Production of biohydrogen from crude glycerol in an upflow column bioreactor

Valorization of crude glycerol and eggshell biowaste as media components for hydrogen production: A scale-up study using co-culture system

“…Bioconversion of CG to hydrogen (H 2 ) is a widely explored approach in comparison to the production of other value-added products (Dounavis et al, 2015;Fountoulakis & Manios, 2009). H 2 production can be carried out with renewable and sustainable technologies with combined waste treatment in comparison to chemical methods associated with consumption of fossil fuels (Sivagurunathan et al, 2016).…”

Biorefinery for Glycerol Rich Biodiesel Industry Waste

“…With bacteria being immobilized to the biofilm reactor, it resulted in achieving an H 2 productivity level of 107 L/kg waste glycerol. Glycerol consumption was found to vary from 73 to 96 %, depending upon the operation period [54].…”

Proposed design of a composting facility for the treatment of municipal waste with built-in deodorization system (in Western Macedonia, Greece)

“…However, this treatment method is relatively rare at present (it is only part of waste management strategies in Germany, Austria, Belgium and Denmark, with some application on mixed or residual waste in France, Spain and Italy, though a small-scale plant is in operation in the UK). The principal advantage of the process is the biogas production from controlled anaerobic digestion (comprising principally carbon dioxide and methane, which is capable of combustion to generate energy) (Dounavis et al 2015;Dounavis et al 2016). Another by-product of this process is a semi-solid residue, referred to as a digestate which could be used for agricultural / horticultural purposes after further treatment (normally through composting).…”
