Greenhouse Gas Emissions From Biofilters for Composting Exhaust Ammonia Removal

Frontiers in Bioengineering and Biotechnology, 2022
Emissions of odorous compounds, such as ammonia (NH3), from composting have negative agronomic and environmental impacts. A biofilter is widely used for NH3 removal, with one of its potential detrimental by-products being nitrous oxide (N2O), which is a ...

Removal of greenhouse gas in biofilter using organic and inorganic media

Vietnam Journal of Science, Technology and Engineering, 2021
A biofilter using organic (compost) and inorganic (pumice, porous silica pellet or poremat) media was applied to the removal of methane (CH4) and nitrous oxide (N2O) to minimize the impact of off-gasses from municipal solid waste disposal global.

Greenhouse gas removal in agricultural peatland via raised water levels and soil amendment [PDF]

Biochar
Peatlands are an important natural store of carbon (C). Drainage of lowland peatlands for agriculture and the subsequent loss of anaerobic conditions had turned these C stores into major emitters of greenhouse gases (GHGs).

Feasibility of Solar Updraft Towers as Photocatalytic Reactors for Removal of Atmospheric Methane–The Role of Catalysts and Rate Limiting Steps

Frontiers in Chemistry, 2021
Due to the alarming speed of global warming, greenhouse gas removal from atmosphere will be absolutely necessary in the coming decades. Methane is the second most harmful greenhouse gas in the atmosphere.

Straw return alleviates the greenhouse effect of paddy fields by increasing soil organic carbon sequestration under water-saving irrigation

Agricultural Water Management, 2023
The comprehensive greenhouse effect depends on the trade-off between greenhouse gas (GHG) emissions and soil organic carbon sequestration (SOCS) of paddy fields.

An emission pathway classification reflecting the Paris Agreement climate objectives

Communications Earth & Environment, 2022
Greenhouse gas emissions pathways compatible with the Paris Agreement simultaneously pursue warming of less than 1.5 °C, very likely never exceed 2 °C and achieve net zero greenhouse gas emissions by the second half of the century.

N2O emission and control strategy in different wastewater treatment processes [PDF]

E3S Web of Conferences, 2019
N2O (Nitrous oxide) is a strong greenhouse gas, and wastewater treatment process is one of the important artificial sources of N2O. Controlling N2O production and discharge in wastewater treatment process is beneficial to alleviate the greenhouse effect.

Coupled nitrification and N2 gas production as a cryptic process in oxic riverbeds

Nature Communications, 2021
The N cycle involves complex, microbially-mediated shuttling between ammonium, nitrite and nitrate, with climatically important greenhouse gas byproducts. Here the authors use isotope labeling experiments in river sediments and find a cryptic new step in

Research on Status and Outlook of Using Different Solvents for CO2 Capture in a Rotating Packed Bed [PDF]

E3S Web of Conferences, 2021
This study investigates the removal efficiency of carbon dioxide by aqueous absorbents containing monoethanolamine (MEA), piperazine(PZ), diethylenetriamine(DETA) and ionic liquids in a rotating packed bed. The performance of an absorbent was assessed in
