Biogas potential from cow manure by Yohaness, Meaza Tadesse

“…A batch type reactor was then operated at 37 °C to investigate the methane potential of the manures. The result showed that enteric methane emission of the cows was weakly positively correlated with methane potential of their manure (R=0.2). …”

Process performance of anaerobic co-digestion of raw and acidified pig slurry by Moset, Verónica, Cerisuelo, Alba, Sutaryo, S., Moller, H. B.

“…The optimal inclusion level of acidified pig slurry in anaerobic co-digestion with conventional slurry was 10%, which promoted anaerobic methane yield by nearly 20%. Higher inclusion levels caused methane inhibition and volatile fatty acids accumulations in both experiments. …”

Exploring socio-ecological niches for forages in climate-smart dairy systems in Rwanda by Qingye, Huang

“…Impacts on milk yield and enteric methane emission for scenarios of grass and legume integration in banana fields were simulated through the Ruminant model. …”

Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment by Sellin, Jessica

“…A retention time of four days resulted, however, in a specific methane production which was 42-48% lower than at Henriksdal WWTP at thermophilic (55 °C) and mesophilic (37 °C) temperatures. …”

Transitioning to more sustainable livestock systems through agricultural breakthroughs by International Livestock Research Institute

“…Though technologies such as methane inhibitors may have a role in systems where feed is regulated, in pasture and grazing led systems the only effective approach to reduce methane emissions is through supporting an increase in climate-smart livestock practices.…”

Integrated production of bioethanol and biogas from agricultural residue : comparison of pretreatment methods using mass flow and energy yields analysis by Dererie, Debebe Yilma

“…Soluble sugars were analyzed by HPAE-PAD (Dionex); ethanol, glycerol and acetate by HPLC. Methane yields were estimated using measured biogas pressure and methane content of the biogas as analyzed by gas chromatography. …”

Greenhouse Gas Emissions from Intermittently Flooded (Dambo) Rice under Different Tillage Practices in Chiota Smallholder Farming Area of Zimbabwe by Nyamadzawo, George, Menas W, Chirinda, Ngonidzashe, Mujuru, Lizzie, Smith, J.L.

“…Rice production has been identified as one of the major sources of greenhouse gases, especially methane. However, data on the contributions of rice towards greenhouse gas emissions in tropical Africa are limited. …”

Breeding rice for a changing climate by improving adaptations to water saving technologies by Heredia, Maria Cristina, Kant, Josefine, Prodhan, M. Asaduzzaman, Dixit, Shalabh, Wissuwa, Matthias

“…Unlike other crops, rice is a main contributor to greenhouse gas emissions due to methane emissions from flooded paddy fields. Climate change can therefore be addressed in two ways in rice: through making the crop more climate resilient and through changes in management practices that reduce methane emissions and thereby slow global warming. …”

Metanogenreduktion : en hållbar lösning på växthuseffekten? by Tufvesson, Karin

The Diverse Benefits of Alternate Wetting and Drying (AWD) by Allen, Justin, Sander, Björn Ole

“…Standard production practices using continuous flooding (CF) are resource intensive and contribute significant global methane emissions. The technique of alternate-wetting-drying (AWD) uses a more controlled irrigation strategy that can significantly reduce methane emissions as well as water use and pumping costs. …”

Environmental impacts of alternative co-substrates for biogas production : a comparative life cycle assessment by Croxatto Vega, Giovanna Catalina

“…A sensitivity analysis, where different methane yield potentials were tested for each co-substrate, was performed and the results proved to be robust. …”

The green impact of livestock-based nutrient management by Ehui, Simeon K.

“…Livestock and manure management contribute about 16 percent of the total annual production of methane worldwide. Emissions are highest where both animal production and feed quality are low, indicating that research to increase productivity through use of improved feeding strategies would reduce methane emissions from ruminants. …”
