Concerns about biogas from landfills are reviewed in terms of biogas generation, composition, and elimination. Biogas is mainly composed of methane and carbon dioxide but it also contains a few hundred non-methane organic compounds. The solutions available to reduce its harmful effects on the environment and on human health are valorization as electricity or heat, flaring, or biofiltration. The main parameters affecting the biofiltration of methane are reviewed: temperature, moisture content, properties of the packing material, nutrient supply, oxygen requirements, formation of exopolysaccharides, and gas residence time. An analysis is performed on the co-metabolic properties and the inhibition interactions of the methane-degrading bacteria, methanotrophs.

The Great Artesian Basin (GAB) in Australia is one of the largest subterranean aquifer systems in the world. In this article we venture into the subterranean “resource environment”’ of the Great Artesian Basin and ask whether new insights can be provided by social analyses of the “vertical third dimension” in contemporary contests over water and coal seam gas. Our analysis makes use of a large number of publicly available submissions made to recent state and federal government inquiries, augmented with data obtained through ethnographic fieldwork among landholders in the coal seam gas fields of southern Queensland. We examine the contemporary contest in terms of ontological politics, and regard the underground as a challenging “socionature hybrid” in which the material characteristics, uses, and affordances of water and coal seam gas resources in the Great Artesian Basin are entangled with broader social histories, technologies, knowledge debates, and discursive contests.

Recovering energy from waste offers dual benefits – a) improved waste management, and b) provision of reliable energy to households, institutions and commercial entities. In this report, we present a socioeconomic assessment of three energy business models (briquette manufacturing, on-site (public toilet) energy generation, and agro-waste electricity generation) based on feasibility studies carried out in the city of Kampala, Uganda. We assess the potential economic, environmental and social impacts of waste-to-energy business models taking into consideration a life cycle of emissions to provide decision makers with the overall costs and benefits of the models to society versus a business-as-usual scenario.

In the anticipated water scarcity and global warming scenario; it is imperative to identify suitable irrigation scheduling strategy in paddy fields for increasing water productivity and mitigating greenhouse gas (GHG) emissions. We conducted a two year (dry season of 2014 and 2015) field experiment for irrigation scheduling based on tensiometric measurement of soil water potential (SWP)in order to quantify temporal and seasonal variations in GHGs emissions and their trade off relationship at five levels of SWPs viz. SWP 1 (-20 kPa), SWP 2 (-30 kPa), SWP 3 (-40 kPa), SWP 4 (-50 kPa) and SWP 5 (-60 kPa), in addition to the traditional practice of growing flooded rice (CF). Fluxes of methane (CH4) and nitrous oxide (N2O) during the growing period were measured using manual closed chamber-gas chromatograph and the carbon dioxide (CO2) flux was measured using an infrared CO2 analyzer. A significant decrease in seasonal cumulative CH4 emission (30–60.2%) was recorded at different SWPs as compared to CF. In contrast, emission of CO2 and N2O increased by 12.9–26.6% and 16.3–22.1% respectively at SWPs 1 and 2; conversely, a significant decrease in emissions of these gases were observed at higher SWPs (SWPs 3–5). Among different SWP treatments, irrigation scheduling at SWP 2 maintained yield at par with CF with water saving of 32.9–41.1% and reduced CH4 emission (43–44.1%). However, due to increase in CO2 and N2O emission at SWP 2, there was no significant reduction in global warming potential (GWP) as compared with CF. Among different rice growth stages GHGs emission were predominant during vegetative growth stage. Regression relationship of GHGs emission with key soil parameters was employed to predict seasonal emissions of GHGs from paddy field. The results of this study suggest that scheduling irrigation at SWP 2 can be an effective strategy in order to save water, maintain rice yield and mitigate CH4 emission from direct seeded paddy fields in eastern India, however further research is needed to identify suitable management strategy for reducing CO2 and N2O emissions at SWP 2 in order to reduce the GWP.

In recent decades, academia has elaborated a wide range of technological solutions to recover water, energy, fertiliser and other products from municipal wastewater treatment plants. Drivers for this work range from low resource recovery potential and cost effectiveness, to the high energy demands and large environmental footprints of current treatment-plant designs. However, only a few technologies have been implemented and a shift from wastewater treatment plants towards water resource facilities still seems far away. This critical review aims to inform decision-makers in water management utilities about the vast technical possibilities and market supply potentials, as well as the bottlenecks, related to the design or redesign of a municipal wastewater treatment process from a resource recovery perspective. Information and data have been extracted from literature to provide a holistic overview of this growing research field. First, reviewed data is used to calculate the potential of 11 resources recoverable from municipal wastewater treatment plants to supply national resource consumption. Depending on the resource, the supply potential may vary greatly. Second, resource recovery technologies investigated in academia are reviewed comprehensively and critically. The third section of the review identifies nine non-technical bottlenecks mentioned in literature that have to be overcome to successfully implement these technologies into wastewater treatment process designs. The bottlenecks are related to economics and value chain development, environment and health, and society and policy issues. Considering market potentials, technological innovations, and addressing potential bottlenecks early in the planning and process design phase, may facilitate the design and integration of water resource facilities and contribute to more circular urban water management practices.

Greenhouse gas emissions from urban rivers play a crucial role in global carbon (C) cycling, this is tightly linked to dissolved C in rivers but research gaps remain. The effects of urbanization and anthropogenic land-use change on riverine dissolved carbon dynamics were investigated in a temperate river, the River Kelvin in UK. The river was constantly a source of methane (CH4) and carbon dioxide (CO2) to the atmosphere (excess concentration of CH4 ranged from 13 to 4441 nM, and excess concentration of CO2 ranged from 2.6 to 230.6 µM), and dissolved C concentrations show significant spatiotemporal variations (p < 0.05), reflecting a variety of proximal sources and controls. For example, the concentration variation of dissolved CH4 and dissolved CO2 were heavily controlled by the proximity of coal mine infrastructure in the tributary near the river head (~ 2 km) but were more likely controlled by adjacent landfills in the midstream section of the rivers main channel. Concentration and isotopic evidence revealed an important anthropogenic control on the riverine export of CO2 and dissolved organic carbon (DOC). However, dissolved inorganic carbon (DIC) input via groundwater at the catchment scale primarily controlled the dynamics of riverine DIC. Furthermore, the positive relationship between the isotopic composition of DIC and CO2 (r = 0.79, p < 0.01) indicates the DIC pool was at times also significantly influenced by soil respiratory CO2. Both DIC and DOC showed a weak but significant correlation with the proportion of urban/suburban land use, suggesting increased dissolved C export resulting from urbanization. This research elucidates a series of potentially key effects anthropogenic activities and land-use practices can have on riverine C dynamics and highlights the need for future consideration of the direct effects urbanization has on riverine C dynamics.

Farm activities contribute to approximately one-third of Greenhouse Gas (GHG) emissions. Most of the GHG in the atmosphere comes from carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The main objective of this research is to investigate direct and indirect GHG emission in five different agroecosystems, contrasted by tillage agricultural, farm practices (oat and maize-fava and vetch).CO2, N2O y CH4 concentrations were measured using two closed static chambers. Total biomass and production costs were determined. Indirect emissions were calculated from fuel used in producing and packing of synthetic fertilizers and herbicide, and sheep manure mineralization. The results showed that CO2 was the gas that most contributes to GHG emissions followed by the CH4 and NO2. The agrosystem with reduce tillage and synthetic inputs had the highest emissions (979 CO2 eq kg ha-1). Agrosystems using synthetic inputs (conventional and reduce tillage) showed higher indirect emissions (958 and 856 CO2 eq kg ha-1 respectively). Maize in monoculture produced more than the systems with rotation or intercropping. Reduced tillage with intercropping and organic inputs was the most expensive to produce but had the least gas emission per dollar invested and per kilogram of biomass produced while conventional tillage agrosystems with organic or synthetic inputs stored little carbon in the soil, produced less biomass per unit area and presented higher CO2 eq emissions per unit of biomass.
