Overview of Carbon Capture Technology: Microalgal Biorefinery Concept and State-of-the-Art

Alternatively, bio-sequestration of CO2 making use of microalgal cell manufacturing facilities has become an appealing way of recycling CO2 into biomass through photosynthesis which in turn can be used for the production of bioenergy and various other value-added products. Recent technoeconomic evaluations and life-cycle assessments of microalgae-based production systems have recommended that the only feasible way for scaling up the manufacturing is to completely utilize the biomass in an integrated biorefinery set-up where every valuable part is extracted, refined and valorized. This article gives a quick yet extensive evaluation of the present carbon sequestration and usage modern technologies, concentrating mainly on biological CO2 capture by microalgae in the context of bio-refinery. The paper discusses various products of microalgal biorefinery and intends to examine the opportunities, challenges and present modern of microalgae-based CO2 bioconversion, which are essential to the sustainability of this technique in terms of the environment in addition to the economy.

In vivo genotoxicity of nitramines, transformation products of amine-based carbon capture technology

Chemical absorption with amines is becoming the most advanced reduction technology for post-combustion capture of CO2 from fossil fuel power plant. Although whole organism bioassays showed that nitramine poisoning with death was reduced, the genotoxicity evaluation disclosed different results, with ethanolnitramine located to be more genotoxic than dimethylnitramine by 3 orders of size. At the cheapest ethanolnitramine concentration, 84 % DNA damages was observed, whereas 100 mg/L dimethylnitramine was called for to cause 37 % DNA damages. Fish revealed to > 3 mg/L ethanolnitramine had practically no DNA left in their red cell. The big distinction in genotoxicity observed in between both nitramine substances highlights the risk of inferring poisoning from structurally comparable substances for environmental threat assessment, and on the other hand shows the relevance of substance certain assessments.
