions with 40 µmol/m 2 /s 20 h L:04 D 0.25 g/L concentration exhibited highest of 26.51 ± 1.1 mg/L d yield 45.1 0.16% (w/w). Further, CaO bionanocatalyst synthesized using waste eggshells characterized SEM, EDX, FT-IR, XRD. The results SEM EDX confirmed the structural elemental composition Ca O main elements. XRD revealed crystalline nature a particle size 28.74 nm. Lipid transesterification catalyst yielded 84 0.2% (w/w) FAME was analyzed 1 H NMR, 13 C GC–MS. presence methyl ester group, implying conversion microalgal lipids biodiesel. findings this demonstrate D. for application catalysts.

Polysaccharides (PSs) are the most abundant carbohydrates in nature, performing essential biological functions such as immune system regulation, structural support, and cell communication. PSs from marine microalgae have gained increasing attention due to their diverse activities potential applications various fields, including human health sector. These natural macromolecules, primarily composed of glucose, xylose, galactose, rhamnose, fucose, exhibit bioactive properties influenced by molecular weight, sulfation degree, complexity. Microalgal can function antiviral, antimicrobial, antioxidant, immunomodulatory, antitumor agents, making them promising candidates for pharmaceutical nutraceutical applications. Additionally, physicochemical make valuable ingredients cosmetics, serving hydrating UV protectants, anti-ageing compounds. The production presents a sustainable alternative terrestrial plants, be cultivated under controlled conditions, ensuring high yield purity while minimizing environmental impact. Despite potential, challenges remain optimizing extraction techniques, enhancing characterization, scaling up commercial This review provides an overview principal eukaryotic possible use cosmetic Challenges address implement products improve wellbeing also discussed.

Abstract Rare Earth Elements (REEs) are indispensable in contemporary technologies, influencing various aspects of our daily lives and environmental solutions. The escalating demand for REEs has led to increased exploitation, resulting the generation diverse REE-bearing solid liquid wastes. Recognizing potential these wastes as secondary sources REEs, researchers exploring microbial solutions their recovery. This mini review provides insights into utilization microorganisms, with a particular focus on microalgae, recovering from such ores, electronic waste, industrial effluents. outlines principles distinctions bioleaching, biosorption, bioaccumulation, offering comparative analysis limitations. Specific examples microorganisms demonstrating efficacy REE recovery highlighted, accompanied by successful methods, including advanced techniques enhancing strains achieve higher Moreover, explores implications bio-recovery, discussing methods mitigate pollution. By emphasizing microalgae promising biotechnological candidates recovery, this not only presents current advances but also illuminates prospects sustainable resource management remediation.

Food and other bio-waste management is an integral part of urban development living. Composting a common practice in most developed countries, while open burning landfilling widely used waste low middle income countries. The outputs composting include compost, heat, leachate, off-gas. off-gas consists carbon dioxide (CO2), methane, nitrous oxide, water vapor, ammonia volatile organic compounds. CO2, although biogenic could contribute to climate change mitigation if the emissions are controlled. CO2 sequestration using microalgae has been reported as viable alternative geological storage. sources microalgal cultivation ambient air, off-gas, combustion flue gas, wastewater aeration syngas, biogas. Carbon from can be controlled environment agriculture instead commercially produced alternative, or air. This review examines available information on dynamics, particularly evolution, challenges prospects use cultivation, ensuring circularity process. recommends utilization direct air extraction. However, achieving higher concentration relative oxygen challenging. While efforts made towards reduction greenhouse gas during composting, near zero essential enhancing cultivation. should achieved without compromising compost quality such germination index chemical demand/heavy metals efficiency.
