Biomass composting with gaseous carbon dioxide capture

Abstract

Biomass carbon removal and storage (BiCRS) technologies must scale rapidly to mitigate climate change via the removal of carbon dioxide (CO2) from the atmosphere. BiCRS technologies passively concentrate atmospheric CO2...

Utilization of CO2-captured poly(allylamine) as a polymer surfactant for nanoarchitecture production in a closed CO2 cycle

“…To reduce atmospheric CO 2 , numerous efforts employing various innovative methods have been made, including the reduction of CO 2 through photochemical, 17–19 electrochemical 20–23 and biological approaches 24 into valuable compounds such as formic acid, formaldehyde, methanol and hydrocarbons; the co-reduction with nitrate to produce urea; 25 the incorporation of CO 2 into polymer main chains via copolymerization; 26–28 and composting with biomass. 29,30 These methods offer new avenues for fixing CO 2 and producing materials composed of it. However, these methods have not yet been effective enough to significantly reduce atmospheric CO 2 concentrations.…”
