“…The options for carbon capture vary from solvent-based technologies such as Absorption/desorption using Monoethanolamine (MEA) [46,47], to underdeveloped methods such as oxyfuel combustion [48], membrane separation [49,50], nanomaterial sorbents [51] and chemical looping [52,53]. In parallel, intensive research is devoted to CO 2 utilization for producing fuel and products [54], and among them microalgae cultivation has gained significant research interest [55,56]. The diverse array of the algae research activities includes microalgae strain selection and lipid yield enhancement, [57][58] microalgae cultivation and dewatering [59], oil-extraction and different upgrading methods [60][61][62][63][64][65][66][67] With the aim of enhancing the overall biofuel yields and improving the environmental impacts, the present research proposes an integrated biorefinery comprising of biomass pyrolysis, in addition to solvent-based carbon capture and utilization through microalgae cultivation.…”

Biomass-derived fuels can contribute to energy sustainability through diversifying energy supply and mitigating carbon emissions. However, the biomass chemistry p`oses an important challenge, i.e., the effective hydrogen to carbon ratio is significantly lower for biomass compared to petroleum, and biomass conversion technologies produce a large amount of carbon dioxide by-product. Therefore, CO2 capture and utilization will be an indispensable element of future biorefineries. The present research explores the economic feasibility and environmental performance of utilizing CO2 from biomass pyrolysis for biodiesel production via microalgae. The results suggest that it is possible to increase biomass to fuel conversion from 55% to 73%. In addition, if subsidies and fuel taxes are included in the economic analysis, the extra produced fuel can compensate the cost of CO2 utilization, and is competitive with petroleum-derived fuels. Finally, the proposed integrated refinery shows promise as CO2 in the flue gas is reduced from 45% of total input carbon to 6% with another 19% in biomass residue waste streams.

Microalgae transform CO2 into a broad portfolio of biomolecules, and thus should be considered as a valuable biotechnological platform. Despite several research programs and global efforts to establish a sustainable microalgae-based industry, most applications have not transcended academic boundaries. This limitation raises from the high transformation costs when target products are biofuels or fertilizers. Microalgae biorefinery emerges as an alternative to improve economic competitiveness, as Under such a model scope, the process inputs come from industrial waste, while biomass exploitation prioritizes the highest value molecules followed by extraction of less valuable compounds. This review describes a wide range of microalgae exploitation schemes focused on new uses of its constituents, while discussing emerging technologies designed to improve production and efficiencies as well.Keywords: microalgae; biorefinery; biofuels; fertilizers; active biomolecules. Biorefinerías de microalgas: aplicaciones actuales y nuevas tecnologías en desarrolloResumen Las microalgas transforman el CO2 en un amplio portafolio de biomoléculas, por lo cual, son consideradas una valiosa plataforma biotecnológica. A pesar de múltiples programas de investigación y esfuerzos globales para establecer una industria sostenible basada en microalgas, la mayoría de las aplicaciones potenciales no han trascendido las fronteras académicas. Esta limitación se debe a los altos costos en la transformación del producto principalmente cuando se obtiene compuestos económicos como biocombustibles y fertilizantes. La biorefinería de microalgas surge como alternativa para incrementar la competitividad económica. En este modelo, los insumos del proceso provienen de residuos industriales, mientras que la explotación de la biomasa inicia con las moléculas de alto valor y finaliza con los compuestos menos valiosos. En esta revisión se describe un amplio abanico de esquemas de explotación de microalgas enfocado en nuevos usos de sus constituyentes. Además, se exploran las tecnologías emergentes destinadas a aprovechar esta biomasa de una manera más versátil y eficiente.

“…Microalgae are a robust microorganism which can survive and thrive in different mode; photo-autotrophic, mixotrophic, heterotrophic and some mixture of complex metabolism to survive in harsh culture condition [5 -8]. The ability of microalgae to conduct photo-autotrophic showed that microalgae has the potential to be applied in the process of carbon capture and storage (CCS) [9].…”

Carbon capture and storage (CCS) through biological approach has attracted much attention as global warming and climate change issue becomes a worldwide agenda. Energy production industry from coal in Malaysia produced 50.661 million metric tons of carbon dioxide in 2012, and the trend showed it will keep increasing year by year. CCS through biological approach can be done by microalgae which are versatile microorganism which perform photosynthesis process that can store CO2 in the biomass form. In this study, microalgae strains were isolated from the native environment nearby a coal-fired power plant, where samples were collected in different canal in which pre-treated flue gases are discharged. The microalgae strains were identified by both morphological and molecular approaches. Result from 18s rRNA gene sequencing showed that the isolated strains is Chlorella sp. with similarity 99% with Chlorella sp. SAG 211-18. The identified strains of microalgae then cultivated with three concentration of CO2 (ambient air, 1% and 5%) and the growth rate showed 0.4017 day -1 , 0.5752 day -1 and 0.4427 day -1respectively. Different concentration of CO2 (ambient air, 1% and 5%) showed that the isolated strains yielded 1.005gL -1 , 1.101gL -1 and 1.035gL -1 respectively. This study also showed that with different concentration of CO2, the sequestration rate is ranging from 1% to 4.3%.Keywords: microalgae, isolation, purification, DNA sequencing Abstrak Pemerangkapan dan penyimpanan karbon (CCS) melalui pendekatan biologi telah menarik minat pengkaji disebabkan masalah pemanasan dan perubahan iklim global. Pada tahun 2012 sahaja, Malaysia telah menghasilkan 50.661 juta ton metrik karbon dioksida hasil daripada penghasilan tenaga yang bersumberkan arang batu, dan tahun demi tahun penghasilan karbon dioksida dijangkakan akan terus meningkat. Pemerangkapan dan penyimpanan karbon melalui pendekatan biologi boleh dilakukan oleh mikroalga yang merupakan mikroorganisma unggul di mana ianya berupaya menjalankan proses fotosintesis dalam menukarkan karbon dioksida ke dalam bentuk biojisim. Dalam kajian ini, mikroalga dipencilkan daripada habitat asal yang merupakan terusan bagi air penyejuk untuk stesen janakuasa arang batu. Mikroalga yang diperoleh, dikenalpasti menggunakan kaedah pengecaman secara morfologi dan molekul. Hasil keputusan pengenal pastian molekul menggunakan kaedah penjujukan genom 18s rRNA mendapati, mikroalga yang berjaya dipencilkan adalah Chlorella sp. yang mempunyai persamaan sehingga 99% dengan Chlorella sp. SAG 211-18. Mikroalga yang telah menjalani proses identifikasi kemudiannya dikultur menggunakan 3 kepekatan karbon dioksida yang berbeza (CO2 pada udara persekitaran, CO2 1% dan CO2 5%) dan hasil menunjukkan kadar pertumbuhan masing-masing adalah 0.4017 hari -1 , 0.5752 hari -1 , dan 0.4427 hari -1 . Pada kepekatan CO2 yang berbeza (CO2 pada udara persekitaran, CO2 1% dan CO2 5%), hasil biojisim yang terkumpul daripada pengkulturan mikroalga masing-masing
