“…Various reports have mentioned that the atmospheric CO 2 concentrations have increased from around 280 ppm to 368 ppm over the past 200 years [13], contributing up to 50% to the global temperature increase known as greenhouse effects. The global warming causes sea level to rise and various climate anomalies linked to global warming, including floods and droughts [5,[14][15]. Considering these high impacts, it is necessary to perform strategic activities which aim at reducing atmospheric CO 2 concentrations.…”

“…One of the primary requirements for photosynthesis is atmospheric CO 2 . Microalgae are generally characterized by their relatively high photosynthetic efficiencies compared to various terrestrial plants and have been proposed as an alternative way of reducing carbon dioxide emissions into the atmosphere [15]. As photosynthetic organisms, microalgae are well adapted to capturing ambient CO 2 .…”

The global warming issue caused mainly by carbon dioxide (CO 2 ) has triggered various efforts to reduce excess amount of CO 2 emitted into the atmosphere. A viable option is to utilize biomass production potential of microalgal consortium in aquatic ecosystem that constantly requires CO 2 to perform photosynthesis. This study aims to provide scientific contributions to the development of environmental studies, particularly of using microalgal consortiums as carbon capture and storage (CCS) agent by engineering their culture conditions. A number of studies analyzing biological reduction of atmospheric CO 2 by using CO 2 absorption capability of terrestrial plants have been facing many difficulties. Compared to various terrestrial plants, microalgae are generally considered photosynthetically more efficient. Exploitation of microalgal capability has numerous advantages, including their faster regeneration time, ability to grow in less space than terrestrial plants, and because the cultivation of microalgae can be done on a small-scale or large-scale operation, under controlled conditions, and is independent to climatic changes. Taking into account long-term advantages, this study is a preliminary study which is expected to be able to provide information and feedback regarding integrated microalgal culture system that may lead to alternative solutions of ecofriendly and sustainable environmental management technology that are capable of mitigating environmental problems caused by CO 2 (as greenhouse gas) emissions. Hence, the results of this research could be implemented by building urban microalgal ponds in efforts to develop sustainable cities in terms of CO 2 emission reduction in urban areas.

“…By contrast, 1 kg of BOD removed by photosynthetic oxygenation requires no energy inputs, and it produces enough algal biomass for fuel generation (Oswald 2003). Pedroni et al (2001) observed better results for microalgae in the wastewater treatment as compared to conventional processes such as activated sludge. Filamentous algae/cyanobacteria can be as effective as microalgae, and they may be harvested relatively easily by filtration.…”

Water security may be regarded as a first step toward achieving food and energy security. Efficient use of fresh water resources and recycling of wastewater after proper treatment are viewed as tools to achieve water sustainability. Sugar industry can have good potential to treat and reuse its effluents. This potential is not realized by prevailing effluent treatment technologies because of high capital and operation cost of treatment process. More upon, these technologies require substantial amount of energy (electricity) as well as chemicals and labors. We have therefore focused on the development of a technology that would help to overcome these limitations. The algaSpirulina-was our choice to (1) treat the effluent and (2) use the sugar mill effluent as its growth medium. Experiments using Spirulina at secondary treatment stage showed 91 % reduction in chemical oxygen demand in 108-h treatment time. Further, biochemical analysis of Spirulina harvested from the sugar mill effluent treatment tanks revealed that the harvested biomass has high protein levels. Spirulina is well known for its usage as a protein supplement and therefore can be used as an additional source of revenue generation.

“…More recently, others have also confirmed that flue gas can be used to grow algae without harmful effects and at least one commercial algae cultivator on Hawaii is using CO2 from a small power plant (Pedroni et al, 2001 Chlorophyceae Bacillariophyceae +++ ++ dissolved NOx can be used by algae as a nitrogen source. The amount of flue gas needed per hectare will differ per species of algae, and will also vary throughout the day with light intensity and temperature, thus needs to be optimized for each specific application.…”

Microalgae have high photosynthetic efficiency that can fix CO2 from the flue gas directly without any upstream CO2 separation, and concomitantly produce biomass for biofuel applications. Microalgae population studies were conducted in a batch mode experiments at power plant site of Chamois, Missouri in "USA". The experiments were conducted in different period (June to December 2011) of time. This study evaluated the effect of several heavy metals that are present in flue gases on the algae, focusing on the growth and accumulation of lipids in the algae that can be converted to biodiesel. The genus Scenedesmus presented the greatest richness of species and number of counted individuals in the flue gas ponds compare than non-flue gas treatment ponds. Among the diatomaceae the genus Navicula sp, Nitizchia sp and Synedra sp. presented the next subdominant richness in the ponds. The last results of counted green algae Ulothrix sp and Coelastrum sp were least number of cells reported in these ponds. The heavy metal-contaminated in flue gas and also enter into the microalgae biomass population. Comparative studies were carried out by flue gas and control system of open ponds. Control system of microalgae population was represented in less amount of heavy metals compare than flue gas ponds.
