On-site CO2 bio-sequestration in anaerobic digestion: Current status and prospects

نویسندگان

چکیده

The advantages of anaerobic digestion (AD) technology in organic solid waste treatment for bioenergy recovery are evidenced worldwide. Recently, more attention has been paid to on-site biogas research, as well biogenic CO2 sequestration from AD plant, promote “carbon neutral”. Single-phase and two-phase system can be incorporated with various bioconversion technologies through H2 mediated (in-situ ex-situ upgrading), or other emerging strategies fixation without exogenous injection; these include in-situ direct interspecies electron transfer reinforcement, electromethanogenesis, off-gas reutilization. existing potential scenarios bio-sequestration within the framework reviewed perspectives metabolic pathways, functional microorganisms, limitations on reaction kinetics. This review concluded that is a promising solution reduce greenhouse gas emissions increase renewable energy recovery.

Erratum to: Detoxifying CO2 Capture Reclaimer Waste by Anaerobic Digestion

The decrease in toxicity of carbon capture reclaimer monoethanolamine (MEA) waste (MEAw) during anaerobic degradation of such waste together with easily degradable organics was investigated. Samples were collected from a bioreactor at steady state with 86 % organic chemical oxygen demand removal at room temperature, which had been running on MEAw for 2 years. The toxicity of the digester efflue...

A Review on Anaerobic Digestion, Bio-reactor and Nitrogen Removal from Wastewater and Landfill Leachate by Bio-reactor

The nitrogen removal from wastewater and landfill leachate has become a vital part of the overall treatment process because nitrogen compounds have the significant impact on the environment. Generally, biological nitrogen removal is used for nitrogen elimination from wastewater. In the last years, newly advanced anaerobic reactor systems such as up flow anaerobic sludge blanket (UASB), anaerobi...

Mammary ductoscopy: current status and future prospects.

BACKGROUND Mammary ductoscopy (MD) allows direct visualisation of the mammary ducts using sub-millimetre fiberoptic microendoscopes inserted through the ductal opening onto the nipple surface. The sharp clear magnified images are viewed on a video monitor. Such scopes have working channels that allow irrigation and ductal lavage for cytological analysis. MD can be performed under local anaesthe...
