This article estimates greenhouse gas emissions and global warming factors resulting from collection of municipal solid waste to the transfer stations or landfills in Istanbul for the year of 2015. The aim of this study is to quantify and compare diesel fuel consumption and estimate the greenhouse gas emissions and global warming factors associated with municipal solid waste collection of the 39 districts of Istanbul. Each district’s greenhouse gas emissions resulting from the provision and combustion of diesel fuel was estimated by considering the number of collection trips and distances to municipal solid waste facilities. The estimated greenhouse gases and global warming factors for the districts varied from 61.2 to 2759.1 t CO2-eq and from 4.60 to 15.20 kg CO2-eq t-1, respectively. The total greenhouse gas emission was estimated as 46.4E3 t CO2-eq. Lastly, the collection data from the districts was used to parameterise a collection model that can be used to estimate fuel consumption associated with municipal solid waste collection. This mechanistic model can then be used to predict future fuel consumption and greenhouse gas emissions associated with municipal solid waste collection based on projected population, waste generation, and distance to transfer stations and landfills. The greenhouse gas emissions can be reduced by decreasing the trip numbers and trip distances, building more transfer stations around the city, and making sure that the collection trucks are full in each trip.

Greenhouse gas emissions resulting from municipal solid waste management activities and the associated climate change impacts are getting great attention worldwide. This study investigates greenhouse gas emissions and their distribution during waste collection and transport activities in the Dammam region of Saudi Arabia. Greenhouse gas emissions and associated global warming factors were estimated based on diesel fuel consumption during waste collection and transport activities. Then, waste collection and transport data were used to parameterise a mechanistic collection model that can be used to estimate and predict future fuel consumption and greenhouse gas emissions. For the collection and transport of municipal waste in the study area, the average associated total greenhouse gas emissions were about 24,935 tCO2-eq. Global warming factors for three provinces were estimated as 25.23 kg CO2-eq t-1, 25.04 kg CO2-eq t-1, and 37.15 kg CO2-eq t-1, respectively. Lastly, the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) modelling system was used to estimate the atmospheric dispersion of greenhouse gas emissions. Model results revealed that the maximum daily greenhouse gas concentrations ranged between 0.174 and 97.3 mg m-3, while annual average greenhouse gas concentrations were found to be between 0.012 and 27.7 mg m-3 within the study domain. The highest greenhouse gas concentrations were observed for the regions involving the municipal solid waste collection routes owing to their higher source emission rates.

The edge required by renewable technologies is provided by a simplification of the energy supply train. This simplification consists in no longer eating animals. Animals have upside-down energy returned on energy invested values (EROIs), with up to 30 times as much energy having to be put into raising them as we get out of them through eating them or their products. At one time, when our fossil fuels sported extraordinarily high EROIs—100:1 in some cases—we could afford to take this sort of hit on our food-based energy supply. Now, however, we can no longer afford to do so. Moreover, the results of this grossly inefficient energy exchange are rising greenhouse gas emissions. By no longer eating meat, we can reduce greenhouse gas emissions by roughly 14%. Importantly, much of this reduction will be in methane and nitrous dioxide, which have very high global warming potential relative to carbon dioxide.

Many studies have been performed to compare different straw-returning methods that could provide environmental benefits. However, few studies have focused on the greenhouse gas emissions from straw returning under winter water-stored fields (flooded conditions) and winter fallow fields (non-flooded conditions), which are the common land use types after the rice harvest in southern China. Thus, in the present microcosm incubation experiment, CO2, CH4 and N2O emissions were compared under flooded and non-flooded soil conditions, following straw incorporation. Straw application stimulated CO2 cumulative emission, and this effect was exacerbated by flooding (1818 and 4271 mg kg–1 under non-flooded and flooded conditions, respectively). Although the application of straw can mitigate N2O cumulative emissions under flooded conditions (10 152 μg kg–1 without and –51 μg kg–1 with straw incorporation, respectively), higher CO2 and CH4 production was detected (4271 and 149.20 mg kg–1 for CO2 and CH4 cumulative emissions, respectively). In contrast, straw application under non-flooded conditions had a relatively low global warming potential value (1836 mg CO2 Eq kg–1). Consequently, winter fallow field is recommended after the integrated application of straw and nitrogen fertiliser because of its low global warming potential. However, different strategies may be required for long-term reduction in global warming potential values.
