Water is the most valuable resource on planet. However, massive anthropogenic activities generate threatening levels of biological, organic, and inorganic pollutants that are not efficiently removed in conventional wastewater treatment systems. High (carbon, nitrogen, phosphorus), emerging chemical contaminants such as antibiotics, pathogens (namely antibiotic-resistant ones related genes) jeopardize ecosystems human health. Conventional systems entail several environmental issues: (i) high energy consumption; (ii) CO2 emissions; (iii) use chemicals or generation harmful by-products. Hence, microalgal (entailing one microalgae species, consortium with bacteria) agents towards has been seen an environmentally friendly solution to remove pollutants, coliforms antibiotic resistance genes. In recent years, authors have evaluated for different types wastewater, agricultural, municipal, industrial. Generally, can provide removal efficiencies of: up 99%, 90% total phosphorus, and/or organic carbon, respectively, through uptake mechanisms, antibiotics frequently found wastewaters, sulfamethoxazole, ciprofloxacin, trimethoprim azithromycin at 86%, 65%, 42% 93%, desirable mechanism, biodegradation. Although by species complex very strain-specific, it also possible attain coliform Escherichia coli 99.4% 98.6%, respectively. systems' effectiveness strongly relies biotic abiotic conditions, thus selection operational conditions critical. While combination selected (microalgae bacteria), ratios inoculum concentration allow efficient amounts biomass (that be further converted into products biofuels biofertilisers), factors pH, hydraulic retention time, light intensity CO2/O2 supply a crucial role removal, disinfection. some rationale must considered according purpose. alkaline pH induces hydrolysis faecal coliforms, decreases phosphates solubility formation ammonium from ammonia. Also, while increases E. Pseudomonas aeruginosa, well growth (and uptake), Enterococcus faecalis removal. Therefore, this review aims critical studies application pathogens; discussing feasibility, highlighting advantages challenges implementation process, presenting current case-studies applications

Abstract Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review of algal lignocellulosic with focus on products mechanisms, oil upgrading, combining anaerobic digestion, economy, life cycle assessment. Products include oil, gas, biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification transesterification, hydrotreatment, steam reforming, use supercritical fluids. We examined economic viability terms profitability, internal rate return, return investment, carbon removal service, product pricing, net present value. also reviewed 20 recent studies found that method highly influenced yield, ranging from 9.07 40.59% 10.1 41.25% biochar, 11.93 28.16% syngas. Feedstock type, pyrolytic temperature, heating rate, reaction retention time were main factors controlling distribution products. Pyrolysis mechanisms bond breaking, cracking, polymerization re-polymerization, fragmentation. Biochar residual forestry could sequester 2.74 tons dioxide equivalent per ton biochar when applied soil thus potential remove 0.2–2.75 gigatons atmospheric annually. The generation bio-oil process is estimated be economically feasible.

Carbon capture and sequestration (CCS) is a three-tier process- carbon capture, transport storage. The consists of pre-combustion, oxy-combustion post-combustion capture. Transport CO2 most viable through pipelines. biotic CO2storage occurs terrestrial or oceanic pathways can be simulated naturally artificially. abiotic/geologic storage achieved sequestering in depleting/depleted hydrocarbon reserves, deep saline aquifers mineral carbonation. At the district level, 64 out 641 districts (2013 government reports) accounted for ∼ 60% total emissions. Controlling emissions comes with challenge sustainable socio-economic growth country- demanding task economy. Indian organizations have made international collaborations. India holds substantial geological potential its basaltic rocks, coal seams, depleted oil soils, sedimentary basins. this point, no / clean development mechanism projects are operational country. next 10-15 years would very crucial to attain technological advancement deploy large-scale CCS projects.

Over the last several decades, concerns about climate change and pollution due to human activity has gained widespread attention. Microalgae have been proposed as a suitable biological platform reduce carbon dioxide, major greenhouse gas, while also creating commercial sources of high-value compounds such medicines, cosmetics, food, feed, biofuel. Industrialization microalgae culture valorization is still limited by significant challenges in scaling up production processes economic constraints productivity capacities. Therefore, boost resource usage efficiency required. This enhancement not only lowers manufacturing costs but enhancing long-term viability microalgae-based products. Using wastewater nutrient source great way costs. Furthermore, water scarcity one most important global challenges. In recent industrialization, globalization, population growth all impacted freshwater resources. Moreover, high amounts organic inorganic toxins disposal waste into rivers can severe impacts on animal health. cultures are sustainable solution tertiary quaternary treatments since they ability digest complex contaminants. review presents biorefineries based from angles, including potential for environmental remediation well applications bioenergy value-added biomolecule production. An overview current information technology discussion associated hazards opportunities bioeconomy highlighted.
