Ongoing intensification and specialisation of livestock production lead to increasing volumes of manure to be managed, which are a source of the greenhouse gases (GHGs) methane (CH4) and nitrous oxide (N2O). Net emissions of CH4 and N2O result from a multitude of microbial activities in the manure environment. Their relative importance depends not only on manure composition and local management...

A flare is a combustion device that uses air or steam to burn associated, unwanted or excess gases and liquids released during production or by pressure relief valves during unplanned over-pressuring of plant equipment in many industrial operations, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills. Several environmental problems caused by gas flaring such as ...

“United in Science” is the recent slogan of United Nations climate summit 2020. A collective effort institutional governance, energy resources utilization, foreign inclusion, and regional collaboration required for Sustainable Development Goal (SDGs) achieving a clean environment. In reaching this objective, study investigates sustainably Regulatory Quality (RQ), Energy Consumption per capita (...

Biofuels derived from microalgae have the potential to replace petroleum fuel and first-generation biofuel, but the efficacy with which sustainability goals can be achieved is dependent on the lifecycle impacts of the microalgae-to-biofuel process. This study proposes a detailed, industrial-scale engineering model for the species Nannochloropsis using a photobioreactor architecture. This proces...

The role of greenhouse gas emissions (GHG) from freshwater reservoirs and their contribution in increasing atmospheric GHG concentrations is actually well discussed worldwide. The amount of GHGs emitted at the air-water interface of reservoirs varies over time. The maximum is attained within 3 to 5 years after impoundment. In reservoirs older >10 years in boreal and semi-arid regions, GHG emiss...

G reenhouse gas emissions are fundamental both to the world’s energy system and to its food production. The production of CO2, the predominant gas implicated in climate change, is intrinsic to fossil fuel combustion; specifically, thermal energy is generated by breaking the chemical bonds in the carbohydrates oil, coal, and natural gas and oxidizing the components to CO2 and H2O. One cannot hav...

introduction earth's atmosphere plays an important role in preventing the temperature decrease. one of the principal factors of environmental pollution and the main source of earth's climate and biodiversity changes is greenhouse gas emissions from various sources, particularly agricultural sector. agriculture sector is considered as a major source of greenhouse gas sequestration, including me...

The ecological footprint (EF) commonly neglects the influence of other stressors than land use and CO2 emissions on the land area required for human activities. This study analyzes the relevancy of including nutrients and non-CO2 greenhouse gases in the EF assessment of products. The analysis was based on environmental information for 1,925 goods and services. Our findings suggest that within s...

s the scientifi c evidence of global climate change continues to accumulate (IPCC, 2007) and the predicted impacts of a warming planet become more widely known, national policies and international agreements designed to mitigate global warming have sought to strike a balance between environmental sustainability and economic achievement. Agriculture is at the center of this balancing act. On the...
